Hydrogen production and use in the Black Forest
Belenus GmbH, managed by Alexander Theinert, is a highly specialised company in the fields of sheet metal processing, welding and assembly. They not only manufacture tanks for the aerospace industry, but also laser parts and welded assemblies in different series sizes. With its modern machines and systems, Belenus is strongly committed to environmental protection and relies on sustainable energy generation. Its location in Bad Dürrheim, Black Forest, supports the ambitious goal of the community to become climate-neutral by 2030 – a project in which Belenus GmbH plays a central role.

Our role in the project
The sera Modular Energy System supports the on-site production and use of hydrogen. Initially, the water required for electrolysis is treated, which for the time being comes from the public water supply. The hydrogen produced is dried, processed and compressed by our compressor (AG300.1) from around 30 bar to 300 bar, and then stored in cylinder bundles. A manual overflow unit allows the customer to use the hydrogen to refuel their vehicle – without having to
make a detour to a distant petrol station. By using cistern water, Belenus also aims to conserve valuable water resources in the future.

Why our solution is convincing
Our modular system offers maximum flexibility. The customer can expand it with additional electrolysers and compressors as needed. The manual refuelling unit can easily be upgraded with more advanced solutions, such as fuel cells or a hydrogen heater. The system also impresses with its compact design and costeffective refuelling solution, which makes it possible to handle the entire H2 production and storage process in one efficient system.

Special features
The next step is to integrate our dosing technology to enable water treatment so that cistern water can also be used for hydrogen production.
