Ideal locations for large-scale CO₂ capture include gas processing plants, fertilizer manufacturing facilities, thermal power plants and other sites that produce large amounts of CO₂, often in excess of one million tonnes of CO₂ equivalent (MtCO₂e) annually (IEA, 2004). These industrial facilities are often located near others, thus increasing the amount of available CO₂ for capture within the general vicinity.

The most suitable sites for cost-effective long-term emissions storage in Canada include geological formations such as active or depleted oil, gas and coalbed methane reservoirs, deep saline aquifers and salt caverns.

CO₂ Storage Options:

CO₂ storage can be the end result when using it as a by-product in energy production operations and/or disposal operations, such as: 

• Enhanced Oil Recovery
• Enhanced Gas Recovery
• Enhanced Coalbed Methane Recovery
• Acid Gas Injection
• Gas over Bitumen
• Temporary Storage
• Depleted Oil and Gas Pools
• Deep Saline Aquifers
