Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

A study by a team of researchers from Technische Universität Berlin (TUB) and Fritz-Haber-Institut der Max-Planck-Gesellschaft has found that direct seawater splitting for hydrogen production has substantial drawbacks compared to conventional water splitting and offers almost no advantage. Additionally, H 2 O is needed for water splitting.

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 greatest challenge is to develop a suitable technology for large scale and cost effective solar fuel production to compete with fossil fuel.

Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Stanford researchers, with a colleague from King Fahd University of Petroleum and Minerals, have developed a simple and environmentally sound way to make ammonia with tiny droplets of water and nitrogen from the air. Water microdroplets are the hydrogen source for N 2 in contact with Fe 3 O 4. The conversion rate reaches 32.9 ± 1.38

PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

Researchers at the Department of Energy’s Pacific Northwest National Laboratory have developed a new method to convert captured CO 2 into methane, the primary component of natural gas. Different methods for converting CO 2 into methane have long been known. Using EEMPA instead reduces the energy needed to fuel such a reaction.

Cambridge researchers develop standalone device that makes formic acid from sunlight, CO2 and water

Green Car Congress

Researchers at the University of Cambridge, with colleagues at the University of Tokyo, have developed a standalone device that converts sunlight, carbon dioxide and water into formic acid, a carbon-neutral fuel, without requiring any additional components or electricity. —senior author Professor Erwin Reisner.

EU project HyFlexFuel converted sewage sludge and other biomasses into kerosene by hydrothermal liquefaction (HTL); SAF

Green Car Congress

Cost-effectiveness: It can produce advanced biofuels, from marine fuels to kerosene, potentially at lower cost than most competing renewable fuel pathways. Under these conditions, biomass is converted into a crude bio-oil, which is separated from the process water behind the reactor.

EPFL team develops low-cost water splitting cell with solar-to-hydrogen efficiency of 12.3%

Green Car Congress

Michael Grätzel at EPFL (Ecole Polytechnique Fédérale de Lausanne) in Switzerland has developed a highly efficient and low-cost water-splitting cell combining an advanced perovskite tandem solar cell and a bi-functional Earth-abundant catalyst. Splitting water requires an applied voltage of at least 1.23 V and up to 1.5
