Farm biochar flowchart
I am hopeful that small affordable energy recovery pyrolysis systems are on the way so that this farm scenario can have an 'off-grid' energy loop as well. There are a number of interesting alternative energy systems (other than internal combustion) at various stages of development. Some could use the waste heat from pyrolysis and others, the syngas or bio-oil...
- fuel cell (example... Bloom Energy)
- external combustion
- heat pumps
- organic rankin cycle (Turboden)
