Biomethane: A Fuel From Pure Grass : MetaEfficient - 0 views
-
In Austria, cars can now fill up on a renewable, locally-produced fuel. The fuel is called “biomethane”, and it’s created by fermenting meadow grass (Poa pratensis). The grass is grown without the input of synthetic fertilizers or pesticides. And it’s a true ‘cellulosic biofuel’ — it doesn’t rely on grains and oilseeds.
