Stranger - fully agree. Yet there are so many “science proposals” and many get funded without active criticism from the scientific community.
Hog fuel to anything useful is usually hog wash. First of all it is energy intensive to collect hog fuel - because it is lying all around and it gets mixed with dirt, stones etc. Next transporting hog fuel is a huge endeavor and probably takes more energy than the hog fuel contains. This is because hog fuel is very low density and contains about 50 percent water. Next once it reaches the plant, it has to be cleaned. Then it has to cut to small pieces. Then it has to be dried - taking more energy. When you dry biomass, it gives off volatile compounds that need their own treatment system. Even when dry, their composition changes day to day and the ash is low melting point and clogs up most equipment.
