      Today, approximately 15% of the world’s production of vanillin is still made from lignin wastes,[11] while approximately 85% is synthesized in a two-step process from the petrochemical precursors guaiacol and glyoxylic acid.[12][13]

            As atomicbocks points out, a major obstacle for sustainable fuels for combustion engines is that there isn’t enough biomass around. Also why the new sustainable ship engines run on ammonia.

            Yes, we have even made bacteria that excretes fuels. But nothing that competes with just pulling hydrocarbons out of the ground at scale like we have with diamonds.

            The main scaling issue is that the constituent carbon still has to come from somewhere, and one of the main carbon sources we have is… oil.

            The best solution is to move away from carbon based fuels.
