Researchers review risk to water resources from unconventional shale gas development in US

Green Car Congress

They identified four potential modes of water resource degradation: (1) shallow aquifers contaminated by fugitive natural gas (i.e., They identified four potential modes of water resource degradation: (1) shallow aquifers contaminated by fugitive natural gas (i.e., Credit: ACS, Vengosh et al.

MIT modeling study finds 52% of projected global population in 2050 will live in water-stressed areas

Green Car Congress

billion people in 2050 will live in water-stressed areas. The researchers also expect about 1 billion more people to be living in areas where water demand exceeds surface-water supply. A large portion of these regions already face water stress—most notably India, Northern Africa and the Middle East. Schlosser, C.A.,

Argonne releases updated WATER computer model to help bioenergy developers conserve water

Green Car Congress

The model , called Water Analysis Tool for Energy Resources or WATER, has users from more than 35 US states. This map depicts water availability by county; areas shown in orange are under higher levels of water stress. Water sustainability is becoming increasingly important when considering our energy future.

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

RIKEN researchers develop bio-inspired catalyst that splits water at neutral pH

Green Car Congress

Plants use photosynthesis to convert carbon dioxide and water into sugars and oxygen. The process starts in a cluster of manganese, calcium and oxygen atoms at the heart of a protein complex called photosystem II, which splits water to form oxygen gas, protons and electrons. —Yamaguchi et al.

Researchers develop free-standing nanowire mesh for direct solar water-splitting to produce H2; new design for “artificial leaf”

Green Car Congress

The mesh with BiVO 4 nanowire photoanode for water oxidation and Rh-SrTiO 3 nanowire photocathode for water reduction produces hydrogen gas without an electron mediator. When immersed in water with visible light irradiation (? ? In the present study, we developed a new architecture for direct solar water-splitting.
