Introduction

South Africa’s refrigerated transport sector stands at an inflection point. For decades, diesel-powered transport refrigeration units have been the unquestioned standard—reliable, well-understood, and supported by extensive infrastructure. But a convergence of factors is now creating a realistic pathway to zero-emission operations that would have seemed implausible just three years ago.

The shift isn’t theoretical. In January 2024, the first 100% electric refrigerated trailer rolled onto the N1 between Johannesburg and Cape Town. By late 2025, that single unit had grown to a fleet of 16, collectively saving 102 tonnes of CO2 in their first year of operation. Elsewhere, South Africa’s largest retailer runs approximately 90% of its trailer fleet on solar-hybrid systems, saving R60 million annually in diesel costs. And in March 2025, the country’s first fully electric “bumper-to-bumper” cold chain trucks—electric tractor, electric refrigeration, e-axle trailer—entered commercial service.

These aren’t pilot projects gathering dust in corporate sustainability reports. They’re scaled operations with verified return on investment, running profitable routes and delivering measurable results.

For cold chain operators planning fleet replacement cycles over the next five to seven years, the question is no longer whether zero-emission technology works in South African conditions. The question is which technology fits which operation—and when the numbers make sense for your specific routes, cargo profiles, and capital position.

This article cuts through the marketing hype to examine what’s actually proven, what the real-world economics look like, and how operators can plan a practical transition by 2030.

The Technology Landscape: Four Pathways to Zero-Emission Refrigeration

Zero-emission refrigerated transport isn’t a single technology—it’s a family of approaches, each suited to different operational profiles. Understanding the distinctions is essential for making informed investment decisions.

Regenerative Axle Systems

The Thermo King AxlePower system represents a genuinely innovative approach to trailer refrigeration. Rather than drawing power from the tractor’s engine or a separate diesel generator, AxlePower captures kinetic energy from the trailer’s wheels as they roll. This energy is stored in a high-voltage battery pack and used to power the refrigeration unit.

The system is tractor-independent, meaning the trailer maintains temperature control regardless of what’s pulling it. It requires no grid connection to charge—the act of driving generates sufficient power. A diesel backup exists for emergencies but, in South African deployments, has been engaged less than 3% of the time.

For operators, the implications are significant. There’s no fuel cost for refrigeration on long-haul routes. Maintenance requirements drop substantially without a diesel engine to service. And the system has proven its resilience in ambient temperatures exceeding 40°C while maintaining constant cooling and uninterrupted airflow.

The technology is best suited for long-haul routes with consistent motion—the Johannesburg to Cape Town corridor being an ideal example. Stop-start urban delivery generates less kinetic energy, though the system still outperforms diesel alternatives in most scenarios.

Solar-Hybrid Systems

Solar-powered refrigeration has moved from experimental to mainstream in South Africa faster than many predicted. The concept is straightforward: roof-mounted solar panels charge lithium batteries that power the transport refrigeration unit, with diesel backup available when needed.

What makes the technology compelling is its economics. Operators report daily diesel savings of 4.8 litres per trailer, with return on investment achieved in approximately 1.4 years based on fuel savings alone. The Section 12B tax incentive—allowing a 125% deduction on solar installations—further improves the business case.

Technology has evolved rapidly. Six years ago, systems used 250W panels. Today, 420W panels are standard, with 600W options available. Battery capacity has increased 40-45% while physical size has decreased. These improvements translate directly to operational capability.

Solar-hybrid systems excel in multi-drop urban delivery where vehicles spend significant time stationary during loading and unloading. Rather than idling a diesel engine to maintain temperature, solar panels continue charging batteries while the truck is parked. The systems also eliminate noise during stops—increasingly important as deliveries extend into residential areas and night-time hours.

The technology works as a retrofit, allowing operators to upgrade existing trailers rather than replacing entire units. This makes solar-hybrid an accessible entry point for fleets beginning their decarbonisation journey.

Cryogenic and Liquid Nitrogen Systems

South Africa is recognised globally as a leader in cryogenic transport refrigeration—a fact that surprises many in the industry. The technology uses liquid nitrogen stored in a vessel beneath the load-box. When cooling is required, nitrogen is released and expands through pipes in the sidewalls into a heat exchanger. The warmed nitrogen is then released to atmosphere, with evaporator fans and controls powered by solar panels.

