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.

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.

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. Methane is an especially potent greenhouse gas. degree Fahrenheit (less than 0.1

CICERO-led study finds global warming effect of leaked hydrogen almost 12x stronger than CO2

Green Car Congress

The open-access paper is published in Nature Communications Earth & Environment. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen.

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.

DOE awarding $6.5M to 9 large-scale Phase I pilot coal projects

Green Car Congress

This FOA, issued in August 2017, is a $50-million funding opportunity for projects supporting cost-shared research and development to design, construct, and operate two large-scale pilots to demonstrate transformational coal technologies. Some of these technologies are now ready to proceed to the large-scale pilot stage of development.

Rice lab’s flash Joule heating extracts rare earth elements from waste at high yields

Green Car Congress

The lab’s flash Joule heating process, introduced several years ago to produce graphene from any solid carbon source ( earlier post ), has now been applied to three sources of rare earth elements—coal fly ash, bauxite residue and electronic waste—to recover rare earth metals. —Deng et al. —James Tour.
