Sequestration Capacity Assessment •

Sequestration Capacity Assessment
•  Generally used in the context of regional or national
assessment of the maximum amount of CO
2
that could
be sequestered
–  Evaluated in units of mass of CO
2
(typically Mt or Gt)
–  Does not consider economics
–  Does not consider rate of sequestration
•  Lots of confusion about definitions
–  Risked Capacity (rules out higher risk sites)
–  Dynamic Capacity (also considers rate of sequestration, which is
limited by pressure buildup)
–  Source Sink Matched Capacity (considers where CO
2
sources
are located today)
•  Typically does refer to an assessment of how much CO
2
could be sequestered at one specific site
