Various types of fuel cells are being proposed for almost every electrical power generation application, from portable electronics to motor vehicles to stationary power generation at every scale. Yet, despite great technological progress and billions of dollars of private and public sector investment, no great fuel cell "success stories" have yet emerged. This presentation will 1) briefly review the present state of fuel cell technology and market development in the mobile and stationary sectors; and 2) review the results of recent economic analysis conducted by the speaker and his collaborators of a few examples of potential innovative applications of proton-exchange membrane (PEM) fuel cell technology. These examples focus on potential synergies between uses of fuel cells in the motor vehicle and stationary sectors, including: 1) "hydrogen energy stations" that would co-produce electricity for local loads and/or the grid as well as pure hydrogen to re-fuel FCVs (using a common stationary fuel cell/natural gas reformer system); and 2) the possibility of using FCVs and other types of electric-drive vehicles to supply electricity and/or electricity market ancillary services to electrical grids.Dr. Timothy Lipman completed a two-year post-doctoral research fellowship with the Energy and Resources Group (ERG) at UC Berkeley in September of 2002. He is currently working as a private consultant to the Union of Concerned Scientists and the Natural Resources Defense Council, and he plans to rejoin UC Berkeley in January of 2003 as a research engineer and as executive director of the new California Institute of Distributed Energy Research (CIDER). While at UC Berkeley, Dr. Lipman led a research program under Prof. Dan Kammen's Renewable and Appropriate Energy Lab (RAEL) that conducted various projects to examine the economics and environmental impacts of using fuel cells and other clean energy technologies as distributed power-generating resources.Dr. Lipman completed a Ph.D. degree in Environmental Policy Analysis with the Graduate Group in Ecology at the University of California at Davis, in December of 1999. He then served as Associate Director of the Fuel Cell Vehicle Center at the Institute of Transportation Studies at UC Davis through August, of 2000. Dr. Lipman also completed an M.S. degree in 1998 in the technology track of the UC Davis Graduate Group in Transportation Technology and Policy, and a B.A. in 1990 from Stanford University in Anthropology.
