GreatPoint Energy, Inc. is a technology-focused company that specializes in producing pure hydrogen and substitute natural gas using its proprietary catalytic hydromethanation process. This innovative technology converts carbon-rich feedstocks, including coal, petroleum coke, and biomass, into a methane-rich gas stream, facilitating the creation of low-cost, clean gas suitable for various applications. The company's products serve residential and commercial heating, power generation, industrial processes, and chemical production, while also enabling near-zero carbon electricity generation. In addition to its primary outputs, GreatPoint Energy's process yields valuable by-products such as vanadium, nickel, activated carbon, ammonia, and sulfuric acid. Founded in 2004 and headquartered in Cambridge, Massachusetts, the company caters to clients in several countries, including China, South Korea, Japan, Taiwan, and Indonesia, while collaborating with strategic partners such as AES Corp, Dow Chemical, Peabody Energy, and Suncor Energy.

CoalTek, Inc. specializes in the production of high-quality coal by converting lower-grade coal into a cleaner energy fuel with reduced environmental impact. Founded in 1998 and headquartered in Tucker, Georgia, the company employs a proprietary volumetric heating process that targets moisture within the coal, utilizing 50-70 percent less energy compared to traditional thermal methods. This technology, developed over eight years by co-founder Dr. Jerry Weinberg and chief geologist Neil Ginther, effectively reduces the moisture content in various types of coal, enhancing plant efficiency and ensuring compliance with environmental standards. CoalTek opened its first commercial processing facility in Calvert City, Kentucky, in 2006, with an initial capacity of 120,000 tons per year, and plans for future expansions and additional facilities to meet the increasing demand for clean coal solutions.
