Zinc intermediate step electrolysis from STOFF2 becomes part of the innovative “Hydrogen Terminal Braunschweig” research project

  • STOFF2 and Steinbeis Innovation Centre energieplus in Braunschweig launch a pioneering collaboration
  • As part of the “Hydrogen Terminal Braunschweig” research project, the partners intend to build and operate an electrolyzer produced by STOFF2 

Berlin, 30 July 2024: STOFF2 has developed a technology that combines the functions of a battery and an electrolyser in a single system, the Zinc intermediate step electrolysis (ZZE). STOFF2’s technology addresses both the sustainable and efficient production of green hydrogen and the optimal use of fluctuating renewable energies made available for all sectors.

The “Hydrogen Terminal Braunschweig” research project was launched in 2020 by Steinbeis Innovation Centre energieplus (SIZ) and the Technical University of Braunschweig. In particular, it aims to pool expertise along the H2 value chain and to realise important research projects in this area. 

First application of the zinc intermediate step electrolysis in an industrial environment

Participation in the “Hydrogen Terminal Braunschweig” project is an important milestone for STOFF2, as its ZZE is to be installed in an industrial environment for the first time worldwide. STOFF2 will be responsible for the technical design of the for the research project at SIZ. In particular, this will involve the interaction of the ZZE electrolyzer with the existing power and H2 infrastructure on site. In a second step, the project partners intend to commission the designed STOFF2 electrolyzer on site.

Utilisation of green hydrogen for heavy-duty mobility and testing environment

The green hydrogen will be produced on site with electrolyzers from STOFF2 as well as Enapter and a ZZE electrolyzer. The produced GH2 will be used in test benches for research work as well as injected into the local H2 gas network to supply other external consumers such as the Fraunhofer Project Centre for Energy Storage and Systems (Fraunhofer ZESS) and the Lower Saxony Research Centre for Automotive Engineering (NFF). At the “Hydrogen Terminal Braunschweig” site, the hydrogen produced is also used to operate a hydrogen refuelling station for heavy goods vehicles with the support of a compressor from Maximator. 

Forward-looking cooperation

With this joint project, STOFF2 and SIZ energieplus are taking an important step towards the further development and implementation of advanced energy technologies. 

“We are excited to start driving innovation in this partnership and look forward to contributing our highly innovative technology to this pioneering project,” says Sebastian Sipp, Managing Director of STOFF2.

“With the zinc intermediate step electrolysis, we will open up completely new possibilities to enable optimization modes of operation utilizing fluctuating renewable energies to secure continuous supply of green hydrogen,” says David Sauss, Scientific Director of SIZ energieplus.
