Twelve and LanzaTech successfully convert CO2 to ethanol

Green Car Congress

Our process aims to rebalance the overabundance of carbon in our environment and instead reuse it for meaningful applications. This approach is highly scalable and could ultimately produce ethanol at an industrial scale, while simultaneously eliminating CO 2 emissions. —LanzaTech CEO Dr. Jennifer Holmgren.

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.

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.

Researchers tailor catalyst microenvironments to enhance CO2 electroreduction to multicarbon products

Green Car Congress

Our group has found that you can do various tricks with the local environment of the catalyst to provide that selectivity. In previous studies, the researchers had established the precise conditions that gave the best electrical and chemical environment for creating commercially interesting carbon-rich products.

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

Green Car Congress

Electron microscopy experiments at the Molecular Foundry confirmed that cuprous oxide quickly oxidizes or corrodes within minutes of exposure to light and water. We knew it was unstable—but we were surprised to learn just how unstable it really is. —Francesca Toma. This demonstrates that hydroxides contribute to corrosion.

Galvanic, IBAT testing proves Smackover brine is DLE compatible

Green Car Congress

The catch is identifying lithium that can be harvested economically and in a way that doesn’t harm the environment. Besides fresh water, no other chemicals were required in the IBAT process, whereas other DLE operators add acids, bases or both to adjust the pH of the brine through their DLE processes. We can find the lithium.
