Optimal Biomass on Left = Blue, Red
Load centers = Green
Biomass technology converts bio-based feedstocks like wood, agricultural waste, and yard waste through combustion into electricity. Biomass fuel is either directly combusted in a boiler, or gasified and then combusted, or turned into a liquid fuel that can be combusted. The ...
