At the current pace of research and development, replacing gasoline and diesel with renewablefuelalternatives could take some 131 years, according to a new University of California, Davis, study using a new sustainability forecasting approach based on market expectations. The forecast was published online 8 Nov.
In marine transport there is a particular need to develop low-sulfur fuelalternatives to conventional fossil bunker oils due to upcoming regulations which demand that low-sulfur fuels shall be used in shipping in various regions. ReShip - Renewable wood-based biofuels for Shipping.
Neste, the world’s leading producer of renewable diesel, has opened four new fueling stations in northern and central California, providing greater accessibility to 100% renewable diesel. The fueling stations are open 24/7 and provide a seamless and quick customer experience. billion gallons of fossil diesel.
The advanced biofuels, derived from higher alcohols, alkanes/alkenes, fatty acid esters and isoprenoids, are sustainable energy alternatives, with favorable properties and great market potential. cedrene, were hydrogenated to generate a fuel blend with 12% higher volumetric net heat of combustion than conventional jet fuel.
Volpe Center, to accelerate commercial availability of alcohol-to-jet (ATJ) renewable drop-in aviation fuel. million announced by the FAA to help advance alternative, environmentally-friendly, sustainable sources for commercial jet fuel. at an ICAO sustainable alternativefuels workshop in October.
The authors then incorporated the LCA results into multiple policy scenarios to demonstrate the effect of policy configurations on the use of alternativefuels. renewablefuel standards—and LCFSs. Uncertainty analysis is important to determine the risk of fuels’ environmental impacts. —Boies et al.
Getting to the point where biomass could provide 100% of vehicle liquid fuels requires reducing the need for fuel through efficiency and demand management, including deployment of electricity or hydrogen fuelalternatives. 3%), and these costs can be made up for in fuel cost savings of more efficient advanced vehicles.
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.
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. Few other renewable vectors are as fungible, with so few demand-side constraints.
Further development and testing is needed to adapt DFI to engines for real-world use, but this approach combined with oxygenated fuel could translate into cleaner, more cost-effective MCCI engines that run on diesel with renewable content. Renewable Feedstocks to Produce Commercially Viable Diesel Blends.
Production of CTL has a large carbon footprint, releasing more than twice the lifecycle greenhouse gases of conventional petroleum fuels. However, with the rise in energy prices that began in 2008 and concerns over energy security, there is renewed interest in the conversion technology, the report notes. —Chen et al. Henry, J.M.
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 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 renewableresources.
Due both to the unprecedented nature of the program as well as to the uncertainty regarding the ability of the renewablefuel industry to produce volumes of low CI fuels necessary to meet the required reductions, it is difficult to predict market outcomes and compliance scenarios in the market in coming years. Lade, Gabriel E.
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.
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.
Recently, the Energy Resources Center made headlines by saying the EPA’s shift on the RenewableFuel 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. by Doug Williams.
The publication was prepared jointly by the International Energy Agency’s Renewable Energy Division (RED) and Energy Technology Policy Division (ETP). gigatonnes of CO2) of emission reductions in the transport sector. Technology Roadmap: Biofuels for Transport (IEA 2011).
Disadvantages of fossil fuels Fossil fuels are a non-renewable source of energy which depletes and are not produced as fast as the rate of depletion. These examples of alternativefuels for cars are tested and proven technology in the automotive industry. Why fuel cells are important?
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. The draft 2022 Climate Change Scoping Plan was developed by the California Air Resources Board in collaboration and coordination with multiple state agencies.
Advanced biomass-derived transportation fuels that use a domestic, renewable feedstock provide a secure alternative that reduces the risks associated with petroleum dependence, they said. Enhanced reliability of fuel supplies through diversification to advanced drop-in biofuels is also essential to sustain the U.S.
However, America’s clean energy transition has been characterized by siloed thinking and inflexibility despite significant advances in low-carbon fuelalternatives. But, there is still more that can be done to incorporate low-carbon fuelalternatives into our national climate strategy. It doesn’t have to be this way.
According to current legislation, member states must ensure that renewable energy accounts for at least 10% of energy consumption in transport by 2020. Brazilian sugarcane ethanol is classified as an advanced biofuel by the US Environmental Protection Agency and by California Air Resources Board, even when ILUC effects are taken into account.
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. And today natural gas is a critical fuel for electricity generation. Natural gas, like petroleum, is not forever.
