Ultimately, the authors suggest, states can encourage the reduction of fuel GHG emissions by developing policies, such as a low carbonfuel standard (LCFS), that encourage incremental improvements in corn ethanol in the short term and in the medium term by switching to cellulosic-derived fuels. —Boies et al.
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. McCollum et al. Click to enlarge.
A team of biologists and engineers modified Rhodopseudomonas palustris TIE-1 (TIE-1) so that it can produce a biofuel using only three renewable and naturally abundant source ingredients: carbon dioxide, solar panel-generated electricity and light. We hope that it can be a steppingstone for future sustainable solar fuel production.
Cost of carbon abated for transport applications. Although anaerobic digestion of organic material has been widely accepted as an important renewable energy technology, the production of Bio-SNG will required to move to higher levels of fossil fuel replacement, according to the report. Carbon savings. Cost of carbon abated.
Recent work has shown that chemoselective hydrogenation of ring-strained monoterpenes is an effective strategy for the generation of high-performance fuels. Alternatively, the alkenes can be easily converted to cyclopropane rings, which further enhances the density and volumetric heat of combustion (NHOC) of these hydrocarbons.
(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.
The project identifies possible paths to a low-carbon, low-petroleum future in the US transportation sector, and also looks beyond technology to examine the marketplace, consumer behavior, industry capabilities, and infrastructure. The transportation sector accounts for 71% of total US petroleum consumption and 33% of total carbon emissions.
Among these biofuel candidates, C 10 and C 15 terpenes (monoterpenes and sesquiterpenes) have been increasingly used as jet fuelalternatives for commercial aviation and military purpose because of their structures, suitable carbon numbers and reactive olefin functionality, which collectively impart low freezing points and high energy densities.
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. of global electricity demand. —Chen et al. Henry, J.M.
Researchers from Monash University and Hokkaido University have developed a method to produce dimethoxymethane (DMM)—a diesel blend fuel currently of great research interest—via CO 2 hydrogenation in methanol over a novel ruthenium-based catalyst. Their paper is published in the Journal of Energy Chemistry. 2021.07.026.
Each location is regularly supplied with Neste MY Renewable Diesel, a low-carbonfuel produced from 100% renewable and sustainable raw materials that cuts greenhouse gas emissions by up to 80% compared to petroleum diesel. The four new fueling stations join existing Neste-branded fuel stations in San Leandro, San Jose, Keyes and Ripon.
million announced by the FAA to help advance alternative, environmentally-friendly, sustainable sources for commercial jet fuel. LanzaTech’s proprietary gas fermentation technology enables low cost production of sustainable alcohols and chemicals from waste gas resources that are completely outside the food value chain.
Both proposals have the additional advantage of generating funds which may be used to increase investments in low CI fuel technologies. The LCFS program calls for a 10% reduction in the carbon intensity of fuel sold in California over the next decade. The program is agnostic as to which fuels can be used to meet the Standard.
In many natural pathways, a carbon skeleton is initially formed from which a handful of compounds with diverse chemical architecture are generated. The extent to which each of the enzymes will accept the five-carbon unnatural substrates is unknown. —Tseng and Prather. —Tseng and Prather. Hsien-Chung Tseng and Kristala L.
A team from the Loker Hydrocarbon Research Institute and Department of Chemistry, University of Southern California, reports on an improved material for capturing carbon dioxide from the air—silica?organic Narayanan (2011) Carbon Dioxide Capture from the Air Using a Polyamine Based Regenerable Solid Adsorbent. Olah, and S.
We urge European governments and Parliamentarians to support the full carbon accounting of biofuels in order to fix the failing EU biofuels policy once and for all. Commenting on the vote, European environmental NGO Transport & Environment noted that the lack of a mandate creates further uncertainty on the future of biofuels in Europe.
The report also considers the efficiency (and inefficiencies) in the current system, as well as considering the aggressive investments that other trade blocs are making in new infrastructure and lower-carbon transportation—investments that may be outpacing efforts in North America. Shifting to lower-carbonfuels.
Recently, the Energy Resources Center made headlines by saying the EPA’s shift on the Renewable Fuel Standard (RFS) would equal adding 1 million more passenger vehicles on the road. It’s also a political lightning rod given the stagnation of fuel consumption matched with accelerating ethanol blending. Carbon Intensity.
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.
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. Rebecca Boudreaux, President, Oberon Fuels. billion by 2020.
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 vehicle efficiency will be the most important and most cost-efficient way to reduce transport-emissions, biofuels will still be needed to provide low-carbonfuelalternatives for planes, marine vessels and other heavy transport modes, and will eventually provide one fifth (2.1
Global warming due to the emission of gases (Nitrogen Dioxide, Carbon Dioxide, Carbon Monoxide, etc.) from automobiles, environmental pollution, depletion of fossil fuels, etc. make alternativefuels in vehicles a necessity. Kg of Carbon dioxide when it burnt. Kg of Carbon dioxide!!
The California Air Resources Board (CARB) has released the draft 2022 Climate Change Scoping Plan —the third update to the state’s initial 2008 Scoping Plan. It achieves this goal by building on and accelerating regulations, incentives, and carbon pricing that have been in place for a decade and a half.
In our national effort to reduce carbon emissions, we need a practical, all-of-the-above strategy to help us achieve America’s climate ambitions. However, America’s clean energy transition has been characterized by siloed thinking and inflexibility despite significant advances in low-carbonfuelalternatives.
Before greenhouse gasses became a global concern, before we came to terms with the inevitable limits of fossil fuels, natural gas would have been a logical fuelalternative to petroleum. While less polluting than petroleum, burning natural gas emits significant carbon. But we find ourselves in 2008.
