Hydrogen storage is a relatively new method for storing wind power. It involves using wind power to split water into hydrogen and oxygen through a process called electrolysis. The hydrogen is then stored, and when the power is needed, it can be burned in a fuel cell to generate electricity. Hydrogen storage has a high storage capacity and can ...
For wind power smoothing purposes, many researchers have been using energy storage systems (ESSs) as they perform extremely well, and are becoming less costly.

The wind power gap between 0 kW (BESS discharge beginning) and 230 kW (BESS discharge ceasing) ensures that the battery doesn''t continually start and stop when the wind speed is around cut-in. This step was included to improve the BESS''s lifetime, but by April 2016, this was determined to be unnecessary.
