Hydrogen storage plays a critical role in integrating renewable energy sources like wind and solar power into the grid. Excess renewable energy can be used to produce hydrogen through electrolysis, which can then be stored and converted back into electricity or used in other applications when needed.
The electrolytic cell is the core of the hydrogen storage system, in which electrical energy is converted into heat and chemical water to obtain O 2 and hydrogen. The compressor is used to compress H 2 and store it in the high-pressure gas storage tank [18,19,29]. Fig. 10. Hydrogen storage system.
Solar and wind power intermittency and demand non-coincidence require storage. Hydrogen energy storage is one of the only options with sufficient storage capacity. Hydrogen can provide seasonal storage, zero emissions fuel and chemical feedstock. Gas grid can evolve, store and distribute increasing hydrogen amounts at low cost.
Hydrogen offers a potential energy storage medium because of its versatility. The gas can be produced by electrolysis of water, making it easy to integrate with electricity generation. Once made, the hydrogen can be burned in thermal power plants to generate electricity again or it can be used as the energy source for fuel cells.
Although the technological cost of hydrogen used for transportation is high because of its long chain and low efficiency from electrolysis water to fuel-cell, the cost of hydrogen used for electric energy storage is low , giving it a competitive advantage in the long-term-fixed large-scale energy storage scenario.
The successful development of hydrogen storage solutions is essential for the penetration of hydrogen at each level of the energy supply chain. The application of hydrogen in the energy economy can be attributed to two categories: stationary and mobile.
Underground storage facilities benefit from several advantages to cope with hydrogen such as the absence of oxygen underground or the high fluid pressure. Hy-drogen storage in salt caverns is already a proven tech-nology with several sites in the North of England and in the United States.
Hydrogen storage plays a critical role in integrating renewable energy sources like wind and solar power into the grid. Excess renewable energy can be used to produce hydrogen through electrolysis, which can then be stored and converted back into electricity or used in other applications when needed.
Producers can separate hydrogen from water through electrolysis, powered by solar cells or wind turbines. Later, on converting hydrogen into electricity, the only by-product is water. Between plant production and the fuel cell, safe and efficient hydrogen storage is essential for this energy source to become practicable and economical.
