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 material is a hydrogel, a polymer network that naturally retains a lot of water.

RMIT researchers develop concept “proton flow battery”

Green Car Congress

RMIT University (Australia) researchers have developed a concept battery based on storing protons produced by splitting water—a reversible fuel cell with integrated solid proton storage electrode. The concept integrates a composite metal hydride–nafion electrode into a reversible proton exchange membrane (PEM) fuel cell.

Audi partnering with Climeworks on CO2 direct air capture and storage

Green Car Congress

Water from the Hellisheiði power plant then flows through the facility and transports the carbon dioxide roughly 2,000 meters below the surface of the Earth. The water returns to the cycle of the geothermal power plant. Furthermore, the rock in Iceland has the ideal composition for storing large amounts of CO 2.

Australian researchers develop new hybrid plasma electrocatalytic process to produce green ammonia

Green Car Congress

The method makes green ammonia from air, water and renewable electricity and does not require the high temperatures, high pressure and huge infrastructure currently needed to produce this essential compound. And we saw tragically in Beirut recently how potentially dangerous storing ammonium nitrate can be.
