A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The UT Austin technique is aimed at the latter.

LANL and WSU researchers develop high-performance anion exchange membrane water electrolyzer with nickel-iron catalyst

Green Car Congress

Currently the most popular system used for water electrolysis for hydrogen production relies on precious metals as catalysts. The research team worked to solve this problem by splitting water under alkaline, or basic, conditions with an anion exchange membrane electrolyzer. V without a corrosive circulating alkaline solution.

Sunfire, Fraunhofer, partners launch project to scale alkaline AEM electrolysis

Green Car Congress

Technologies such as pressurized alkaline or high-temperature electrolysis are already being installed in industrial environments. AEM electrolysis combines the respective technical advantages of polymer exchange membrane electrolysis (PEM) and alkaline electrolysis (AEL). In addition, porous transport layers (PTL) are optimized.

KAUST team develops process for tunable membranes for energy-efficient crude oil fractionation

Green Car Congress

Researchers at King Abdullah University of Science and Technology (KAUST) have developed a process for fabricating polytriazole membranes with 10-nanometer-thin selective layers containing subnanometer channels. I'm always looking for polymers that can take challenges that are not possible with a very simple membrane. Suzana Nunes.

Study finds automobile tires are a potential source of carcinogenic dibenzopyrenes to the environment

Green Car Congress

A new study by researchers from Stockholm University concludes that automobile tires may be a potential previously unknown source of carcinogenic dibenzopyrenes—a type of high molecular weight polycyclic aromatic hydrocarbon (PAH)—to the environment. 60% rubber polymers; 20?35% kg dibenzopyrenes, respectively.

Study shows a much cheaper catalyst can generate hydrogen in a commercial electrolyzer

Green Car Congress

Researchers at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have shown for the first time that a low-cost, non-precious metal cobalt phosphide (CoP) catalyst catalyst can split water and generate hydrogen gas for hours on end in the harsh environment of a commercial device.
