The Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE) awarded a $2,520,955 Cooperative Agreement under the Renewable Energy Research and Development program (CFDA 81.087) to Komatsu America Corp. The project will research and prototype an onboard high-capacity liquid hydrogen (LH2) storage system, including balance-of-plant (BOP) components, for ultra-class mining trucks. The goal is to reduce the time-between-refueling of fuel cell powered vehicles, increase their competitiveness against diesel-powered machines, and accelerate the adoption of fuel cell vehicles in the mining industry. Key objectives include maximizing tank capacity, minimizing boil-off losses, optimizing dormancy, and ensuring durability and safety in harsh mining conditions. The project will integrate a 200+ kg LH2 storage vessel into a Komatsu 930-E haul truck and work to address critical challenges around fuel management processes. The award period runs from August 1, 2024, through May 31, 2025.
