Current sensors used to detect CO2 at surface sites are either very expensive or they use a lot of energy. And they're not as accurate as they could be. Dr. Harry Ruda of the Centre for Nanotechnology at the University of Toronto and Dr. David Risk, Earth Sciences Department at St. Francis Xavier University, are working on single nanowire transistors that should have unprecedented sensitivity for detecting CO2 emissions. The sensors could provide complete topographic and temporal mapping of carbon emissions, which would help in the design of new protocols for carbon storage and recovery systems as well provide the means for enforcing regulationsall of which will enable markedly reduced emissions. Dr. Risk's role will be in testing and translational work that will help embed the sensors in these real-world application environments.
Project: Development of single-molecule level multi-species nanowire-based sensors for carbon emissions
Project: Accelerating carbon mineralization in mine wastes
Lead Investigator: Greg Dipple, University of British Columbia (UBC)
Co-PIs: Michael Hitch, UBC; Ulrich Mayer, UBC; Gordon Southam, U of Western Ontario; Siobhan Wilson, Monash University (Australia); John Wen, U of Waterloo; Murray Thomson, U of Toronto
CMC Investment: $600,000/3 years
The long-term goal of the carbon mineralization project is to develop methods for accelerating carbon sequestration within mine waste and, through partnership with industry, establish a demonstration project for carbon mineralization.
Many mines produce waste capable of storing CO2 but passive fixation rates from the atmosphere are generally slow (50,000 tonnes CO2 per year or less per mine site). By increasing the level of CO2 in gas streams, the research team can accelerate mineralization in hard rock mine waste
