Hydrogen production can occur and subsequently be stored for future applications by harnessing excess renewable energy. This approach mitigates the variability of renewable energy supply and enhances its dependability, effectively smoothing out fluctuations in energy availability.
Comparison of hydrogen storage with other energy storage technologies. Hydrogen energy storage offers a practical way to address energy curtailment and enhance grid stability. The primary performance indicators for storage of hydrogen, lithium-ion batteries, and pumped hydro storage were previously detailed in Table 2.
Hydrogen storage lowers renewable energy curtailment by 8–13 %, improving grid stability. Electrolyser efficiency improvements could cut green hydrogen costs by 30 % by 2030. Hydrogen (120 MJ/kg) outperforms lithium-ion batteries (0.4 MJ/kg) for long-term energy storage.
Unlike traditional batteries, hydrogen storage facilities can store large amounts of energy for extended periods. Moreover, hydrogen can be transported and distributed efficiently, offering grid operators greater flexibility in managing energy resources across diverse geographical locations, as shown in Fig. 8.
