USA: Carbon Capture Exxon Mobil Discovers New Material to Capture 90 % CO2
Exxon Mobil has collaborated with the University of California, Berkeley and Lawrence Berkeley National Laboratory to discover the new material. The innovation is capable of capturing more than 90 % of CO2 emitted from industrial sources.
Texas/USA – Scientists from Exxon Mobil, University of California, Berkeley and Lawrence Berkeley National Laboratory have discovered a new material that could capture more than 90 per cent 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-functionalised 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 recently 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 Exxon Mobil 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 Exxon Mobil is researching to reduce CO2 in the production of energy,” said Swarup.
Exxon Mobil’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 vapour, 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 per cent 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 Exxon Mobil, 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.”
