Green hydrogen is indispensable for a climate-neutral world. Whether in transportation, buildings, or the manufacturing industry – it makes sense to use it in nearly every sector. Bosch is H2 ready, and was an early mover in areas such as the development of fuel-cell technology. Along the entire hydrogen value chain, the company is developing technologies for the production, compression, storage, and use of hydrogen. At the Bosch Tech Day 2023, the company is providing some insights into its portfolio of products and services.
Bosch not only plans to use hydrogen, but also to provide smart technology for its production. For this purpose, Bosch is developing the electrolysis stack, the central element of an electrolyzer. The stack comprises more than 100 electrolysis cells that use electricity to split water into oxygen and hydrogen. It is designed for an output of 1.25 megawatts. That is equivalent to the production of 23 kilograms of H2 per hour. On the hydrogen side, the resulting pressure is more than 30 bar. The Bosch electrolysis stack is suitable for use in smaller-scale plants producing 1 megawatt and more, all the way up to large, gigawatt-scale plants.
It is expected to be market-ready from 2025. First pilot projects with customers are in preparation and will start next year. In addition, Bosch is planning to combine the electrolyzer stack with a control unit, power electronics, and various sensors to create a “smart electrolysis module.” These elements are designed to be compatible and save space, and optimize systems efficiency, reliability, installation, and setup.
