2. Natural hydrogen - Wikipedia

   en.wikipedia.org/wiki/Natural_hydrogen

   Natural hydrogen is believed to exist in economically viable concentrations and locations on every continent. [6] Natural hydrogen may be capable of supplying mankind's "projected global hydrogen demand for thousands of years," is non-polluting, may be available at significantly lower end user costs per therm than industrial hydrogen , and may ...

3. 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 ...

4. Hydrogen economy - Wikipedia

   en.wikipedia.org/wiki/Hydrogen_economy

   The Hydrogen Expedition is currently working to create a hydrogen fuel cell-powered ship and using it to circumnavigate the globe, as a way to demonstrate the capability of hydrogen fuel cells. [133] In August 2021 the UK Government claimed it was the first to have a Hydrogen Strategy and produced a document. [134]

5. 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 ...

   Green hydrogen is being touted around the world as a clean energy solution to take the carbon out of high-emitting sectors like transport and industrial manufacturing. The India-led International ...

7. 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 ...

8. HCNG - Wikipedia

   en.wikipedia.org/wiki/HCNG

   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. Fuel gas - Wikipedia

   en.wikipedia.org/wiki/Fuel_gas

   Fuel gas is widely used by industrial, commercial and domestic users. Industry uses fuel gas for heating furnaces, kilns, boilers and ovens and for space heating and drying . The electricity industry uses fuel gas to power gas turbines to generate electricity. The specification of fuel gas for gas turbines may be quite stringent. [5]
