Hydrogen can be used in combination with electrolytic cells and fuel cells, not only as energy storage but also for frequency regulation, voltage regulation, peak shaving, and valley filling, cogeneration and industrial raw materials on the load side, contributing to the diversified development of high proportion of renewable energy systems.
The use of a hydrogen conversion and storage system yields total annualized cost reductions of 72–80% for the self-sufficient supply of electricity and heat throughout the year compared to lithium-ion battery systems.
Conceived by a Dutch research group, the proposed system is intended to store surplus renewable electricity via hydrogen generation and battery storage, with the latter being used only when hydrogen generation is not immediately available. Despite its high initial costs, the system can reportedly offer stable operation. Schematic of the system
All the hydrogen is stored in four small red hydride containers; the rest of this beefy cabinet is taken up with the electrolyzer, battery, and fuel cell stack And the final joy killer is the system's maximum continuous power output of 5 kW, limited presumably by the throughput of the fuel cell.
Compared to pumped storage and electrochemical energy storage, it is pollution-free and not affected by the environment. The high energy density and simplicity of storage make hydrogen energy ideal for large-scale and long-cycle energy storage, providing a solution for the large-scale consumption of renewable energy.
In particular, the electricity generated during periods of low load demand and low electricity prices can be stored in hydrogen to reduce the cost of electricity generation and generate electricity during times of high load demand and high electricity prices, making the system more profitable through peak-to-valley differences [77, 78].
