San Mateo County Transit District (SamTrans) has awarded Fastech and Bosch Rexroth a contract to build a hydrogen refuelling station for up to 175 fuel cell buses in California. The facility will feature the first commercial deployment of Bosch Rexroth’s CryoPump technology and is expected to become the world’s largest bus-focused hydrogen station.Image: SamTransThe project is designed to support a fleet of up to 175 fuel cell electric buses. The station will feature four dispensers capable of fuelling multiple vehicles simultaneously and will be able to deliver up to 3.5 tonnes of hydrogen per day. Bosch Rexroth states that its technology can dispense up to 1,200 kilograms of hydrogen per hour, providing capacity for future fleet expansion.According to the partners, the facility is expected to become the largest hydrogen refuelling station dedicated to transit bus operations worldwide. The station will serve as the primary hydrogen hub for SamTrans, which operates 74 fixed bus routes and an on-demand transit service.A key element of the project is the first commercial deployment of Bosch Rexroth’s CryoPump hydrogen refuelling technology. The company says the system eliminates the need for buffer gas storage and complex mechanical valve manifolds. It is also designed to significantly reduce hydrogen losses associated with boil-off and venting during hydrogen transfer and vehicle refuelling operations. Fastech will be responsible for integrating the refuelling infrastructure and delivering the overall station.“This project demonstrates how hydrogen can be deployed at scale to support reliable, zero-emission public transportation,” said Dan McGill, President of Fadtech. “By combining Bosch Rexroth’s advanced hydrogen technologies with Fastech’s fueling infrastructure expertise, we are helping to establish a new benchmark for sustainable transit infrastructure worldwide.”fastechus.com
