Fats from thin air: Startup makes butter using CO2 and water

Bill Gates has thrown his weight – and his money – behind a Californian startup that believes it can make a rich, fatty spread akin to butter, using just carbon dioxide and hydrogen. And 'butter' is just the start, with milk, ice-cream, cheese, meat and tropical oils also in development.

The San Jose company, Savor, uses a thermochemical process to create its animal-like fat, which is free of the environmental footprint of both the dairy industry and plant-based alternatives.

"They started with the fact that all fats are made of varying chains of carbon and hydrogen atoms," Gates wrote in a blog post. "Then they set out to make those same carbon and hydrogen chains – without involving animals or plants. They ultimately developed a process that involves taking carbon dioxide from the air and hydrogen from water, heating them up, and oxidizing them to trigger the separation of fatty acids and then the formulation of fat."

Many of us know the stats – according to the United Nations Food and Agriculture Organization (FAO), livestock are responsible for 14.5% of all global greenhouse gas emissions, and animal-fat alternatives that use palm oil contribute to widespread deforestation and biodiversity loss – but also know how delicious dairy products are. So will Gates' enthusiastic support be enough to get people excited about butter made from CO2?

Probably give you bad gas. I don’t need any help there.
