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

Green Car Congress

A team of scientists from six institutions, including Akihiro Moriyoshi, Emeritus Professor Hokkaido University, have found that the presence of Trace Quantities of Organic Matter (TQOM) in modern concrete structures and asphalt pavements drive the deterioration of these structures. CT scans showing cracks in damaged concrete.

Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.

Study finds reduction of low-frequency noise from transition to electric buses improved residents’ health

Green Car Congress

Accompanying the lower noise levels from bus traffic was a reduction of fatigue, day time sleepiness and low mood, a study at the University of Gothenburg shows. The other half, who lived some distance away, made up the reference group. In the fall of 2019, all-electric buses were introduced on bus route 60 in Gothenburg.

International consortium working on new sensor technology to measure real-world, in-use vehicle emissions

Green Car Congress

As part of the Horizon 2020 research project CARES (City Air Remote Emission Sensing), an international research consortium is working on new contactless exhaust measurement methods that will enable municipalities to take emission-reducing measures. The aim is to detect the exhaust class of each individual vehicle using these measurements.

BP awards Colorado State University $5M to research technology for oil recovery from watered-out wells

Green Car Congress

Colorado State University has obtained a 5-year, $5-million grant from BP to study mechanisms involved with technology for oil recovery from “watered-out” wells. The pair will use a combination of laser experiments and nanofabrication approaches to examine the processes that occur in waterflooding an oilfield.

Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Researchers at Monash University in Australia have conducted a lifecycle analysis and net energy analysis (LCA/NEA) of a hypothetical large-scale solar-electrolysis plant for the production of green hydrogen. Taking IRENA’s REmap scenario as a reference, renewable hydrogen could deliver 5% of total final energy demand in 2050.

New nanostructured earth abundant metal catalysts rival platinum on a weight basis; diesel emissions treatment

Green Car Congress

A development in catalysis research by academics at the Universities of St Andrews and Newcastle could lead to new systems to treat diesel emissions. This is referred to as “chemistry at a point”. Catalysts are typically metallic nanoparticles—often platinum group metals—that are finely deposited upon a substrate.
