Stability lowers risk, and gives investors, developers, and financiers the certainty that their business models are sound for the life of the project. Also, you can type in a page number and press Enter to go directly to that page in the book. What does oil dependence cost? Important advances are being made, for example, with the harvest, storage, and transport of cellulosic plants in support of pilot plants. Thus, in almost all cases, hydrogen is a key input to the feedstock conversion process.

Renewable Fuel Standard, which sets annual minimum requirements for the distribution of biofuels as a ground transportation fuel. To use the test banks below, you must download the TestGen software from the TestGen website. It is not feasible for the aviation industry to switch from conventional jet fuel to a different fuel type, nor are.

Several government agencies in the United States and elsewhere have been aiding the development of this new industrial sector. We don't recognize your username or password. Engine manufacturers define what fuel types satisfy these criteria using fuel specifications. With this in mind, we learn that the U. InfrastructureNumber of fueling stations in the U.

Automakers are no longer manufacturing methanol-powered vehicles. Energy-dense, inexpensive battery pack Lithium Ion? In contrast, a drop-in fuel that meets appropriate fuel specifications obviates the need for recertification or a large investment in aircraft or engine modifications. Massive consumption of biofuels in the U.

This reduction can also be achieved without impacting the time frame or suitability of other potential carbon-lowering approaches. Limited production and distribution infrastructure.

In most cases, the other names imply specific variants of the fuel, as often detailed in the specifications themselves. Thermochemical conversion of alcohols isobutanol only initially to paraffinic kerosene. Battery technology Lithium-Ion? Also, within an agricultural feedstock family, individual feedstocks are typically only available during certain times of the year.

Hydrogen can be mixed with natural gas to create an alternative fuel for vehicles that use certain types of internal combustion engines. This same issue applies to many nonagricultural feedstocks, too, where intermittency issues may be driven by factors other than harvest availability. Relevant federal agencies include the U. In addition, liquefied natural gas and liquid hydrogen both introduce unique aircraft integration and substantial new safety challenges.

There is no well-defined, internationally adopted framework for sustainability analysis of alternative jet fuels. Regardless, minnesota multiphasic personality inventory mmpi pdf the fuels on this list have the potential to serve as full or partial alternatives to gasoline and diesel. Rationale for Sustainable Alternative Jet Fuels.

If You re a Student

To be considered sustainable, the input feedstocks for the syngas production would themselves need to be viewed as sustainable, and thus some sources of syngas e. Electricity can be used as a transportation alternative fuel for battery-powered electric and fuel-cell vehicles. Where does electricity come from? Examples include waste fats, oils, and grease and nonfood crops, especially those grown on land that is not suitable for growing food crops, are potentially more competitive.

Manufacturers are not making flexible fuel vehicles. As a result, members of the investment and finance community are generally uncomfortable with the risk associated with development of commercial facilities. Sustainability Assessment Models and Requirements There is no well-defined, internationally adopted framework for sustainability analysis of alternative jet fuels.

Operators of aircraft powered by gas turbines will continue to demand the use of hydrocarbon jet fuel for the foreseeable future. Fischer-Tropsch conversion of syngas to synthetic paraffinic kerosene and aromatics.

In many regions associated with abundant supplies of feedstock, hydrogen is not readily accessible, particularly at reasonable cost. Propane produces fewer emissions than gasoline, and there is also a highly developed infrastructure for propane transport, storage and distribution. Uncertainties about the long-term impact of the U. Much has been accomplished, but much remains to be done. Who will pay for the storage?

Large commercial entities e. How likely are these concerns to occur? Fischer-Tropsch conversion of syngas to synthetic paraffinic kerosene.

The portion of biomass-based carbon molecules that constitute the jet fuel cut can be considered as an alternative fuel. We will increase our research in better batteries for hybrid and electric cars, and in pollution-free cars that run on hydrogen. Natural gas is an alternative fuel that burns clean and is already widely available to people in many countries through utilities that provide natural gas to homes and businesses.


As in any industry, investment and engagement are enhanced by long-term, well-defined policies that provide stability. Looking for other ways to read this? Vehicle engines can be converted to burn biodiesel in its pure form, and biodiesel can also be blended with petroleum diesel and used in unmodified engines.
