CPS COMPANY HISTORY
CPS was among the founders of the cogeneration and independent power business in California. Research and development on Cheng Cycle® power generation technologies began in 1974 and continues to present day. Dr, Dah Yu Cheng founded International Power Technology (IPT) in 1974. In 1994, Dr. Cheng incorporated CPS to focus his research efforts on steam injection for power augmentation in large industrial and aero-derivative combustion turbines and on developing an improved Advanced Cheng Cycle®. In 1982, began the commercialization of a promising, advanced technology for steam injection of gas turbines. The "Cheng Cycle®", is ideally suited for small to large sized industrial and institutional cogeneration customers. Venture capital investors recognized the potential of the Cheng Cycle® and provided the capital necessary to build CPS into a successful company. The company raised an “A” round of venture capital funding by selling preferred stock to Hartford Steam Boiler Capital Corporation and also secured debt financing from Calpine Corporation and Hartford Steam Boiler. In 2001, CPS raised a “B” round of funding by selling preferred stock to Mirant Capital Corporation and Sawmill Capital Corporation. At that time, Calpine and Hartford Steam Boiler converted their debt to additional equity.
CPS (including Dr. Dah Yu Cheng acting as an individual and predecessor and related companies owned by Dr. Cheng) have been engaged in steam injection research since the 1970’s. Dr. Cheng’s first major success came in 1984 with the commercialization of the Allison 501-KH Cheng Cycle® plant at San Jose State University in San Jose, California. That plant was built with State of California support, is still in operation, and has been a significant commercial success. Today, more than 130 Allison (Rolls Royce and now Seimens) 501-KH and Kawasaki M1A-13CC Cheng Cycle® engines are in commercial operation around the world. The installed base of Cheng Cycle® plants has nearly 3 million hours of operational experience
Experiments with advanced steam injection techniques for large combustion turbines led Dr. Cheng to notice some unexplained phenomenon related to NOx emissions. This led to a research program on using advanced steam injection techniques to control NOx, and it was this research program that led to the development of the CLN® technology. In 2000, CPS constructed an atmospheric combustion hardware test facility at IPT’s Allison 501KH Cheng Cycle® cogeneration plant in Menlo Park, California to specifically investigate and develop the CLN® technology. This location was chosen so that the Cheng Cycle® plant could provide steam, water, fuel and electricity to the test rig. Early experimental results confirmed that, with proper nozzle design and steam and fuel mixing, it was possible to increase steam-to-fuel ratios to well beyond the conventional state-of-the-art and that steam-to-fuel ratios in excess of 3 to 1 would yield very low NOx levels without increasing CO, THC or VOC levels. Focus shifted to testing actual engine hardware, and over the course of about a year, comprehensive testing was performed on GE Frame 5N, Frame 5P, Frame 6B, Frame 7B, and Frame 7EA, and on Westinghouse 501-D5A combustion turbine hardware. Exhaustive amounts of data were collected and detailed analyses and test reports were prepared. Test results for the combustion turbine hardware testing clearly shows that low single-digit NOx levels with steam-to-fuel ratios as high as 4 to 1 were achieved. CPS employed EPA-certified emissions testing laboratories to obtain independent third-party measurements of combustion turbine hardware test emissions levels (reference projects page).
In 1983 CPS co-developed the Allison 501-KH steam injected gas turbine with Detroit Diesel Allison in Indianapolis, Indiana and Allison subsequently named the new 501-KH gas turbine the “Cheng Cycle” in honor of its inventor Dr. Dah Yu Cheng. In 1984 the first commercial Cheng Cycle® was installed at San Jose State University located in San Jose California and is still operational today.
Most in the cogeneration and independent power business are familiar with CPS’ Cheng Cycle® activities. CPS strives for innovation and effort to perfect its technology development company to an energy service company. The design of the Cheng Cycle® system was largely refined and standardized over the first six installations. By 1987 commercialization was complete, marketing, sales, and packaging activities were licensed out to selected manufacturing and engineering companies. A worldwide network was thus established with licensees in Ohio, Japan, Western Europe and Australia. CPS provides design, startup and operating services to licensees of Cheng Cycle® technology. There are now 135 Cheng Cycle® units worldwide using the 501-KHX technology and more than 300 Cheng Cycle® power plants worldwide in operation.
