It’s an ingredient that’s already been used to make vodka. Not potatoes – but the gas responsible for global warming.
A Swiss-based start-up is using clean energy to extract CO2 from the air already. The aviation industry accounts for 3% of all CO2 emissions worldwide.
Since battery-operated airplanes won’t take to the skies on the fly, the industry is working to produce sustainable fuels (so-called SAFs), with a pilot project already underway in Rotterdam.
After adding water the extracted CO2 is first turned into synthetic gas by means of electrolysis. Next a reactor transforms the syngas into liquid hydrocarbons which are refined for use as aviation fuel.
Subsequent CO2 emissions during flying could be turned back into fuel.
