Bosch unveils turnkey CryoPump hydrogen refueling stations

At the Hydrogen Technology World Expo 2026, Bosch Rexroth and Bosch Manufacturing Solutions introduced a turnkey hydrogen refueling solution for heavy-duty commercial vehicles. Centered around a novel electrohydraulic CryoPump module, the system can refuel up to eight heavy-duty trucks per hour, enabling an average driving range of 1,000 kilometers per vehicle. By delivering both subcooled liquid hydrogen (sLH2) and high-pressure gaseous hydrogen simultaneously, the platform aims to make hydrogen fueling competitive with diesel operations in terms of both refueling time and range.

Lean architecture cuts capital expenditure
Traditional hydrogen refueling stations require extensive high-pressure storage tanks and energy-intensive chiller systems to dispense gas. The Bosch turnkey solution circumvents this by integrating the central pump, hydraulic, and control functions into a single compact CryoPump unit. With this architecture, developers only need to install a liquid hydrogen tank, a vaporizer, and a dispenser on-site. By dispensing fuel directly to the vehicle and eliminating the need for intermediary high-pressure storage and cooling modules, the station drastically reduces its physical footprint and cuts overall capital investment costs by up to 50 percent.

Field-proven reliability and global expansion
The CryoPump technology has been validated in continuous commercial operation since October 2025 at the Port of Oakland, California. In this deployment, minimal boil-off losses and extended maintenance cycles have reduced station operating costs by up to 70 percent. Building on this success, Bosch Rexroth is partnering with infrastructure developer Fastech to construct a new station in 2027 for SamTrans in the San Francisco Bay Area, which will service a fleet of 175 hydrogen buses. Bosch Manufacturing Solutions is now bringing this turnkey engineering approach to the European market, where subcooled liquid hydrogen is rapidly establishing itself as the preferred standard for heavy-duty transport.

Additional Context: The shift to subcooled liquid hydrogen (sLH2)
This section details technical specifications and competitive benchmarking not included in the original product announcement.

For heavy-duty trucks, traditional 700-bar compressed hydrogen gas (CHG70) poses significant volumetric packaging challenges, achieving a maximum density of roughly 40 kg/m³. By contrast, subcooled liquid hydrogen (sLH2)—a standard heavily championed in Europe by commercial OEMs like Daimler Truck—achieves a significantly higher density of up to 62 kg/m³ at a relatively low pressure of 16 bar. This allows trucks to utilize lighter, insulated stainless-steel tanks rather than heavy, carbon-fiber-reinforced Type IV pressure vessels, thereby increasing the overall payload capacity of the vehicle. Furthermore, sLH2 refueling protocols are vastly simpler; they do not require complex data communication between the truck and the station to manage thermal limits, nor do they rely on active gas-return lines. The Bosch CryoPump exploits these thermodynamic advantages to achieve diesel-equivalent fill times, utilizing a highly efficient servohydraulic displacement control system that avoids the inherent energy losses associated with standard throttle control valves.
