RITE and OYO Corporation investigated “Design of CO2 geologic storage system and evaluation of storage potential” for feasibility study on “Innovative Zero-emission Coal Gasification Power Generation”. Conclusive remarks of 2010 works are summarized as follows:
1. After surveying information on reservoirs in Japan and conceptual design results of CO2 storage facilities, the reservoir database, the cost database and the economic evaluation tool of CO2 storage were updated.
2. In the site C, the existing seismic reflection data along 11 lines were provided by the operator, of which the data from 3 lines, located near the assumed injection point, were processed.
In the site D, where deep saline aquifers are assessed to have a large potential storage capacity for CO2, the existing data were rearranged in order to build a geological model.
 Geological information on the sites C and D were arranged and a GIS database was constructed for these sites.
3. A three-dimensional geological model for the site C was built, and the rock properties of the formations including the targeted reservoirs were reevaluated.
A three-dimensional geological model for the site D was built, and the formation characteristics such as the continuity and rock properties of the targeted reservoirs and seals were reevaluated.
Reservoir simulations of CO2 injectoins at both demonstration- and commercial-levels were conducted for the sites A, B and C to understand the CO2 storage potential, CO2 saturation ditributions, spread of the CO2 plumes, etc
Based on the results of the numerical simulations, the CO2 injection plans including injection well emplacement, injection rate and number of injection wells for the sites A, B and C were reevaluated.
4. Based on the results of the conceptual designs (injection rates, number of injection wells, injection intervals, etc.) for three geological storage candidate sites, an reevalidation of the conceptual designs for the storage facilities, in the sites was made and an evaluation of conceptual designs of storage facilities at those three sites also were made.
In addition, workflows for pre-operational investigation, monitoring, and well abandonment were examined, respectively
5. A total cost of CO2 storage facilities in three sites were estimated using the results of the revalidation of “the conceptual designs of storage facilities” and the cost of the pre-operational investigation, monitoring, well abandonment, and injection operations.
The results of a cost comparison as a part of an economic evaluation of a CO2 geological storage system show that the OPEX (injection operations and monitoring) per well is higher than the CAPEX (pre-operational investigation, site construction, and well abandonment), of which the monitoring cost occupies a relatively large part of the total storage cost.
6. The trend of CCS policy and recent development of zero-emission coal-fired power generation in EU, the US and Australia that was reported in an international conference was very informative, and the latest trend was understood through the hearing investigation to the organization relative to CCS in Germany, the UK, the US, and Australia.
