For CCUS ITC purposes, CRA considers that “storage” of captured carbon includes monitoring the carbon (but not exploration of the formation)

Regarding the scope of para. (c) of Class 57 (referencing “equipment that is used solely for the storage of captured carbon in a geological formation”) in relation to potentially accessing the carbon capture, utilization and storage (CCUS) investment tax credit, CRA indicated that the monitoring of the captured carbon during the storage phase would appear to be necessary and integral to storage, so that such monitoring activities could be considered part of “storage” for para. (c) purposes. “Storage” also includes the injection of the carbon dioxide.

However, it does not include exploration, including for determining the adequacy of the geological formation for storage.
