| The hydrogen economy is a proposal for the distribution of energy by using hydrogen. Hydrogen (H2) gives off energy when it is combined with oxygen, but the hydrogen itself has to first be produced, which requires more energy than is released when it is used as a fuel. Some futurists promote hydrogen as potential fuel for motive power (including cars,boats and airplanes), the energy needs of buildings and portable electronics. They believe a hydrogen economy could greatly reduce the emission of carbon dioxide and therefore play a major role in tackling global warming. Countries without oil, but with renewable energy resources, could use a combination of renewable energy and hydrogen instead of fuels derived from petroleum, which are becoming scarcer, to achieve energy independence. In the context of a hydrogen economy, hydrogen is an energy carrier, not a primary energy source. Nevertheless, controversy over the usefulness of a hydrogen economy has been confused by issues of energy sourcing, including fossil fuel use, global warming, and sustainable energy generation. These are all separate issues, although the hydrogen economy affects them all. The report on Hydrogen Economy focuses on the development of a hydrogen economy. Technologies involved in a hydrogen economy, case studies, along with the environmental impact are all discussed in this report. Pages : 89 Publication Date : June, 2009 |

Updates: Whatever Happened to Fuel Cell Progress?
Revving Up Fuel Cells
Progress toward hydrogen-powered cars depends on less expensive but greater capacity fuel-cell systems [see “On the Road to Fuel-Cell Cars”; SciAm, March 2005]. Researchers have taken big steps on both the cost and storage challenges. A team from Quebec came up with a recipe that uses iron instead of expensive platinum to catalyze the electricity-making reaction of hydrogen and oxygen. The key was carbon structures containing microscopic pores, which were filled with iron to provide plenty of active sites for chemical reactions. The iron-based substance, described in the April 3 Science, produced catalytic activity within 10 percent of the best platinum versions and 35 times better than previous, nonprecious metal catalysts.
Pores are also driving the search for materials that can store hydrogen for delivery to fuel cells. A team from the University of Michigan at Ann Arbor says it has made a material that has a record-high surface area for holding gases. This hydrogen sponge consists of zinc oxide clusters linked by an organic material; one gram has the surface area of 5,000 square meters, nearly the size of a football field. Details of the substance, dubbed UMCM-2, appear in the April 1 Journal of the American Chemical Society.

Hydrogen and Fuel Cells in Transportation - the Future is Arriving
Congressional Briefing:
Hydrogen and Fuel Cells in Transportation - the Future is Arriving
Hydrogen and Fuel Cells in Transportation - the Future is Arriving
June 12, 2009, 1-3 pm, Room 128 Dirksen Senate Office Building
Industries, along with federal and state governments, have invested nearly $5 billion in the development and demonstration of hydrogen and fuel cell technologies. Many studies by DOE, the National Academies and industry have clearly shown the technical barriers that need to be overcome and the pathways to commercial success. Considerable progress has been made in identifying and solving key technical problems. Early market applications like portable and backup power, materials handling equipment and municipal buses are growing, building technical bridges to more widespread market applications - especially in the transportation sector.
The greatest gains in end use efficiency and greenhouse gas reductions will come with mass markets - Zero Emission Vehicles running on domestic hydrogen. Some 350-380 million light duty vehicles could be on U.S. roads by 2050, yet today's fleet of some 230 million gasoline vehicles emit over a third of all our CO2. Replacing oil and taking the auto out of the environmental equation is a complex and lengthy undertaking, and a balanced portfolio is critical if government's leadership role in research, development and demonstration is to achieve real value. Consequently, the FY 10 DOE Budget Request to zero hydrogen programs is of serious concern.

Hydrogen Road Tour 2009
Hydrogen Vehicles Drive from Mexico Border to Canada
Washington DC--May 21, 2009--Today, the National Hydrogen Association announced the beginning of the 1,700 mile 2009 Hydrogen Road Tour. For nine days starting May 26, Americans and Canadians in 28 cities between southern California and Vancouver, British Columbia will have a unique opportunity to see what the transportation future holds for with the launch of a nine-day caravan of clean, efficient hydrogen fuel cell electric vehicles.
The California Air Resources Board, California Fuel Cell Partnership (CaFCP), Powertech Labs (on behalf of British Columbia), National Hydrogen Association and the U.S. Fuel Cell Council are organizing the 2009 Hydrogen Road Tour. Vehicles from seven major automakers will turn heads as they make the trek from border to border. The Tour will stop in 28 communities along the route, with special focus on the communities where hydrogen technologies-passenger vehicles, transit buses and hydrogen stations-will likely enter the market first.
"The Hydrogen Road Tour is another example that hydrogen fuel cell vehicles are not a science experiment. These are real vehicles with real marketability and real benefits," said Jeff Serfass, President of the National Hydrogen Association. "So far, these facts have escaped the notice of the Secretary of Energy's attention, given the request to eliminate the federal hydrogen vehicle program. The Tour will show how capable today's hydrogen fuel cell electric vehicles are by providing performance, environmental responsibility, a reduction of fuel imports and a pleasant driving experience for anyone who gets behind the wheel."
The NHA's recent Energy Evolution reports shows how scenarios that initially use a mix of vehicles with sales later dominated by hydrogen vehicles can address greenhouse gas pollution, oil imports and urban air pollution. Specifically, the Energy Evolution shows that fuel cell electric vehicles powered by hydrogen can simultaneously cut greenhouse gas pollution by 80% below 1990 levels; help the U.S. reach petroleum quasi-independence by mid-century; and eliminate nearly all controllable air pollution by the end of the century."
On the Hydrogen Road Tour, the public will be able to see the latest hydrogen fuel cell electric vehicles from Daimler, General Motors, Honda, Hyundai-Kia, Nissan, Toyota and Volkswagen-including several new models-as well as fuel cell transit buses at several stops. Air Products and Chemicals, Inc. and Powertech Labs are providing hydrogen fuel and mobile refueling stations.
Currently, over 300 zero-emission fuel cell vehicles have been placed on U.S. roads along with 62 operational hydrogen fueling stations in anticipation of plans released by automakers, energy companies and government agencies to collectively roll out 4,300 passenger vehicles to customers in California by 2014. In addition, transit agencies operate fuel cell buses, including BC Transit in Vancouver which will operate a fleet of 20 fuel cell buses for the 2010 Winter Olympic Games. Cities, businesses and military bases in California, Oregon, Washington and many other American states are implementing other projects that use fuel cells, including forklifts and stationary power for buildings and cell phone towers.
