Project goals

The project is based on a feasibility study for the technical and economic assessment of a reversible solid oxide fuel cell (rSOC). This highly efficient technology decouples the production and use of green electricity. It produces hydrogen if electricity from renewable sources is cheaply available and converts energy back into electricity and heat in times of insufficient renewable energy. In the project a rSOC system with an output of 180 kWel (approx. 50 Nm³ /h H₂) is being developed and operated under market-related conditions.

Application

The rSOC-system is characterized by its special combination of fuel cell and electrolysis. Hydrogen can thus be stored, or otherwise used in industry as a substitute for fossil hydrogen in order to significantly reduce emissions. The operating mode can be changed from hydrogen generation to electricity and heat production within a very short time. As a result, the plant achieves a higher capacity utilization per year and is economically more attractive.

The final project report on the feasibility study is available in the HYPOS member area.
