Researchers create salts for cheap and efficient CO2 capture; mimicking methane hydrate

Green Car Congress

The salt-based, clathrate structure utilizes low energy, physisorption processes while capturing CO 2 without water or nitrogen interference, opening a promising venue for future carbon capture and storage technologies through rapid CO 2 solidification. The discovery introduces a new way of storing and transporting carbon dioxide as a solid.

Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

The nanostructured photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied with a faradaic efficiency of 30% and excellent stability. The researchers believe this new type of photoelectrode is not only cheap to produce, but can also be recreated on a larger scale for mass and worldwide use.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. Earlier post.). simulated sunlight. constructing a simple, stand-alone device composed of.

Oleophobic hydrophobic magnetic sponge selectively soaks up oil, sparing water and wildlife

Green Car Congress

A Northwestern Engineering-led team has developed a highly porous smart sponge that selectively soaks up oil in water. Currently used solutions include burning the oil, using chemical dispersants to breakdown oil into very small droplets, skimming oil floating on top of water and/or absorbing it with expensive, unrecyclable sorbents.

Swansea team develops faster, greener way of producing carbon spheres

Green Car Congress

A fast, green and one-step method for producing porous carbon spheres—a component for carbon capture technology and for new ways of storing renewable energy—has been developed by Swansea University researchers. storage and conversion, catalysis, gas adsorption and storage, drug and enzyme delivery, and water treatment.

Fraunhofer suggests e-scooters as application for its magnesium hydride paste hydrogen storage technology

Green Car Congress

Fraunhofer’s POWERPASTE releases hydrogen on contact with water. POWERPASTE stores hydrogen in a chemical form at room temperature and atmospheric pressure to be then released on demand, said Dr. Marcus Vogt, research associate at Fraunhofer IFAM. It has a hydrogen capacity of about 10 mass-% (i.e. 10 kg POWERPASTE ? 1 kg hydrogen).

USC team develops novel organic redox flow battery for large-scale energy storage

Green Car Congress

Scientists at USC have developed a novel water-based Organic Redox Flow Battery (ORBAT) for lower cost, long lasting large-scale energy storage. ORBAT employs two different water-soluble organic redox couples on the positive and negative side of a flow battery. Schematic of ORBAT. Click to enlarge. —Yang et al.
