Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. Schematic overview of the processes by which aviation emissions and increased cirrus cloudiness affect the climate system. Aviation accounts for 3.5% —Lee et al.

Researchers develop titanium and copper heterostructured photocatalyst for conversion of CO2 into CH4

Green Car Congress

Under illumination for 6 hours, the optimized reduced titania-Cu 2 O photocatalyst enables 0.13% photoreduction of highly diluted CO 2 with water vapors to 462 nmol g ?1 What if we drew inspiration from photosynthesis, the process by which plants use sunlight to convert CO2 and water into useful chemicals? —Prof In.

BMW i Ventures invests in Prometheus Fuels; CO2 air-capture and conversion to carbon-neutral gasoline

Green Car Congress

BMW i Ventures has invested in Prometheus Fuels ( earlier post ), a company removing CO 2 from the air and turning it into zero-net carbon gasoline that it will sell at gas stations, at a price that competes with fossil fuels, starting as early as this year. The separation of ethanol and other fuel products from water.

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.

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

Stuart Licht have demonstrated the first facile high-yield, low-energy synthesis of macroscopic length carbon nanotubes (CNTs)—carbon nanotube wool—from CO 2 using molten carbonate electrolysis ( earlier post ). The most compact form of captured carbon is through its transformation to solid carbon.

New polymer membrane efficiently removes carbon dioxide from mixed gases; high permeability and selectivity

Green Car Congress

A team of researchers from North Carolina State University, SINTEF in Norway and the Norwegian University of Science and Technology, has developed a polymer membrane technology that removes carbon dioxide from mixed gases with both high permeability and high selectivity. A paper on their work is published in the journal Science.