The result is zero on-road carbon emissions with exceptional temperature performance. A major South African supermarket retailer operates 300 liquid nitrogen trailer units nationally, primarily for deep-frozen distribution where the rapid pull-down capability of cryogenic systems offers advantages over mechanical refrigeration.

The limitation is infrastructure. Liquid nitrogen must be refilled at depots, similar to diesel. Unlike diesel, however, bulk nitrogen storage facilities don’t exist in every town. Industry participants note that establishing bulk depots in strategic locations—Bloemfontein is frequently cited—would unlock long-distance cryogenic haulage. Until that infrastructure exists, the technology remains best suited for routes with nitrogen availability at both ends.

Maintenance requirements are minimal without a diesel engine, and the systems operate silently. For operations with appropriate route profiles and access to nitrogen supply, cryogenic refrigeration offers a proven zero-emission pathway.

Full Battery-Electric Trucks with Electric Refrigeration

The most comprehensive approach electrifies the entire vehicle—tractor powertrain, refrigeration unit, and increasingly, the trailer axle for energy recovery. These “bumper-to-bumper” solutions eliminate all on-road emissions and represent the ultimate destination for zero-emission cold chain transport.

South Africa saw its first such deployment in March 2025 when Vector Logistics took delivery of two Volvo FH 6×4 battery-electric tractors paired with e-axle trailers and fully electrified refrigeration. The specifications are impressive: 665 horsepower, 2,400Nm of torque from three electric motors, and 540kWh of battery capacity providing 200-300 kilometres of range per charge.

The refrigeration system includes a diesel backup for emergencies, but the primary operation is entirely electric. Solar-powered charging stations at Vector’s distribution centres mean the entire energy chain can be renewable.

Full electric solutions are best suited for regional distribution operations where vehicles return to a home depot daily for charging. The 200-300km range is more than adequate for urban and peri-urban delivery routes. Long-haul applications await improvements in battery technology and charging infrastructure, though both are advancing rapidly.

Driver response has been notably positive. As one Volvo representative observed, drivers “definitely do not want to go back to diesel” after experiencing the smooth, quiet, vibration-free operation of electric trucks.

Technology Comparison

When evaluating these technologies, operators should consider several factors:

• Capital Cost: Full electric systems carry the highest upfront investment, followed by AxlePower, with solar-hybrid retrofits being most accessible. Cryogenic systems fall in the middle range.
• Operating Cost: All zero-emission technologies offer substantial savings over diesel. Solar-hybrid and AxlePower eliminate refrigeration fuel costs entirely during operation. Full electric eliminates both traction and refrigeration fuel. Cryogenic systems have ongoing nitrogen costs but no diesel expenditure.
• Range Limitations: AxlePower and solar-hybrid have no practical range limits—they function wherever the vehicle travels. Full electric is constrained to 200-300km between charges. Cryogenic range depends on nitrogen tank capacity and refill infrastructure.
• Infrastructure Requirements: Solar-hybrid and AxlePower require no external infrastructure. Full electric needs depot charging stations. Cryogenic requires access to liquid nitrogen supply.
• South African Maturity: Solar-hybrid is fully mature with thousands of units deployed. AxlePower is proven with expanding deployments. Cryogenic is proven but infrastructure-limited. Full electric is early-stage but operational.

Real-World Case Studies: Proven Results from South African Operators

Technology specifications matter less than operational results. The following case studies demonstrate what zero-emission refrigerated transport actually delivers under South African conditions.

Woolworths and DP World: AxlePower at Scale

The partnership between retailer Woolworths and logistics provider DP World has produced the most comprehensive AxlePower deployment in Africa. What began as a single trailer in January 2024 has expanded to 16 units by late 2025, with routes extending from the core Johannesburg-Cape Town corridor into Namibia.

The performance data is compelling. Across 146,000 kilometres logged, the system has operated in electric mode 97% of the time. The diesel backup—designed for emergencies—has been engaged for cooling purposes just 3% of the time. Temperature control has been maintained consistently, even in ambient temperatures exceeding 40°C.

