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 cost of hydrogen production by reforming fossil fuels depends on the scale at which it is done, the capital cost of the reformer, and the efficiency of the unit, so that whilst it may cost only a few dollars per kilogram of hydrogen at an industrial scale, it could be more expensive at the smaller scale needed for fuel cells.
The challenges facing the use of hydrogen in vehicles include its storage on board the vehicle. As of September 2023, hydrogen cost $36 per kilogram at public fueling stations in California, 14 times as much per mile for a Mirai as compared with a Tesla Model 3. [131]
However, a good rule of thumb: Eating 500 fewer calories per day will help you drop about one pound a week. That might not sound like a lot, but slow and steady weight loss is key, explains Werner.
