THS, as the old fart in question, I do not doubt that synthetic aviation fuels can be manufactured. The Luftwaffe depended on them when that from the Ploesti Oil Field became unavailable. What I question is how Zero Petroleum's product has become a 'wonder' fuel. There's nothing wonderful about it. It requires prodigious quantities of electricity to produce. How is it then 'zero carbon' given that other than UK nuclear generation (with decommissioning removing a lot of it very soon), the next big chunk is generated by burning natural gas?

And what has this to do with the RAF anyway? Zero may or may not be able to produce synthetic aviation fuel that can eventually compete in the open market. The UK may eventually wake up to the urgent need to get more nuclear generation on line ASAP. Then we can all wallow in the limitless 'free' electricity promised us all in the fifties. In the meantime we'll be lucky to keep the lights burning, let alone support energy heavy synthetic fuel production, zero C or otherwise. Zero fuelled up a light SE GA a/c with a few gallons of their 'wonder zero carbon' fuel and got the DT to run this promotional piece, and the RAF clambered aboard to give it the 'air of authority' it sought. Well done Zero! Null points everyone else!
