How do I read this chart? Values above the curve mean Solar+DAC is better than DAC+oil?
Great Q. There's a phase diagram for that in our Carbon Neutral Hydrocarbons paper https://keith.seas.harvard.edu/publications/carbon-neutral-hydrocarbons …. Number are wrong the the tradeoffs are right. At low-oil and high-solar prices and offsets win, but as solar gets cheaper air-to-fuels will win https://twitter.com/dr_olsson/status/1187773925301870592 …pic.twitter.com/L9q4ytkmys

In lower left (low carbon price and low oil price) it's BAU, just pay the tax. To the right "indirect" you pay for DAC+CCS as offset. Above the line you pay for synthetic fuels. Y-intercept is where synthetic fuels beat oil with no incentive. (These numbers too optimistic)
