  2. Hydrogen infrastructure - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_infrastructure

    Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, pipeline transport costs are similar to CNG, [9] the technology is proven, [10] however most hydrogen is produced on the place of demand with every 50 ...

  3. Hydrogen economy - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_economy

    Hydrogen can be deployed as a fuel in two distinct ways: in fuel cells which produce electricity, and via combustion to generate heat. [58] When hydrogen is consumed in fuel cells, the only emission at the point of use is water vapor. [58] Combustion of hydrogen can lead to the thermal formation of harmful nitrogen oxides emissions. [58]

  4. Hydrogen train - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_train

    Hydrogen is a common and easy to find element, given that each molecule of water has two atoms of hydrogen for every oxygen atom present. [10] Hydrogen can be separated from water via several means, including steam reforming (normally involving the use of fossil fuels) and electrolysis (which requires large amounts of electricity and is less commonly used).

  5. 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.

    Hydrogen fuel cell powered Mercedes-Benz Citaro at Stratford in 2004. In January 2004, three hydrogen fuel cell powered buses were introduced on route 25 on a two-year trial. [20] [21] These were transferred to route RV1 in September 2004, [22] and were tested in commercial service on the route at peak times only. They were withdrawn in January ...

  7. 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 ...

    Japan got its first commercial hydrogen fueling station in 2014. [107] By March 2016, Japan had 80 hydrogen fueling stations, and the Japanese government aims to double this number to 160 by 2020. [108] In May 2017, there were 91 hydrogen fueling stations in Japan. [109] Germany had 18 public hydrogen fueling stations in July 2015.

  9. Alternative fuel - Wikipedia

    en.wikipedia.org/wiki/Alternative_fuel

    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 ...
