Distilling doesn't make it more economical than traditional refining though, according to their whole position. Boiling involves ALOT of energy compared to passive membrane separation.

They still have a zero carbon liquid fuel so you can't compare it directly to refined fuel.

Fossil fuels should be eventually taxed into oblivion. Even at current taxation level their distilled fuel would be competitive if tax exempt for example in Europe.

I didn't. The comparison is that this is claimed to be cheaper than normal fuel extraction from the ground. But that relies on tech such as the permiable membrane developed from CNT, which AFAIK, no major breakthroughs have been made.

It's a bit like investment madness, in which investors are being swindled because no one is doing their due diligence to vet the tech and instead throwing money in a blind panic in FOMO.
