Stirling Energy Systems (SES) dish-Stirling program

This paper describes a system to produce electrical power from the Sun, and the plans for preparing it for commercial operation. The point-focus, Stirling engine-based system was designed and tested in the 1980s by McDonnell Douglas Corporation and United Stirling AB of Sweden (now part of Kockums AB). Stirling Energy Systems (SES) has acquired the existing hardware and technology, and plans to upgrade the system in order to utilize its demonstrated performance to produce grid-compatible electrical power. The performance includes a higher solar-to-electric conversion efficiency than any other renewable energy technology (approximately 30%), with the potential of a two to four point increase. The paper presents a summary description of the hardware, its past test program, proposed improvements and the plan for commercialization.
