What are the extreme uses of environmentally friendly fuels?

Restaurant kitchens and industrial boilers use environmentally friendly fuels for cooking. There is also a new energy vehicle fuel on the market, which contains methanol and an alcoholic gasoline. Can be used in cars, but long-term use consumes a lot and has an impact on the engine. At present, a new generation of environmentally-friendly fuel is high-energy polymer oil, which cannot be ignited with open flame and is not dangerous. High-energy polymer oil has a high calorific value, which is more than 4 times higher than the flame resistance of this alcohol fuel.
