Scientists from ExxonMobil, University of California, Berkeley
and Lawrence Berkeley National Laboratory have discovered a new
material that could capture more than 90 percent of CO2 emitted
from industrial sources, such as natural gas-fired power plants,
using low-temperature steam, requiring less energy for the overall
carbon capture process.

Laboratory tests indicate the patent-pending materials, known as
tetraamine-functionalized metal organic frameworks, capture carbon
dioxide emissions up to six times more effectively than
conventional amine-based carbon capture technology. Using less
energy to capture and remove carbon, the material has the potential
to reduce the cost of the technology and eventually support
commercial applications.
By manipulating the structure of the metal organic framework
material, the team of scientists and students demonstrated the
ability to condense a surface area the size of a football field,
into just one gram of mass – about the same as a paperclip – that
acts as a sponge for CO2. Results of the research were published
today in the international peer-reviewed journal, Science.
“This innovative hybrid porous material has so far proven to be
more effective, requires less heating and cooling, and captures
more CO2 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 labs like UC Berkeley and the Lawrence Berkeley National
Laboratory, we are developing a portfolio of lower-emissions energy
solutions. This provides yet another example of one of the many new
materials ExxonMobil is researching to reduce CO2 in the production
of energy,” said Swarup.
ExxonMobil’s team, led by senior research associate Simon
Weston, along with UC Berkeley’s professor Jeffrey Long and his
team of faculty and students have been working collaboratively for
eight years to develop this potential carbon capture solution that
demonstrates stability in the presence of water vapor, without
oxidation, allowing carbon dioxide to be captured from various
sources, under a number of conditions.
Additional research and development will be needed to progress
this technology to a larger scale pilot and ultimately to
industrial scale.
The research successfully demonstrated that these hybrid porous
metal-organic materials are highly selective and could capture more
than 90 percent of the CO2 emitted from industrial sources. The
materials have much greater capacity for capturing carbon dioxide
and can be regenerated for repeated use by using low-temperature
steam, requiring less energy for the overall carbon capture
process.
“This exciting advance for carbon capture technology is an
outstanding example of how scientists with diverse expertise from
universities, national labs, and industry can come together to
solve fundamental research challenges,” said Jeffrey Long,
professor of chemistry and chemical and biomolecular engineering at
University of California, Berkeley and faculty senior scientist at
Lawrence Berkeley National Laboratory. “We are grateful to have had
such long-term research support from ExxonMobil, without which this
discovery would not have been possible. I hope this success will
serve to encourage further partnerships between industry and
academic research labs.”
ExxonMobil is the world leader in carbon capture, capturing more
carbon dioxide than any other company since 1970 and working on a
portfolio of carbon capture technologies in collaboration with
others. Since 2000, ExxonMobil has invested approximately $10
billion in projects to research, develop and deploy lower-emission
energy solutions. The company continues to expand collaborative
efforts with more than 80 universities, five energy centers and
multiple private sector partners around the world to explore
next-generation energy technologies.
The researchers on the technology as written in Science include
Simon Weston and Joseph Falkowski from ExxonMobil; Eugene Kim,
Henry Jiang, Alexander Forse, Jeffrey Martell, Phillip Milner from
the University of California, Berkeley; and Rebecca Siegelman,
Jung-Hoon Lee, Jeffrey Neaton, Jeffrey Reimer, Jeffrey Long from
the University of California, Berkeley and Lawrence Berkeley
National Laboratory.
