Policies to entice consumers away from fossil-fuel powered vehicles and normalize low carbon, alternative-fuelalternatives, such as electric vehicles, are vital if the world is to significantly reduce transport sector carbon pure-emissions, according to a new study. —David McCollum.
For vehicle manufacturers to optimize engine designs to use the combustion advantages of higher-RON, higher-ethanol content fuels, these fuels would have to be readily available nationwide and competitively priced with other liquid fuelalternatives, particularly during a transition to a national high-RON E20 or E30 standard.
While it is unlikely that policies will be crafted to include uncertainty analysis, these results highlight that FCI point estimates alone do not guarantee accurate accounting of possible GHG reductions from different fuels and will thus hamper effective choices of fuelalternatives. —Boies et al. —Boies et al.
Analyzing the potential of various OME n as diesel fuels identifies OME 3–5 as the most promising mixture. The researchers reviewed liquid fuelalternatives that could be used in existing vehicles in the transportation sector. Their composition depends on the production process. —Schemme et al. Molecular structure.
(The comparison to the electric vehicle is based on estimates which factor in the CO 2 emissions resulting from fuel production, with the DME-powered vehicle figure calculated from the use of renewable energy to generate the DME fuel, and the electric vehicle figure calculated from electricity generated from renewable resources.
Examples of topics of interest are new reactor designs and technologies; advanced fuel cycles, including advanced nuclear fuels; alternate aqueous and dry processes, including volatility and ionic liquids; instrumentation and control/human factors; radiochemistry; and fundamental nuclear science. List of selected projects.
Oberon units have the capacity to produce 10,000 gallons of DME per day to service regional fuel markets. Because DME can be produced from natural gas, its use could provider another value-added product from Alberta’s resources. The partners noted that the global DME market is expected to grow to $13.1 billion by 2020.
The ability to economically and easily break cellulose into sugars is desirable because the sugars can be used to create fuelalternatives. Not only are the fibers incredibly strong, but they are incredibly resistant to the action of enzymes (cellulases) that can crack the fibers back into their simple-sugar components.
The analysis emphasizes the importance of regional alternativefuel strategies. Ethanol should be pursued in areas near feedstock production, while different transportation fuelalternatives, such as plug-in hybrids, should be explored in other areas remote from feedstock sources. Wakeley et al. Wakeley, Chris T.
While fossil fuels will be used for as long as they can be easily and economically produced, it should also be clear that their amounts are finite and that they are increasingly depleted. Alain Goeppert, Miklos Czaun, Robert B. Surya Prakash, George A. Olah, and S.