Environmental impact is measurable: 102 tonnes of CO2 saved in the first year of fleet operation. For a 16-trailer deployment, that translates to approximately 6.4 tonnes per trailer annually—a figure that scales linearly as fleets expand.

Feroz Koor, Woolworths Holdings Group Head of Sustainability, has positioned this initiative within the company’s broader Vision 2025+ goal of achieving net-zero carbon emissions by 2040. The AxlePower deployment demonstrates that sustainability targets can be pursued without compromising operational reliability.

For operators considering similar deployments, the Woolworths experience validates several key points. First, the technology works on South Africa’s most demanding long-haul route. Second, performance is consistent across seasonal temperature variations. Third, the 97% electric operation rate translates to near-complete elimination of refrigeration fuel costs.

Shoprite Group: Solar Fleet at National Scale

Africa’s largest grocery retailer has pursued solar-powered refrigeration more aggressively than any other operator on the continent. The numbers reflect genuine scale: 903 trucks, 1,360 trailers, with approximately 90% of the trailer fleet now incorporating solar systems.

The financial case is decisive. Annual diesel savings exceed R60 million across the fleet. Per-trailer savings average 4.8 litres of diesel daily. Return on investment is achieved in 1.4 years from installation—and that calculation considers only direct fuel savings, not maintenance reductions or carbon-related benefits.

Shoprite’s journey began in 2017, making it an eight-year case study in solar refrigeration deployment. The technology has moved from experimental to standard specification—every new vehicle now includes solar capability as baseline equipment.

The retailer has also pioneered related technologies. Its first heavy-duty battery-electric truck—a Scania unit with solar panels and fully electric cooling—entered service in late 2022 for local Cape Town deliveries. The fleet includes over 100 Euro 5 compliant trucks, representing the most fuel-efficient diesel technology available while the transition to electric continues.

For operators evaluating solar-hybrid systems, Shoprite’s experience demonstrates that the technology scales effectively. What works on one trailer works on a thousand. The 1.4-year ROI provides a clear financial framework for investment decisions. And the progression from pilot to standard specification shows a viable pathway for fleet-wide adoption.

Vector Logistics: Full Electric Cold Chain

Vector Logistics’ March 2025 deployment represents South Africa’s first fully integrated electric cold chain solution. The two Volvo FH 6×4 battery-electric tractors, paired with e-axle trailers and electrified refrigeration, operate as genuinely net-zero units from bumper to bumper.

The technical specifications reflect current state-of-the-art: three electric motors producing 665 horsepower and 2,400Nm of torque, powered by six batteries with 540kWh total capacity. Range sits between 200 and 300 kilometres per charge, depending on load and conditions.

Vector invested in high-speed DC charging stations at depots in Gauteng and Cape Town, enabling rapid turnaround between delivery runs. The charging infrastructure is solar-powered, meaning the entire energy chain—from generation through delivery—can operate on renewable sources.

The company’s sustainability targets are ambitious: a minimum 42% reduction in greenhouse gas emissions by the end of 2030. The electric truck deployment is one component of a broader strategy that includes expanding solar installations at facilities and transitioning additional fleet segments as technology and economics permit.

Annelie Govender, Vector’s Chief Human Resources Officer and ESG Lead, has framed the initiative in competitive terms: “Achieving carbon neutrality is not just a competitive advantage—it lays the foundation for a sustainable and resilient logistics industry.”

For the broader industry, Vector’s deployment proves that fully electric cold chain operations are technically viable in South Africa. The vehicles have integrated seamlessly into existing fleet operations. Driver training has been completed successfully. And the 200-300km range is proving adequate for regional distribution requirements.

Cryogenic Operations: Proven but Infrastructure-Constrained

While specific operator names are less publicly documented, cryogenic refrigeration has a substantial footprint in South African cold chain operations. A leading supermarket retailer operates approximately 300 liquid nitrogen trailer units for deep-frozen distribution nationally.

The technology delivers zero on-road emissions with superior temperature control for ultra-low temperature applications. The absence of a diesel engine means significantly reduced maintenance requirements and silent operation—valuable for early-morning or late-night deliveries in residential areas.

