TDA Research was formed in 1987 by two staff from the Solar Energy Research Institute (now the National Renewable Energy Laboratory) in Golden, CO. Since that time, TDA has grown to a staff of 84 with annual revenues of approximately $11.6 million. TDA is a privately held R&D company which develops new materials (polymers, carbons and ceramics), catalytic and sorbent-based chemical processes and military and aerospace components, we bring them to market either by forming internal business units, or more frequently, in partnership with larger Global 2000 manufacturing companies. TDA's Direct Oxidation Technology removes sulfur from hydrocarbon streams, our fullerene production technology is used by Frontier Carbon to manufacture up to 40 tons per year of fullerenes, and our processable conducting polymers are available from Sigma-Aldrich.
