Portable sensors enable monitoring of pollution on smart phones; inferring pollution maps with greater granularity

Green Car Congress

Boxes represent pollution reading locations during that window. Computer scientists at the University of California, San Diego have built a portable pollution sensors that transmit transmit their air quality readings to smart phones, allowing users to monitor air quality in real time.

German-Chilean consortium investigating new ways of reducing arsenic in copper concentrates: ReAK

Green Car Congress

As well as copper, the excavated ore layers often also contain arsenic—a highly toxic, inorganic pollutant that poses a threat not only to human health but to the entire ecosystem. As a result, the amount of arsenic to be deposited will increase in the future, particularly given that there are currently no industrial uses for arsenic.

TERP awards Vision Industries and project partners $500K to support Texas’ first public hydrogen fueling station

Green Car Congress

The station, which is proposed to be fed from an existing hydrogen pipeline, will fuel port trucks and be publicly available for personal vehicles. In addition, the station offers the opportunity to provide fuel for future hydrogen equipment and vehicles used at other facilities, including warehouses and distribution facilities.

EPRI-NRDC report finds widespread vehicle electrification and a cleaner grid could lead to substantial cuts in GHG by 2050

Green Car Congress

The study analyzes two potential scenarios of the future electric sector, the “Base GHG” and “Lower GHG” scenarios. Considering the electric power sector and transportation sectors together, net emissions of pollutants leading to atmospheric ozone and fine particulate matter (PM 2.5 ) decrease in the electrification scenario.
