Jet fuel energy content is approx. 37 kWh/gallon. At 40% efficiency that's 92.5 kWh. At $0.01/kWh, $92.5 cents per gallon for energy cost. Spot price for jet fuel is approx. $2.00 average over 2006-2021 https://www.eia.gov/dnav/pet/hist/LeafHandler.ashx?n=PET&s=E...
Add to this the LCFS credits which can be over $1.50 and there is a lot of room for Capex.
Not sure how we got to $0.01/kWh (half the cost of the lowest PPAs ever signed for solar in Saudi Arabia), but if the electricity cost is 10x lower than current California prices, I see how electrofuels could pencil.
