The first 10 Sunswap Endurance units hit UK roads, proving that zero-emission refrigerated transport is here and it doesn’t require a drop of diesel. Each unit eliminates 89.5 tonnes of CO2 over its lifetime while cutting operating costs by 71%. Showing there is no need to choose between going green and staying competitive. The Challenge That Started It All DFDS’s "Moving to Green" strategy set ambitious targets: 75% reduction in land CO2e emissions intensity by 2030 and net zero by 2050. Clear goals and real deadlines. All of which required actual solutions. --- ## https://sunswap.co.uk/case-studies/tesco Tesco: Leading UK Retail's Transition to Zero-Emission Cooling The Breakthrough In February 2025, five Sunswap Endurance units began operating at Tesco's Peterborough depot, marking the first deployment of battery and solar-powered transport refrigeration by the UK's largest grocer. Tesco integrated zero-emission refrigeration directly into their operational fleet, handling the complex demands of retail cold chain delivery. The battery and solar-powered units now transport fresh produce, dairy, and frozen foods in separate compartments during single delivery runs – exactly the kind of triple temperature complexity that makes retail logistics demanding. The Challenge That Started It All Tesco faces ambitious sustainability commitments: carbon neutrality across their own operations by 2035 and net zero across their value chain by 2050. --- ## https://sunswap.co.uk/case-studies/bannister-transport Bannister Transport: The First Fully Electric Refrigerated Fleet The Breakthrough Bannister Transport is removing every single diesel refrigeration unit from their operations, creating the world’s first fully electric refrigerated trailer fleet. All 40 trailers. Zero diesel. Zero emissions. The countdown to removing the last diesel refrigeration unit from the Bannister fleet has now begun, with each new Sunswap delivery bringing the company closer to its sustainability goals. When complete, this fleet transformation will eliminate 1,760 tonnes of CO2 and 13,600 kg of harmful NOx pollutants over the lifetime of the units - equivalent to removing 419 cars from the road. This shows fleet electrification works at a commercial scale and operators are ready to adopt. --- ## https://sunswap.co.uk/case-studies/cranswick Cranswick: When Britain's Food Giant Chose Zero-Emission Over HVO Cranswick are one of Britain's largest farm-to-fork food producers, with over a billion in revenue and some seriously ambitious 2040 net zero goals. So when they needed to accelerate their path to those goals, they didn't just test Sunswap Endurance against regular diesel. Instead, they put us head-to-head against HVO (Hydrotreated Vegetable Oil) which is already considered one of the cleanest diesel alternatives. The results? Sunswap delivered 81% lower running costs and 43% total cost savings. While HVO reduces CO2 emissions, it doesn’t eliminate CO2 entirely, plus it still produces those harmful NOx and particulate matter emissions that mess with local air quality. Sunswap eliminated them entirely. Gone. Zero. --- ## https://sunswap.co.uk/case-studies/staples-vegetables Staples Vegetables: When Solar Power Conquered Summer's Toughest Test Staples Vegetables achieved what many thought impossible: 96% solar-powered refrigeration during Britain's hottest summer days. When temperatures hit 30°C and cooling demands peaked, their Sunswap Endurance units drew virtually all power directly from the sun - eliminating grid charging entirely. The Lincolnshire farming business is expected to cut transport refrigeration costs by 78% while maintaining farm-fresh quality from field to fork. Their first two units will eliminate 256 tonnes of CO2 over the next decade while proving that renewable energy can power intensive agricultural logistics year-round. The Initial Challenge British produce faces a critical test every summer, crops come straight from hot fields and need to be kept at cool temperature for transport. --- ## https://sunswap.co.uk/media-and-press Press & Media Kit - Sunswap Featured in Introduction to Sunswap Founded: 2020 Headquarters: Leatherhead, Surrey, UK Markets in operation: UK and Europe (more to be confirmed) Product: Endurance, a battery and solar-powered transport refrigeration unit Benefits to operators: Zero emissions and no more diesel Operational cost savings: Up to 81% Solar energy: Up to 80% free solar power across the year A better fridge - cloud-connected, state-of-the-art proactive diagnostics Find more about from ourcase studies with major companies.

Not just a greener one - a better one. While the industry was stuck with diesel, we started from scratch. Today, from our UK manufacturing facility and growing European operations, we're proving that building electric from day one doesn't just eliminate emissions - it delivers superior performance that operators actually want. Two companies have controlled transport refrigeration for decades, selling the same polluting diesel technology with minor updates. We're not updating the past - we have built what comes next: Intelligent connected transport refrigeration that delivers data, performance, and zero-emissions. --- ## https://sunswap.co.uk/contact Contact Sunswap | Get in Touch Transport Your Fleet Into the Future, Today Move beyond diesel with our proven electric transport refrigeration, trusted by leading UK and European transport operators and retailers.
