For areas that will predominantly need to continue using hydrocarbon fuels (e.g., aviation, shipping), what should be the role of scaling adoption of carbon neutral fuels (using biofuels or e-fuels integrating both DAC and green hydrogen) vs. continuing to burn unabated fossil fuels paired with a rigorous, credible use of Direct Air Capture? Most of these pathways for creating carbon neutral fuels are very capital intensive with high efficiency losses and suffer from their own challenges (biofuel concerns over land-use and limited feedstock availability and e-fuels being extremely expensive and inefficient due to needing to utilize both DAC and green H2 facilities). In most cases, wouldn't it be much more efficient and far cheaper (with equivalent climate outcomes) to continue burning fossil hydrocarbons and separately ensuring that sufficient levels of DAC are deployed to offset the emissions? What am I missing here?
