  2. Carbon-neutral fuel - Wikipedia

    en.wikipedia.org/wiki/Carbon-neutral_fuel

    Carbon-neutral fuel is fuel which produces no net-greenhouse gas emissions or carbon footprint. In practice, this usually means fuels that are made using carbon dioxide (CO 2 ) as a feedstock . Proposed carbon-neutral fuels can broadly be grouped into synthetic fuels , which are made by chemically hydrogenating carbon dioxide, and biofuels ...

  3. New way to turn CO2 back into petrol as ‘carbon-neutral fuel’

    www.aol.com/news/new-way-to-turn-co-2-back-into...

    Carbon capture and storage (CCS) is one of the new technologies that scientists hope will play an important role in tackling the climate crisis.

  4. Carbon dioxide reforming - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_reforming

    Carbon dioxide reforming (also known as dry reforming) is a method of producing synthesis gas (mixtures of hydrogen and carbon monoxide) from the reaction of carbon dioxide with hydrocarbons such as methane with the aid of metal catalysts (typically Ni or Ni alloys).

  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. [15]

  6. 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.

  7. Emission standard - Wikipedia

    The government undertook consultation on the model for the standard in April and May 2023, and they intend to introduce legislation by the end of 2023 [80] Research commissioned by environmental NGO Solar Citizens has calculated that a Fuel Efficiency Standard that started at 95g CO2/km and reduced to 0g CO2/km over ten years would save ...

  8. HCNG - Wikipedia

    en.wikipedia.org/wiki/HCNG

    HCNG -CNG emission. HCNG or H2CNG (hydrogen compressed natural gas) is a mixture of compressed natural gas and 4–9 percent hydrogen by energy. [1] It may be used as a fuel gas for internal combustion engines [2] [3] [4] and home appliances.

  9. Hydrogen production - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_production

    Hydrogen may be used in fuel cells for local electricity generation or potentially as a transportation fuel. Hydrogen is produced as a by-product of industrial chlorine production by electrolysis. Although requiring expensive technologies, hydrogen can be cooled, compressed and purified for use in other processes on site or sold to a customer ...
