Gist in zero-carbon refrigeration trial with Sunswap

Gist has partnered with an engineering firm to trial a zero-emission, solar and battery powered transport refrigeration unit (TRU) within its temperature controlled fleet.

Start-up firm Sunswap has developed the technology, which it said relies on energy prediction software, adaptive battery capacity and a solar energy recovery system to decarbonise refrigerated trailers in the cold chain.

Depending on weather conditions, Sunswap’s solar panels on the Endurance TRU can provide 65-80% of the charge needed throughout the year to operate the refrigeration unit. It added that the Endurance is able to operate at 10% of the running costs in comparison to a diesel-powered TRU.

The trial is operating from Gist’s Chesterfield depot and forms part of the logistics firm’s commitment to explore innovative solutions to reduce carbon emissions.

Kate Brown, Gist communications and sustainability director, said: “We are always looking to trial new innovations, such as Sunswap’s TRU, as part of our commitment to creating a greener, more efficient distribution fleet.”

Michael Lowe, Sunswap chief executive, said: “With diesel now more expensive for TRUs and emissions targets getting closer, the logistics sector has responded fantastically and is actively looking for innovative solutions to achieve net zero.”
