What is the cost of usable energy for driving and heating our homes?

Green Car Congress

This analysis compares the costs of usable energy when we buy gasoline and electricity for driving and natural gas for keeping warm. Combustion of a gallon of gasoline (that includes ethanol) releases 120,333 Btu of energy. The average retail cost of regular gasoline in 2018 was $2.719 per gallon. by Michael Sivak.

Japan team evaluates battery-assisted low-cost hydrogen production from solar energy

Green Car Congress

The results from this study suggested a cost of hydrogen as low as ¥17 to ¥27/Nm 3 (US$0.16 - $0.25) using a combination of technologies and the achievement of ambitious individual cost targets for batteries, PV, and electrolyzers. For comparison, the US DOE’s 2020 target for the levelized cost of hydrogen (production only) is $2.30/kg.
