"This synthetic-fuel startup just got $75 million from Porsche." "The efuel-making process at Haru Oni starts by capturing CO2 from the air and using wind power to electrolyze water into hydrogen and oxygen. The carbon and hydrogen are used to synthesize methanol, and the methanol is then turned into longer hydrocarbons using ExxonMobil's methanol-to-gasoline process."
"Haru Oni's pilot phase (which received $22 million in funding from Porsche) should start producing its first synthetic fuel by mid-year, with a targeted annual production rate of 34,000 gallons (130,000 L) by the end of 2022."
The article has a link to the ExxonMobile website for the methanol-to-gasoline process. I didn't know until now this process existed. Basically it goes from methanol (2 CH3OH) to di-methyl ether (CH3OCH3 + H2O) to "light olefins" + H2O to olefins + CH5 to "parafins, naphthenes, aromatics" to gasoline. You'll have to wait until I have better understanding of chemistry for more of an explanation than that.
They say it gives octane numbers in the 85-90 range. (They give ranges for RON and MON octane numbers. Here in the US, the number at the pump is the average of these. The RON and MON numbers are measurements of how the fuel behaves at low temperature and speeds vs high temperatures and speeds.)
