The paper is published in the journal Nature Energy. —Alan Jenn.
Researchers at the Institute of Transportation Studies University of California, Davis suggest that a number of positive trends indicate that we may be seeing the beginning of a real hydrogen transition in transportation, despite earlier starts that fizzled. It appears that these efforts may jumpstart the hydrogen economy at last.
Fulton, UC Davis, examines how major changes in urban transport investments worldwide would affect urban passenger transport emissions as well as mobility by different income groups. Doubling motor vehicle fuel economy requirements could also reduce CO 2 emissions by an additional 700 megatons in 2050. Further, an estimated 1.4
trillion) through to 2050 and can help cut the world’s road transport energy use and CO 2 emissions by nearly half in that same time, by improving vehicle fuel economy, according to an opinion paper recently published by the Commonwealth Advisory Bureau (CAB) and sponsored by the Global Fuel Economy Initiative (GFEI). disaster.
The University of California, Davis, and the China Automotive Technology and Research Center (CATARC) have entered a new agreement to work together to help speed the commercialization of plug-in and fuel cell electric cars in China. Signatories to the MOU include UC Davis Chancellor Linda P.B. Katehi and CATARC Director Hang Zhao.

Meanwhile, significant gains in vehicle fuel economy over the coming decades are possible and very much needed globally in order to address pressing issues of climate change, energy security and sustainable mobility.
A study by researchers at UC Davis suggests that a properly designed vehicle scrappage (i.e., Cash for Clunkers”) program could maximize greenhouse gas emissions savings by using fuel-economy based eligibility requirements rather than age-based requirements. Earlier post.). Allan et al.
The federal government’s Cash for Clunkers aims to stimulate the economy, provide relief for automobile manufacturers and reduce greenhouse gas emissions. Knittel did not analyze the program’s other key objectives: stimulating the economy and providing relief for automobile manufacturers. However, the. pollutants.I
However, research suggests that most consumers have little experience or understanding of electric drive, and have difficulty quantifying their valuation of fuel economy. Willingness-to-pay presumes consumers have preferences about the attributes available in a given choice. Axsen et al.
These experts include Ballard Power Systems, Sacramento Metropolitan Air Quality Management District, UC Davis Institute of Transportation Studies, Railpower Tech LLC, OptiFuel Systems LLC, Valley Vision, Velocity Strategies, and Frontier Energy.
An analysis by a team from the University of California, Davis, MIT and Yale suggests that households that buy a fuel-efficient vehicle tend to compensate for that purchase by buying a bigger, more powerful second vehicle. This unintended effect could erode goals of fuel economy standard policies by up to 60%. Just as Anderson et al.
This facility will better position us to provide critical support to customers in Europe and strategically strengthen our position to be a leader in shaping tomorrow’s hydrogen economy. —Amy Davis, President of New Power at Cummins.
Worldwide, the vehicle fleet is not making enough progress on fuel economy and is failing to reach global targets aimed at reducing CO 2 emissions, cutting oil consumption and improving energy efficiency according to a new report from the Global Fuel Economy Initiative (GFEI) ( earlier post ) released at the Paris COP21 Climate Summit.

Hydrogen fuel cells are a promising solution for the demanding requirements of heavy-duty trucking.
Most of us think "Honda" and bring up economy cars, perhaps lawnmowers, or even portable generators. Yesterday, though, the Japanese carmaker opened its Honda Smart Home US in Davis, California--demonstrating its ideas for how Americans might live a zero-carbon life in the 21st Century. Complete houses aren''t usually on the list.
Cummins’ three-year project aims to automate the manufacturing of SOECs to make production of the electrolyzer systems more efficient, reducing capital costs and facilitating the scale-up of the hydrogen economy. —Amy Davis, Vice President and President of New Power at Cummins.
Vehicle size, a key determinant of fuel economy, has shown a reduction in OECD countries, while the non-OECD trend is toward bigger vehicles. The analysis, an update of an earlier work using data from 2010 and 2011, found that the global average for light-duty vehicle fuel economy was 7.2 Source: GFEI. Click to enlarge. Earlier post.)
With 75% of the fleet expected to serve low-income and disadvantaged communities, Envoy provides equitable transportation for drivers running personal errands, as well those looking to participate in the gig economy and generate income that is 30% higher than the minimum wage.

The 2011 Ford F-150 EcoBoost won in a head-to-head powertrain performance exercise while towing a 9,000-pound (4,082 kg) trailer against the Chevy Silverado and Dodge RAM with much larger displacement V8 engines during a demonstration staged by Ford near Davis Dam in Arizona. The head-to-head contest was the latest phase of the new V6 3.5-liter
EDI was co-founded by Professor Andy Frank from UC Davis—a key figure in the development of the PHEV concept and technology—in 2006. EDI’s solution can improve the fuel economy of a conventional CNG-powered medium-duty truck by more than 40%, the company said.
At the University of Oxford’s Department of Engineering Science, Dr. Martin Davy will lead the project on compression ignition in diesel engines. We are on a very positive trajectory to reduce vehicle emissions and improve fuel economy.
However, increased dilution leads to increased combustion instability resulting in reduced fuel-economy benefits. Davis (UC Davis), R.Sankaran (ORNL). Some strategies to reduce emissions include running the engine highly dilute, with excess air or with recirculated exhaust gases as part of the combustion charge. Description.
Staff also briefed the Board on staff’s assessment of the effects of the economy on emissions from In-Use On-Road and In-Use Off-Road regulations. Tran had falsely claimed a doctorate in statistics from UC Davis. He has a master’s degree in the subject from UC Davis. “Dr. Economy alone does not achieve needed PM reductions.
At the close of the meeting, Governor Brown and Chair Nichols agreed to establish a new working group through the China-US ZEV Policy Lab at UC Davis to expand cooperation with Chinese zero-emission vehicle and battery technology companies. We need a great leap forward. —Governor Brown. [In
Those policy options, when combined, could lead to a zero-carbon transportation system by 2045, while also improving equity, health and the economy. The University of California demand study was conducted by researchers from the UC Institute of Transportation Studies , a network with branches at UC Davis, UC Berkeley, UC Irvine, and UCLA.

The demand for oil in 2015 will drop to its lowest level since 2002 because of an oversupply of crude and stagnant economies in China and Europe, according to OPEC’s latest forecast. by Andy Tully of Oilprice.com. And that’s just one of several sour estimates. OPEC’s monthly report said demand for the cartel’s oil will fall to 28.9
You can demand that the country cuts CO 2 production by 60%, but to do this successfully you need to have a good idea of how to cut pollution at a local level without devastating local economies. Rather than creating low-carbon pathways at a national level, we need a pathway for each city. 6, eaaq0390 doi: 10.1126/sciadv.aaq0390.
A program like this also continues to move us toward a carbon free economy by enabling higher levels of renewable generation to be integrated with the grid. This first-of-a-kind program will help address peak energy demands, minimize impacts to the grid and support the expansion of EV charging in our community.
