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.
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.
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 global market for rocket launches may require more stringent regulation in order to prevent significant damage to Earth’s stratospheric ozone layer in the decades to come, according to a new study by researchers in California and Colorado. Darin Toohey.
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.
Marine engines are responsible for the emission of many tons of nitrogen oxide (NO x ), an ozone-forming compound, as well as particulate emissions (soot) into the New York airshed. The program will implement emissions control technologies on private ferries operating in New York Harbor.
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.
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 hybrid electric vehicles.
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”.
The committee that wrote the report focused on monetizing the damage of major air pollutants—sulfur dioxide, nitrogen oxides, ozone, and particulate matter—on human health, grain crops and timber yields, buildings, and recreation. Most vehicle and fuel combinations had similar levels of greenhouse gas emissions in 2005.
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? I truly hope we have turned a corner.
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).
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.
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 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. Under current control programs (left) and under the Cleaner Technologies and Fuels scenario (right).
In addition, other studies have shown that increases in PM 2.5 , NO 2 , and ozone were associated with lower test scores that were “equivalent to the effects of short-term reductions of thousands of dollars in district median household income.”
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.
Hybrid vehicle systems have demonstrated significant fuel consumption and emissions reductions in a number of MHDV applications, but their cost prohibits commercial deployment, especially at foreseeable fuel prices. The 21CTP hybrid team is considering a proposal to restructure its mission and focus, which the committee supports.
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.
Now, the Sharjah Public Transport Corporation has taken the decision to introduce gas powered taxi and bus fleets. 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.

This SAE spec would make it so you could go to a gas station and they would have the proper voltage and plug for your car. but its never even been close to the amount of garbage that gas power vehicles produce. This would be like all laptop makers agreeing on the same plug to fit in all laptops.
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.
80.27, “high ozone season” means the period from June 1 to September 15 of any calendar year and “regulatory control period” means the period from May 1 to September 15 of any calendar year. 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 addition to the direct benefits of storing carbon, wood products have also been shown to have fewer associated greenhouse gas emissions compared with concrete or steel. ozone depletion potential (ODP). photochemical ozone creation potential.
