  2. Green hydrogen - Wikipedia

    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 storage - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_storage

    For many years hydrogen has been stored as compressed gas or cryogenic liquid, and transported as such in cylinders, tubes, and cryogenic tanks for use in industry or as propellant in space programs. The overarching challenge is the very low boiling point of H 2: it boils around 20.268 K (−252.882 °C or −423.188 °F).

  4. 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 ...

  5. 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.

  6. Combined cycle hydrogen power plant - Wikipedia

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

    By 2045, 100% hydrogen [ 1 ] A combined cycle hydrogen power plant is a power plant that uses hydrogen in a combined cycle power plant. 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.

  7. Hydrogen production - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_production

    Methods to produce hydrogen without the use of fossil fuels involve the process of water splitting, or splitting the water molecule (H 2 O) into its components oxygen and hydrogen. When the source of energy for water splitting is renewable or low-carbon, the hydrogen produced is sometimes referred to as green hydrogen. The conversion can be ...