The constraint remains infrastructure. Industry participants consistently identify the lack of bulk nitrogen depots in strategic inland locations as the primary barrier to expanded cryogenic adoption. Establishing facilities in locations like Bloemfontein would enable long-haul cryogenic operations that currently aren’t viable due to refuelling limitations.

For operators with appropriate route profiles—particularly those serving deep-frozen applications on routes with nitrogen availability—cryogenic systems offer a proven, commercially deployed zero-emission solution.

Grid Stability: The Game-Changer for Electric Fleet Planning

Any discussion of electric vehicles in South Africa must address electricity supply. The load shedding crisis that peaked in 2022-2023 created legitimate concerns about the viability of electric transport. Those concerns require reassessment in light of 2024-2025 developments.

The Transformation in Numbers

The contrast between recent years is stark. In 2023, South Africa experienced 335 days with load shedding, with 16.6 million megawatt-hours shed from the grid. The economy suffered, businesses invested heavily in backup generation, and electric vehicle adoption seemed impractical.

By 2024, load shedding days dropped to 83. Through 2025, the improvement accelerated dramatically—only 26 hours of load shedding occurred, all concentrated in April and May. As of early 2026, South Africa had recorded 231 consecutive days without load shedding.

The Energy Availability Factor, which measures the percentage of generation capacity actually available, has improved consistently. Eskom’s Generation Recovery Plan has delivered measurable results through better maintenance practices, reduced unplanned outages, and the return to service of previously offline units.

Implications for Cold Chain Operations

For operators considering electric fleet investments, grid stability changes the calculus fundamentally.

Depot charging becomes reliable and plannable. Electric trucks returning to home base can charge overnight with reasonable confidence that power will be available. The unpredictability that made electric operations risky in 2022-2023 has substantially diminished.

Solar installations at facilities deliver consistent returns. Warehouses and distribution centres investing in rooftop solar can expect reliable generation during daylight hours, reducing both grid dependence and operating costs. The business case for renewable energy at cold storage facilities has strengthened considerably.

Battery backup sizing can be optimised. Rather than over-specifying backup systems to cover extended outage scenarios, operators can design systems for realistic contingencies. This reduces capital costs and improves overall system economics.

The Distinction: Load Shedding vs Load Reduction

A nuance often overlooked in grid discussions is the difference between load shedding and load reduction. Load shedding results from generation shortfalls at the national level. Load reduction occurs when local distribution infrastructure is overloaded, often due to illegal connections, cable theft, or aging equipment.

Load reduction continues to affect certain areas, particularly peri-urban communities and informal settlements. The implications for cold chain operators are geographic—depot location matters. Facilities in areas with reliable distribution infrastructure can plan electric operations with confidence. Those in affected areas may need additional contingency measures.

Eskom has committed to reducing load reduction by 15-20% by March 2026 and eliminating it within 18 months through infrastructure upgrades and formalisation of illegal connections. Progress on this commitment will further improve the environment for electric fleet operations.

Planning with Confidence

Eric Parry, Volvo Trucks South Africa’s Sustainable Solutions Manager, summarises the current situation pragmatically: “It is all down to planning. Operators will have the necessary tools to plan their charging options according to their workload and routes.”

Electric trucks in South Africa are primarily suited for regional distribution customers who return to a home base during their operating day. This is precisely where charging makes practical sense. Public charging infrastructure, while developing, is less critical for commercial operations than for passenger vehicles.

Having control over dedicated charging infrastructure allows operators to manage energy costs with certainty—a significant advantage over fluctuating diesel prices. Combined with on-site solar generation, operators can insulate themselves from both grid instability and fuel price volatility.

The Business Case: Costs, Incentives, and Return on Investment

Zero-emission technology delivers environmental benefits, but commercial adoption depends on economics. The business case has evolved substantially over recent years.

Current Cost Realities

Electric trucks carry higher capital costs than diesel equivalents. The purchase price difference is significant—exact figures vary by configuration, but the premium is substantial enough to require careful financial analysis.

Import duties compound the challenge. Electric trucks attract the same duty rates as diesel vehicles, but because the base price is higher, the absolute duty amount is greater. This regulatory artefact disadvantages electric technology despite its environmental benefits.

