Ocado has begun using zero-emission refrigeration units across its flagship double-deck trailer fleet as part of efforts to cut emissions and reduce costs.
The online grocer confirmed that Sunswap’s Endurance units — powered by batteries and solar panels — are now fitted to its double-deck trailers, keeping fresh and frozen produce chilled without using diesel.
Each Endurance unit eliminates diesel consumption completely, cutting up to 20.5 tonnes of CO2 per year and reducing operating costs by as much as 81% compared with traditional refrigeration. Integrated solar panels on trailer roofs provide supplementary energy, reducing reliance on grid charging and extending operational range.
Sunswap said the units can deliver up to 24 hours of frozen operation or two months of chilled operation from a single charge, ensuring reliable temperature control without the compromises often associated with sustainable alternatives.
The deployment, which began in July, supports Ocado’s target of achieving net-zero emissions across its value chain by 2040. The retailer’s commitments, validated by the Science-Based Targets initiative (SBTi), include cutting Scope 1 and 2 emissions by 42% by 2030.
Michael Lowe, chief executive of Sunswap, said: “We’re delighted that Ocado has chosen Sunswap’s zero-emission refrigeration technology. This deployment demonstrates that electric refrigeration can meet the operational requirements of major grocery retailers while supporting their sustainability goals.”
Ocado’s move reflects a broader trend in the logistics and retail sectors towards cleaner transport technologies, with retailers under increasing pressure to decarbonise operations and demonstrate progress towards net-zero pledges.
