Hydrogen storage and batteries should not be viewed as competitors for providing flexibility to the power system; instead, they complement each other in important ways. The ideal mix may be using batteries to provide short-term flexibility (minutes or hours), while reserving hydrogen for long-term flexibility over weeks or months.
Results from the reviewed projects indicate that the best solution from a technical viewpoint consists in hybrid systems where hydrogen is combined with short-term energy storage technologies like batteries and supercapacitors.
The specific type of control system (PLC, SCADA, etc.), algorithm (FLC, SMCS, etc.) and power electronics (converter, etc.) should therefore be chosen based on the conditions and goals for each system. The main challenge and frequent showstopper with hydrogen energy storage systems is cost.
Compared to pumped storage and electrochemical energy storage, it is pollution-free and not affected by the environment. The high energy density and simplicity of storage make hydrogen energy ideal for large-scale and long-cycle energy storage, providing a solution for the large-scale consumption of renewable energy.
The use of hydrogen improved the control over the overcharge and undercharge of the battery and ultracapacitor, and it also minimized the high-stress current ratio in the battery, while the use of battery and ultracapacitor made it possible to avoid fluctuating operating conditions in the hydrogen system .
Lithium-ion batteries are part of the proposed system configuration in order to react to too rapid load changes, which the hydrogen system would not be able to handle. The heat waste generated by the fuel cell and the electrolyzer is transferred via heat exchangers to a hot water tank, which supplies hot water to the household.

Two emerging storage technologies are battery storage (BS) and green hydrogen storage (GHS) (hydrogen produced and compressed with clean-renewable electricity, stored, then returned to electricity with a fuel cell). An important question is whether GHS alone decreases system cost versus BS alone or BS + GHS.
So-called "power-to-gas" and "power-to-fuel" technologies are promising solutions for the short/medium term.The idea is to combine "green" hydrogen with CO 2 taken from the atmosphere or captured at a factory''s flue-gas stacks to produce hydrocarbons or synthesis gases. In addition to their extremely low carbon footprint, these technologies have …
It is assumed here that hydrogen used for grid electricity will be stored as a compressed gas. More expensive and energy-intensive liquefied hydrogen storage is needed only when space is a constraint, such as when …
