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.
Denver represents an interesting case study for exploring potential PHEV impacts because it violates the federal air quality standard for ozone and because several large EGUs [electricity generating units] are located in or near the urbanized area. Ozone concentration increases were modeled for small areas near central Denver.
The hydrogen produced during electrolysis can be injected into the gas grid, used as fuel, converted into methane or methanol, and made available as industrial feedstock. Micropollutants such as pharmaceuticals, pesticides and cosmetics can be removed from wastewater when ozone is introduced. The hydrogen factory of the future.
is shown with both UK and French grid mixes. Photochemical Ozone Creation Potential (kg Ethene equivalent). Quantifies the production of pollutant ozone (? to ozone layer), the results of the reaction of sunlight on NO x and volatile organic compounds. The EV footprint (Fluence Z.E.)

Power reduction requirements have been phased in over time and fleets can accomplish this by turning off their diesel engines and connecting to grid-based shore power, or by using alternative technologies to achieve equivalent emission reductions while in port.
Use of electric vehicles would achieve greater reductions in GHG emissions, corresponding to the rate that the electric grid becomes cleaner, through greater reliance on renewables and low- and non-emitting generation. With a 62% share of light- and medium-duty vehicles in 2050 electric vehicles would consume 13% of grid-supplied electricity.
These connections arise because in many cases the agents of concern are the same, and in many cases the sources of the agents are the same or intimately connected.For example, surface ozone is both an air pollutant and a greenhouse gas. The complex roles that ozone and aerosols play in the atmosphere provide examples of such trade-offs.
Lux Research positioned key companies on the Lux Innovation Grid based on their Technical Value and Business Execution—companies that are strong on both axes reach the “Dominant” quadrant—and also assessed each company’s maturity, and provided an overall Lux Take. EcoSphere, AquaMost lead in oxidation technologies.
The spatially (12 km grids) and temporally explicit LCI not only provides the level of detail necessary to perform detailed LCIA (life cycle impact assessment) of air pollutant emissions, it also gives information on spatial and temporal trends that can be useful in policy making and regulation, the authors suggest.
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.
Previously, modelers have attempted to account for urban aerosol emissions by using a correction factor, which diluted total aerosol emissions across global model grid cells. This dilution method, however, does not capture the heterogeneity of urban and non-urban areas within each grid cell.
The Afternoon Constellation, so named because it crosses the equator at approximately 1:30 PM local time every day, consists of five existing satellites in tight formation, collecting simultaneous data on aerosols, clouds, cloud ice, carbon sinks, carbon sources, ozone, particulates, and atmospheric water vapor.
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? And the grid is getting cleaner and more renewable every year.
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.
ARB staff developed this strategy using a multi-pollutant scenario planning tool ( Vision 2.0 ) that quantifies changes in ozone and PM 2.5 The electrical grid and hydrogen supply supporting these electric vehicles will need to represent 50% renewable energy generation. Vision 2.0
Smart Grid and Electricity Transmission. The draft contains provisions to facilitate the deployment of a smart grid, including measures to reduce utility peak loads through smart grid and demand response applications and to help promote smart grid capabilities in new home appliances. Partnering with the States.
Grid cells where isoprene mixing ratio is lower than 50 pptv are not shown. Isoprene, a five-carbon diene formed naturally in plants and animals and a precursor of ozone, contributes more than 40% of these emissions. Modeled yield of epoxides from the reaction of isoprene and OH. Paulot et al. Click to enlarge.
Practical solutions must be developed and implemented to overcome barriers to waste gas utilization for pipeline injection and grid interconnection. Organic wastes converted to biogas could supply enough renewable natural gas for about 2 million residential units.
In 2004, the Centralina region (the Greater Charlotte metro area, which straddles the North CarolinaSouth Carolina border) was designated as a non-attainment area for ozone under the Clean Air Act. The area stood to lose billions of dollars of federal funding for a wide variety of projects if the areas air quality didnt improve.
One upcoming technology, Vehicle-to-Grid (V2G or VTG), may allow electric bus fleets to send electricity back to the utility grid during peak energy events.
And in Colorado, lawn & garden equipment contributes about a third as much ozone as the Colorado’s large oil & gas industry, or also about a third as much as all on-road vehicles combined (including heavy duty trucks).

Once weve consolidated everything to depend on the grid, we can clean up everything by cleaning up the grid. Once electric cars are more common, demand for electricity will rise, and electricity producers will have to look at big generators such as dams, nuclear stations or decentralised wind turbines that feed in to the grid.
and of 10 ppb in ozone were associated with increases in all-cause mortality of 7.3% (95% confidence interval [CI], 7.1 of less than 12 μg per cubic meter and ozone of less than 50 ppb, the same increases in PM 2.5 and ozone were associated with increases in the risk of death of 13.6% (95% CI, 13.1 and 1.1% (95% CI, 1.0
Additionally, the study found that the population-weighted mean concentrations of ozone increased globally by 8.9% The estimates are generated from the grid cell average of satellite-based estimates and TM5-FASST simulations and calibrated with a prediction model incorporating surface measurements. and ozone (O 3 ).
The Alzeta Corporation of California will partner with LBNL to destroy effluents from semiconductor processing that could potentially harm the ozone layer in a project titled “Improving Gas Reactor Design With Complex Non-Standard Reaction Mechanisms in a Reactive Flow Model.”.
