Biomass Plant Powered by Clean Energy Systems

Clean Energy Systems (CES) has purchased an idle six-MW biomass power plant near Bakersfield, California. Along with that transaction, CES entered into a long-term lease for approximately 37 acres at the site. The company plans to re-power the plant initially with natural gas as a fuel, to generate steam using its recently tested ‘zero-emission’ electric power generation system.

Rancho Cordova – August 12, 2003 [] CES said they plan to use the Kimberlina Power Plant to demonstrate the company’s patented technologies and associated system components as they become available. According to CES, their gas generator technology enables the generation of electric power without pollution. The system emits no nitrogen oxide, sulfur dioxide, particulate matter or any of the other harmful elements often associated with conventional power systems, CES stated. “Initial efforts will focus on the CES gas generator system operating on natural gas and the use of conventional steam turbines for power generation,” said Keith Pronske, CEO of Clean Energy Systems. “Future work will include demonstration of advanced, higher temperature, more efficient turbines, and could include the use of gasified biomass as a fuel.” CES views the re-powered plant as an ideal site for the development of the company’s technologies, because of the existing infrastructure, availability of water and multiple fuels, and close proximity to gas and oil fields, which can beneficially use the carbon dioxide captured in the power generation process. The power plant was purchased from a wholly-owned subsidiary of the AES Corporation, an independent power producer with more than 55,000 MW in 28 countries. As a result of this transaction, AES will have a minority ownership position in CES. The gas generator technology is derived from the aerospace industry and results from more than eight years of effort by a team led by experienced aerospace scientists and engineers. Successful testing of a commercial scale gas generator was completed in February 2003. The gas generator, which replaces the boiler in a conventional power plant, can combine any one of a range of alternative fuels with oxygen and cooling water to produce a working fluid of steam and carbon dioxide (CO2). This working fluid drives turbines, which generate electricity. The steam is then cooled in a condenser to a liquid water state, and the CO2 is extracted as a gas for conditioning for sale or other disposition. The CES technology offers the power industry the most cost-effective means of 100 percent CO2 separation and capture. The gas generator was manufactured to develop advanced power generation systems and was built and tested under the Vision 21 Program of the U. S, Department of Energy (DOE). DOE’s National Energy Technology Laboratory (NETL) funded 67 percent of the $3.6 million project. CES is also currently developing a small, near-zero emissions demonstration power plant, with the participation of the California Energy Commission, America Air Liquide, and the Mirant Corporation. In July 2003, the Norwegian Oil and Energy Department (OED) indicated that CES and partners, led by CO2-Norway, have been selected for partial funding to study the “Zero Emission Norwegian Gas” (ZENG) Project. Clean Energy Systems, CO2 Norway, Lyse Energi AS, and the Energy Park in Stavanger, Norway proposed this project.
