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.
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.
Hydrogen produced with renewable electricity could compete on costs with fossil fuelalternatives by 2030, according to a new report from the International Renewable Energy Agency (IRENA).
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. —Arpita Bose, associate professor of biology in Arts & Sciences, and leader of the study.
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.
An independent study of ABB Dynafin from OSK-ShipTech A/S of a passenger vessel design equipped with different propulsion solutions has verified savings in propulsion energy consumption of up to 22% compared to conventional shaftline configuration.
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 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.
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.
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.
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.
embarked on a comprehensive and detailed feasibility study on sustainable Biomass-to-Liquid (BTL) jet fuel and possible by-products such as renewable diesel. This study looked at all available bio feedstocks that would not affect the food or fresh water supply chain. Tom Enders, Airbus President and Chief Executive Officer.
(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.
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.
An evaluation of the implementation possibilities of power-to-fuel (PTF) technologies by a team from Forschungszentrum Jülich GmbH in Germany recommends the PTF products DME, OME 3-5 and n-alkanes as suitable diesel alternatives for the transportation sector. A paper on the Jülich study is published in the journal Fuel.
A study published by the National Grid in the UK is suggesting that Bio-SNG (Synthetic Natural Gas) could achieve carbon dioxide (CO2) savings of up to 90 per cent compared with fossil fuelalternatives.
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.
MEPs also voted to include emissions from indirect land-use change (ILUC) in the fuel quality law. Greenhouse gas emissions that result from the increasing use of agricultural land for biofuel production are addressed by studies of ILUC.
A more recent study found that, since the program coaxed farmers into using more land for corn cultivation, RFS biofuel wasn’t actually any less carbon-intensive than gasoline. Amidst a backdrop of rising fuel prices, the Biden administration might bring the RFS its greatest shakeup yet. “How In 2016, a U.S. Now, it is 2022.
