  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 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.

  3. Hydrogen economy - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_economy

    The range of cost estimates for commercially available hydrogen production methods is broad, As of 2022, gray hydrogen is cheapest to produce without a tax on its CO 2 emissions, followed by blue and green hydrogen. Blue hydrogen production costs are not anticipated to fall substantially by 2050, [95] [92]: 28 can be expected to fluctuate with ...

  4. Renewable fuels - Wikipedia

    en.wikipedia.org/wiki/Renewable_fuels

    Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.

  5. Hydrogen production - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_production

    As of 2020, estimated costs of production are $1–1.80/kg for grey hydrogen and blue hydrogen, [177] and $2.50–6.80 for green hydrogen. [177] 94 million tonnes of grey hydrogen are produced globally using fossil fuels as of 2022, primarily natural gas, and are therefore a significant source of greenhouse gas emissions. [178] [179] [180] [181]

  6. Electrofuel - Wikipedia

    en.wikipedia.org/wiki/Electrofuel

    With the help of renewable electricity, water can be separated into its components, hydrogen and oxygen, as part of water electrolysis. To produce e-fuels, a synthesis gas consisting of hydrogen and carbon dioxide is provided, which is then converted into hydrocarbons in a subsequent synthesis process, which can then be used as a fuel.

  8. Steam reforming - Wikipedia

    en.wikipedia.org/wiki/Steam_reforming

    Illustrating inputs and outputs of steam reforming of natural gas, a process to produce hydrogen and CO 2 greenhouse gas that may be captured with CCS. Steam reforming or steam methane reforming (SMR) is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water.
