SR/OIAF-CNEAF/2008-04 The Impact of Increased Use of Hydrogen on Petroleum Consumption and Carbon Dioxide Emissions September 2008 Energy Information Administration Office of Integrated Analysis and Forecasting Office of Coal, Nuclear, Electric and Alternate Fuels U.S. Department of Energy Washington, DC 20585 This report was prepared by the Energy Information Administration, the independent statistical and analytical agency within the Department of Energy. Unless referenced otherwise, the information contained herein should be attributed to the Energy Information Administration and should not be construed as advocating or reflecting any policy position of the Department of Energy or any other organization. Service Reports are prepared by the Energy Information Administration upon special request and are based on assumptions specified by the requester. Preface and Contacts The Energy Information Administration (EIA) is the independent statistical and analytical agency within the U.S. Department of Energy. EIA provides timely, high-quality energy information and prepares objective, transparent analyses for use by the Congress, the Administration, and the public. EIA does not, however, take positions on policy issues. Because of EIA’s statutory independence with respect to the content of its energy information program, the analysis presented herein is strictly its own and should not be construed as representing the views of the Department of Energy or the Administration. The model projections in this report are not statements of what will happen but of what might happen, given the assumptions and methodologies used. EIA does not propose, advocate, or speculate on future legislative and regulatory changes. All laws are assumed to remain as currently enacted; however, the impacts of scheduled regulatory changes, when defined, are reflected. EIA’s Office of Integrated Analysis and Forecasting (OIAF) and Office of Coal, Nuclear, Electric and Alternate Fuels (CNEAF) prepared this report.
