So how it works is they have specially bred or engineered microorganisms (usually bacteria, yeast, or algae) in fermentation vats. There's been a lot of these startups, going back 10-20 years at least. They can get sugars, proteins, alcohols, oils, or even hormones like insulin, depending on the gene expression. Many have been focused on biofuels for engines and heating. This startup is hydrogenating the oil into margarine. Technically they pull carbon from the air, and hydrogen can be sourced either from water or fossil fuels. It takes a lot of energy to make that into hydrocarbons.
