Virtual forum on near-roadway air pollution highlights health effects

Air pollution has long been a public health concern, and the spike in pollutants often detected near roadways is receiving closer attention from researchers and policymakers. NIEHS helped broaden public understanding of these impacts in the July 10 virtual forum, “Near-Roadway Pollution and Health,” moderated by Gwen Collman, Ph.D., director of the NIEHS Division of Extramural Research and Training (DERT). “Our presenters today come from the evolving robust network of air pollution researchers supported by NIEHS,” she said.

Fuel Cells & Vehicles: Hydrogen Vehicle Testing facility

In November 2002, the U.S. Environmental Protection Agency (EPA) certified the National Vehicle and Fuel Emissions Laboratory (NVFEL) as their first lab for testing hydrogen fuel cell vehicles. The agency also certified the 2003 Honda FCX as the first fuel cell vehicle. The tests were limited to fuel economy issues only as the vehicle is said to be emission free. Read More

Fuel Cells and Vehicles

The EPA is playing a leading role in the Federal Government’s growing efforts to accelerate the development of fuel cell technology, especially for vehicle applications. A collaborative effort between the EPA, Daimler Chrysler, and UPS is under way to put several zero-emission, hydrogen powered package delivery vehicles into commercial service in Michigan. Much of the testing conducted is performed at the National Vehicle and Fuel Emissions Laboratory (NVFEL) in Ann Arbor, Michigan, where many of the testing protocols to handle hydrogen fuel were developed.

Hydrogen generation from plasmatron reformers: A promising technology for NOx adsorber regeneration and other automotive applications

Plasma Fuel Converters increase the efficiency of fuel in vehicles through the injection of electrical current. This document focuses on the benefits of using plasma reformers for nitrogen oxide emission reductions. The document summarizes laboratory and vehicle tests of plasmatrons while attempting to maximize nitrogen oxide reduction and efficient fuel use. From the Plasma Science and Fusion Center, Department of Mechanical Engineering and Sloan Automobile Lab. Read More

Aftertreatment of Diesel Vehicle Emissions Using Compact Plasmatron Fuel Converter-Catalyst Systems

Plasma Fuel Converters convert carbon fuel to rich hydrogen gas by electrifying fuel in an engine. This increases the efficient burning of the fuel, and reduces the resulting pollutants. This document summarizes the benefits plasma converters can have for lower diesel fuel emissions, especially if combined with catalysts that absorb particulate pollutants and nitrogen oxides. From the Plasma Science and Fusion Center, Massachussetts Institute of Technology Read More

Sources of Emission Reductions: Evidence from U.S. SO2 Emissions from 1985 through 2002

This paper describes database studies that have examined where the greatest emission reductions in sulfur dioxide have occurred over the past twenty years. Specifically, the paper examines whether reductions have come from retrofits of existing power generation plants, or replacement of old plants with new generating capacity. The paper finds that the greatest reductions have been gained through plant retrofits, though new plants have also displace potential emissions from the generation facilities they replaced.
