Hydrogen refueling station with solid-state hydrogen storage
Wind, solar energy, and hydropower are available for hydrogen production by electrolysis of water; the hydrogen produced is transported by magnesium-based solid-state hydrogen storage trailers to hydrogen refueling stations, where hydrogen fuel cell vehicles are filled with hydrogen.
Since the discharge temperature of SOFC is up to 600°C, it's of high value in use. Because the fast hydrogen discharge from magnesium-based solid-state hydrogen storage materials requires a temperature of 350°C, the SOFC waste heat can be recycled and reused; the combination system consisting of SOFC and magnesium-based solid-state hydrogen storage trailer is not only efficient, but it's also more eco-friendly.
Production of high-purity hydrogen and recycled hydrogen
Industrial by-product hydrogen can be injected into the storage system after the removal of oxidizing impurities (desulfurization, deoxidization and moisture removal); magnesium-based solid-state hydrogen storage materials can effectively remove CO, H2S and other impurities for the purification of hydrogen.
Hydrogen is a viable energy storage medium for industrial-scale renewable energy generation. The electric power from wind curtailment and solar curtailment that is difficult to use efficiently can be converted into hydrogen and stored through magnesium-based solid-state hydrogen storage trailers for long-term safe storage across seasons at normal temperatures and pressures.
