Innovative cryopumps from Bosch Rexroth optimize hydrogen infrastructure
Bosch Rexroth is presenting new pump stations for hydrogen filling stations at the Hannover Messe. By using liquid hydrogen, they increase transport capacity, reduce operating costs by up to 70% and thus enable economical refueling. The stations are technologically flexible and enable refueling with both liquid and gaseous hydrogen – depending on the requirements of different vehicle concepts. Bosch Rexroth is setting new standards for the hydrogen filling stations of the future.
Robustness and efficiency thanks to hydraulic drive
The Bosch Rexroth cryopumps developed in collaboration with FirstElement Fuel, the market leader for the commercial operation of liquid hydrogen filling stations in the USA, are based on an electro-hydraulic drive concept with an extended stroke length, which reduces load changes and minimizes wear. Compared to conventional crankshaft-based pumps, the technology increases efficiency to over 95% and extends maintenance intervals to over 4,000 hours. The two-stage pump technology also allows both liquid and gaseous hydrogen to be pumped. This enables flexible storage concepts.
Quiet and compact CryoPump stations for an efficient hydrogen infrastructure
The electro-hydraulic drive technology of the pump stations enables quiet and space-saving operation. With a footprint of less than 11 m² and a noise level of less than 65 dB(A), they are ideal for use in existing filling stations, even in residential areas. The pump stations are an important basis for the worldwide expansion of an efficient hydrogen infrastructure.
Lower hydrogen prices and faster amortization for operators
Thanks to their high efficiency and minimal boil-off losses, CryoPump stations significantly reduce operating costs and can therefore contribute to lower hydrogen prices for end customers in the long term. The compact design enables easy integration into existing filling stations, making both new construction and retrofits significantly more cost-efficient. Operators benefit from lower investment hurdles and faster amortization. The robust design in combination with AI-supported condition monitoring enables predictive maintenance and ensures high plant availability. Investment costs can be reduced by up to 50% by dispensing with high-pressure accumulators and cooling power units. With a delivery rate of 600 kg/h, the CryoPump stations enable direct high-pressure refueling of a heavy-duty truck in less than ten minutes. This speeds up the refueling process, increases profitability for operators and significantly improves the everyday usability of hydrogen-powered commercial vehicles.
The CryoPump stations enable an efficient, economical and scalable refueling solution for mobility, heavy goods transport and logistics of the future.
