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.

Energy Vault to provide 1.6 GWh of gravity energy storage to support DG Fuels SAF projects

Green Car Congress

Energy Vault’s advanced gravity energy storage solutions are based on the proven physics and mechanical engineering fundamentals of pumped hydroelectric energy storage, but replace water with custom-made composite blocks, or “mobile masses”, which do not lose storage capacity over time. barrel per ton of feedstock.

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. —Wang et al.

Air France KLM signs 210M gallon SAF offtake agreement with DG Fuels

Green Car Congress

These changes eliminate the need for carbon sequestration and reduce the system’s feed-stock handling costs and complexity. The feed-stock reduction is achieved primarily by supplementing the process with oxygen and hydrogen produced by water electrolysis units that are powered by clean wind and solar generated electricity.

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

Green Car Congress

coal-cleaning plant in Alabama successfully reduced moisture from ultrafine coal waste. US coal producers each year discard large amounts of moisture-laden fines (small, coarse coal particles) that are typically deposited in containment ponds or impoundments as a slurry. of Johnson City, Tenn.,
