When the cell is gassing, the hydrogen and oxygen gasses are vented into the HYDROCAP. Inside a HYDROCAP, hydrogen and oxygen gases are catalytically recombined into pure water which is returned to the cells virtually eliminating explosive hydrogen gas concentrations, and washing acid fumes and vapors back into the battery cell.
It is possible to spot that, with the inclusion of the battery self-discharge loss, the available electrical energy has a steeper slope and decreases much faster than the hydrogen storage system.
However, the operation strategies are all predefined and fixed. Hydrogen storage and battery storage are also employed in grid-connected systems. Parra et al. studied the benefits of battery storage and hydrogen storage for a grid-connected single house .
The study suggests combining a hydrogen energy storage system with solar, wind, and hydrogen energy to lessen these problems. The objectives of this integration are to increase the use of renewable energy, encourage its consumption, and lower the rates at which solar and wind energy are being curtailed.
The hydrogen storage system consists of three major components: electrolyzer, hydrogen tank and fuel cell. The electrolyzer converts electrical energy into chemical energy through the decomposition of water into hydrogen (H 2) and oxygen (O 2 ). The produced hydrogen is compressed and fed into the hydrogen tank for storage.
