Tiivistelmä
As the share of intermitted renewable energy increases, there will be a growing demand of grid balancing energy storage solutions. A new type of energy storage is using hydrogen gas as an energy carrier and reversible solid oxide cell (RSOC) technology to convert electricity to hydrogen and vice-versa.
This study aims to investigate the technical and economic performance of an RSOC and hydrogen gas storage system for grid balancing applications in office buildings. The optimal system configuration and operation is determined and the competitiveness of the system is ananalyzed. The results are based on a bilevel optimization model, which minimizes the life cycle costs (LCC) of the RSOC and hydrogen storage system.
The results of the study show that the RSOC and hydrogen storage system can not compete with alternative energy systems when connected to the grid and district heating network. The major drawbacks of the system are its high investment costs and mediocer performance.