Weight and dimensions present practical complications. Battery packs add weight, reducing payload capacity. The batteries also extend wheelbase length—up to 1.1 metres longer than diesel equivalents in some configurations. Combined with standard trailers, the overall vehicle combination may exceed legal length limits. The Department of Transport is engaged on regulatory updates to accommodate new-energy vehicles, but current rules create operational constraints.

Despite these challenges, total cost of ownership increasingly favours zero-emission technology. Fuel savings are substantial and predictable. Maintenance costs drop significantly without diesel engines and their associated systems. And the trajectory of battery prices suggests purchase cost parity within the planning horizon.

Tax Incentives from March 2026

The South African government has introduced significant incentives for electric and hydrogen vehicle production, effective from March 2026. Manufacturers investing in production facilities can claim a 150% tax deduction on qualifying investments—meaning R100 invested yields R150 in tax deductions.

The incentive applies for a 10-year window, covering assets brought into use from 1 March 2026 through 28 February 2036. National Treasury estimates the tax cost at R500 million for the 2026/27 fiscal year, indicating substantial expected uptake.

For fleet operators, the manufacturing incentive has indirect benefits. Increased local production should improve availability and potentially reduce costs over time. Direct benefits flow from the existing Section 12B incentive for solar installations—the 125% deduction that makes solar-hybrid retrofits financially attractive.

Anti-abuse provisions require operators to maintain qualifying assets for at least five years or face partial recoupment of tax benefits. This aligns with typical fleet replacement cycles and shouldn’t constrain normal operations.

Operational Cost Savings

The direct savings from zero-emission technology are substantial and well-documented.

Solar-hybrid systems deliver ROI in approximately 1.4 years based on diesel savings alone. At 4.8 litres saved per trailer per day, operators running 250 days annually save roughly 1,200 litres per trailer per year. At current diesel prices, that’s material savings before considering maintenance reductions.

AxlePower systems eliminate refrigeration fuel costs almost entirely on long-haul routes. The 97% electric operation rate observed in Woolworths deployments means diesel costs approach zero for temperature control. Maintenance savings add further value.

Full electric trucks eliminate both traction and refrigeration fuel costs. Operating cost per kilometre drops dramatically compared to diesel, though the higher capital cost requires sufficient annual mileage to achieve payback within acceptable timeframes.

Hidden Value: Market Access and Financing

Beyond direct cost savings, zero-emission technology unlocks strategic value that’s harder to quantify but increasingly important.

Major customers are implementing supply chain sustainability requirements. Retailers, food service companies, and pharmaceutical distributors face their own carbon reduction targets and are extending those expectations to logistics providers. Operators with zero-emission capability can access contracts unavailable to diesel-only competitors.

Sustainability-linked financing is expanding. Shoprite secured R3.5 billion in sustainability-linked loans to support environmental initiatives including fleet upgrades. Operators demonstrating credible decarbonisation pathways can access preferential financing terms.

Urban access rules are evolving globally, with low-emission zones restricting diesel vehicle access in metropolitan areas. While South Africa hasn’t implemented such zones, the trajectory is clear. Operators investing in zero-emission technology today will be positioned for regulatory changes that may emerge by 2030.

Night delivery capability improves with electric and solar-hybrid systems. Quieter operation enables deliveries during off-peak hours, reducing urban congestion and improving route efficiency. Retailers increasingly value this flexibility.

Operational Considerations: What South African Conditions Demand

Generic guidance on electric vehicles often fails to account for conditions specific to South African operations. Effective planning requires understanding local factors.

Altitude Effects

Johannesburg sits at approximately 1,750 metres above sea level. This altitude affects both battery performance and refrigeration system operation in ways that sea-level testing may not reveal.

Battery thermal management becomes more critical at altitude. Thinner air provides less cooling, potentially affecting charging rates and battery longevity. Systems designed for European or coastal conditions may require adaptation for Highveld operations.

Refrigeration compressors must be appropriately derated for altitude operation. A system specified for sea-level performance may underperform at 1,750 metres. This applies to both conventional and electric refrigeration systems.

AxlePower technology has proven its performance on the N1 corridor, which includes significant altitude changes between Johannesburg and Cape Town. This real-world validation across altitude variations provides confidence for operators on similar routes.

