With its roadmap for moving to a competitive low-carbon economy in 2050, the European Commission sets greenhouse gas emissions targets for different economic sectors . A main challenge will be the integration of renewable energy sources into industrial processes to avoid carbon dioxide emissions.

The vision of GrInHy is to provide green hydrogen via electrolysis and also to stabilize the grid at the same time as reversible generator. Because a significant share of the energy input is preferably provided in the form of waste heat, high-temperature electrolysis achieves higher electrical system efficiencies and, therefore, is one of the most promising technologies to fulfill this vision.

Besides the steel industry, which is already addressed in the project, green industrial hydrogen can be used as a feed material for various industrial applications, e.g. in the chemical industry, food processing, metallurgy, glass production, electronics manufacturing and power plant generator cooling.
