The description in the article says these are fatty acid methyl esters, mostly from animal fat.
That means 12 to 18 carbons on each of the 3 chains, plus the 3 carbons on the glyceryl backbone.
That's a lot of carbon. Know what carbon gives us? CO2. Yeah, the biggest culprit in climate change.
I understand the excitement of sustainability & weaning off petroleum.
But, given the energy density of esters vs. kerosene, I'm not seeing the climate change benefit.
The article references "decarbonization". Using carbon to replace carbon is not decarbonization.
