A study by researchers at the University of Texas found that in general, use of plug-in hybridelectric 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.
Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory (NREL) modeled the emissions impact had plug-in hybridelectric vehicles (PHEVs) replaced light duty gasoline vehicles in the Denver, Colorado area in summer 2006. million vehicles and would have increased by 3 tpd from power plants.
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.
Five technology paths for very-low-NO x and GHG emissions from heavy-duty natural gas engines. The “Pathways to Near-Zero-Emission Natural Gas Heavy Duty Vehicles” report, authored by GNA on behalf of Southern California Gas Co. Click to enlarge. Click to enlarge. Background. Click to enlarge.
The program funds projects to encourage the development and use of new technologies and alternative and renewable fuels, including electricity, natural gas, biomethane, hydrogen, and gasoline and diesel substitutes, such as cellulosic ethanol (derived from woody materials, including agricultural waste), and biodiesel from waste grease.
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 hybridelectric-powered buses.
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. Approximately 70% of the reductions needed to meet the ozone standard in the South Coast in 2031 would come from existing or proposed regulatory actions.
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 hybridelectric vehicles.
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.
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. A recent Abt Associates, Inc.
Widespread adoption of electric transportation, including electrification in the off-road sector, could lead to substantial reductions in greenhouse gas (GHG) emissions and could modestly improve air quality, according to a new analysis released by the Electric Power Research Institute (EPRI) and the Natural Resources Defense Council (NRDC).
The basic question addressed, which appears on the study homepage (epri-reports.org) is this: How would air quality and greenhouse gas emissions be affected if significant numbers of Americans drove cars that were fueled by the power grid? The use of electricity is an important attribute of PHEVs. I truly hope we have turned a corner.
NO x is a precursor for both ground level ozone and secondary PM 2.5 It is important to state that there are several technology paths to achieve these levels of emissions, and some of them can simultaneously lower greenhouse gas emissions, such that the NO x reductions do not compete with the CO 2 reductions. g/bhp-hr.
With the third generation Nautilus now coming in a hybrid variant, you can add fuel efficiency for long comfortable road trips. Our time in the midsize 2024 Nautilus Black Label AWD Hybrid was a smooth and quiet experience, with a lush ride and all the features expected in an $80,000+ vehicle.
The approach described is designed to meet simultaneously federal air quality standards; achieve greenhouse gas emission reduction targets; reduce petroleum consumption; and decrease health risk from transportation sources through 2030. ARB staff will provide the Board an informational briefing on the proposed strategy on 22 October.
Implementing these approaches, the report finds, would reduce greenhouse gas and other harmful emissions from diesel-powered ships, trucks and other port equipment. Many ports and related freight corridors and facilities are located in nonattainment or maintenance areas for EPA’s ozone and PM 2.5 Click to enlarge.
The transition away from gasoline and diesel vehicles to electric vehicles (EVs) is going full throttle in the United States, and that includes the iconic yellow school bus. Here are several reasons for school districts to switch to electric buses.
Colorado has voted to approve a new standard on the adoption of electric vehicles (EVs), with an additional goal set for 2032 and new guidance for increasing EV sales beginning in 2027. Notably, the release says that the standard does not prohibit the sale or use of non-electric vehicles with internal combustion engines (ICEs).
BNSF has been operating four liquefied natural gas yard locomotives in downtown Los Angeles since the mid-1990s. NO x helps create ground-level ozone, or smog. Diesel exhaust contains a variety of harmful gases and more than 40 other known cancer-causing substances.

Automakers agree on common plug to recharge electric vehicles by Darren Murph , posted Apr 19th 2009 at 4:24PM Just hours after General Motors put forth a proposal for a standardized plug for electric vehicles , in flies this. Were still using the same style electrical plug 70 years later. yay same plug!
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. We quantify the effects of these trade-offs in terms of emissions reduction and fuel burn increase using representative engine cycle models provided by a major aero-gas turbine manufacturer.
million in rebates for plug-in hybrid and zero emissions vehicles as part of an overall $42.3 battery electric or fuel cell) and plug-in hybrid light-duty vehicles and up to $20,000 for the purchase of ARB-certified or approved zero-emission commercial vehicles on a first-come, first-served basis.
The California Air Resources Board released the draft proposed first update to the AB 32 Scoping Plan, which guides development and implementation of California’s greenhouse gas emission reduction programs. The Air Resources Board is required to update the Scoping Plan every five years.

Current Legal Requirement for Use of Anhydrous Ethanol in the United States. 40 CFR § 80.27 addresses controls and prohibitions on gasoline volatility.
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.
Another one of the 13 projects is led by Sepion Technologies, which will partner with LBNL to make new membranes to increase the lifetime of Li-S batteries for hybrid airplanes. High-performance computing offers critical new insight into these phenomena, which in turn will accelerate the product’s entry into the market.
In 2014, Volkswagen of America announced that starting with the launch of the zero-tailpipe emissions battery-electric 2015 e-Golf ( earlier post ), it would invest in projects to offset the carbon emissions created from the e-Golf on a full lifecycle basis: production, distribution and up to approximately 36,000 miles (57,936 km) of driving.