High Ambient Temperatures

Summer temperatures in parts of South Africa regularly exceed 40°C. Urban heat islands—where pavement, buildings, and traffic generate additional warmth—can add 8-11°C to effective ambient temperature in distribution environments.

Zero-emission refrigeration systems must maintain performance under these conditions. The AxlePower deployment has validated operation “in ambient temperatures exceeding 40°C” with “constant cooling and uninterrupted airflow.” This real-world performance data is more valuable than laboratory specifications.

Solar panel efficiency decreases at high temperatures, typically dropping approximately 0.4% for each degree above 25°C. Panel specifications should account for actual operating temperatures, not standard test conditions. System designers should factor in efficiency degradation when sizing solar installations.

Battery systems also require thermal management in hot conditions. Electric trucks operating in high-temperature environments need effective cooling systems to maintain battery performance and longevity.

Multi-Drop Efficiency

Urban distribution typically involves multiple stops per route—loading at a distribution centre, then delivering to numerous retail locations, restaurants, or other endpoints. This stop-start pattern affects technology selection.

Electric motors suit stop-start driving better than diesel engines. Regenerative braking captures energy during deceleration, partially recharging batteries with each stop. There’s no idling fuel consumption while stationary. Acceleration is smooth and efficient.

Solar panels charge continuously during loading and unloading stops. A 30-minute delivery stop generates meaningful energy input to support refrigeration. This continuous charging during operational pauses differentiates solar-hybrid from diesel systems that consume fuel regardless of motion.

Range requirements for multi-drop urban routes are typically well within electric truck capabilities. A vehicle completing 15-20 stops across 150 kilometres is comfortably served by 200-300km battery range, with capacity to spare.

Charging Infrastructure

For commercial electric trucks, depot charging is the primary solution. Unlike passenger vehicles that might rely on public charging networks, commercial operations can install dedicated infrastructure at home bases.

Vector Logistics invested in high-speed DC charging stations at depots in Gauteng and Cape Town. This approach provides reliable, controlled charging with known energy costs. Overnight charging during off-peak hours can reduce electricity expenses.

Solar-powered charging reduces grid dependence entirely. Distribution centres with rooftop solar can charge electric trucks using self-generated renewable energy, creating a fully sustainable operation from generation through delivery.

Public fast-charging networks for commercial vehicles remain limited in South Africa. This isn’t a significant barrier for regional distribution operations returning to depot daily, but it does constrain long-haul electric applications until infrastructure develops further.

Weight and Length Constraints

Current South African regulations weren’t designed with electric vehicles in mind. Battery weight and the additional wheelbase length required to accommodate battery packs create compliance challenges.

Electric truck combinations may exceed legal length limits when paired with standard trailers. The Department of Transport is engaged on potential regulatory updates to accommodate new-energy vehicles, but resolution timelines are uncertain.

Payload capacity is reduced by battery weight. Operators must factor this into route planning and load optimisation. For some applications, the payload reduction may be operationally insignificant; for others, it requires adjusted approaches.

Route planning should optimise load factors to account for any payload constraints. Software tools that maximise utilisation within weight limits become more valuable as fleets transition to electric.

Driver Training

Electric truck operation requires skills that differ from diesel vehicle operation. Regenerative braking behaves differently from conventional brakes. Range management requires awareness of battery status and charging opportunities. Charging procedures must be understood and followed correctly.

Equipment manufacturers are providing specialised training for South African deployments. Volvo’s driver trainers have worked with Vector Logistics operators, with further training planned to refine skills over time.

Driver acceptance has been positive. The quieter, smoother operation of electric trucks is generally preferred once drivers gain familiarity. The absence of vibration and reduced noise creates a more comfortable working environment.

Training investment should be factored into transition planning. Operators can’t simply swap electric trucks into existing operations without preparing drivers for the differences.

Technology Roadmap: What’s Coming by 2030

Current technology represents the beginning of the zero-emission transition, not its endpoint. Understanding the development trajectory helps operators plan investments with appropriate time horizons.

Long-Range Electric Trucks

Battery technology continues advancing rapidly. Over the past six years, battery capacity has increased 40-45% while physical size has decreased. This trajectory shows no signs of slowing.

