On June 14, 2018, CO2 Utilization Roundtable was held in
in Hangzhou. The symposium was co-organized by Columbia
University and Zhejiang University, and the main topic was
about the development of CO2 Utilization. More than 30 famous
experts from all over the world participated in the roundtable.
The symposium began with the issue of ”°Recent advances and
outlook of CO2 capture and conversion technologies in China”±.
And four topics including ”°Direct Air Capture and CO2 Capture”±,
”°Mineralization”±, ”°CO2 to Chemicals and Fuels”±, ”°Policy,
Regulations and Product Certifications”± were deeply explored.
In Topic 1, Professor Tao Wang presented a report entitled
”°Recent Advances and Outlook of CO2 Capture Technologies
in China”±, and Professor Berend Smit of EPFL led the discussion.
Professor Wang discussed the development of various kinds
of carbon capture technologies in China and put forward
the future prospect of China's carbon capture technology.
The participants had a heated discussion, several ideas
were put forward, especially for the direct air capture
and CO2 capture. Alexander of Royal Dutch Shell proposed
CCS and CCUS technology should be assessed roundly. Professor
Alissa Park of Columbia University think simultaneous control
of CO2 and SO2 is a promising technology. Professor Zhongyang
Luo come up with the viewpoint that the capture is more
difficult than utilization.
In topic 2, Sichuan University Dr Siyang Tang gave a report
entitled ”°Development of CO2 mineralization in China”±, and
Prof. Greg Dipple hosted the discussion. Dr Siyang Tang
detailed the development of carbon dioxide mineralization
in China and the great demand of the Chinese government
for energy conservation and emission reduction were discussed.
Based on analysis and discussion of the development of CCUS
technology in Chinese industry, Prof Mengxiang Fang thinks
that CCUS technology has a broad application prospect in
China in the future.
In topic 3, Prof Xinbin Ma of Tianjin University reported
”°Chemical Utilization of Carbon Dioxide”±, and the discussion
was led by Prof Chunshan Song of Pennsylvania state university.
Prof Ma carried out the discussion from the angle of clean
and efficient utilization of coal, and introduced the the
development of CCUS technology in China. Finally, the chemical
synthesis method of CO2 utilization was mainly discussed.
Prof Rui Xiao from Southeast University made an in-depth
analysis of hydrogen source and how to match renewable energy
with CO2 source. Zhang xiangping, a researcher at the Chinese
academy of sciences, and Anne Hauch, a professor at the
Danish university of technology, respectively analyzed the
future of electrochemical technology in carbon dioxide synthesis
and transformation development.
In topic 4, Prof Zheng Li of Tsinghua University reported
on the policy of climate change and CCS, and Dr Colin McCormick
of Valence Strategic, chaired the discussion on the subject.
Prof Li began the issue with the energy structure of China,
pointed out that coal is still the main energy source of
China and the development of CCS technology depends on strong
policy support. Dr. Xiangshan Ma of the global CCS research
institute conducted an in-depth analysis and discussion
on the different international and domestic characteristics
of CCUS technology-related policies.
At the last of symposium, Columbia University Prof David
Sandalow presided over the open discussion, the participants
carried out the summary discussion on difficulties of CCUS
and constructive suggestions on its development.
Columbia University has already hosted two successful CO2
utilization roundtable discussions in 2016 and 2017 and
the outcomes of those meetings have been published as technical
roadmaps. This year, the CO2 utilization roundtable is co-hosted
by Zhejiang University and Columbia University. The chairman
are Prof David Sandalow, Prof Alissa Park, both from Columbia
University, Prof Zhongyang Luo and Prof Tao Wang from Zhejiang
University. The successful holding of the CO2 Utilization
Roundtable has promoted the international CCUS counterparts
to have a broader and deeper understanding of China's contribution
to climate change and will certainly play a positive role
in promoting CCUS development in China.
