My issue is that this is a step in the wrong direction, it is incentivizing the current dirty status quo. Why would anyone replace their dirty engine if they can feel good about by using your 'cleaned' fuel. I agree we need to do something now, but this is just putting off the inevitable. Re-engineering dirty fuel sources doesn't buy us time to resolve this. It is procrastinating, shuffling titanic deckchairs. The main advantage of this tech I can see is making 'primary' sourced fuel illegal, 'secondary' sourced fuel like this prohibitively expensive, and forcing everyone to go pure electric engine by economy.
