NASA has been involved in evaluating the need for such technology and continues to pursue it through SBIR-sponsored and other programs. As a result there are numerous applications that can benefit from this technology, including but not limited to,engines for prime propulsion, auxiliary power, and power generation where higher performance and lower exhaust emissions are desired. Large frame power generating gas turbine manufacturers such as Honeywell, United Technologies, Rolls-Royce, General Electric, and Siemens are in need of this technology for their low-emission combustion systems and the market for such a proven device is world-wide. NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
