Woody Biomass
Dead, diseased trees, brush, slash piles from local forests and private lands.
Feedstock prep
Woody biomass is chopped, dried, blended for consistency and fed to the gasifier.
gasification
Feedstock is gasified at high temps to produce synthesis gas. The syngas is purified and reformed to produce carbon monoxide and hydrogen gases.
Converting Syngas to Liquid Fuel
Via Fischer–Tropsch chemical reaction processes, the syngas is transformed into a waxy paraffinic liquid fuel.
Hydrotreating
In the final stage, the paraffinic wax is stripped to produce a zero sulfur, high cetane synthetic diesel fuel.
Dead & diseased trees in the BLACK HILLS
Forest waste is delivered to the plant
Woody biomass is sized, fluffed & blended
Feedstock is fed to gasifier at high temps to produce syngas
Syngas is purified and reformed to remove impurities
Transformation to liquid fuel via GTL; then hydrotreated and refined
Advanced synthetic diesel is transported via rail to CA
Sold in California to maximize renewables credits
