Israeli team develops decoupled PEC water-splitting system for centralized production of H2

Green Car Congress

Researchers in Israel have designed a separate-cell photoelectrochemical (PEC) water-splitting system with decoupled hydrogen and oxygen cells for centralized hydrogen production. A paper describing their system is publishedin the journal Joule. The hydrogen cell contains the cathode, and it is physically separated from the oxygen cell.

U Oregon team advances effectiveness of catalytic water dissociation in bipolar membranes

Green Car Congress

Researchers at the University of Oregon have advanced the effectiveness of the catalytic water dissociation reaction in bipolar membranes. The technology behind bipolar membranes, which are layered ion-exchange polymers sandwiching a water dissociation catalyst layer, emerged in the 1950s. —Oener et al.

New polymer membrane efficiently removes carbon dioxide from mixed gases; high permeability and selectivity

Green Car Congress

A team of researchers from North Carolina State University, SINTEF in Norway and the Norwegian University of Science and Technology, has developed a polymer membrane technology that removes carbon dioxide from mixed gases with both high permeability and high selectivity. A paper on their work is published in the journal Science.

Toshiba’s new large-scale production technology for electrolysis electrodes cuts iridium use to 1/10

Green Car Congress

P2G uses electrolysis of water to convert renewable energy into hydrogen, for storage and transportation to where it is needed. Polymer Electrolyte Membrane (PEM) electrolysis is seen as a highly promising conversion method, as it is reacts rapidly to power fluctuations and is highly durable.

Researchers split water by altering photosynthetic machinery in plants; semi-artificial photosynthesis

Green Car Congress

They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and manmade technologies. A new paper, published in Nature Energy , outlines how the researchers at the Reisner Laboratory in Cambridge developed their platform to achieve unassisted solar-driven water-splitting.

New one-pot conversion of CO2 to polycarbonate copolymers

Green Car Congress

Researchers at Texas A&M have developed a two-step, one-pot conversion of CO 2 and epoxides (highly reactive compounds with a three-membered ring made of two carbon atoms and one oxygen atom) to polycarbonate block copolymers that contain both water-soluble and hydrophobic regions and can aggregate into nanoparticles or micelles.

Researchers use multifunctional co-solvent pair to uncover molecular principles of biomass breakdown for conversion to transportation fuels

Green Car Congress

Plant cell walls resist chemical or biological degradation, making the breakdown of lignocellulosic biomass into renewable chemical precursors for conversion into chemicals and transportation fuels challenging and costly. Co-solvents THF and water cause lignin to dissociate from itself and cellulose, expanding into a random coil.
