1 kg for a Dollar
The US under Biden has a goal of $1/kg hydrogen within a decade. This is 'clean hydrogen', which is not based on renewables. Ie, this is not Solar Hydrogen. . Note that the clean hydrogen is defined as 'hydrogen produced with a carbon intensity of 2 kg or less of carbon-dioxide equivalent produced at the site of production per kg of hydrogen produced'.
Compared to burning gasol
Comparison to Fossil Fuels
- 2 kg C02 per kg hydrogen produced saves 16% of the CO2 compared to burning gasoline directly. Gasoline gallon is 2.7 kg  and it produces 8.9 kg of CO2 . Thus, gasoline releases 3.3 kg CO2 per kg gasoline.
- Thus, the brown hydrogen used improves things 61%. Good, but not great. From the regenerative enterprise perspective, this is lame.
