A new assessment of the viability of coal-to-liquids (CTL) technology by researchers from the MIT Joint Program on the Science and Policy of Global Change (JPSPGC) found that without climate policy, CTL has the potential to account for around a third of global liquid fuels by 2050. —Chen et al. Henry, J.M. Reilly and S.
Associate Professor Akshat Tanksale from the Department of Chemical and Biological Engineering at Monash University and co-corresponding author, says OME (oxymethylene ethers) are among a number of fuelalternatives that are attracting increasing attention for their net-zero carbon emitting properties. —Dr G Valavarasu from HPCL.
The resulting biofuel, n -butanol, is a carbon-neutral fuelalternative that can be used in blends with diesel or gasoline. We hope that it can be a steppingstone for future sustainable solar fuel production. The results are reported in an open-access paper in the journal Communications Biology. —Wei Bai.
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.
Critical enablers requiring immediate development are: Flexible economic and engineering models capable of evaluating the wide variety of proposed approaches for alternativefuel facilities and supply chains. Current economic and engineering models were developed with assumptions that do not match those for alternativefuels.
While vehicle efficiency will be the most important and most cost-efficient way to reduce transport-emissions, biofuels will still be needed to provide low-carbon fuelalternatives for planes, marine vessels and other heavy transport modes, and will eventually provide one fifth (2.1
Unlike biomethane produced by anaerobic digestion, Bio-SNG is formed by the conversion of thermally-derived syngas—i.e., Cost of carbon abated for transport applications. Click to enlarge. The report was prepared by Progressive Energy and CNG Services. via the gasification of biomass waste—into methane. Cost of carbon abated.
The interest in microbial synthesis of fuels and chemicals has increased substantially as efforts to transition toward a “bio-based” economy have gained momentum; however, the ability to more broadly use biological systems for chemical production is somewhat limited by the natural repertoire of biosynthetic pathways. —Tseng and Prather.
Conversely, increasing the octane rating of gasoline at constant ethanol content (e.g., The transition would require concerted actions by multiple stakeholders, including fuel producers, fuel distributors and retailers, vehicle manufacturers, and government agencies. E20 95 RON ? —Hirshfeld et al. Hirshfeld, Jeffrey A.
(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.
Lower cost operation due to replacing diesel with lower cost fuelalternatives. The vehicles should be capable of efficiency, reliability, power, and performance comparable to conventional fuel only operation and must be compliant with the latest emission standards for current model year vehicles. Reduced reliance on petroleum.
The research program is focused on the key technology challenges for these concepts and supports cross-cutting activities, including Modeling and Simulation, Structural Materials, Energy Conversion, Nuclear Instrumentation and Control, and Innovative Manufacturing Approaches. Georgia Institute of Technology - $1,046,277.
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.
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.
It takes really long to form fossil fuels They are air pollutants – Combustion of fossil fuels emits greenhouse gases causes air pollution Global warming – as a result of greenhouse gas emission, atmospheric temperature increases ( how? ). Diesel engines can use biodiesel alone or blended with petroleum fuels. #2
