Our solutions for the hydrogen industry

CryoPump Station with integrated cryogenic pump

The CryoPump Station revolutionizes hydrogen infrastructure with innovative technology tailored to the challenges of hydrogen mobility. Our cryopump technology enables economical hydrogen refueling, reduces operating costs by up to 70 % and reduces the space requirements of refueling stations, facilitating integration into existing structures. It was developed with Firstelement Fuel, the leading operator of hydrogen refueling stations.

Your Benefits:

• Reduced load cycles and eliminated dead volume increase efficiency up to 95%.
• With 4000 operating hours before maintenance, it significantly outperforms conventional systems.
• Minimized boil-off losses thanks to optimized thermal insulation.
• Direct vehicle refueling possible without additional high-pressure storage tanks; this reduces complexity and costs.
• With a pumping capacity of 600 kg/h, it is five times more powerful than competing technologies.
• Turnkey construction and space-saving design (<11 m²) enables use in urban areas.
• Sound pressure level below 65 dB(A) improves environmental compatibility.
• Conveying of liquid and gaseous hydrogen for new storage concepts offers flexibility for the future.

Compact drives for small hydrogen systems

For smaller daily production quantities in the range of up to 10 kg H2/h, the Bosch Rexroth drive portfolio includes highly efficient complete systems in the form of servohydraulic axes (SHA). These particularly compact solutions concentrate a variable-speed drive comprising a servo motor, hydraulic pump, control block, synchronous cylinder and minimal oil volume in a very small space. Customer-specific compressors are mounted on the cylinder itself.

The SHA can be used to compress not only hydrogen, but other gases too. The SHA is already well established in the market. With its extremely compact size, it is particularly suitable for retrofitting in modular and highly mobile systems. Thanks to displacement control, our SHAs are very energy efficient. Another strength lies in their quick installation and commissioning. Firstly, they can be installed without pipework. Secondly, the pre-configured SHA is a “plug & produce” solution and thus requires no programming work. Instead, it is simply parameterized on site and is ready for immediate use.

New cryopump: Refueling 100 kg hydrogen in 10 minutes

Bosch Rexroth developed the new electrohydraulically driven cryopump in collaboration with FirstElement Fuel, the market leader for the commercial operation of hydrogen filling stations in the USA. With a connection rating of 280 kW, it compresses liquid hydrogen to 875 bar for the direct refueling of heavy trucks. The aim is to refuel vehicles with 100 kg of hydrogen within 10 minutes. With direct refueling, there is no need for temporary storage tanks at filling stations.

Your Benefits:

• Very high availability and robustness
• Low loss of hydrogen
• Low operating and energy costs due to highly efficient drive and pump technology
• Elimination of costly high-pressure intermediate storage tanks due to high pump volume flow and controllability
• Simplified integration into existing filling station concepts
