A study by researchers at the University of Texas found that in general, use of plug-in hybrid electric vehicles (PHEVs) can lead to an increase in ozone during nighttime hours (due to decreased scavenging from both vehicles and EGU stacks) and a decrease in ozone during daytime hours.
The rapidly growing space industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study led by UCL and published in the journal Earth’s Future as an open-access paper. The space industry is one of the world’s fastest growing sectors.
The coordinated package of regulations will reduce emissions of greenhouse gases and ozone- and smog-causing pollutants from new passenger cars, trucks, and SUVs starting in model year 2026.
Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory (NREL) modeled the emissions impact had plug-in hybrid electric vehicles (PHEVs) replaced light duty gasoline vehicles in the Denver, Colorado area in summer 2006. Ozone concentration increases were modeled for small areas near central Denver.
OptiFuel Systems, a system integrator of Cummins and BAE Systems hybrid power products for decarbonizing the rail, marine, and microgrid power market, is in the process of finalizing a $2.6 million US Department of Energy (DOE) grant to demonstrate a pre-production Renewable Natural Gas (RNG) hybrid 4,300 hp line-haul locomotive.
At cruising altitude, airplanes emit a steady stream of NO x into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. Due to its size, any SCR system will likely need to be housed in the aircraft body, potentially making it most suitable for future hybrid- or turbo-electric aircraft designs.
Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles. 10 ) of urban air, a fraction known to be enriched with non-tailpipe constituents.
A new report from the US Environmental Protection Agency (EPA) finds that air pollution at US ports can be reduced significantly at all port types and sizes through a variety of strategies and cleaner technologies. In 2030, adding plug-in hybrid electric vehicles to these fleets could yield even more NO x and PM 2.5 Click to enlarge.
Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. Hybridization. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels.
The California Air Resources Board (CARB) approved a plan to mitigate statewide harm from more than 10,000 tons of smog-causing pollutants released in the state due to Volkswagen’s (VW) use of illegal “defeat devices” in diesel passenger cars. More than 10 million Californians live in areas in extreme non-compliance areas for ozone.
CARB also adopted a new plan to curb destructive “super pollutants” including black carbon, fluorinated gases and methane. The plan, California’s Short-lived Climate Pollutant Reduction Strategy, maps out the route to more rapid greenhouse gas reductions by clamping down on these super pollutants. emissions by more than 20%.
Each of the four recipients will match a percentage of the grant amount with their own funds to purchase compressed natural gas-powered vehicles; retrofit diesel engines with cleaner technology; replace older, more polluting diesel buses with cleaner diesel buses; or purchase hybrid electric-powered buses.
This problem is even more pronounced in hybrid-electric vehicles, which require special measures to address evaporative emissions as the gas engine only operates intermittently, creating the need to store pressurized fuel vapor. A Fuel Tank Isolation Valve is offered for use in hybrid electric vehicles. Fuel tank with Eaton components.
One hybrid electric vehicle (HEV) equipped with a PFI engine was also used. The test fleet showed statistically significant effects for some pollutants, but not for others. The vehicle test matrix had provisions for five vehicles on each emissions standards category (i.e., SULEV30, ULEV50, ULEV70, and ULEV125).
Simply put, the study found what advocates of electric transportation have long held to be true: as regards greenhouse gases and pollution generally speaking, the worst electricity is still better than petroleum. And the grid is getting cleaner and more renewable every year. I truly hope we have turned a corner.
A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.

The on-road transportation (ORT) and power generation (PG) sectors are major contributors to CO 2 emissions and a host of short-lived radiatively-active air pollutants, including tropospheric ozone and fine aerosol particles, that exert complex influences on global climate. Unger et al. Click to enlarge. Unger et al.
