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. As a waste, tailings are stored in designated storage facilities called tailing dams. In 2021, Nornickel extracted 41.2 mm) that looks like sand.

Audi partnering with Climeworks on CO2 direct air capture and storage

Green Car Congress

The CO 2 molecules react through natural mineralization processes with the basalt rock and are converted to carbonates over a period of several years, thus permanently storing the CO 2 underground. Furthermore, the rock in Iceland has the ideal composition for storing large amounts of CO 2.

New electrocatalyst converts CO2 into ethanol, acetone, and n-butanol with high efficiency

Green Car Congress

Excess energy produced by photovoltaics and wind energy could be stored through the electrocatalytic production of fuels from CO 2. Conversion into liquid fuels would be advantageous because they have high energy density and are safe to store and transport. These could then be burned as needed.

Researchers demonstrate efficient electrochemical reduction of CO2 to C2+ alcohols

Green Car Congress

When powered by renewable solar or wind energy sources, the electrocatalytic CO 2 reduction reaction (CO 2 RR) is a promising approach to produce value-added chemicals/fuels and store renewable energy to achieve the goal of net-zero-emissions. C 2+ alcohols are desirable due to their high energy densities and large global market capacities.
