Experimental Hydrogen Plant with Metal Hydrides to Store and Generate Electrical Power

An experimental power plant used to determine system efficiency standards for hydrogen storage and the power generation industry.

(De Gruyter) – Renewable energy sources do not produce energy constantly. It is therefore necessary to use stored energy that can then be connected to the distribution system. The authors discsuss the formation of an integrated power plant using metal hydride hydrogen storage, an alkaline electrolyzer, and PEM fuel cells for the storage and generatuion of electrical and heat energy. Each individual component of the power plant was analzyed for its energy efficiency. An overall efficiency of the power plant was limited to ~11% due to the low efficiencies of the commercial electrolyzers and power inverters used in the experiments. Further technological improvements of the less efficient components of the power plant are therefore neccessary in order to achieve an overall enhancement in energy efficiency.
