Single Pt atom catalysts show enhanced catalytic activity for water-splitting; potential to drive down electrolysis cost

Green Car Congress

A research team from University of Western Ontario, McMaster University and Beijing Computational Science Research Center has developed an effective synthesis method to produce isolated single platinum (Pt) atoms and clusters for use as catalysts for the hydrogen evolution reaction (HER) in water splitting to produce hydrogen.

Lifecycle Study Finds Algae as Bioenergy Feedstock Has Higher Environmental Impacts than Conventional Crops in Energy Use, GHG Emissions, and Water Use; The Importance of Using Waste Streams

Green Car Congress

Terrestrial bioenergy feedstock crops such as switchgrass, canola and corn have lower environmental lifecycle impacts than algae in energy use, greenhouse gas emissions, and water regardless of cultivation location, according to a new lifecycle assessment by researchers at the University of Virginia. 0.4 ± 0.05. 1.8 ± 0.58. 3.3 ± 0.86.

Study of 7 years of production data supports billion-ton biofuels feedstock estimate

Green Car Congress

South Dakota State University was the lead institution for the more than $20-million project which began in 2007. An article on environmental mapping of biomass resources in the continental United States will also be published in that issue. The partnership was funded by the US Department of Energy Bioenergy Technologies Office.

TU Graz researchers identify singlet oxygen as major cause of deleterious side reactions in Li-air batteries; suggested approach to counter

Green Car Congress

Researchers led by a team from Graz University of Technology (TU Graz) in Austria have shown that singlet oxygen ( 1 O 2 ) forms in the cathode of a Li–O 2 battery during discharge and from the onset charge, and that it is responsible for a major fraction of side products that cause fast ageing in the battery. —Mahne et al. 2017.36.

Taking the Measure of the Earthquake That Destroyed Tokyo

Cars That Think

But it paled in comparison to the destruction about to be unleashed. The violent vertical thrusts of the quake ruptured gas lines and water mains. It has to be manually reset after water mains and gas lines have been checked and, if necessary, repaired. Great Kanto Earthquake Memorial Museum The estimated 7.9-magnitude

New study finds key trade-off of algae-to-energy systems for transportation: excellent land use efficiency, but with mixed environmental burdens

Green Car Congress

The team earlier published LCA results finding that terrestrial bioenergy feedstock crops such as switchgrass, canola and corn have lower environmental life cycle impacts than algae in energy use, greenhouse gas emissions, and water regardless of cultivation location. environmental burdens (net energy use, water use, and GHG) per VKT.
