This project is expected to increase GM’s use of renewable energy to more than 50% of its sourced electricity by 2023, moving GM closer to its goal of sourcing 100% of electricity from renewables in the US by 2030 at GM-owned sites.
KG in the HyPerFerMent I project to produce renewable hydrogen from biomass. Since systemically integrated hydrogen production is important to the researchers, they will not only be using the hydrogen produced during electrolysis but also the oxygen—for welding processes or for ozonation in sewage treatment plants, for example.
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.
Of our "alternative fuel" options, only electricity can truly be made renewably (wind, solar, geothermal, small hydro), with no carbon or other noxious emissions. Tags: renewable electricity ethanol. And only electric drive cars can operate truly zero-emission.
VOCs and nitrogen oxides react with sunlight to form ground-level ozone, the main component of smog. Over the past decade, because of the renewable fuel mandate, we have added 10 percent of ethanol to all the gasoline that is sold in the U.S. and so the question is: what does that do to the environment.
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. water, and non-renewable energies (crude oil, coal.)

For example, states in the western US (WUS) generally produce a larger fraction of their electricity from renewable and/or “emission-free” sources (i.e., Among the findings: Summer surface ozone (O 3 ) decreases in most locations due to widespread reductions of traffic NO x emissions. coal, oil, natural gas, and biomass).
In the months following a pulse of NO x in the upper atmosphere, ozone production is stimulated causing a short-term warming. The corresponding reduction in CH 4 , which is an important ozone precursor, leads to a long-term reduction in ozone. Hydroprocessing of renewable oils to create a hydroprocessed renewable jet (HRJ) fuel.
Essam El-Hannouny, a principal mechanical engineer at the Department of Energy’s (DOE) Argonne National Laboratory, won a Technology Commercialization Fund (TCF) Award from DOE to expand his research on how a renewable alcohol-based biofuel can serve as a dual fuel to help decarbonize locomotive engines.
Researchers at North Carolina State University are developing an ozone-based pre-treatment technique (ozonolysis) to release sugars from the energy grass miscanthus for production into renewable fuels or chemicals with minimal generation of chemical waste streams and degradation of the carbohydrate components.
in 2018 (2000-2018 average year-over-year increase is 6.8%), continuing the increasing trend as they replace Ozone Depleting Substances (ODS) being phased out under the 1987 Montreal Protocol. Industry is already increasing the use of alternatives to petroleum diesel, including renewable diesel and biodiesel. tons per person to 10.7

The rail sector is the only transportation modality without significant emissions related development that is feasible in the near-term to eliminate ozone, smog and GHG emissions, OptiFuel says.
Biofuels such as ethanol, biodiesel, and renewable diesel can displace fossil fuels and reduce the amount of fossil-based CO 2 emissions released into the atmosphere. The percent of biodiesel and renewable diesel in the total diesel blend have shown a significant growth in recent years, going from 1% in 2012 to 18% in 2017.
The update sets funding priorities for the approximately $100 million in annual state funds under the Commission’s Alternative and Renewable Fuels and Vehicle Technology (ARFVT) Program, created by Assembly Bill 118. A minimum of 30% of the LNG dispensed for city vehicles will be from renewable sources. A-Z Bus Sales, Inc.
In the absence of major technological innovations or policy changes, the United States is unlikely to meet cellulosic biofuel mandates under the current Renewable Fuel Standard (RFS2) by 2022, according to a new report from the National Research Council. Economic effects.
These technologies include, but are not limited to, advanced aftertreatment and waste heat recovery; lean-burn plus lean-NO x emissions traps; integration of zero-emission miles technologies; further refinements in reducing friction and parasitic energy losses; and widespread utilization of renewable and natural gas and hydrogen blends.
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. The framework also includes the Cap-and-Trade Program, the Mobile Source Strategy, the Advanced Clean Car Program, the Renewables Portfolio Standard and the Low Carbon Fuel Standard.

The cap-and-trade program also works in concert with other measures, such as standards for cleaner vehicles, low-carbon fuels, renewable electricity and energy efficiency, and complements and supports California’s existing efforts to reduce smog-forming and toxic air pollutants.
The gas and hydrocarbons can then be treated and used or sold, avoiding the waste of natural resources that cannot be renewed. Those benefits include reductions in health effects related to fine particle pollution, ozone and air toxics, along with improvements in visibility.
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 Projected statewide light duty vehicle technology mix.

This is in contrast to the conventional mobile AC system, where the cabin air is directly cooled by the refrigerant HFC-134a, which is ozone safe but has a high GWP. The new SL-MAC system, which is testing the low-GWP refrigerants, is expected to increase vehicle energy efficiency. A2L and A2 are safety classifications.
Nevertheless, it is projected that even with the entire on-road fleet of heavy-duty vehicles compliant with the 2010 standards, upcoming National Ambient Air Quality Standards requirements for ozone attainment cannot be achieved in California’s worst air basins without further significant reductions in NO x emissions from heavy-duty fleets.
Recently, researchers have produced a new zeolite that is surprisingly stable and makes very little nitrous oxide from nitric oxide, a chemical that depletes ozone. This work was supported by the Department of Energy Office of Energy Efficiency and Renewable Energy. Ja Hun Kwak, Jong H. Lee, Sarah D. Burton, Andrew S. 201303498.
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. This research points to the importance of two fundamental and parallel trends in energy and the environment.
Markey of the Energy and Environment Subcommittee on Tuesday released a draft of far-reaching energy and climate legislation that targets job creation, promotes renewables and energy efficiency, and places limits on emissions of greenhouse gases. The draft establishes a Renewable Portfolio Standard—i.e., Partnering with the States.
WMO is also striving to improve weather and climate services for the renewable energy sector and to support the Green Economy and sustainable development. It also plays an important role in the destruction of the stratospheric ozone layer which protects us from the harmful ultraviolet rays of the sun. parts per billion.
The State’s organic waste should be put to beneficial use, such as for soil amendments/compost, electrical generation, transportation fuel, and pipeline-injected renewable natural gas. Organic wastes converted to biogas could supply enough renewable natural gas for about 2 million residential units.
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.” The more vehicles that switch to running on electricity, the better.
Mikhail Chester and Arpad Horvath inventoried on-road, rail, and air travel to determine energy consumption, greenhouse gas (GHG) emissions, and criteria air pollutant (CAP) emissions (excluding PM, lead, and ozone due to lack of data). 83% of rail passenger kilometers are performed by metropolitan systems (with Amtrak serving the remaining).
And the grid is getting cleaner and more renewable every year. 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.
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.
Eliminating ICE buses will go a long way toward making schools healthier for students. Fortunately, there are funding programs in place to help school boards transition away from ICE buses and help their students live healthier lives.
Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.
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.
What I do know, is how fossil fuel vehicles have contributed heavily to poor air quality in our towns and cities, damage to the environment, soil and water quality and have contributed to the depletion of the ozone layer! I’m passionate about renewables and have always been excited by futuristic technology.
