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.

I wonder if they can use CO2 that comes from industrial carbon capture, or if it needs to be something purer that takes a lot of energy to produce.

Also, I'm not sure if we can get industrial volumes of hydrogen from sources other than fossil fuels now. Its been a while, but last I checked it was coming from things like byproducts from reformers.

It would need to be food grade CO2. So breweries would be a good source.
