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.

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.

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.

Weizmann Institute solar technology to convert CO2 into fuel; targeted for brown coal use in Australia

Green Car Congress

An Israeli-Australian venture will use solar technology developed at Israel’s Weizmann Institute of Science to reduce carbon dioxide emissions from the burning of brown coal. Jacob Karni, also makes it possible to dissociate water (H 2 O) to hydrogen (H 2 ) and oxygen (O 2 ) at the same time it dismantles the CO 2.

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 to award $32M for FEED studies for production of rare earths and critical minerals and materials from coal

Green Car Congress

Coal and coal production waste contain a wide variety of valuable rare earth elements that can be converted into clean energy technology components. The US currently has more than 250 billion tons of coal reserves, more than 4 billion tons of waste coal, and about 2 billion tons of coal ash at various sites across the country.

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.
