The decarbonization of buildings is of paramount importance, and there are many pathways to achieve net-zero. However, electrification is not always practical for all buildings and climates, and it doesn't always reduce CO₂ emissions. Therefore, carbon capture should be considered as part of the solution. This seminar presents three technical approaches to capture building CO₂: from combustion exhaust (boilers, furnaces and power generation); from incoming natural gas supply, producing clean burning hydrogen fuel; and as CO₂ direct air capture from the HVAC systems. All three opportunities will be presented in this comprehensive and cohesive seminar on carbon capture.
