At Ocado Logistics, innovation and sustainability go hand in hand. As we continue to decarbonise our operations, we’re focused on deploying technologies that deliver real-world performance today while supporting our long-term net-zero ambitions. That’s why we’re pleased to be operating Sunswap Endurance, the electric, battery- and solar-powered transport refrigeration system, across our flagship double-deck trailer fleet.
Developed by British engineering company Sunswap, Endurance is now keeping our fresh and frozen groceries at precise temperatures using purpose-built electric refrigeration. By removing diesel from the equation entirely, the technology delivers true zero tailpipe emissions without compromising on reliability or operational capability.
Each Endurance unit saves an estimated 20.5 tonnes of CO₂ per year compared to traditional diesel refrigeration, while reducing operating costs by up to 81%. Integrated solar panels on the trailer roof provide additional free energy, helping to extend range and reduce the need for grid charging—an important advantage in busy, high-utilisation logistics environments.
From an operational perspective, Endurance has been designed to meet the demands of grocery logistics. A single charge can deliver up to 24hours of frozen operation or up to two months of chilled operation, ensuring consistent temperature control across a wide range of routes and duty cycles. This means our teams can rely on dependable performance while benefiting from a quieter, cleaner solution.
The deployment, which began in July 2025, supports our commitment to achieving net-zero emissions across our entire value chain by2040. This includes our Science Based Targets initiative (SBTi)-validated goals, such as a 42% reduction in Scope 1 and 2 emissions by 2030. Electrifying transport refrigeration is a key step in reducing emissions from our logistics operations and accelerating progress against these targets.
Partnerships with innovative UK businesses like Sunswap play a crucial role in helping us scale sustainable solutions across our fleet. By working together, we’re demonstrating that zero-emission technologies can deliver both environmental benefits and strong operational performance at scale.
We’ll continue to invest in and trial new technologies that help us build a more sustainable, resilient logistics network, supporting our customers, our partners and the communities we serve.
