University of Houston team demonstrates new efficient solar water-splitting catalyst for hydrogen production

Green Car Congress

Researchers from the University of Houston (UH) have developed a cobalt(II) oxide (CoO) nanocrystalline catalyst that can carry out overall water splitting with a solar-to-hydrogen efficiency of around 5%. The generation of hydrogen from water using sunlight could potentially form the basis of a clean and renewable source of energy.

New inexpensive catalyst for conversion of CO2 to CO could help with storage of renewable energy

Green Car Congress

Researchers at the University of Delaware have developed an inexpensive bismuth?carbon CO can then be reacted with H 2 O via the water?gas As such, development of Bi-based cathodes for conversion of CO 2 to CO would represent an important development for the fields of CO 2 electrocatalysis and renewable energy conversion.

Duke team develops new core-shell copper nanowire catalyst for efficient water oxidation for solar fuels

Green Car Congress

A transparent film of copper nanowires was transformed into an electrocatalyst for water oxidation by electrodeposition of Ni or Co onto the surface of the nanowires. Water oxidation (2H 2 O → O 2 + 4 e- + 4H + ) is a key step for converting solar energy into chemical fuels. Chen et al. Click to enlarge. A team led by Benjamin J.

University of Texas researchers develop new solar photoelectrosynthetic process to convert CO2 to methanol

Green Car Congress

Researchers from The University of Texas at Arlington are developing a new process for photoelectrosynthesis of methanol—the conversion of carbon dioxide to methanol using sunlight and hybrid CuO–Cu 2 O semiconductor nanorod arrays. In the lab, they submerged those rods in a water-based solution rich in CO 2.

HELMETH project targeting >85% efficiencies for power-to-gas; high-temperature electrolysis

Green Car Congress

The HELMETH (“Integrated High-temperature ELectrolysis and METHanation for Effective Power to Gas Conversion”) project, coordinated by Karlsruhe Institue of Technology (KIT) is targeting power-to-gas (PtG) system efficiencies of more than 85% through better synergies with existing process steps. Power-to-gas (e.g., Power-to-gas (e.g.,

Study projects regional climate effects from ramping up Brazil sugarcane production

Green Car Congress

Conversion of large swaths of Brazilian land for sugar plantations will help the country meet its needs for producing cane-derived ethanol, but it also could lead to regional climate effects, according to a team of researchers from Arizona State University, Stanford University and the Carnegie Institution for Science.

Nanocatalysts for in situ bitumen upgrading can produce higher quality liquid with lower environmental and cost impacts

Green Car Congress

Researchers at the University of Calgary have developed Ni?W?Mo Current heavy oil and bitumen production processes are high-energy and water-intensive and, consequently, have significant environmental footprints because of the production of gaseous emissions such as CO 2 and generating huge amounts of produced water.
