Scientists set a record for the highest conversion rate of carbon dioxide at low temperatures with copper-modified indium oxide, signifying sustainable e-fuel.

With ever-worsening climate change, there is a growing need for technologies that can capture and use up the atmospheric CO 2 (carbon dioxide) and reduce our carbon footprint. One way to help address this growing carbon requirement is "carbon sequestration," or the transfer of CO 2 from the atmosphere into physical media like rock, soil or trees. In the current Algae to Carbon Emission Joint Undertaking, a research program funded by the Energy Department, the Oak Ridge National Laboratory (ORNL) and University of Tennessee, Knoxville, scientists have methodically built themselves 100-meter-high carbon dioxide sequestration ponds.

A surprisingly fast capture, although copper doesn't capture carbon.

For this new international partnership, "copper is incredibly inexpensive," explains Albiwan and his Oak Ridge colleague, Christopher Del Palma of the DOE's Argonne National Laboratory. "One physical solution is to use copper to bond with metal resources like aluminum, which has low but higher energy-to-weight ratios than copper. So you could continually do the exchange via the environment."

"It's not going to be as efficient a way to capture CO 2 over a longer timescale," says Mohamad-Ali Tany, an ORNL geophysicist who coordinated the Algae to Carbon Emission/DoE collaboration. "But it's a faster and more efficient technology. At this point, you could do this on demand, without needing to truck the fuel to the site."

Earlyy preliminary: In the lead up to the incentive program, arsenic, phosphorus and cobalt and their associated elements were all reportedly funneled from ponds to screen This is just a preliminary pixelated representation of As of now, the scientific and technical objectives of the Algae to Carbon Emission Joint Undertaking are as follows:a. The objective is to develop the laboratory tools, hardware and structures necessary to capture atmospheric CO 2 and also help increase the efficiency of this capture process, so immense increases in fossil fuel closure can be achieved while having associated water and other human impacts should be minimized.b. A key performance of this joint achievement is the ability to validate the process at near-UT climate over a 10th of a kilometer resolution.c. The pooled research community needs to demonstrate the capture of trace metals such as arsenic, copper, and iron to a reasonable degree of success; cobalt to an equally hopeless degree.d. Include a description of a feasibility study of the costs associated with a full scale greenhouse gas encirclement.(done)E. Monitor the costs and operational performance of the collaborative research community's research on the topic over a five-year window.(17% projects completed to date)
