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 think it's closer to the coal butter synthesis but maybe they found a more efficient method using other carbon sources

The process required at least 60 kilograms of coal per kilogram of synthetic butter.
