The basis of DG’s integrated fuel and energy technology is the proven Fischer Tropsch process, in use for over 60 years. Existing plants around the world produce over 170,000 BBL per day of synthetic fuel using Fischer Tropsch. These facilities typically use approximately one ton of coal to produce one BBL of hydrocarbons, with a life cycle CO2- emissions calculation that is slightly worse than equivalent fuels derived from conventional oil refining.
DGE’s method modifies the established Fischer Tropsch system with several mechanisms that will decrease the CO2- life-cycle emissions and reduce the quantity of feed-stock required. These changes eliminate the need for carbon sequestration and reduce the system’s feed-stock handling costs and complexity.
The feed-stock reduction is achieved primarily by supplementing the process with oxygen and hydrogen produced by water electrolysis units that are powered by clean wind and solar generated electricity. DGE replaces the coal gasification used by others with biomass gasification and natural gas reforming. This simplifies implementation and further reduces new carbon emissions created in the process.
The DGE produced fuels, though technically identical to the final hydrocarbon products produced by others, will have a life-cycle CO2- emissions calculation that is 65% lower than that of comparable products refined from conventional petroleum.
