Prior to that event, DOE asked the National Research Council to examine key technical issues about the hydrogen economy to assist in the development of its hydrogen R&D program. Included in the assessment were the current state of technology; future cost estimates; CO2 emissions; distribution, storage, and end use considerations; and the DOE RD&D program. The report provides an assessment of hydrogen as a fuel in the nation\u2019s future energy economy and describes a number of important challenges that must be overcome if it is to make a major energy contribution. Topics covered include the hydrogen end-use technologies, transportation, hydrogen production technologies, and transition issues for hydrogen in vehicles.\n\n", url = "https://nap.nationalacademies.org/catalog/10922/the-hydrogen-economy-opportunities-costs-barriers-and-rd-needs", year = 2004, publisher = "The National Academies Press", address = "Washington, DC" }
