“Sustainable” petrol seems like a magical idea. Find a way toremove CO 2from the atmosphere, then turn that captured carbon into petrol by adding hydrogen to form the hydrocarbon molecules of petrol. So when you combust it, you’re merely sending the CO 2back up, rather than creating CO 2 from what has been trapped underground for millennia. It’s a net zero closed loop. And it works with the all petrol cars and fuel stations we already have. Huzzah!
