Startup Makes Butter Using CO2 and Water (newatlas.com)

A Californian startup funded by Bill Gates is making rich, fatty “butter” using just carbon dioxide and hydrogen, with other dairy-free alternatives in the works. New Atlas reports: 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.”
“The idea of switching to lab-made fats and oils may seem strange at first,” Gates wrote. “But their potential to significantly reduce our carbon footprint is immense. By harnessing proven technologies and processes, we get one step closer to achieving our climate goals.” Savor’s ‘butter’ is easily produced and scalable, but convincing people to swap out butter and other dairy products for ‘experimental’ foods will remain a challenge for the foreseeable future. Gates is hoping, however, that his support will do more than start a conversation. “The process doesn’t release any greenhouse gases, and it uses no farmland and less than a thousandth of the water that traditional agriculture does,” he added. “And most important, it tastes really good — like the real thing, because chemically it is.”
The research has been published in the journal Nature Sustainability.
