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.

Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The amount of methane released into the atmosphere as a result of coal mining is likely approximately 50% higher than previously estimated, according to research presented at the recent annual meeting of the American Geophysical Union. The authors point out that less coal production doesn’t translate to less methane.

Equinor and RWE to develop hydrogen-fired power plants in Germany, Norway-to-Germany hydrogen pipeline

Green Car Congress

The partners aim to replace coal-fired power plants with hydrogen-ready gas-fired power plants in Germany, and to build production of low carbon and renewable hydrogen in Norway that will be exported through pipeline to Germany. Germany has an ambition to phase out all coal fired power plants by 2030. Markus Krebber, CEO of RWE.

RMI report maps out pathway for zero-carbon steel industry in China

Green Car Congress

A new report from RMI (Rocky Mountain Institute) finds that it is technically and economically feasible for China’s steel industry to decarbonize by 2050 through demand reduction, steel recycling and switching to green routes. This makes the steel industry the country’s second-largest carbon emitting sector behind power generation.

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.

BNEF: steel industry set to pivot to hydrogen in green push; additional $278B for clean capacity and retrofits

Green Car Congress

Steel is responsible for around 7% of man-made greenhouse gas emissions every year and is one of the world’s most polluting industries. Government and corporate net-zero commitments are pushing the steel industry to cancel out its emissions by 2050. The steel industry cannot afford to wait for the 2040s to start its transition.
