Thermal Energy Service Solutions Pvt. Ltd. (TESSOL) has developed a fuel-free reefer system called PLUGnCHILL that uses thermal energy storage to power refrigerated trucks. The system works by plugging the reefer truck into the grid for 4-6 hours to charge a phase change material storage system. This allows the truck to then make deliveries over multiple days without using any fuel. TESSOL's system provides cost savings over diesel reefers of 65-73% and reduces carbon emissions. Case studies demonstrated the system maintained temperature during deliveries even with long door opening times.
