03.2024 | Hydrogen from biogas with WS Group technology

Producing green hydrogen from biogas is an excellent way to support the ramp-up of the hydrogen economy. Immediately usable and decentrally distributed production options offer optimal conditions for this. The system is designed for economical production for regional use of hydrogen - a real gain in self-sufficiency and resilience for municipalities.

05.2023 | WS Group invests into its future!

With a total investment volume of almost 10 million euros, the WS Group around its core company WS Wärmeprozesstechnik GmbH is making itself fit for the future. In addition to new buildings for storage and production areas, extensive investments into advanced research and development facilities are currently being implemented.


Already under construction is an electrolyzer that will produce green hydrogen from locally generated solar power, which will then be used in the WS labs for extensive development and testing of modern heating systems. Also, just about to be commissioned is a plant to supply the research department with ammonia (NH3), a carbon-free hydrogen carrier. Ammonia has great potential to play a major role in the future energy system. Suitable heating systems and reformer plants have already been developed for many years within the WS Group and today find rapidly growing demand in different market areas.


In addition to the technology investments, the company premises will be extended by several new buildings at an additional location in Renningen. The extensive expansions thus create the necessary space to accommodate the constant growth of the WS Group. In particular, the efficient assembly of larger plants in the field of green hydrogen production from biogas as well as other specialized reformer applications will be enabled. At the same time, the construction projects are a long-term commitment to the WS Group's home base in Renningen near Stuttgart.


WS consistently relies on sustainable raw materials for the new properties. The buildings will be built using timber construction and the on premise generation of green electricity will be maximized. The planned wooden facades and lush greenery also reflect the essence of the WS Group. After all, sustainability and energy efficiency have been at the heart of everything WS does for over 40 years already.

Focus 2022
10.2022 | Green hydrogen from manure

On October 28, 2022, the consortium of BtX energy GmbH, e-flox GmbH and WS Reformer GmbH presented a pilot plant for the production of green hydrogen from biogas. In particular, liquid manure and other biogenic residues can be considered as feedstock for small-scale plants. 


Regional value creation and security of supply are just two aspects that make the project so interesting that it is being funded by the BMWi in the large-scale BioH2Ref research project.

High-ranking visit from China

Several high-ranking delegations from China visited WS in Renningen to find out about the best industrial burner technology available. The focus of the visit was on the low-emission and efficient heating of electric conveyor belt systems. Due to the increasing production of electric vehicles, this market segment is currently experiencing an upswing, particularly in Asia.



FlexHeat2Anneal is a funded research project investigating the flexible use of hydrogen as a fuel for continuous process lines and galvanizing lines.
