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.

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

Green Car Congress

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. DGF replaces the coal gasification used by others with biomass gasification and natural gas reforming. —Christopher J.

DOE to award up to $36M for design and testing of advanced carbon capture technologies for coal-fired power generation

Green Car Congress

The US Department of Energy (DOE) will award up to $36 million ( DE-FOA-0001791 ) to continue the development of carbon capture technologies to either the engineering scale or to a commercial design, with an eye to reducing fossil fuel power plant emissions. Engineering design is to cover both the carbon capture process and balance of plant.

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

Green Car Congress

Hydrogen can be extracted from different sources such as fossil fuels, biomass, waste plastics and water. However, hydrogen does have several safety concerns that must be contended with through careful engineering design and diligent operations.

WVU opens new research facility to extract valuable rare earth elements from acid mine drainage

Green Car Congress

West Virginia University (WVU) researchers are opening a new facility to capture rare earth elements (REEs) from acid mine drainage (AMD) from coal mining. Conventional rare-earth recovery methods require an expensive, difficult and messy extraction process that generates large volumes of contaminated waste. —Paul Ziemkiewicz.
