    it probably makes more sense for the syngas to be directly ignited, rather than sent through a generator, to provide heat for dehydration before pyrolysis
900kg hemp per hectare per season*
400kg of biochar produced by pyrolyzing it
200kg of carbon in that biochar
10000kg of co2 - rough personal annual 'carbon footprint
2730kg of carbon in that co2 to sequester per year 
13.7 hectares or 34 acres
900kg/ha probably involves irrigation and/or fertilizer so might be half that without
