10 Conclusions and lessons learned
The technical and financial outcomes of the Table 10-1.for the Getica CCS Demo Project are summarised in
The key outcomes of the Feasibility Study are:
- selection of the Chilled Ammonia PCC technology for CO2 capture;
- optimisation of the thermal integration of the CCP into the power plant with resulting performance profile;
- preliminary design for the 40 km, 350 mm CO2 pipeline to either of two storage options;
- a shortlist of two possible onshore storage sites (Zone 5 or 1) and the development of the Basis of Design for the Appraisal wells construction and evaluation;
- a cost estimate for investment and operation of the Getica CCS Demo Project;
- identification of sources of direct funding (grants);
- assessment of preliminary environmental impacts of the CCS Project; and
- identification of the risks to the CCS project during the FEED, EPC, operation and post-operation phases.
The key lesson learned during the Feasibility Study resulted from the storage assessment process. Namely, there was a high degree of effort needed to acquire the existing geological data for the potential storage area. This is due to the Getica project targeting deepformations in an area where several oil and gas companies have conducted prospecting campaigns in the past.
Further, the data collection process itself (data in various formats from different companies) is time consuming. Depending on the source of information, procedures and protocols had to be followed, such as engaging the oil and gas national authority, consolidation of data in a satisfactory database, and the digitalisation of the data in a common usable format.
Based on ISPE’s experience, the acquisition of initial data (2D/3D seismic, well data) for future CCS projects globally can be grouped into the following categories:
- no existing geological prospecting data;
- geological data available from a single source; and
- geological data available from multiple sources.
The advantages and disadvantages for each of these categories are presented in Appendix D. The second scenario is considered the optimal scenario (geological data is available from a single source and that source is the developer of the CCS project). It is the scenario that provides an acceptable balance between cost, time and risks during the assessment and characterisation phases.
The successful implementation of the Getica CCS Demo Project will contribute to the continued operation of power plants running on local lignite, contributing to the security of supply, not only in Romania, but also in Central – Eastern Europe.
The first CCS project increates an opportunity for future applications of the technology to other power producers in the region (over 4,000 MW) on local lignite and other major industrial CO2 emitters (metallurgical, refinery, chemical, cement, etc.).
The appraisal activities to be performed within the Getica project onshore storage system will be valuable for future CO2 storage activities in the area. Based on the knowledge generated by Getica, there may be potential for future EHR developments in the region.
There is also a high potential to develop the CCS transport and storage infrastructure for the industrial CO2 emitters in the region, at country and cross-border levels. The value of the data to be acquired during the storage characterisation extends beyond the Getica project; as such data could be used for the potential further development of a storage hub in the area.
As a result of these factors, future CCS projects in the region will be able to leverage off lessons learned from the Getica project to help overcome barriers to CCS deployment.
