To me that's a big loss. It seems pretty clear we're not fixing this quickly enough and need to go quicker. A2F fuel is still hydrocarbon so will still spit out similar pollutants along with contributing to the associated health impacts. As the second half of the article notes it's far better not to have the pollution in the air in the first place. What about the economic, industrial, and environmental cost of creating and running the A2F infrastructure and process? In 10 years, probably less, most vehicles will have been replaced. Keeping internal combustion viable for +20 years will just avoid the issue and help delay the inevitable switch to renewables; be that electric, fuel cell, or something more exotic. Worst case scenario - in 20 years internal combustion is still pervasive, in part thanks to the adoption of A2F, with both fuels at the pump: oil sourced £2, A2F £2.10. So in 20 years I sincerely hope gas powered cars are not common, and are fast becoming an occasional historic entertainment found in clubs, tracks and preservation societies. Rather like steam trains and horses have perhaps. It could perhaps be very useful for aviation where renewables seem unlikely to make much impact any time soon.
