Center for Closing the Carbon Cycle (4C)

Establishing the scientific understanding required for the integrated capture of CO2 from dilute and/or dirty streams and conversion into useful carbon-based products

What's New?


Capturing CO2


Capturing CO2 from dilute industrial sources or air and turning into carbon feedstocks is critical for closing the anthropogenic carbon cycle. Our scientific discoveries will contribute to establishing carbon net-zero and net-negative technologies.

Who and Where

An interdisciplinary group of scientists and engineers from twelve universities and three national laboratories. Learn more about us under Researchers.


4C is a DOE-funded Energy Frontier Research Center (EFRC) that works collaboratively to advance our scientific goals and pursue enabling technologies. By working across disciplines and utilizing state-of-the-art instrumentation and experimental techniques, we will accelerate the advances needed to mitigate carbon emissions.
