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.

Baker Institute-led group to develop nationwide protocol for paying ranchers and farmers to store carbon

Green Car Congress

Rice’s Baker Institute for Public Policy has initiated a working group to develop a United States protocol for paying ranchers and farmers to store carbon in their soil. Robin Rather, CEO of Austin-based Collective Strength, is the group’s facilitator. Baker III and Susan G. —Kenneth Medlock. —Jim Blackburn.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. In theory, the decomposition potential of water is 4.27

ARPA-E awarding $39M to 16 projects to grow the domestic critical minerals supply chain

Green Car Congress

First, an electric potential will be applied to water to simultaneously produce acidity and alkalinity. The University of Texas at Austin. million tonnes of CO 2 per year will be sequestered in mine tailings that are permanently and safely stored with a decrease of 100 kg of CO 2 equivalent per tonne of ore processed.

Researchers combining CO2 storage and geothermal energy production

Green Car Congress

Between five and ten percent of the water injected in these systems is lost as it travels through the pore spaces. As this happens, more water must be added, perhaps from municipal sources that have little to spare. Their work has shown that supercritical CO 2 is better than water at mining heat from the subsurface.

Duke study: serpentinized rock in oceans may be large, overlooked source of free hydrogen gas

Green Car Congress

The new model calculates the amount of free hydrogen gas produced and stored beneath the seafloor based on a range of parameters—including the ratio of a site’s tectonic spreading rate to the thickness of serpentinized rocks that might be found there. Worman, postdoc at UT Austin, who led the study while a doctoral student at Duke.
