Bill Gates-backed startup makes ‘butter’ out of water and carbon dioxide (www.zmescience.com)

A California-based startup called Savor has figured out a unique way to make a butter alternative that doesn’t involve livestock, plants, or even displacing land. Their butter is produced from synthetic fat made using carbon dioxide and hydrogen, and the best part is —- it tastes just like regular butter.

My thought was "I doubt you can make fat only with hydrogen and carbon", but fats/lipids are literally hydrocarbons. Adding other elements changes the taste, so it isn't necessary to have mammals anywhere in the production chain.

Very interesting and probably not the first time this is/has been done. It seems quite obvious.

It's quite obvious at a theoretical level but not easy in terms of figuring out the actual process. A lot of science like that.

According to the savor team, it was quite easy for them:

“We start with a source of carbon, like carbon dioxide, and use a little bit of heat and hydrogen to form chains which are then blended with oxygen from air to make the fats & oils"

I want to guess they are glossing over a complicated enzyme they created, or other form of reagent.

Yeah, they're definitely glossing over a lot of things. They don't even mention the source of co2 or even a real timeline.

That's like saying you can build a nuclear bomb by smashing pieces of uranium together. Technically true, but it's a lot more complicated than that.
