Off-grid power supply based on solar photovoltaic input in which continuity of supply is guaranteed by generation of hydrogen via electrolysis, hydrogen storage and electricity generation by a fuel cell when direct supply is unavailable, such as at night and in periods of dull or rainy weather.
The global grid energy storage market was estimated at 9.5‒11.4 GWh/year in 2020 (BloombergNEF (2020); IHS Markit (2021)7). By 2030, the market is expected to exceed 90 GWh, with some projections surpassing 120 GWh. Reaching 90 or 120 GWh represents compound annual growth rates (CAGRs) of 23% and 29%, …
