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.,

Argonne LCA study finds many alternative fuels consume more water than petroleum and natural gas fuels

Green Car Congress

Researchers at Argonne National Laboratory have analyzed the water consumption for transportation fuels in the United States using an extended lifecycle system boundary that includes the water embedded in intermediate processing steps. Increases in population, energy and food demand now strain previously abundant sources of water.

IHS Markit: conventional oil & gas discoveries at lowest levels in 70 years; major rebound unlikely

Green Car Congress

Conventional oil and gas discoveries during the past three years are at the lowest levels in seven decades and a significant rebound is not expected, according to a new report by global business information provider IHS Markit. Drilling in frontier/emerging-phase basins declined by a similar amount. —Keith King. —Keith King.

Shell’s Cardamom development starts production; second major 2014 start-up in deep-water Gulf of Mexico

Green Car Congress

Production is now underway from the Cardamom development, the second major deep-water facility Shell has brought online in the US Gulf of Mexico this year, following the start-up of Mars B in February. Auger was Shell’s first deep-water tension-leg platform. —Marvin Odum.

NCSU team develops catalyst for thermal hybrid water-splitting and syngas generation with exceptional conversion; H2 gas and liquid fuels

Green Car Congress

Researchers at North Carolina State University have developed a highly effective new perovskite-promoted iron oxide redox catalyst for a hybrid solar-redox scheme they had proposed earlier for partial oxidation and water-splitting of methane. The addition of LSF significantly improves iron oxide’s activity, making it far more efficient.

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 (? ? 400 nm), the mesh produces hydrogen gas. Credit: ACS, Liu et al. Click to enlarge.

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.