Volvo has announced long-range electric trucks launching in Europe during 2026, designed for applications currently served by diesel. While configured for European conditions, innovations from these platforms will filter into configurations suitable for South African operations.

Range limitations that constrain current electric trucks to regional distribution will ease over time. By 2030, electric trucks capable of serving longer routes should be available, expanding the applications where electric technology is viable.

Hydrogen-Powered Transport

Green hydrogen represents a parallel pathway to zero-emission transport, particularly for applications where battery-electric solutions face limitations.

South Africa has significant green hydrogen ambitions. The Hydrogen Valley initiative links Limpopo, Gauteng, and Mpumalanga in an integrated hydrogen ecosystem. Twenty-four green hydrogen projects have been designated as Strategic Integrated Projects. The Coega Green Ammonia Project in the Eastern Cape represents a $5.7 billion investment in hydrogen-derived fuel production.

For heavy transport, hydrogen fuel cell technology offers advantages in range and refuelling time compared to battery-electric. A hydrogen truck can refuel in minutes rather than hours, making it suitable for operations where extended charging windows aren’t available.

Government has secured €23 million in German grant funding via KfW Development Bank to support green hydrogen projects. The Just Energy Transition Green Hydrogen Programme Management Office coordinates implementation across multiple initiatives.

By 2030, hydrogen-powered freight transport should move from pilot projects to commercial availability, providing another zero-emission option for cold chain operators.

Infrastructure Development

The infrastructure supporting zero-emission transport will expand substantially over the coming years.

Electric charging corridors along major freight routes are under development. As electric truck adoption increases, charging infrastructure will follow—creating a virtuous cycle of capability expansion.

Liquid nitrogen bulk depot networks could unlock broader cryogenic refrigeration adoption. Industry participants have identified specific locations where infrastructure investment would enable new routes. Commercial interest may drive this development as cryogenic technology proves its value.

Solar and battery installations at distribution centres will become standard rather than exceptional. The combination of grid uncertainty, favourable economics, and sustainability requirements makes on-site renewable generation increasingly attractive.

Regulatory Evolution

Regulations will adapt to accommodate zero-emission technology and potentially mandate its adoption.

Vehicle length and weight regulations are under review to address electric drivetrain requirements. Resolution would remove a significant barrier to electric truck adoption.

Urban emission zones may emerge in South African metropolitan areas, following patterns established in Europe and elsewhere. Operators with zero-emission capability would have access advantages if such zones are implemented.

Carbon reporting requirements continue expanding. Companies face increasing pressure to measure, disclose, and reduce supply chain emissions. Zero-emission transport capability simplifies compliance with these evolving requirements.

Cost Trajectories

The economics of zero-emission technology will improve over the planning horizon.

Battery prices continue declining as manufacturing scales globally. Electric truck purchase costs should approach diesel equivalents during the second half of the decade.

Solar panel efficiency continues improving while costs decrease. The already-attractive economics of solar-hybrid systems will strengthen further.

As production volumes increase and supply chains mature, zero-emission technology will transition from premium option to cost-competitive alternative—and eventually to lower-cost choice for appropriate applications.

Action Framework: Planning Your Transition

For operators ready to act, a structured approach reduces risk while capturing available benefits.

Assessment Phase: Now

Begin with comprehensive analysis of current operations:

• Fleet audit. Document current fleet age, replacement schedules, and remaining useful life for each vehicle. Identify units approaching replacement that could transition to zero-emission technology.
• Route profiling. Map typical routes by distance, number of stops, depot return frequency, and overnight parking locations. This analysis identifies which operations suit which technologies.
• Cost baseline. Calculate current fuel and maintenance costs per vehicle and per kilometre. This baseline enables accurate comparison with zero-emission alternatives.
• Emission inventory. Quantify current fleet emissions to establish a reference point for reduction targets and sustainability reporting.
• High-priority identification. Identify vehicles with the highest fuel costs, maintenance expenses, or emission intensity. These are prime candidates for early transition.

