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.

Economic gains Hydro is a flexible source of electricity since plants can be ramped up and down very quickly to adapt to changing electrical demands. [ 48 ] The cost of operating a hydroelectric plant is nearly immune to changes in the cost or availability of fossil fuels such as oil , natural gas or coal , and no imports are needed.
Pros and cons of various types of renewable energy are being investigated, and more recently there have been trials of green hydrogen and wave power. Australia ratified the Kyoto protocol in 2007, and in 2016 became a party to the Paris Agreement, an international agreement that binds member countries to address climate change.
According to the U.S. Department of Energy, "Eventually hydrogen will join electricity as the major energy carrier, supplying every end-use energy need in the economy, including transportation, central and distributed electric power, portable power, and combined heat and power for buildings and industrial processes."

As of 2021, green hydrogen accounted for less than 0.04% of total hydrogen production. [5] Its cost relative to hydrogen derived from fossil fuels is the main reason green hydrogen is in less demand. [6] For example, hydrogen produced by electrolysis powered by solar power was about 25 times more expensive than that derived from hydrocarbons in ...
Hydrogen technologies are applicable for many uses. Some hydrogen technologies are carbon neutral and could have a role in preventing climate change and a possible future hydrogen economy . Hydrogen is a chemical widely used in various applications including ammonia production, oil refining and energy. [ 1 ]