15 million for medium- and heavy-duty electric truck and hybrid vehicle demonstration projects. $12 Replacing older, high-polluting buses and vehicles with new CNG buses and vehicles can help reduce greenhouse gas emissions. An estimated 68 stations are needed to support the anticipated rollout of these vehicles in 2015-2017.
life-cycle study of three Li-ion battery chemistries for plug-in hybrid (PHEV) and battery-electric (BEV) vehicles generated a number of findings and identified opportunities for improving the environmental profile of Li-ion batteries for use in plug-in and electric vehicles. Source: “Application of LCA to Nanoscale Technology”.
While it’s obvious that the internal combustion engine vehicles are polluting the air outside the buses, what you may not know is that numerous studies show that the pollution from the burning diesel regularly makes its way into the buses.
This study builds on the 2007 Environmental Assessment of Plug-in Hybrid Electric Vehicles by EPRI and NRDC ( earlier post ), which showed that plug-in hybrid electric vehicles could contribute to reductions in national greenhouse gas emissions, while also leading to improved air quality. levels throughout the United States.
NO x is a precursor for both ground level ozone and secondary PM 2.5 Technologies such as CDA and 48V mild hybridization can enable simultaneous NO x and CO 2 reduction, and once implemented, these technologies will deliver fuel savings to truck owners. g/bhp-hr and a Low Load Cycle (LLC) limit below 0.2 g/bhp-hr.
ARB staff developed this strategy using a multi-pollutant scenario planning tool ( Vision 2.0 ) that quantifies changes in ozone and PM 2.5 precursor emissions; GHG emissions; petroleum usage; and diesel toxics emissions as various technologies become widespread in vehicle and equipment fleets. Click to enlarge. Passenger vehicles.
NO x helps create ground-level ozone, or smog. Both pollutants are particularly harmful to children, the elderly and those who have preexisting health problems. Because of significant mitigation measures put in place over the last two years, risk levels around major rail yards have already been reduced by about 37 percent.
In the release, Colorado clarifies that it includes battery-electric, plug-in hybrid electric and fuel cell electric as what it refers to as zero-emission options. The state has also said that it’s aiming to get one million zero-emission vehicles on its roads by 2030, along with its plan to eliminate greenhouse gas pollution entirely by 2050.
Air pollution remains a major threat to the health of many Americans, but stricter emissions rules could help, according to the American Lung Association. population—live in areas with unhealthy areas of air pollution. And spikes in deadly air pollution are the most severe recorded in the history of the report.
Now it is going to convert all 5,065 taxis to run on natural gas by the end of the year - since last year Dubai has been replacing its existing taxi fleets with eco-friendly cars that run on hybrid engines. The taxis and buses to be introduced by Sharjah will provide further incentives for people to opt for cars with a healthier track record.
Researchers were able to track that data via a network of sensors around the Bay Area that monitor both CO2 and five critical air pollutants: carbon monoxide, nitrous oxides (NO and NO 2 ), ozone, and particulates (PM 2.5).
I mean, when the electricity it uses is produces, pollution still happens, just not "right from your car"? Having centralized energy production in that way allows for centralized pollution control measures, filters, so-called "clean coal" rather than depending on X number of cars, manufacturers, and consumers to deal with pollution control.
EVs don’t emit any harmful pollutants to the environment like soot, hydrocarbons, lead, ozone, carbon monoxide, or volatile organic compounds. These charge points will come in handy for plug-in hybrids and EVs. Why purchase an EV. Besides fuel cost savings, you might want to purchase an EV because of its low carbon footprint.
The update identifies eight key sectors for ongoing action: Energy; Transportation, fuels, land use and infrastructure; Agriculture; Water; Waste management; Natural lands; Short-Lived Climate Pollutants (such as methane and black carbon); and Green Buildings. Transportation.
The facility will support new hydrogen fuel cell electric hybrid trucks being developed for use at the Port of Houston. In addition, the station offers the opportunity to provide fuel for future hydrogen equipment and vehicles used at other facilities, including warehouses and distribution facilities.
The South Coast air district is teaming up with air districts in the Bay Area, Sacramento, San Diego and San Joaquin Valley to make the project a statewide demonstration of 43 zero-emission battery electric and plug-in hybrid drayage trucks built by the four manufacturers serving major California ports.
