note that the focus of their study was motivated in part by the unprecedented rise in popularity of electric two-wheelers in China. While conventional vehicle (CV) ownership and electricity consumption in China are both increasing rapidly—annual growth rates during the past decade were ?25% 13 months). 90% is from coal.
Self Financial, a fintech company, has compared the running costs of electric and non-electric vehicles in each state. Across the US the average annual cost of running an electric vehicle is $2,721.96, while gasoline vehicles cost an average of $3,355.90 per year to run—a difference of $633.94
The prototype is the combination of a flexible-fuel vehicle (FFV) that can be powered by both gasoline and alternativefuels such as ethanol, and Toyota’s hybrid system. Toyota’s initial studies suggest that a Hybrid FFV has an advantage in environmental performance compared to a standard FFV on a well-to-wheels basis.
They found that many alternativefuels consume larger quantities of water on a per km basis than traditional petroleum and natural gas pathways. Well-to-wheels pathways for transportation fuels and passenger vehicles analyzed by Lampert et al. Click to enlarge.
The Sandia researchers showed that the key to meeting the RFS2 targets is the fuel price differential between E85 fuel and conventional gasoline (low ethanol blends), so that E85 owners refuel with E85 whenever possible. The Sandia study examines the set of circumstances under which the RFS2 mandate might be satisfied.

A report prepared by ISIS (Institute of Studies for the Integration of Systems - Italy) together with Tecnalia (Spain) for the European Parliamentary Research Service (EPRS) discusses the technological, environmental and economic barriers for producing methanol from carbon dioxide, as well as the possible uses of methanol in car transport in Europe.
The National Low Carbon Fuel Standard (LCFS) Project has released two major reports that synthesize its findings from the past several years of work: a Technical Analysis Report (TAR) and Policy Design Recommendations. Set a target of reducing the carbon intensity of gasoline and diesel by 10 to 15 percent by 2030.
As a result, BCG concludes, the electric car faces stiff competition from ICEs (internal combustion engines) and, based solely on total cost of ownership (TCO) economics, will not be the preferred option for most consumers. BCG expects pack costs for OEMs will fall to ~$360-440 per kWh by 2020. Source: BCG. Click to enlarge. Source: BCG.
volume and GHG-based fuel standards) to achieve reductions in greenhouse gas emissions from on-road transportation need to evolve towards energy-intensity-based fuel standards (e.g., MJ/km) and complementary regulation of fuel carbon intensity (e.g., From a climate perspective, only the lifecycle emissions of these fuels matter.
Obligated parties are upstream producers and importers of gasoline and diesel fuel sold in the state. The program is agnostic as to which fuels can be used to meet the Standard. As a result, the authors note, industry faces only technological and economic constraints in choosing the optimal fuel mix to comply with the program.
Comparison of brake thermal efficiency and specific fuel consumption at rated power (ICOMIA Mode 5), hydrogen vs. gasoline engines. This is due to raw, externally premixed fresh charge comprising air, fuel and lube oil being short-circuited into the exhaust during the scavenging process. fuel consumption penalty.
John DeCicco at the University of Michigan argues that to reduce transportation sector greenhouse gas emissions, the proper policy focus should be upstream in sectors that provide the fuel, rather than downstream on the choice of fuels in the automobile. The paper is available from the Social Science Research Network (SSRN).
This framework includes electricity and natural gas used in the production of hydrogen. The study published in ES&T was funded by Chevron Energy Technology Company. Tighter sulfur specifications on gasoline and marine diesel fuel account for about 10%?20% California’s Global Warming Solutions Act).
Achieving the reduction will require combined reductions across three factors: modes, demand and fuels. According to the TEF studies, achieving deep reductions are dependent on combined reductions across three factors: vehicle fuel consumption (modes); vehicle use (service demand); and fuel carbon intensity (fuels).
A study by researchers at Carnegie Mellon University has concluded that regulatory incentives for OEMs for alternativefuel vehicles (AFVs) intended to encourage a technology transition in the transportation fleet result in increased fleet-wide gasoline consumption and emissions. Incentives for selling AFVs.
In the study, published in the journal Nature Energy , Noel Melton, Jonn Axsen and Daniel Sperling conduct a media analysis to show how society’s attention has skipped among alternativefuel vehicle (AFV) technology between 1980 and 2013, including methanol, natural gas, plug-in electric, hybrid electric, hydrogen and biofuels.
Covering 23 European markets, the study found that average CO 2 emissions increased by 0.3 g/km in 2017—far higher than the average CO 2 emissions of diesel and gasoline vehicles across all segments. g/km in 2017—far higher than the average CO 2 emissions of diesel and gasoline vehicles across all segments.
Relative changes in vehicle energy efficiency (VEE) (km/MJ) on ethanol/gasoline blends over those on gasoline for different blending levels.

To demonstrate the technique, Kristin Rogers and Thomas Seager applied it to a set of conventional and alternative transportation fuels (carefully noting that their purpose was purpose to illustrate the method, not to provide definitive conclusions about alternativefuels). total US emissions). Rogers and Seager (2009).
The investment plan for 2011-2012 is spread across 11 technologies and areas: Plug-In Electric Vehicles ($8 Million). Sales of in-state plug-in electric vehicles are expected to rapidly increase over the next 2-3 years, as major automakers begin offering fully electric and plug-in hybrid electric vehicles. Ethanol ($12.5
But fuel tax revenues have not kept pace because the federal government and most states have not increased gasoline tax rates since early 1990s, while inflation has eroded their real buying power. In the meantime, cars and trucks have become more fuel-efficient. User Charges Based on Fuel Consumption (Gasoline and Carbon Taxes).
However, widespread commercial use of electric drive on long-haul and heavy-duty routes is not yet feasible. This is where sustainable fuels play a crucial role as they could be pivotal in reducing the climate impact of transport emissions. Liquefied natural gas (LNG) and compressed natural gas (CNG) are considered alternativefuels.
The NRC study is intended to feed into the mid-term review and provide an independent review of technologies and the CAFE program more generally. Michael Sivak of the University of Michigan Transportation Research Institute (UMTRI) examined several topics related to fuel economy and advanced vehicle technologies. gallon and $5/gallon.
Alternative technologies, such as hybrid and electric vehicles that use oil more efficiently or not at all, continue to advance but they take time to penetrate markets. Subsidies that encourage wasteful consumption of fossil fuels jumped to over $400 billion. The passenger vehicle fleet doubles to almost 1.7 billion in 2035.
On average, a 25% reduction in carbon dioxide equivalent (CO2-eq) emissions can be expected on a well-to-wheel (WTW) basis when replacing gasoline by light-duty vehicles (LDVs) running on compressed natural gas (CNG). The paper uses Brazil, India, Iran, Pakistan, the US and Europe as case studies.
Several factors are slowing the development of the market, especially of the more radical alternatives such as battery electric vehicles (BEVs). Green cars” can be defined as vehicles that use alternativefuels (other than petrol or diesel) and/or alternative types of propulsion (other than the conventional ICE).
Light-duty vehicles (LDVs) in the US may be able to reduce petroleum use by 50% by 2030, and by 80% by 2050; and reduce greenhouse gas (GHG) emissions by 80% by 2050, according to the newly published results of a two-year study by a committee convened by the National Research Council.
