United States Patent Office Grants Tecogen Patent for Catalyst Formulation Used in Ultera Emissions Reduction Process

WALTHAM, Mass., Aug. 14, 2018 (GLOBE NEWSWIRE) -- Tecogen Inc. (NASDAQ: TGEN), a clean energy company providing ultra-efficient, clean, natural gas powered on-site power, heating and cooling equipment, has been granted a US patent for a customized catalyst formulation developed for its Ultera emissions reduction process. The patent covers the material composition and manufacturing method used in its production. This material provides excellent performance while being impervious to corrosion in applications where the engine fuel contains significant contaminants such as sulfur and phosphorus. The material and the manufacturing process were developed under contract with Environex, an independent catalyst testing and development company located in Malvern, PA. In exchange for the know-how and agreement to supply the company with the catalyst, Tecogen has granted Environex a license to use the catalyst formulation other than in internal combustion engines and combined heat and power systems, both under 1,000 kW, for which Tecogen retains exclusive rights. 

Robert Panora, Tecogen’s President and COO, commented, “This is a very important piece of the Ultera technology as many important fuels, including natural gas, gasoline, propane and biofuels have significant impurities which generate corrosive emissions that degrade unprotected emissions control catalysts. The catalyst material developed by Environex is cost competitive and testing over multiple years has demonstrated its effectiveness in extending the longevity of our catalysts.”

Benjamin Locke, Tecogen’s CEO, added, “As we seek broader applications for our Ultera emissions control technology, this patent will provide an additional angle of protection for another key element of the Ultera process and expand our options relative to our commercialization strategy.”

“We are excited to partner with Tecogen in developing a more durable technology to meet the emissions requirements of challenging applications in the IC engine space,” said David Wallace, Environex’s Vice President.
