Direct Air Capture Scaling Analysis

Environment and Climate Change Canada (ECCC) requires a scaling analysis of the practical potential of the deployment and use of Direct Air Capture systems in Canada. The contractor will perform each task listed below. • Subtask 1 A techno economic engineering analysis of the top two most likely DAC technology candidates to be potentially deployed in Canada (within the 2030 and 2050 time frame), providing the following information: o Detailed technical description of the system. o Process flow diagrams (actual or estimated). o Mass and energy balances for the system (actual or estimated). o CAPEX and OPEX estimates. o TRL levels and development description, including risk analysis, of remaining work to get system to the highest level TRL (commercial operation with experience and high reliability). o Any special operating requirements. o CO2 removal performance and annual removal rates (and the conditions to which the quoted performance and rates apply), external energy input (heat, power, and rates thereof) and chemical/consumable inputs for one unit’s operation annually. • Subtask 2 Scalability analysis: o Gross estimates of number and location of units to remove various levels of CO2 from the ambient air in Canada o Estimate total required energy inputs and identify practical, GHG emissions-free and additional sources for that energy, including through the use of power purchase agreements (PPAs) to supply emissions-free energy to DAC projects. o Estimate geographic footprints of source energy from different types, and potential locations. (for example, what is the geographic footprint for the power source, it its solely wind powered, PV solar powered, nuclear powered, etc). o Discuss other manufacturing, logistical, economic, legal, and political factors for increasing scale of use.
