Hydrogen-Oxygen parity at STEAG hydrogen project in Saarland

Hydrogen-Oxygen pairs up for success at STEAG hydrogen project in Saarland

STEAG GmbH intends to supply Nippon Gases Deutschland GmbH with oxygen from its site at Völklingen-Fenne in Saarland in the future.

The oxygen will soon be produced there as a by-product from the “HydroHub Fenne” electrolyzer planned by STEAG and its partner Siemens Energy for the production of green, i.e. climate-neutral, hydrogen. The gas will be supplied via an oxygen pipeline owned by Nippon Gases, to which STEAG’s long-established power plant site is already connected, and therefore no further investment in transport infrastructure is required.

The agreement now concluded with Nippon Gases is a sensible addition to the economic viability of this pioneering project for the future. The industrial gas manufacturer plans to purchase the additional oxygen (O2) produced for delivery to customers. The advantage for all parties involved is in the use of a pipeline network which is already in place in the Saar region to transport oxygen for reliable supply to the locally based steel industry.

The “HydroHub Fenne” project provides economic proof of the new electrolyzer’s added value resulting from the simultaneous use of hydrogen and oxygen. This agreement is another decisive step on the part of Nippon Gases to create added value for society and provide practical support for using new technologies.

“The agreement that has now been reached with Nippon Gases is a successful step in ensuring the profitability of the overall project,” says Karl Resch, who is in particular responsible for the area of “Sales & Origination” in STEAG’s Trading Division and was in charge of negotiating the Letter of Intent with Nippon Gases and Siemens Energy on behalf of STEAG.

STEAG’s project manager Philipp Brammen said, “The hydrogen (H2) produced in the process will make a significant contribution to the decarbonization of the steel industry in Saarland.”

Eric Klein, VP at Siemens Energy, said, “The marketing of the by-product oxygen, which is expected in the near future, shows that the HydroHub Fenne is a sustainable and forward-looking project in the best sense of the word. Not only can it provide hydrogen as a key element of a future climate-neutral energy system, but it also supplies the oxygen that is frequently needed in industrial processes.”

Together with its international partners Creos Deutschland, Encevo, GazelEnergie, GRTgaz, H2V, Hydrogène de France and Stahl-Holding-Saar, STEAG has also joined forces in the European Economic Interest Grouping (EEIG) “Grande Region Hydrogen”. In this respect, the future HydroHub Fenne is also an integral component of a cross-border hydrogen economy in Luxembourg, the French region of Lorraine (Grande-Est) and Saarland.
