Nornickel investigating using mining tailings to capture and store CO2

Green Car Congress

Russia-based Norilsk Nickel (Nornickel)—the world’s largest nickel producer—is studying the potential for mining tailings to capture and store CO 2. Ore mining and concentration results in waste rock, or tailings—fine-grained rock (less than 0.4 In 2021, Nornickel extracted 41.2 mm) that looks like sand.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. Because so much energy is lost turning steam back into water in the Rankine cycle, at most a third of the power in the steam can be converted into electricity.
