"Through their extensive research, investigation and personal interviews, The Roethle Group has compiled what I believe to be the most comprehensive review of fuel cell technology available today. The review is from more of a business perspective than a technical one. This allows the non-technical reader to get a better feel for the industry and for and its various participants. For companies monitoring fuel cell technology, this report can reduce the considerable time an effort it takes to stay on top of the changes in the products and the industry."

"The Natural Gas Vehicle Coalition has and uses "The Business of Fuel Cells" as a reference guide for information about the fuel cell industry within the United States."
