Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

high-temperature combustion processes and carbon-rich circumstellar environments portray a similar complexity as hydrocarbon-rich atmospheres of planets and their moons. The current study is the first demonstration of the so-called “radical propargyl self-reaction” under astrochemical and combustion conditions.

Berkeley Lab/U. Hawaii team provides direct experimental evidence for mechanism for PAH formation in combustion; cleaner fuels could result

Green Car Congress

Researchers at the Department of Energy’s Lawrence Berkeley National Lab (Berkeley Lab) and the University of Hawaii have provided direct experimental evidence for the validity of a proposed mechanism for the first step in the process that transforms gas-phase molecules into solid particles such as soot and other carbon-based compounds.

USDOT FTA announces $182M in Low-No grants for transit vehicles & facilities nationwide

Green Car Congress

The electric buses will replace CTA’s oldest diesel buses and reduce greenhouse gases in communities that have experienced air pollution and other environmental health hazards, improving public health and quality of life. By retrofitting the garage to service electric buses, the agency will also lower pollution in the surrounding community.

USC study shows promising potential for giant-kelp-based biofuel with depth-cycling approach

Green Car Congress

The National Research Council has indicated that generating biofuels from feedstocks such as corn and soybeans can increase water pollution. Farmers use pesticides and fertilizers on the crops that can end up polluting streams, rivers and lakes. Ginsburg et al. The study authors include Ignacio A. Navarrete, Diane Kim, David W.

Sandia Labs project team building fuel cell cold ironing system for deployment at Port of Honolulu in 2015

Green Car Congress

Ports have been a major source of water and air pollution in the US, but remained relatively unregulated until recent years. As ports have begun to expand and their impact on the environment has become more apparent, port operators face a variety of regulations. No one has ever built this kind of custom unit for this purpose.

Project shows maritime fuel cell generator can increase energy efficiency by up to 30% at part load; reliability and cost issues

Green Car Congress

Project goals were to demonstrate the use of the generator in the maritime environment, identify areas requiring additional research and development, analyze the business case, and address regulatory and other market barriers. A recent project demonstrated a 100 kW fuel cell generator with 72 kg of hydrogen storage for marine applications.
