Large-scale carbon dioxide removal (CDR)
Scotiabank Net Zero Research Fund
Thank you to Scotiabank for supporting Canadian and international academic institutions, including the ݮƵ, who have been granted $100,000 to assess marine carbon dioxide reduction approaches, focusing on development, risk assessment and pilot planning for a new technology that can store carbon as bicarbonate in the ocean. The two-year project aims to build an integrated system that can safely change near-surface seawater chemistry to promote natural uptake of CO2 in the ocean as bicarbonate while maintaining viable biospheres in the marine environment.
In the Press
This is very timely given recent discussions at COP26 and the USDOE announcements on Earthshots and CDR
Team
Clockwise from top left: Venkataraman Thangadurai (Chemist), Arthi Gopalakrishnan (Electrochemist), Anna-Maria Hubert (Lawyer), Md Kibria (Engineer),Steve Larter (Geologist), Renzo Correa Silva (Geochemist), Prathap Suba (Electrochemist), Ben Tutolo (Ocean Chemistry)
The team has diverse skills and origins but is committed to “research, develop, and if appropriate, test and deploy socially desirable solutions for large scale carbon dioxide removal”, especially ones that safely amplify natural geochemical processes of carbon dioxide removal from the atmosphere. Such projects are not merely technical in nature but crucially also have to be acceptable to society, so policy and governance and finance are as critical a part of design and construction as science and engineering.
Societal Readiness level (SRL) is perhaps even more important than technical readiness level (TRL).
