  3. Hydrogen economy - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_economy

    A 2022 Goldman Sachs analysis anticipates that globally green hydrogen will achieve cost parity with grey hydrogen by 2030, earlier if a global carbon tax is placed on gray hydrogen. [13] In terms of cost per unit of energy, blue and gray hydrogen will always cost more than the fossil fuels used in its production, while green hydrogen will ...

  4. Hydrogen production - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_production

    At an electricity cost of $0.06/kWh, as set out in the Department of Energy hydrogen production targets for 2015, [73] the hydrogen cost is $3/kg. The US DOE target price for hydrogen in 2020 is $2.30/kg, requiring an electricity cost of $0.037/kWh, which is achievable given recent PPA tenders for wind and solar in many regions. [74]

    Therefore, the amount of mass that can be lifted by hydrogen in air at sea level, equal to the density difference between hydrogen and air, is: (1.292 - 0.090) kg/m 3 = 1.202 kg/m 3. and the buoyant force for one m 3 of hydrogen in air at sea level is: 1 m 3 × 1.202 kg/m 3 × 9.8 N/kg= 11.8 N

  6. Electrolysis of water - Wikipedia

    en.wikipedia.org/wiki/Electrolysis_of_water

    The US DOE target price for hydrogen in 2020 is $2.30/kg, requiring an electricity cost of $0.037/kW·h, which is achievable given 2018 PPA tenders [76] for wind and solar in many regions. This puts the $4/gasoline gallon equivalent (gge) H 2 dispensed objective well within reach, and close to a slightly elevated natural gas production cost for ...

  7. 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 ...

  9. Gasoline gallon equivalent - Wikipedia

    en.wikipedia.org/wiki/Gasoline_gallon_equivalent

    The fuel consumption is an equivalent measure for cars sold outside the United States, typically measured in litres per 100 km traveled; in general, the fuel consumption and miles per gallon would be reciprocals with appropriate conversion factors, but because different countries use different driving cycles to measure fuel consumption, fuel ...
