Hybrid Power: A 2003 Perspective for the Decade

Abstract

Hybrid power generation systems are evolving as attractive candidates for high-efficiency production of electric energy and a near-zero emission of primary pollutants. Hybrids, by definition, are a combination of two or more power generation technologies that create a synergistic value greater than the sum of the individual parts. Examples include fuel cells integrated with gas turbines, fuel cells integrated with photovoltaics, and heat engines integrated with wind generation. This paper describes the evolution of hybrid systems for both distributed power generation and central power generation as anticipated for this decade, the development requirements and application opportunities, and strategies that utilize both fossil and renewable fuels to achieve the dramatic increase in electrical efficiency that hybrid systems portend.
