Does hydrogen storage provide a long-term power system based on renewable resources?

Many studies have been carried out to investigate the effect of hydrogen storage on a power system based on renewable resources, especially wind power. The potential of hydrogen for providing a long-term storage in different system architectures was evaluated by Lewandowska-Bernat et al. .

Can hydrogen be used as an energy storage solution?

Notably, integrating hydrogen as an energy storage solution amplified the challenges related to system sizing. While hydrogen offered remarkable energy density and could be produced from renewable sources, its high levelized cost of energy (LCOE) necessitated meticulous optimization to bring down the overall system LCOE.
