Startup Makes Butter Using CO2 and Water (newatlas.com) 206
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.

If it's cheaper than butter, then I might be interested; there's been a vegan alternative to butter promoted in the UK recently that did taste good, but it wasn't especially cheap. Though the definition of 'cheaper' does deserve hard questions; how far is the normal production of butter subsidised by the production of pollution that isn't being paid for.

The problem with ultra-processed food is usually not the ultra-processed food, .but the lack of un- or low-processed food.
Furthermore, the issues with that "ultra-processed" food category are wide and varied in itself. Some items have high sugar or fat, some have lower fiber than the stuff it is supposed to replace, some have indeed additives that don't become a problem until they are in everything you eat and adding up to critical levels. Some stuff in that category isn't even that highly processed at all! Engineer together low processed Salt, Fat and Sugar and a few flavors and you have something that should NOT be your sole diet, but triggers all addiction centers in your brain: Cookies
And there is nothing wrong with cookies but they still should not be the only thing you eat.
That "ultra-processed-food" thing is a rule of thumb. And as long as 95% of food engineering effort goes into making food cheaper at lower qualities, it is an absolutely valid rule of thumb. Would be different if the goal of that whole processing would be high quality food. Food does not HAVE TO be bad just because it is produced in a big factory, but it usually is.

Fats are generally much simpler than, say, a whole strawberry. And if you're looking for "microbiologically safe", a synthetic product stream is FAR less likely to be contaminated by bacteria than something sourced from dirty cow udders.
Producing food from air or organic waste was something I started thinking a lot about during the Assad sieges on Syrian rebel strongholds, when people were starving - not that it would have been practical for them to implement on the fly, but you know, could it be done at all? You can get to the same sorts of syngas either from CO2 + water + energy, or wood gas.
Glycerol is probably the simplest abiotic calorie source, maybe via the acrolein/propylene oxide route; both should be produceable from your syngas either in directly or in a few-step process.
But you don't just need calories. Producing mixed carboxylic acids (fatty acids) isn't too hard (selective oxidation of syngas hydrocarbons), but selecting just the ones that are healthy to consume (including essential fatty acids), and better, joining them into triglycerides with the above glycerin so that they're not disgusting, definitely dials up the complexity. You could probably chain the glycerin and carboxylic acid processes together using different fractions of the gas-to-liquids product for each.
You're not going to be assembling whole proteins from scratch. Individual amino acids are possible and perfectly edible, though challenging, and there's at least nine that you have to synthesize. And then there's a whole host of vitamins that one needs in ever-smaller quantities.
The motivation would, of course, be the potential for less input energy requirements and vastly less input space, in constrained environments (not just edge cases like cities under siege from a dictator, but places like space habitats). I don't think you'd realistically ever justify using non-biological processes for anything needed in the quantities of amino acids or less; I think in any situation it would just be better to leave that to microbes. But getting calories and essential fatty acids from synthesis, that seems plausible.

While Germans were using coal as the source of carbon and this Bill Gates funded effort is using CO2 the chemical process is much the same. I suspect that this new variation on the theme of "coal butter" would be quite energy intensive because they are starting with carbon that's already been oxidized as opposed to carbon that is not oxidized in the form of coal. This energy has to come from somewhere. In the case of butter from dairy cows the energy comes from plants that the cattle have eaten, so it's solar powered. Bill Gates says this process "uses no farmland" but if it's using solar power then it is still using land, and depending on the specifics it could be using more or less land. It could also be using a lot of water because solar panels need to be washed and cooled. It could be using a lot of toxic chemicals because those solar panels are made from something. I'm not so sure this would be environmentally beneficial.
