SLB introduces low-carbon alternative for well construction cement that eliminates up to 85% of embodied CO2

Green Car Congress

Cement provides structural support; functions as a barrier that helps prevent corrosion of the steel casing; and blocks oil, gas, or water from traveling through the annulus (the space between the wellbore and the casing). This barrier also protects fresh water aquifers and helps prevent the inflow of undesirable hydrocarbons.

Twelve and LanzaTech successfully convert CO2 to ethanol

Green Car Congress

Carbon transformation company Twelve and biotechnology company LanzaTech have transformed CO 2 emissions into ethanol as a part of an ongoing research and development partnership. Our process aims to rebalance the overabundance of carbon in our environment and instead reuse it for meaningful applications.

Researchers tailor catalyst microenvironments to enhance CO2 electroreduction to multicarbon products

Green Car Congress

However, to be commercially viable, the process needs to be improved to yield a higher amount of desirable carbon-rich products. Our group has found that you can do various tricks with the local environment of the catalyst to provide that selectivity. earlier post ). Credit: Berkeley Lab). —Alexis Bell.

DOE announces $11.5M in Phase 1 funding for carbon capture and storage program; ARPA-E FLECCS

Green Car Congress

million in funding for 12 projects as part of Phase 1 of the Advanced Research Projects Agency-Energy’s (ARPA-E’s) FLExible Carbon Capture and Storage (FLECCS) program. The post-combustion outlet gas is more easily separated into water and CO 2 to the pipeline, thereby lowering the electricity costs of grids with high levels of VRE.

Researchers develop new stable artificial photosynthesis device to produce ethylene and hydrogen from sunlight and CO2

Green Car Congress

A research team has developed a new artificial photosynthesis device component with remarkable stability and longevity as it selectively converts sunlight and carbon dioxide into two promising sources of renewable fuels: ethylene and hydrogen. We knew it was unstable—but we were surprised to learn just how unstable it really is.

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

Green Car Congress

The study was published in the journal Atmospheric Environment. Net positive RF (warming) contributions arise from CO 2 , water vapor, NO x , and soot emissions, and from contrail cirrus (consisting of linear contrails and the cirrus cloudiness arising from them). Aviation accounts for 3.5% Pitari, M.J. Prather, R. Sausen, L.J.

PSI team demonstrates direct hydrocarbon fuel production from water and CO2 by solar-driven thermochemical cycles

Green Car Congress

By utilizing a redox material such as ceria (CeO 2 ) as a reactive medium, STCs can produce hydrogen and carbon monoxide—i.e., syngas—from water and CO 2. Schematic illustration of direct hydrocarbon (C x H y O z ) formation from water and carbon dioxide during the reoxidation of reduced ceria doped with a catalyst (Cat.).
