This ringbound book provides a reproduction of the Hydrogen, Fuel Cells, and Infrastructure Technologies Program, Multi-Year Research, Development, and Demonstration Plan through 2015, prepared for the Office of Energy Efficiency and Renewable Energy of the U.S. Department of Energy. It features hundreds of detailed tables, charts, and graphs. Developing hydrogen as a major energy carrier will require a combination of technological breakthroughs, market acceptance, and large investments in infrastructure. Success will be incremental over decades; and it will require an evolutionary process that phases hydrogen in, assisted by government policies, as the technologies and their markets mature. Early market and niche applications (e.g., forklifts, stationary and portable power) can help pave the way for automotive fuel cells by accelerating development of manufacturing capability and facilitating customer acceptance. The successful development of hydrogen energy from diverse domestic resources will ensure that the United States has an abundant, reliable, and affordable supply of clean energy to maintain the nation s prosperity throughout the 21st Century. The central mission of the Hydrogen Program is to research, develop, and validate hydrogen production, delivery, storage, and fuel cell technologies. Development of hydrogen as an energy carrier from diverse domestic resources will ensure that the United States has an abundant, reliable, and affordable supply of clean energy to maintain the nation s prosperity throughout the 21st century. The current focus of the Hydrogen Program is on addressing key technical challenges (for fuel cells and hydrogen production, delivery, and storage) and institutional barriers (such as hydrogen codes and standards to maximize safety, training, and public awareness). The Program is currently conducting basic and applied research, technology development and learning demonstrations, as well as safety research, systems analysis, and public outreach and education activities. These activities include cost-shared, public-private partnerships to address the high-risk, critical technology barriers preventing widespread use of hydrogen as an energy carrier. Public and private partners include automotive and power equipment manufacturers, energy and chemical companies, electric and natural gas utilities, building designers, standards development organizations, other Federal agencies, state government agencies, universities, national laboratories, and other national and international stakeholder organizations. The Hydrogen Program encourages the formation of collaborative partnerships to conduct RD&D and other activities that support Program goals. The Program addresses the development of hydrogen energy systems for transportation, stationary power, and portable power applications. Transportation applications include fuel cell vehicles and hydrogen refueling infrastructure. Hydrogen used for back-up emergency power and residential electric power generation is included in stationary power applications. Consumer electronics such as cellular phones, hand-held computers, radios, and laptop computers are among portable power applications. The Department of Energy (DOE) is funding RD&D efforts that will provide the basis for the near-, mid-, and long-term production, delivery, storage, and use of hydrogen derived from diverse energy sources, including fossil fuel, nuclear energy, and renewable sources. This document describes the status, challenges, and RD&D activities of the DOE program. Contents include: Program Vision * Hydrogen, Fuel Cells and Infrastructure Technologies Program Key Activities * Program Planning * Scope of Multi-Year RD&D Plan * Program Evaluation * Program Coordination * Transformation to a New Energy System * Program Benefits * U.S. Transportation Energy Challenges * Potential Impa
