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.

The provenance of hydrogen fuel varies – with green hydrogen (produced using renewable electricity) being significantly more environmentally friendly than brown hydrogen (produced by burning coal or lignite) or grey hydrogen (produced by steam heating natural gas).
Alternative fuel including gaseous fuels such as hydrogen, natural gas, and propane; alcohols such as ethanol, methanol, and butanol; vegetable and waste-derived oils; and electricity. These fuels may be used in a dedicated system that burns a single fuel, or in a mixed system with other fuels including traditional gasoline or diesel, such as ...
The large-scale roll-out of hydrogen tech has also been restricted because of the high costs involved in separating it from hydrocarbons. Researchers discover climate-friendly way of extracting ...
Hydrogen can be deployed as an energy source in fuel cells to produce electricity, or via combustion to generate heat. [169] When hydrogen is consumed in fuel cells, the only emission at the point of use is water vapour. [169] Combustion of hydrogen can lead to the thermal formation of harmful nitrogen oxides. [169]
Hydrogen can be produced from water by electrolysis.Electrolysis powered by renewable energy is carbon neutral.The business consortium Hydrogen Council said that, as of December 2023, manufacturers are preparing for a green hydrogen expansion by building out the electrolyzer pipeline by 35 percent to meet the needs of more than 1,400 announced projects.
