- 100 kg of hydrogen in less than 10 minutes.
- More than 100 refueling operations each day
At Hannover Messe 2024, Bosch Rexroth presents drive systems for compressors and cryopumps developed together with manufacturers and operators from Europe and the USA for the economical operation of hydrogen filling stations with short refueling times.
Full steam ahead towards a nationwide hydrogen filling station network
According to a decision by the European Union, hydrogen filling stations for cars and heavy comercial vehicles must be installed in all urban nodes and every 200 km along the trans-European transport network by 2030. The USA has set itself ambitious targets too. The Fuel Cell and Hydrogen Association predicts that around 4,300 hydrogen filling stations will be needed in the USA in 2030. “With our new technical solutions and in close collaboration with partners from the hydrogen industry, we can provide outstanding support in achieving these goals,” said Dr. Steffen Haack, Chairman of the Executive Board of Bosch Rexroth AG.
Refueling with hydrogen is much more technically complex than with petrol and diesel filling stations or electric charging stations. The challenge: Hydrogen is stored on site either in liquid form at -253 °C or as a gas in tanks with various pressure levels. In order to refuel vehicles, the hydrogen must be compressed in a controlled manner to between 700 and 900 bar. Robust drives for the compressors are needed here.
100 kg of hydrogen in less than 10 minutes.
Based on its decades of experience in hydraulics, Bosch Rexroth is developing customized solutions for an economical hydrogen infrastructure, working together with partners. The aim is to refuel Heavy Goods Vehicles (HGVs) with 100 kg of hydrogen in less than 10 minutes. With a tank full of fuel, HGVs can travel around 1,000 km.
Working with the market leader for the commercial operation of hydrogen filling stations in the USA, FirstElement Fuel in California, Bosch Rexroth has for example developed a cryopump that can compress up to 600 kg of liquid hydrogen per hour. The cryopump, which will be presented for the first time at Hannover Messe 2024, combines proven servohydraulic pump drives, software and a newly developed compression cylinder. The first filling stations will be equipped with the new technology from 2025.
More than 100 refueling operations each day
The cryopump is just one example of the various compressor drives in the product portfolio. Bosch Rexroth also offers other drive solutions for compressing both gaseous and liquid hydrogen. Rexroth products in different performance classes cover a wide range of applications: From in-house filling stations for forklift trucks in logistics centers to car filling stations and filling stations for heavy HGVs.
The solutions from Bosch Rexroth are based on series components and use hydrostatic transmission systems that are particularly robust and compact. The drive systems for compressors can be installed in small spaces. Compared to previous electromechanical pump drives, they offer a significantly higher flow rate and are much more efficient. Designed for continuous operation, they can be used for several hundred refueling operations a day operating in start-stop mode.
Bosch is developing technologies for the production, compression, storage and use of hydrogen along the entire value chain. By 2030, Bosch aims to achieve a turnover of around five billion euros with this business segment. Between 2021 and 2026, the company will invest a total of around 500 million euros annually in the development and production of its H2 technologies.
