Frontieras signs LOI for two coal-conversion plants on Mississippi
Frontieras North America has signed a letter of intent (LOI) with Cora Terminal, a joint venture between Watco Companies and SCH Services, to develop up to two FASForm solid carbon fractionation plants at the Cora Terminal in Rockwood, Illinois. The agreement marks Frontieras' third announced commercial site and its first in the Midwest, following a reported $850 million first facility currently under construction in Mason County, West Virginia.
Under the terms contemplated by the LOI, Frontieras would initially lease approximately 85 acres for a first plant, with an option to expand to around 130 acres for a second. Each plant is designed to process 7,500 tonnes of coal feedstock per day on a continuous basis. At full two-plant scale, the site would receive approximately 5.5 million net tonnes of Illinois Basin coal annually by unit train, dispatching outbound products by barge, rail and truck.
What FASForm does
FASForm is a patented thermal process that disassembles coal in a reducing atmosphere, without combustion, yielding a slate of products including FASCarbon (a thermal coke), ultra-low-sulfur diesel (ULSD), jet fuel, naphtha, hydrogen-rich gas, sulfuric acid and ammonium sulfate fertiliser. Because the process involves no direct burning, the company says it produces no direct carbon dioxide at the point of conversion and reduces sulphur oxide emissions by approximately 97% relative to conventional coal combustion.
Those claims are material but unverified by a named third party. Frontieras describes itself as a development-stage enterprise that recently completed a Regulation A+ public offering, a smaller-scale equity raise available to earlier-stage US companies. Its first commercial plant in West Virginia remains under construction, with no commercial operating history reported.
Chief commercial officer Andrea Moran said: "Cora has everything FASForm needs: rail, barge, bulk handling, and Illinois Basin coal in one place, as one of the best-positioned industrial sites on the inland waterway system."
Market and policy context
The story sits at an unusual intersection in the energy transition: a coal-feedstock process positioned by its developer as low-emission industrial chemistry rather than power generation. The technology competes with, and in some respects overlaps, established coal-to-liquids and coal gasification processes, as well as emerging carbon capture and utilisation pathways. The sector is thinly capitalised outside of state-backed programmes in China and India, and faces a structurally declining coal feedstock market in the United States.
From a policy standpoint, US incentive frameworks are ambiguous for this category. Clean fuel production credits under the Inflation Reduction Act's 45Z provision are tied to lifecycle carbon-intensity scores, and whether a coal-derived ULSD or jet fuel would qualify depends on independent lifecycle analysis that Frontieras has not yet disclosed publicly. Environmental permitting in Illinois will be a critical gate; any facility of this scale, processing millions of tonnes of coal annually, will require rigorous air-quality and water assessments.
The LOI itself carries no binding financial commitment. Definitive agreements remain subject to due diligence, permitting, project financing and regulatory approvals. The company has not disclosed cost estimates for the Cora build, nor a timeline to financial close or commercial operation. Investors and potential offtake partners will look for a named project lender, a finalised permitting pathway and a commercially verified emissions profile as the key milestones before the project can be regarded as commercially de-risked.
