Hydrogen can be produced when there is a surplus of variable renewable electricity, then stored and used to generate heat or to re-generate electricity. [136] Hydrogen created through electrolysis using renewable energy is commonly referred to as "green hydrogen". [137] It can be further transformed into synthetic fuels such as ammonia and ...
The concept of a society that uses hydrogen as the primary means of energy storage was theorized by geneticist J. B. S. Haldane in 1923. Anticipating the exhaustion of Britain's coal reserves for power generation, Haldane proposed a network of wind turbines to produce hydrogen and oxygen for long-term energy storage through electrolysis, to help address renewable power's variable output.

Hydrogen gas is produced by several industrial methods. [1] Nearly all of the world's current supply of hydrogen is created from fossil fuels. [2] [3]: 1 Most hydrogen is gray hydrogen made through steam methane reforming. In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas.
As COVID-19 starts to take up less of the world's attention, the issue of climate change and green energy is growing. It's impossible to ignore the impact of fossil fuels and pollution on our ...
Green hydrogen is being touted around the world as a clean energy solution to take the carbon out of high-emitting sectors like transport and industrial manufacturing. The India-led International ...
Why the interest in hydrogen Dr. Tim Liewen is the executive director of Georgia Institute of Technology’s Strategic Energy Institute and a professor in the School of Aerospace Engineering is at ...
Hydrogen evolution reaction (HER) is a chemical reaction that yields H 2. [1] The conversion of protons to H 2 requires reducing equivalents and usually a catalyst. In nature, HER is catalyzed by hydrogenase enzymes. Commercial electrolyzers typically employ supported platinum as the catalyst at the anode of the electrolyzer.
Its plastic properties prevent the formation and spread of fractures and protect it from losing its tightness, which is particularly important for hydrogen storage. [141] Some of the disadvantages of salt caverns include lower storage capacity, large amount of water needed, and the effect of corrosion.
