From https://pubs.rsc.org/en/content/articlelanding/2020/se/c9se0... > We find that an electricity emissions factor of less than 139 g CO2e per kW h is required for this [Direct Air Capture system paired with Fischer–Tropsch synthesis] pathway to provide a climate benefit over conventional diesel fuel. The grid averages in most regions are higher than that. I don't think multiplying current renewable generation just for jet fuel is easy. |
