The following table shows a range of estimates of the levelized costs of gray, blue, and green hydrogen, expressed in terms of US$ per kg of H 2 (where data provided in other currencies or units, the average exchange rate to US dollars in the given year are used, and 1 kg of H 2 is assumed to have a calorific value of 33.3kWh).
Graphite flakes can cost around US$0.9/kg carbon. [20] Price of synthetic industrial diamond for grinding and polishing can range from 1200 to 13 300 USD/kg, while cost per weight of large synthetic diamonds for industrial applications can be on the order of million dollars per kilogram. [21] 7: N: Nitrogen: 0.0012506: 19 (5.263 × 10 17 kg) 0. ...
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]
At an electricity cost of $0.06/kW·h, as set out in the US Department of Energy hydrogen production targets for 2015, [75] the hydrogen cost is $3/kg. Equipment cost depends on mass production. Operating cost depends on electricity cost for about half of the levelised product price. [72] [71] H 2 production cost ($-gge untaxed) at varying ...
The United States produces 9–10 million tons of hydrogen per year, mostly with steam reforming of natural gas. [13] The worldwide ammonia production, using hydrogen derived from steam reforming, was 144 million tonnes in 2018. [14] The energy consumption has been reduced from 100 GJ/tonne of ammonia in 1920 to 27 GJ by 2019. [15]

Its cost relative to hydrogen derived from fossil fuels is the main reason green hydrogen is in less demand. [6] For example, hydrogen produced by electrolysis powered by solar power was about 25 times more expensive than that derived from hydrocarbons in 2018. [7] By 2024, this cost disadvantage had decreased to approximately 3x more expensive ...
