Peterborough, UK: Sunswap has successfully completed a trial of its battery and solar-powered transport refrigeration technology with temperature-controlled operator JS Davidson.
JS Davidson is aiming to reach net zero by the end of 2025 at its Peterborough site. The trial, which took place over two weeks, showcased the capabilities of the Sunswap Endurance refrigeration unit running frozen delivery cycles.
JS Davidson integrated Sunswap’s Endurance unit into its fleet, treating it as “just another fridge in their operation”. JS Davidson’s transport team said there were no disruptions, highlighting Endurance’s ability to function as a direct replacement for conventional diesel-powered units.
The data collected during the trial demonstrates JS Davidson could remove 519 tonnes of CO2 and 5 tonnes of NOx over the lifetime of five units, taking substantial steps towards creating a cleaner cold chain.
The trailer-top solar panels collected free energy during the trial, reducing reliance on grid charging. Simulations based on 10 years of weather data suggest that solar energy could contribute up to 37% of the unit’s energy needs during spring months. This highlights the potential for solar power to provide benefits such as extending range, reducing operation costs and reducing the cost and weight of batteries, says Sunswap.
The adoption of five Sunswap Endurance units in JS Davidson’s fleet could result in a 70% in operational expense compared to diesel, says Sunswap.
John Davidson, managing director of JS Davidson, said: “Environmental considerations are high on the JS Davidson agenda and are taking an increasing number of measures to help us meet our net zero target.
“The Endurance unit not only met but exceeded our expectations in terms of performance and reliability. We are thrilled to be at the forefront of trialling sustainable refrigeration technology that aligns with our commitment to reducing our environmental impact.”
Sunswap says that the successful trial “underscores the immense potential for battery and solar-powered refrigeration to decarbonise the temperature-controlled logistics industry”. By harnessing grid electricity and the power of renewable solar energy, companies like JS Davidson can significantly reduce their carbon footprint and operational costs while maintaining the highest standards for the transport of temperature-controlled goods, says Sunswap.
Alastair Gough, head of business development at Sunswap said: “Our partnership with JS Davidson is a testament to the viability and effectiveness of our battery and solar-powered refrigeration technology. The Endurance unit’s performance during this trial demonstrates that sustainable solutions can seamlessly integrate into existing logistics operations, delivering tangible benefits for both businesses and the environment.”
