GrInHy project (Green Industrial Hydrogen via reversible high-temperature electrolysis) announced that since June 2017, the RSOC system was operated for more than 7,000 hours.

Over the course of operation, two long-term steady state operation phases in natural gas fuel cell mode and electrolysis mode were accomplished, each about 1,500 hours long.

The hours of electrolysis and fuel cell operation have been limited by challenges of the Hydrogen Processing Unit resulting in both software and hardware optimization.

The NG-FC operation proofed the reversibility of the system and showed its ability to produce power at efficiencies over 50 %LHV. Also first results on shut-down, start-up and switch-over times were gathered.

The electrolysis operation demonstrated for the first time the possibility to integrate a high temperature electrolysis as hydrogen supplier into an existing industrial site. It also showed high efficiencies up to 80 %LHV. One third of the produced hydrogen has been fed in the hydrogen pipeline.

About GrInHy

As a proof-of-concept, the GrInHy project (Green Industrial Hydrogen via reversible high-temperature electrolysis) includes designing, manufacturing and operation of a reversible generator based on the Solid Oxide Cell technology in a relevant industrial environment.

The project has been granted funding under the call FCH-02.4-2015.
