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. The dompany is also working to develop a methodology to take stock of carbon units captured this way. In 2021, Nornickel extracted 41.2 mm) that looks like sand.

Cambridge researchers develop standalone device that makes formic acid from sunlight, CO2 and water

Green Car Congress

Researchers at the University of Cambridge, with colleagues at the University of Tokyo, have developed a standalone device that converts sunlight, carbon dioxide and water into formic acid, a carbon-neutral fuel, without requiring any additional components or electricity. —senior author Professor Erwin Reisner.

Molten carbonate electrolysis can produce a range of carbon nanomaterials, including graphene, from CO2 at high yield

Green Car Congress

Researchers from Huazhong University of Science and Technology in China and George Washington University in the US report in a new paper in the ACS journal Accounts of Chemical Research that a range of important carbon nanomaterials can be produced at high yield by molten carbonate electrolysis.

PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure). Heldebrant, D.,

8 Rivers announces 8RH2 CO2 Convective Reformer for ultra-low carbon hydrogen production from natural gas

Green Car Congress

8 Rivers Capital announced the development of the 8RH2 CO 2 Convective Reformer—a technology for the production of ultra-low carbon hydrogen from natural gas. It uses the oxy-combustion of carbon fuels and a high-pressure supercritical CO 2 working fluid in a highly recuperated cycle that captures all emissions by design.

Audi partnering with Climeworks on CO2 direct air capture and storage

Green Car Congress

The facility will filter 4,000 metric tons of carbon dioxide from the air and mineralize it underground. With direct air capture technology, carbon dioxide is extracted from the ambient air and air free of CO 2 is returned to the atmosphere. The carbon dioxide is thus permanently removed from the atmosphere.

Surrey team developing direct-air-capture CO2 to methanol process

Green Car Congress

Researchers at the University of Surrey (UK) are developing a process to capture carbon dioxide directly from the air and then use dynamic catalysis to create methanol—a valuable chemical that, made this way, could be carbon-negative. Its value could offset the cost of direct air capture.
