Frontieras–Western Fuels Dry Fork coal facility: process, products and mine-mouth value...

30 Second Briefing
Frontieras North America and Western Fuels have signed an MOU to build a mine-mouth FASForm coal fractionation facility at the Dry Fork open-pit mine in Wyoming’s Powder River Basin, initially processing up to about 2.7 million tons/year of sub-bituminous coal and potentially 5.4 million tons/year at full build-out. The patented FASForm process disassembles coal in a continuous, closed-loop, zero-waste, reducing atmosphere to produce clean solid carbon (FASCarbon), ultra-low-sulphur diesel, naphtha and other products, with 30-year ground lease, feedstock, diesel offtake and logistics agreements envisaged. FASCarbon could be railed to Western Fuels Association member utilities or exported, positioning the Dry Fork facility within a 1,200 MW mine-mouth generation cluster as a hub for future FASGEN co-location at nearby coal-fired plants.
Technical Brief
- MOU covers a ground lease at or adjacent to Western Fuels’ Dry Fork open-pit mine.
- Each of the ground lease, coal supply, diesel offtake and logistics agreements is envisaged for 30 years.
- Western Fuels will purchase ultra-low-sulphur diesel from the facility for mining, haulage and member operations.
- Western Fuels Association’s existing rail and transport network is expected to move FASForm product streams to market.
- FASCarbon output may be railed under separate commercial terms to WFA member utilities or exported internationally.
- Dry Fork lies eight miles north of Gillette in the Powder River Basin, simplifying short-haul mine-mouth logistics.
- The mine is embedded in a 1,200 MW coal-fired “Gillette mine-mouth generation cluster”, enabling future FASGEN co-location.
- Frontieras views Wyoming’s status as top US coal producer as the anchor for scaling FASForm across western states.
Our Take
In our database, Wyoming coal stories increasingly involve value-added products or critical minerals rather than pure thermal coal, as seen in the Brook mine rare earth and critical-mineral project near Sheridan, signalling a push to keep Powder River Basin assets relevant in a decarbonising power market.
An initial 2.7 Mt/y coal feedstock rising to 5.4 Mt/y at full build-out is material at Powder River Basin scale and, if realised, would help underpin longer-term mine-mouth utilisation around the Gillette generation cluster even if local power demand plateaus.
With coal-to-liquids outputs like diesel and naphtha now appearing alongside coal in our coal-tagged coverage, operators such as Frontieras and Western Fuels are likely positioning for revenue streams less exposed to US power-sector coal retirements and more tied to transport and industrial fuels.
