I am starting to see something that hasnt been around for awhile and that is renewable alternative fuels starting to nose back into the press. OPEC finally looks like its going to actively defend $100 a barrel and that means the economics of biofuels start to match up with oil. The propane association is pushing renewable propane (uses the same basestock as biodiesel). The Renewable Fuel Oil product that I worked with several years ago is looking at building a plant in the US (East Millinocket Maine) https://www.bangordailynews.com/202...wood-east-millinocket-biorefinery-joam40zk0w/ and some other tech is being dusted off. I recently saw a plug for Ethyl Levulinate (broken link removed) . I dont see biodiesel being much of player as to date it depends on unsistainable Palm Oil plantations in Indonesia. The EU long ago banned palm oil based biodiesel so currently is going elsewhere. The Ensyn product is made from forestry and sawmill scrap (it can be made out of any cellulosic wastes). I think the Ethyl Levulinate fuels are also made from biomass.
All this tech depends on sustained high oil prices or carbon taxes to make it competitive. Once these supplies start getting built locally they will probably buidl a market but a sustained drop in oil prices will kill them.
