The goal of the physical testing program should be to resolve safety issues in advance of commercial use. The use of a combination of natural gas without sequestration and renewable energy can also significantly reduce CO2 emissions.
A particularly salient and underexplored issue is that of leakage in enclosed structures, such as garages in homes and commercial establishments. Page 8 Share Cite Suggested Citation: In its fuel economy estimates presented in Table ES-1the committee assumed that the Tier I emissions requirements imposed by the Clean Air Act amendments of will be met.
Research and Development Priorities There are major hurdles on the path to achieving the vision of the hydrogen economy; the path will not be simple or straightforward. Recent examples include increasing the national maximum speed limit on rural interstate highways from 55 to 65 miles per hour and permitting right-turn-on-red.
Most such changes will increase vehicle weight and thereby decrease fuel economy. Managements Responsibility for The DOE does not yet have a strong program on hydrogen infrastructures. Moreover, productive capacity worldwide and particularly in the United States exceeds prospective demand for new vehicles, which is projected to grow only modestly over the period considered in this study.
The imposition of higher fuel economy standards that are extremely costly or that greatly distort normal product cycles would place an untenable financial burden on the industry.
However, the committee emphasizes the following: The role of the DOE hydrogen program 3 in the restructuring of the overall national energy system will evolve with time. However, even estimates of the fuel economy contribution of technologies already in mass production vary substantially from source to source.
Moreover, light trucks are particularly aggressive to passenger cars in car-light truck collisions. Thus, concern for safety should not be allowed to paralyze the debate on the desirability of enhancing the fuel economy of the light-duty fleet.
The demand for hydrogen in about would be about equal to the current production of 9 million short tons tons per year, which would be only a small fraction of the million tons required for full replacement of gasoline light-duty vehicles with hydrogen vehicles, posited to take place in However, if natural gas is used to produce hydrogen, and if, on the margin, natural gas is imported, there would be little if any reduction in total energy imports, because natural gas for hydrogen would displace petroleum for gasoline.
There could be a penalty for improved fuel economy in this regard, but it should be small. Continue the FutureGen Project as a high-priority task; and Carbon dioxide-free energy technologies.
It appears possible that a lean NOx catalytic system achieving roughly a 50 percent reduction in NOx emissions from the engine and with the required durability will be developed. But making hydrogen from renewable energy through the intermediate step of making electricity, a premium energy source, requires further breakthroughs in order to be competitive.
Within 10 to 15 years, all current models and most engines and drivetrains will undergo at least one major change, and the equipment used in their manufacture will be written off. Basically, these technology pathways for hydrogen production make electricity, which is converted to hydrogen, which is later converted by a fuel cell back to electricity.
Habagatang an analysis of all new people by ann lamott Leyte, Filipino: Page 7 Share Cite Suggested Citation: For example, while the committee makes recommendations on the use of renewable energy for hydrogen production, it did not review the entire DOE renewables program in depth.
These impacts will occur whether or not the government decides to increase future fuel economy standards. Nonetheless, it seems reasonably certain that one or more emerging technologies including some not foreseen in this study will begin to make significant contributions to fuel economy by MY With a new national commitment, our scientists and engineers will overcome obstacles to taking these cars from 1 Criteria pollutants are air pollutants e.
Because the standards are currently set by different agencies under differing statutory commands, little coordination of policy is achieved and inconsistent pressures—such Page 9 Share Cite Suggested Citation: Accordingly, the challenges of developing PEM fuel cells for automotive applications are large, and the solutions to overcoming these challenges are uncertain.
Furthermore, hybrid electric vehicle technology is commercially available today, and benefits from this technology can therefore be realized immediately.
Some of the drivers for such change are already recognized, including at present the geology and geopolitics of fossil fuels and, perhaps eventually, the rising CO2 concentration in the atmosphere. An on-board vehicular hydrogen storage system that has an energy density approaching that of gasoline systems has not been developed.
The National Academies Press. Unresolved issues of policy development, infrastructure development, and safety will slow the penetration of hydrogen into the market even if the technical hurdles of production cost and energy efficiency are overcome.
Technologies that could significantly impact U. The Department of Energy should continue to develop its hydrogen initiative as a potential long-term contributor to improving U.
The committee recommends that the following areas receive increased emphasis: And there is a potential for eliminating almost all CO2 and criteria pollutants from vehicular emissions. How Far Can We Go?. The report focuses exclusively on hydrogen, although it notes that alternative or complementary strategies might also serve these same goals well.
Moreover, more-energy-efficient technologies for the household, office, factory, and vehicle will continue to be developed and introduced into the energy system.for the Gasoline Distribution Industry (Area Sources) Final Report Prepared for Tom Walton small entity impacts analysis for the gasoline distribution industry.
