Calories

Fat from syngas, cocoa from a vat

Protein gets the headlines. A large share of the calories on a plate are fat — and fat can be chemistry.

Savor, a U.S. start-up named in the New Scientist piece, makes edible fats from syngas: hydrogen plus carbon monoxide. It is a less picturesque story than a field of sunflowers. It is also closer to how a refinery thinks, which is why it might scale.

Elsewhere, the same logic reaches the foods people actually crave. Plant cells — cocoa among them — can be grown in vats, so the molecule that flavors a bar does not require an equatorial tree and a cleared understory. The vat is not romantic. The forest that remains is.

Methane fermentation is the precedent for scale, and the warning for feedstock. Norferm in Norway made 110,000 tonnes of microbial protein for fish food between 1999 and 2005. Calysta’s factory in China is reported around 20,000 tonnes a year. Unibio is building toward about 50,000 tonnes a year in Saudi Arabia. The hardware lesson is settled. The climate lesson is not, as long as the gas is fossil.

Put the routes side by side and the category stops looking like one company’s trick. Hydrogen protein, acetate for yeast and altered plants, syngas fats, cells in tanks, methane if the methane is clean. Electrical agriculture is the name for the whole shelf.

That is also why the exact-match .com matters. The science just acquired a plain-language title. The companies still have product names. The field did not, until the words sat next to each other.