Pilot Phase: 2025-2026

Start with proven, lower-risk technologies before committing to full fleet transition:

• Solar-hybrid retrofits. Begin with solar-hybrid systems on existing trailers. The 1.4-year ROI and retrofit capability make this an accessible starting point with proven returns.
• AxlePower evaluation. For operators with suitable long-haul routes, engage with Thermo King to assess AxlePower suitability. The Woolworths deployment provides a reference case for similar operations.
• Supplier engagement. Develop relationships with Thermo King, Transfrig, NextDrive, and other technology providers. Understanding available solutions and support capabilities informs larger decisions.
• Performance tracking. Implement systems to capture real-world performance data from pilot deployments. Actual fuel savings, maintenance experience, and operational impacts should drive subsequent decisions.
• Driver feedback. Engage drivers in pilot programs and capture their experience. Driver acceptance is essential for successful fleet-wide adoption.

Scale Phase: 2027-2029

With pilot experience informing decisions, expand zero-emission deployment:

• Fleet replacement alignment. Replace aging diesel units with zero-emission alternatives as they reach end of life. Aligning technology transition with natural replacement cycles optimises capital efficiency.
• Infrastructure investment. Install depot charging infrastructure for electric trucks. Expand solar generation capacity at facilities. Build the foundation for scaled electric operations.
• Training programs. Develop comprehensive driver training for zero-emission vehicle operation. Build internal expertise rather than depending entirely on manufacturer support.
• Incentive capture. Structure investments to maximise available tax incentives. The 150% deduction for qualifying investments from March 2026 represents significant value.
• Supply chain engagement. Communicate transition plans to customers and suppliers. Sustainability-conscious partners may provide preference or support for operators demonstrating commitment.

Optimisation Phase: 2030 and Beyond

With substantial zero-emission capability in place, focus on refinement:

• Full fleet transition. Complete conversion to zero-emission technology for all suitable applications. Diesel may remain appropriate for specific use cases, but should become the exception rather than the rule.
• Renewable integration. Connect fleet charging with renewable energy supply, whether on-site solar or green power purchase agreements. Achieve genuine zero-emission operation from generation through delivery.
• Advanced optimisation. Implement sophisticated route and charging optimisation tools. Extract maximum efficiency from zero-emission fleet capabilities.
• Certification and reporting. Pursue relevant sustainability certifications. Develop robust emission reporting to meet customer and regulatory requirements.

Technology Selection Guide

Matching technology to operation type improves outcomes:

• Long-haul national routes suit AxlePower or solar-hybrid systems. These technologies have no range limitations and proven performance on extended routes.
• Regional distribution returning to depot daily suits full electric trucks combined with AxlePower trailers. Overnight charging provides adequate range for daily operations.
• Urban multi-drop operations suit solar-hybrid or full electric solutions. Stop-start patterns favour regenerative braking and solar charging during delivery stops.
• Deep-frozen applications suit cryogenic systems where nitrogen infrastructure exists. Superior temperature performance justifies any additional complexity.
• Mixed fleets benefit from a hybrid approach. Match technology to route profile rather than standardising across diverse operations.

Conclusion

Zero-emission refrigerated transport has moved from aspiration to operation in South Africa. The technology works. The economics are viable for appropriate applications. The grid has stabilised enough to support electric fleet planning.

The 2030 horizon provides a realistic timeframe for meaningful transition. Fleet replacement cycles align with this planning period. Technology will continue improving. Infrastructure will expand. Regulatory frameworks will adapt.

Early movers are capturing competitive advantage today. Woolworths, Shoprite, and Vector Logistics aren’t pursuing zero-emission technology for public relations value alone—they’re achieving genuine operational benefits and positioning for a future where sustainability is expected rather than exceptional.

For operators planning fleet decisions over the coming years, the path forward is increasingly clear. Start with solar-hybrid retrofits to capture immediate savings and build experience. Evaluate AxlePower for long-haul applications where the technology has proven its value. Consider full electric for regional distribution as the economics and infrastructure mature.

The cold chain that serves South Africa in 2030 will look substantially different from today. Operators who begin their transition now will be prepared for that future. Those who wait may find themselves at a disadvantage—facing both regulatory pressure and competitive displacement from sustainability-focused customers.

The question is no longer whether zero-emission refrigerated transport works in South Africa. It does. The question is how quickly you’ll move to capture its benefits.
