Trends in well-to-wheel pathway-specific CI. Click to enlarge.
In a new, comprehensive study, a team from Argonne National Laboratory, Stanford University and UC Davis ITS has estimated the well-to-wheels (WTW) GHG emissions of US production of gasoline and diesel sourced from Canadian oilsands. This range can be compared to ∼4.4 g CO 2 e/MJ for US conventional crude oil recovery.
A plot from the TIAX study of the ranges of well-to-wheel emissions for different types of crudes in different refinery areas in the US for gasoline production. The yellow bar is the range calculated for different conventional crudes. GHG emissions for oilsands crudes will further decrease through technological advances.
An analysis of the US refining sector, based on linear programming (LP) modeling, finds that refining plausibly high volumes of Canadian oilsands crudes in US refineries in 2025 would lead to a modest increase in refinery CO 2 emissions (ranging between 5.4% to 9.3%) from a 2010 baseline, depending upon the supply scenario.
Comparison of the percent differential for WTW (well-to-wheel) GHGs from gasoline produced from WCSB oilsands using different production processes relative to gasoline produced from reference crudes. The proposed Project is not likely to impact the amount of crude oil produced from the oilsands.
Backed by a $25-million US Department of Energy (DOE) award, the Honeywell UOP Integrated Biorefinery will utilize rapid thermal processing (RTP) technology ( earlier post ) to convert biomass into a pourable, liquid bio-oil (pyrolysis oil). approx 75 wt%) of liquid bio-oil from residual forestry or agricultural biomass.
The study was commissioned by the European Oilseed Alliance (EOA), the European Biodiesel Board (EBB) and the European Vegetable Oil and Proteinmeal Industry (FEDIOL). In addition, they argue, biofuels should not just be compared to the average performance of gasoline or diesel but with the fossil fuels they most likely replace—i.e.
Gasoline section shows results for fuel derived from both conventional oil and oilsands. However, the range in values for shale and conventional gas overlap, so there is a statistical uncertainty whether shale gas emissions are actually lower than those of conventional natural gas.

Comparison of GHGenius, JACOBS, TIAX, and the new PRELIM gasoline greenhouse gas (GHG) estimates using base case estimates and variations from the scenario analysis. The configurations are differentiated by the presence of gas oil hydrocracking; fluid catalytic cracking (FCC); delayed coking; and residual hydrocracking.
A University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. Water from mining of oilsands and oil shale. —Professor Andy Hong.
Range of average vehicle efficiency. China will see the largest increase—more than 4 million oil-equivalent barrels per day. ExxonMobil projects global demand for gasoline (including ethanol) to be relatively flat from 2010 to 2040, largely because cars and other light-duty vehicles will become much more efficient.
While a number of studies have tired to assess the water consumption required for ethanol production, the results differ by orders of magnitude, with estimates ranging from 1.1 BW consumption intensities of gasoline from conventional crude oil and Canadian oilsandsrange from 0.41 Click to enlarge.
Very broadly, they found that an LCFS would buffer the economy against global oil price spikes, trim demand for petroleum, and lessen upward pressure on gas prices. Set a target of reducing the carbon intensity of gasoline and diesel by 10 to 15 percent by 2030. Create separate fuel pools for gasoline and diesel.

Water Supply, Researcher Says By Jennifer Bogo Popular Mechanics March 7, 2008 "A 30-mile commute in a gasoline-powered car would require the withdrawal of 18.9 All told, electric miles necessitate threefold the water consumption and 17 times the water withdrawal of gasoline miles. And what about the water used to refine gasoline?
The Natural Bridge to an EV Escaping the High Price of Fuel The natural bridge from a gasoline-powered car to an electric vehicle is a plug-in hybrid electric vehicle (PHEV). A 37-mile range EV Electric and Gasoline Power The 2023 Ford Escape PHEV is powered by a 2.5-liter miles per gallon combined gasoline and electricity.
Running on 87 octane, the front wheels (all-wheel drive is not available) are driven through a Continuously Variable Transmission (CVT) that has five driver selectable drive modes of Eco, Normal, Sport, Slippery and Snow/Sand. The Environmental Protection Agency, EPA , rates fuel economy at 40 highway when running in gasoline mode only.
The Corsair was first only available with a gasoline engine, but in 2022 the efficient plug-in-hybrid (PHEV) was introduced. The perfect bridge between a gasoline-propelled vehicle and one that runs purely on batteries is making more sense to people. You can do the math on how much money you would not be spending on gasoline.
If you consider buying one, make sure you plan on spending time off-pavement seeking sand, mud and snow, as its DNA is far different from any other SUV on the market. liter turbocharged gasoline engine. But when including the electric range of 21 miles, the city and highway combined number is 49 mpge. The first is that the 17.3
Compared to a traditional flow battery of comparable size, it can store 15 to 25 as much energy, allowing for a battery system small enough for use in an electric vehicle and energy-dense enough to provide the range and the speedy refill of a gasoline-powered vehicle. Raise that to 40 percent, and the range would climb to 274 km.
To maximize performance and efficiency there are five driver selectable drive modes of Conserve, Normal, Excite, Slippery and Snow/Sand. MPGe is a measurement of how far a car can travel, electrically, on the same amount of electric energy as is contained in 1 gallon of gasoline (33.7 News: 2022 Range Rover Line-up. per gallon.
That’s three times the output of the Buick-based Rover V-8 that first powered these trucks in 1979, and nine times that of the anemic 50-hp gasoline engine the Rover boasted at its birth, in 1948. recently adopted for standard-range Teslas in the United States).

Domestic production of crude oil has increased significantly, from approximately 5.5 That portion of the pipeline has already been built. million bpd in 2010 to 6.5
Folks who quote the math of the old system like a well memorized mantra are limited by the notion that no other system will ever exist, while in fact, super capacitive storage systems currently use higher voltages, in the 3000 volt range and rising, to attain larger power transfers, faster, and on lighter wiring!
This is the first implementation of such a system in a turbocharged direct-injection four-cylinder gasoline engine, noted Lemke. Other features include a new, lighter turbocharger/cylinder head assembly; the use of lightweight polymers for the oil pan, and use of aluminum for various screws and fasteners. now can get up to 36 mpg (6.5
In a pre-response to that speech, having successfully advocated for plug-in hybrids like the forthcoming Chevy Volt, we propose that the President follow that speech up with a “realistic and conservative” roadmap to halve our oil use in 10 years. Oil is holding us all hostage, economically and physically. Finally, it’s time to begin.
The new Ecotec portfolio will include 11 engines, with three- and four-cylinder variants ranging from 1.0L —including turbocharged versions—and power ratings ranging from 75 horsepower (56 kW) to 165 horsepower (123 kW), and torque ranging from 70 lb-ft (95 N·m) to 184 lb-ft (250 N·m).
The determination by the State Department brings to an end the much delayed, deferred and debated permit process that would have allowed TransCanada to built the fourth phase of its Keystone pipeline system to bring more oilsands crude from Canada to refineries in the US.
