Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The amount of methane released into the atmosphere as a result of coal mining is likely approximately 50% higher than previously estimated, according to research presented at the recent annual meeting of the American Geophysical Union. The authors point out that less coal production doesn’t translate to less methane.

Converting Coal Power Plants to Nuclear Gains Steam

Cars That Think

On a planet aspiring to become carbon neutral, the once-stalwart coal power plant is an emerging anachronism. It is true that, in much of the developing world, coal-fired capacity continues to grow. But in every corner of the globe, political and financial pressures are mounting to bury coal in the past.

SRI developing process for co-gasification of methane and coal to produce liquid transportation fuels; negligible water consumption, no CO2

Green Car Congress

Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. In conventional CTL approaches, energy is supplied by burning a portion of the coal feed, which then produces carbon dioxide.

Los Angeles takes steps to transition out of coal-fired power earlier than required by state law

Green Car Congress

The Los Angeles Department of Water and Power (LADWP) has taken steps to transition out of the use of coal-fired electricity earlier than mandated by California state law. LADWP currently owns a 21% interest in the 2250 megawatt (MW) Navajo Generating Station, receiving 477 MW of coal-fired power from the plant.

NETL researchers create MOF-based luminescent sensor to detect aluminum impurities in rare earth element sources

Green Car Congress

Aluminum is a critical element used in thousands of important products, but it can often interfere with quick and effective extraction of valuable rare earth elements (REEs) from coal waste byproducts. The film emits blue light in the presence of water and becomes significantly more intense in the presence of aluminum ions.

Borla Performance Industries developing muffler/membrane unit for exhaust water extraction with ORNL nanopore membrane technology

Green Car Congress

Borla will combine this with its diesel exhaust technology to create a low-cost, novel system that doubles as a device to extract potable water from diesel and other internal combustion exhaust. The heat recovered could serve to preheat boiler feed water, thus providing an energy savings.
