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

Green Car Congress

Scientists at the USC Wrigley Institute for Environmental Studies on Santa Catalina Island, working with private industry, report that a new aquaculture technique on the California coast significantly increases kelp growth, yielding four times more biomass than natural processes. The researchers used a depth-cycling approach—i.e.,

NPL novel reference electrode shows that cathode, not anode, is source of potential decay in PEM water electrolyzers

Green Car Congress

Scientists from the National Physical Laboratory (NPL) in the UK have developed a novel reference electrode for polymer electrolyte membrane water electrolyzers (PEMWEs) and used it to measure the electrochemical surface area (ECSA) of Pt catalysts in situ for the first time. Reference electrode configuration. Source: NPL.

Study links deterioration of concrete and asphalt to trace quantities of organic matter; diesel exhaust, windshield washer fluids

Green Car Congress

During their experiments, the scientists happened to notice that a strange odor developed when commercial cement was mixed with water. GBS, GHY, TMS, MS TSS and GR refer to different types of aggregates in the mortar. Organic matter in water accelerates deterioration of asphalt pavements.

Study finds perennial biofuel crops’ water consumption similar to corn

Green Car Congress

A study by a team from the Great Lakes Bioenergy Research Center (GLBRC) has found that perennial biofuel crops’ evapotranspiration does not differ greatly from corn. Hamilton uses the soil-water sensors to measure the rate of evapotranspiration occurring within each cropping system. —Hamilton et al.

Study finds association between air pollution, coronary atherosclerosis in Chinese population

Green Car Congress

The study was conducted on 8,867 Chinese adults aged 25 to 92. The findings, published in an open-access paper in JAMA Network Open , are significant because, while similar studies have been conducted in the US and Europe, this one is the first to investigate the connection between air pollution and coronary artery calcium in China.

Researcher urges more effort on assessment of land and water impacts of oil sands production; reference point for other unconventional fuels

Green Car Congress

Bitumen production from the Canadian oil sands provides a point of reference that could be used to observe and better manage the land and water impacts of a rapid transition to unconventional fuels, suggests Dr. Sarah Jordaan of the Energy Technology Innovation Policy Research Group, Department of Earth and Planetary Sciences, Harvard University.
