1. Introduction. Hydrogen storage systems based on the P2G2P cycle differ from systems based on other chemical sources with a relatively low efficiency of 50–70%, but this fact is fully compensated by the possibility of long-term energy storage, making these systems equal in capabilities to pumped storage power plants.
Battery storage can help with frequency stability and control for short-term needs, and they can help with energy management or reserves for long-term needs. Storage can be employed in addition to primary generation since it allows for the production of energy during off-peak hours, which can then be stored as reserve power.
Then the combination of a SMES and LH2 offers a novel hybrid energy storage option for simultaneously providing long- and short-term power. The most cost-effective solution will, of course, depend on the application-specific requirements, but a fast and efficient power conversion and control unit plays a key role in all cases.
"Firming" solar generation – Short-term storage can ensure that quick changes in generation don''t greatly affect the output of a solar power plant. For example, a small battery can be used to ride through a brief generation disruption from a passing cloud, helping the grid maintain a "firm" electrical supply that is reliable and
