Scientists at ExxonMobil, the University of California, Berkeley, and the Lawrence Berkeley National Laboratory have discovered a new material that could capture more than 90% of carbon dioxide emissions from industrial sources.
The technology will help the energy company capture carbon emissions from natural gas power plants, using low-temperature steam, which requires less energy for the overall carbon capture process.
Laboratory tests indicate that the patent pending materials, known as tetraamine functionalized organic metal structures, capture carbon dioxide emissions up to six times more effectively than conventional amine based carbon capture technology.

By using less energy to capture and remove carbon, the material has the potential to lower the cost of technology and eventually support commercial applications.
By manipulating the structure of the organic metal frame material, the team of scientists and students demonstrated the ability to condense a surface area the size of a soccer field into just one gram of mass, about the same as a clip. made of paper, which acts as a sponge for carbon emissions.
ExxonMobil and its partners have been working collaboratively for eight years to develop this possible carbon capture solution that demonstrates stability in the presence of water vapor, without oxidation, allowing carbon dioxide to be captured from various sources, under various conditions.
“This innovative hybrid porous material has so far proven to be more effective, requires less heating and cooling, and captures more COtwo than current materials, “said Vijay Swarup, vice president of research and development at ExxonMobil Research and Engineering Company.
“Through collaborations with strong academic institutions and national laboratories such as UC Berkeley and the Lawrence Berkeley National Laboratory, we are developing a portfolio of low emission energy solutions. This provides another example of one of the many new materials that ExxonMobil is investigating to reduce COtwoin energy production. “
