Concept: produce pellets from abundant biomass. This is a multi-billion dollar market local economy option, and can get major buy-in from any community development organization. It is carbon neutral in the traditional sense, and carbon negative if pellets are turned to biochar for agricultural practices. A turnkey system would consist of:
- Hammermill/chopper for taking in any source of biomass. minor hammermilling is required with straw or hay feedstock
- Pelletizer. If automated, agricultural residue comes in on one side, pellets come out the other.
- Char maker - produces char pellets
- Gasoline engine - runs on char gas via a gasifier
This simple device is equivalent to exxon megarefineries, and is environmentally much more sound.
The key is using pellets instead of wood chips - which are highly flowable and allow for system size much smaller than log or chip fired systems.
Sawdust can be used, but is not necessary.
