In a recent proposal, the Off Grid Pro team crunched some numbers and created an infographic, outlining one potential energy model, using non-woody biomass as the material. In this particular case, a horse farmer has a need to handle 3.5 tons of horse manure each day. Additionally, he averages 150kW / day in electrical usage. This model illustrates how that manure can be pelletized and pyrolyzed into gasifier fuel.
Although it doesn’t completely offset his 150kW / day usage, it certainly reduces cost. A 3-gasifier system would cover the total energy needs, with charcoal (biochar) to spare.
