Frequently done in Germany. Many farms have built "green humps", that is biogas vats with a green dome-shaped gas collection cover. Those can be fed with manure and any kind of decomposable biomatter, higher nutritional value is of course better. Since green electricity yields high guaranteed prices and gras or maize can be very cheap in some years, those humps are often fed maize and gras.
This is most technical description I could find, other articles frequently focus on the negative effects of resulting monocultures: https://www.vde.com/de/etg/arbeitsgebiete/informationen/biomassekraftwerke https://www.vde.com/de/etg/arbeitsgebiete/informationen/biom...
- specialist 6y agoNeat. We need to capture methane, which is a much more potent green house gas than CO2. Which is not an endorsement of incinerators. I don't know all the whatifs, but I'm hoping incinerators will be replaced, phased out.
- Reason077 6y agoAs far as burning stuff goes, burning biogenic methane is about as good as it gets environmentally. It's a closed loop in carbon terms, and you're reducing GHG emissions by preventing unburnt methane being released into the atmosphere.
