OSU team demonstrates Coal-Direct Chemical Looping for more efficient and low carbon coal heat release

Green Car Congress

An Ohio State University team has demonstrated the successful operation of Coal-Direct Chemical Looping (CDCL)—which chemically harnesses coal’s energy and efficiently contains the carbon dioxide produced before it can be released into the atmosphere. Hot iron and coal ash are left behind. 2 millimeters across.

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.

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.

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. CMD, coal mine drainage; TEP, trap-extract-precipitate. —Miranda et al. Miranda et al. —Jeff Bielicki.

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).

Lawrence Livermore publishes state-by-state energy/water Sankey diagrams

Green Car Congress

For the first time, Lawrence Livermore National Laboratory (LLNL) has published state-by-state energy and water Sankey diagrams in one location so that analysts and policymakers can find all the information they need in one place. General location of energy and water categories. Energy and water generally “flows” from left to right.

New catalyst opens door to CO2 capture in coal-to-liquids process

Green Car Congress

World energy consumption projections expect coal to stay one of the world’s main energy sources in the coming decades, and a growing share of it will be used in CT—the conversion of coal to liquid fuels (CTL). By 2020, CTL is expected to account for 15% of the coal use in China. —Wang et al.
