into other chemicals like ammonia, dimethyl ether, and synthetic hydrocarbons, supporting diverse industrial applications. By producing low to negative carbon intensity fuels, SunGas significantly reduces carbon emissions, contributing to global efforts to combat climate change. For example, the S1000 technology, coupled with carbon capture and sequestration, can produce advanced fuels with deeply negative carbon intensity from -60 to -100 gCO 2 e/MJ of fuel. Pioneering facility for sustainable fuel production SunGas’ Beaver Lake Renewable Energy (BLRE) facility in Central Louisiana will convert ~1 million tons of dried wood residue into more than 500,000 metric tons of bio-methanol annually, marking a significant contribution to sustainable energy production. This $2 billion facility will be built at the former International Paper site in Rapides Parish, expected to create more than 1,100 construction jobs, 300-400 indirect jobs, and 100 full-time jobs to the local economy. The renewable methanol produced at the facility is slated to be used primarily as a marine fuel but may also be used as a low-carbon feedstock for SAF and renewable dimethyl ether (rDME). Renewable DME is a drop-in fuel that can decarbonise the carbon footprint associated with the use of propane. Figure 6 provides a visual summary of the project scope. In 2024, SunGas announced a strategic partnership with C2X aimed at developing, owning and operating multiple green fuel production facilities in North America to increase the supply of sustainable fuels and advance global decarbonisation of hard- to-abate industries like aviation and marine shipping. SunGas’ focus on advanced clean fuels supports local economies by creating jobs, attracting new investments, and supporting sustainable and resilient technology development. Prospects and opportunities SunGas envisions a promising future, driven by strategic partnerships and innovative technologies. SunGas has already put its strong

logistics are already established in the industry and readily leveraged to improve the feedstock economics. Syngas conversion to clean fuels Syngas, a mixture of hydrogen, carbon monoxide, and carbon dioxide, has been converted into various valuable products for decades. For renewable natural gas (RNG), syngas undergoes methanation, where hydrogen and carbon monoxide react to form methane and water. To produce hydrogen, syngas is subjected to a water-gas shift reaction, increasing the hydrogen content. For methanol production, syngas is catalytically converted into methanol through reactions involving hydrogen and carbon monoxide. To produce SAF, naphtha, and/or diesel, the Fischer-Tropsch process is an established pathway. Additionally, syngas can be processed Figure 5 S1000: an integrated gasification system for syngas production from woody biomass
