Techno-economic evaluation for development of onshore carbon dioxide pipeline networks

The southern part of Iran has many CO2 emission sources and considerable potential for storage and utilization demand of CO2 such as oil and gas wells. Based on the importance of CO2 pipeline transport in CCS projects, this study was conducted to develop a budget-type techno-economic model for CO2 transmission through pipelines on the southern coasts of Iran. Although the design of a pipeline project with detailed economic investigations has a lower error, it needs spending a lot of time and cost. Therefore, it is necessary to create a budget-type techno-economic model that includes key technical and economic specifications of CO2 transmission pipelines for Iran like similar studies for other countries. In the present study, first, the requirements and the process of construction of a pipeline were described. Then, different economic budget-type models were developed based on the results of different technical models and the investment costs of the pipelines, booster stations, etc. It is worth mentioning that the developed budget-type techno-economic models have uncertainties due to various technical and economic parameters involved in the modeling. Therefore, a stochastic analysis was performed based on the input parameters of the model. For the case study, the pipeline diameter, the investment cost for the 110-km pipeline, and the levelized cost were calculated to be 0.273 m, 18.37 million €, and 1.55 €/ton, respectively which can be for the basic design of CO2 pipelines.
