Among their findings: The estimated minimum fuel selling prices were $1.22/gasoline The life-cycle greenhouse gas (GHG) emissions of the two pathways were 11.2 Cost breakdown of the minimum fuel selling price for MCCI fuel produced from (a) yellow grease and (b) swine manure HTL, in comparison to the diesel price of $0.79/GLE.
EVs cost an average of $9,406 per year (including the purchase price) to run compared to $7,952 annually for gas vehicles (including the purchase price). per mile to fuel an electric vehicle; by comparison, the national average cost to fuel a gas vehicle is double at $0.06
The SRI CTL plant design offers a lower CO 2 -emitting fuel then conventional diesel; a lifecycle analysis by SRI put conventional diesel at 389 gCO 2 /mile, conventional F-T coal-to-liquids diesel at 830 gCO 2 /mile; and the SRI synthetic fuel at 326 gCO 2 /mile (when using carbon-neutral electricity. Lifecycle GHG comparison.
We project that electric vehicles will save the city $110,000 per year in reduced fuel and maintenance, costs that we would otherwise have to spend on gas-powered vehicles. Between 2009 and 2011, fuel costs for the City of Loveland’s vehicle fleet increased by 29%, according to the case study.
In a paper in the journal Fuel , researchers at Tianjin University report on the use of cooled EGR to improve the overall performance of 2-methylfuran (MF) as an alternativefuel. This work further advances the knowledge of how to improve the overall performance of MF as an alternativefuel for internal combustion engines.
Nanocubes made of metal organic frameworks (MOFs) could serve as a medium for gas storage. MOFs produced by the new method are currently being trialed for natural gas storage in heavy duty vehicles. The larger gas quantity in the tank increases the vehicle’s range. Tags: Hydrogen Storage Nanotech Natural Gas. Photo: BASF.
Medium- and heavy-duty vehicles are a significant component of California’s transportation sector, accounting for a combined 16% of the state’s petroleum consumption and greenhouse gas emissions within the transportation sector; however, these vehicles represent less than 4% of the in-state vehicle population. Natural Gas ($8 Million).
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. —“Factor Analysis of Greenhouse Gas Emissions from Automobiles”.
Comparison of flight scenarios demonstrated that the DELILAH optimal turbocharged diesel engine for light helicopters could potentially reduce fuel consumption by 50%. The engine is compatible with the use of alternativefuels such as 100% biofuel (B100), reducing dependence on fossil fuels and thus reducing greenhouse gas emissions.
The goal of their study was to understand how alternativefuels affect the primary PM emissions, the semi-volatile nature of the these emissions, and the potential for the emissions to form secondary PM. 3 ) may also undergo gas?particle A significant fraction of the organic emissions are low-volatility vapors. 1 and 10 2 ?g
The project will help establish the methodology for making comparisons under such varied conditions. The research is part of a larger effort by the California Air Resources Board to expand the use of hybrid technology to help meet the goals of AB 32, a 2006 state law that aims to reduce greenhouse gas emissions to 1990 levels by 2020.
Comparison of the percent differential for WTW (well-to-wheel) GHGs from gasoline produced from WCSB oil sands using different production processes relative to gasoline produced from reference crudes. This range is equivalent to annual greenhouse gas emissions from the combustion of fuels in 588,000 to 4,061,000 passenger vehicles.
The Current Policies Scenario assumes no new policies are added to those in place as of mid-2011, and is used as a basis for comparison with the New POlicies Scenario. Natural gas also plays a growing role in the transport sector, its share rising from 3% to 4%. the extent of the displacement of oil by alternativefuels.
The Toyota Highlander Fuel Cell Hybrid Vehicle – Advanced (FCHV-adv) ( earlier post ) achieved an estimated range of 431 miles on a single full tank of compressed hydrogen gas, and an average fuel economy of 68.3 Currently, hydrogen gas pricing is not fixed, but DOE targets future pricing at $2 to $3 per kilogram.
SEALNG, the multi-sector industry coalition accelerating the widespread adoption of liquefied natural gas (LNG) as a marine fuel, welcomed Canadian LNG provider FortisBC to the growing coalition. FortisBC brings to the coalition nearly 50 years’ experience in LNG production in Western Canada.
Although Chevy emphasizes the benefits of the 2500HD with the bi-fuel option as a full dual fuel vehicle with a combined range of up to some 650 miles, in more than 500 miles of driving over the course of a week, we used mainly only natural gas. The only reason we used gasoline was for comparison; it wasn’t necessary.
They also found that increasing renewable diesel (Neste Oil’s NExBTL) and gas-to-liquids (GTL) diesel blends showed NO x reductions with rising blend level. In California, biodiesel use accounted for 86% of the alternativefuels consumed by the state fleet in 2010. Earlier post.). NO x increases ranged from 1.5% for B20, 6.4%

How does this relate to the life cycle greenhouse gas (GHG) emissions intensity? Click to enlarge.
In accordance with Directive on alternativefuel infrastructure, Member States are required to implement common standards, including a common plug for electric vehicles, and roll out infrastructure for alternativefuels. This would make charging of electric vehicles easier. Zero-emission vehicles.
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). Click to enlarge.
Renewable feedstock and high octane number rating make ethanol a very promising alternativefuel in CI engine. Due to its superior resistance to auto-ignition (RON = ~111) and volatility compared with gasoline fuel, ethanol is more specifically suited to PPC operation at high load conditions.
None of us were certain whether “charging station” referred to the site or location as in the analogous gas station? For one, clarity and consistency is critical for sharing statistics and making comparisons. million (12 times 145,000) estimated gas pumps. Charging Station Versus Gas Station: Comparing Apples to Oranges.
Consumers have more choices than ever when shopping for vehicles with higher fuel economy and lower tailpipe CO 2 emissions. These choices reflect both a more diverse range of technology packages on conventional gasoline vehicles as well as more advanced technology and alternativefueled vehicles.

It also scales back in areas such as oil and gas company research and moves away from funding vehicular hydrogen fuel cells to technologies “ with more immediate promise, ” according to Energy Secretary Steven Chu. Alternativefueled vehicles pilot grant program: $300 million. Fuel cell technologies: $43.4
If you’re working on increasing fuel efficiency or you already have an alternativefuel vehicle, you can lessen your carbon footprint by taking advantage of green car care, repair and insurance. Hybrid cars use batteries for some driving needs and gas for others. Fuel-Efficient Vehicles. Hybrid Cars.
Doing a price comparison, including the cost of fuel and maintenance, the Lightning Pro matches very well against the competition, especially as a work truck. Our focus is on vehicles that offer the best fuel economy in their class, which leads us to emphasize electric cars, plug-in hybrids, hybrids and other efficient powertrains.
They still have a long way to go before catching up on fossil fuel-powered cars in convenience of fueling. In comparison, only 7,500 hydrogen powered cars were sold by that time. Honda’s Clarify is another fuel cell option. There are some advantages that a BEV has over a hydrogen fuel cell.
