Biodiesel in United States as Alternative Transportation Fuels

Biodiesel in United States
The United States depends heavily on imported oil to fuel its transportation infrastructure. The use of alternative fuel derived from plant oils was examined by researchers in the mid-1970s to determine if internal combustion engines could be fueled from sources other than petroleum. (more…)

Factors Shaping Automobile Propulsion Technology

Automobile Propulsion
Fuel cell vehicles are being developed because they promise to meet the requirements expected of automobiles in a market increasingly constrained by environmental and resource limitations. Air pollution and oil dependence have been persistent challenges for vehicles powered by petroleum fuels (gasoline and diesel). Global warming presents a new challenge in the need to limit carbon dioxide (CO) emissions from fossil fuel combustion. (more…)

Government Support For Plug-In Hybrid Electric Vehicle

Both state and federal funding is available for research and development of Plug-In Hybrid Electric Vehicle (PHEVs) and other alternative fuel vehicles. On the federal side, incentives are available through the Internal Revenue Service, Department of Energy, Federal Aviation Administration, Environmental Protection Agency, Department of Agriculture, Department of Transportation, and General Services Administration.

Fuel Cell Vehicles Commercialization Issues

Fuel Cell Vehicles

The commercialization prospects for fuel cell vehicles depend not only on their performance and cost, but also on how well they can compete with other technology options that address similar market and policy needs. While market forces have not traditionally motivated design change for reasons of environmental performance, customer values and expectations can evolve and such characteristics could grow in importance. However, inherent market conservatism will favor less disruptive ways to address evolving needs, which might be met by improved gasoline and diesel vehicles, including hybrid-electric versions. Yet looking over the long run, particularly the need to substantially reducing greenhouse gas emissions, hydrogen fuel cells may well provide a solution that is superior to other alternatives.

Fuel Cycle Analysis of Vehicles and Transportation Fuels

fuel cycle

The fuel cycle for a given transportation fuel includes the following processes: energy feedstock (or primary energy) production; biomass feedstock transportation and storage; fuel production; fuel transportation, storage, and distribution; and vehicle operations that involve fuel combustion air or other chemical energy conversions. The processes that precede vehicle operations are often referred to as the well-to-pump (WTP) stage, the vehicle operations are referred to as the pump-to-wheels (PTW) stage, and the entire fuel cycle is referred to as the well-to-wheels (WTW) cycle. Various models have been developed that allow researchers to conduct fuel cycle analyses of vehicle/fuel systems. The GREET (greenhouse gases, regulated emissions, and energy transportation) model, developed by Argonne National Laboratory, is in the public domain and, so far, more than 1000 users worldwide have used the model to predict the energy use and emissions associated with alternative fuels vehicles. The GREET model and its documents are posted on the Internet at http:// greet.anl.gov. (more…)

The European Union Biofuels Distance

I just read a very good news via Reuters. And is that the EU has decided to distance themselves from biofuels usage.

As we here at The Green Blog and often Erenovable, biofuels were a good idea that went astray. They are indeed a renewable energy, “but at the expense of what? Of deforestation, increased food prices, and possible food shortages in the future. Not to mention how undeveloped countries such as Brazil and Argentina are ruining their economies and ecologies because of the monopolization of crops for biofuels. (more…)

Practicality and Reliability of Alternative Fuels and Vehicles

The demand for alternative fuels to substitute current fossil fuels is increasing more that ever. This is because the less availability of fossil fuel and the negative side effects to environment are the main issue that needs to be handled. Renewable energy such as wind, solar, tidal, hydro, geothermal or thermal are gaining more popular. The biomass energy industry in the production of respiration and dead organic matter can be used as industrial production or as fuel. (more…)

Natural Gas Fuel’s Advantages and Limitation

natural gas advantage
Natural gas is found mainly in underground reservoirs and in coal beds. Natural gas is a fossil fuel that consist primarily of methane and some smaller amounts of hydrocarbons subtracts like ethane, propane and butane. There might be some inert gas like nitrogen, helium, and carbon dioxide involved and dissimilated into natural gas. The actual mixture composition is varies depending upon the region where that natural gas is found. (more…)
