[HSC04-P04] Installation of basic calculation module to the CCS cost estimation tool under development
Keywords:Thermal power plant, Onshore pipeline, Ship transportation, Storage, User interface, DBMS
BACKGROUND
It will take a long time before fossil fuels can be fully converted to renewable and other energy sources, so CCS is now considered the most viable option to achieve the goals of the Paris Agreement and the 2050 carbon neutrality goal. The decision to implement CCS, and how to do it, is left up to the business organization, but taking a long-term perspective and choosing the most economically favorable option is critical to the success of long-term effort.
In order to calculate the costs for CCS, information on the equipment configuration and components appropriate for the type of CCS project is necessary, such as construction, equipment, operation, and monitoring costs of the basic plant for each process.
Based on this information, calculations are made taking into account the annual capture volume, transport distance and method, injection method, operating years, as well as discount rate, exchange rate, legal useful life, external power supply costs, and other factors. If there are multiple possible cases, it is necessary to perform calculations for each case and compare them.
A person who is familiar with the above calculations and has engineering knowledge of CCS may be able to perform the calculations while referring to the necessary tables. However, calculating a large number of cases and combining these results would be a hard work even for experts.
In view of the above, Geological Carbon Dioxide Storage Technology Research Association is developing a cost estimation tool to enable non-specialists to perform calculations for various cases of CCS. In addition to standard CCS cost estimation, the tool is being developed to meet the expectations of specialists by enhancing the functions of the system so that it can handle hub-and-cluster and sensitivity analysis.
Modules that have been installed
The tool consists of three parts: (1) user interface, (2) database, and (3) calculation engine, and we have finished framing the entire tool and installing the basic modules in the calculation engine.
The calculation engine is the most important part of CCS cost estimation, and it contains coded information on equipment configuration, each cost, various coefficients, and calculation procedures for each process (some information is stored in the database). This allows users to obtain appropriate estimation results without detailed knowledge of CCS.
The calculation engine has several modules for each process of capture, transportation, and storage. Currently includes modules for coal-fired power plants and LNG-fired power plants for capture, onshore pipelines and ships for transportation, and a pattern of injection from land to sub-seabed by inclined wells for storage. In addition to the calculations for each process, there is a system that controls their execution in the calculation engine.
In this presentation, examples of calculations that can be performed with the current tool configuration will be presented.
Future Development Plan
Since the overall frame of the tool has been completed, we will build various modules for each process of the calculation engine from now on. We will proceed with development starting with high priority modules, but the basic requirement is that the data must be publicly available or accessible. In addition, we plan to enhance the functionality of the system that controls each module in the calculation engine. Ultimately, a cost estimation tool that can be used in various cases will be completed.
