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.

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.

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.

Successful demonstration of advanced hyperbaric centrifuge technology for recovering fine coal particles from waste slurries

Green Car Congress

A full-scale test of advanced hyperbaric centrifuge technology at a Jim Walter Resources Inc. coal-cleaning plant in Alabama successfully reduced moisture from ultrafine coal waste. Coal recovery from the sludge was greater than 97%. Virginia Tech subsequently sublicensed the technology to Decanter Machine Inc.,

NETL publishes review of safety challenges of production, transportation and storage of hydrogen

Green Car Congress

It’s our hope that this report will serve as a valuable resource for stakeholders in charting future hydrogen projects and assist in building safe, sustainable bulk hydrogen production and power generation infrastructure. Hydrogen can be extracted from different sources such as fossil fuels, biomass, waste plastics and water.

Argonne LCA study finds many alternative fuels consume more water than petroleum and natural gas fuels

Green Car Congress

Researchers at Argonne National Laboratory have analyzed the water consumption for transportation fuels in the United States using an extended lifecycle system boundary that includes the water embedded in intermediate processing steps. Increases in population, energy and food demand now strain previously abundant sources of water.
