    en.wikipedia.org/wiki/Green_hydrogen

    Hydrogen can be produced from water by electrolysis.Electrolysis powered by renewable energy is carbon neutral.The 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.

  3. Hydrogen economy - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_economy

    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.

  4. Hydrogen storage - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_storage

    A German case study on storage of hydrogen in salt caverns found that if the German power surplus (7% of total variable renewable generation by 2025 and 20% by 2050) would be converted to hydrogen and stored underground, these quantities would require some 15 caverns of 500,000 cubic metres each by 2025 and some 60 caverns by 2050 ...

  5. Combined cycle hydrogen power plant - Wikipedia

    en.wikipedia.org/wiki/Combined_cycle_hydrogen...

    A green hydrogen combined cycle power plant is only about 40% efficient, after electrolysis and reburning for electricity, and is a viable option for energy storage for longer term compared to battery storage. Natural gas power plants could be converted to hydrogen power plants with minimal renovation or do a combined mix of natural gas and ...

  6. Hydrogen technologies - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_technologies

    Hydrogen is not a primary energy source, because it is not naturally occurring as a fuel. It is, however, widely regarded as an ideal energy storage medium, due to the ease with which electricity can convert water into hydrogen and oxygen through electrolysis and can be converted back to electrical power using a fuel cell or hydrogen turbine. [3]

  7. Hydrogen fuel cell power plant - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_fuel_cell_power_plant

    A hydrogen fuel cell power plant is a type of fuel cell power plant (or station) which uses a hydrogen fuel cell to generate electricity for the power grid. They are larger in scale than backup generators such as the Bloom Energy Server and can be up to 60% efficient in converting hydrogen to electricity. There is little to no nitrous oxide ...
