Study finds high sodium bicarbonate concentrations in water from coal-bed natural gas production harms aquatic life; water treatment can mitigate effects

Green Car Congress

Produced water from coal-bed natural gas (CBNG) production may contain sodium bicarbonate (NaHCO 3 ) at concentrations that can harm aquatic life, according to a new study by the US Geological Survey; Montana Fish, Wildlife and Parks; the Bureau of Land Management and the US Environmental Protection Agency.

OSU team develops process to clean coal mine drainage and extract rare earth elements

Green Car Congress

Researchers at The Ohio State University have developed a novel process to clean coal mine drainage and extract rare-earth elements from it. Coal mine drainage (CMD) impairs tens of thousands of kilometers of U.S. waterways each year, in part with the leaching of low concentrations of rare earth elements (REEs). Miranda et al.

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

While coal use causes warming through emission of heat-trapping carbon dioxide, it also releases comparatively large amounts of sulfates and other particles that, although detrimental to the environment, cool the planet by blocking incoming sunlight. —Tom Wigley. Methane is an especially potent greenhouse gas. degree Celsius).

EIA: US electricity generation from coal and natural gas both increased with summer heat

Green Car Congress

In August 2012, coal produced 39% of US electricity, up from a low of 32% in April 2012, when the natural gas share of generation equaled that of coal. The August coal share of generation is still notably lower than the 50% annual average over the 1990-2010 period. Other plants use PRB coal transported by rail.
