Abstract

The aim of this study was to identify an optimal CCS transport infrastructure for Polish energy sector in regards of selected European Commission Energy Roadmap 2050 scenario. The work covers identification of the offshore storage site location, CO 2 pipeline network design and sizing for deployment at a national scale along with CAPEX analysis. It was conducted for the worst-case scenario, wherein the power plants operate under full-load conditions. The input data for the evaluation of CO 2 flow rates (flue gas composition) were taken from the selected cogeneration plant with the maximum electric capacity of 620 MW and the results were extrapolated from these data given the power outputs of the remaining units. A graph search algorithm was employed to estimate pipeline infrastructure costs to transport 95 MT of CO 2 annually, which amount to about 612.6 M€. Additional pipeline infrastructure costs will have to be incurred after 9 years of operation of the system due to limited storage site capacity. The results show that CAPEX estimates for CO 2 pipeline infrastructure cannot be relied on natural gas infrastructure data, since both systems exhibit differences in pipe wall thickness that affects material cost.

Highlights

The long-term warming of the climate system is mainly driven by CO2 emissions, the internationally agreed objective of limiting the increase in global average temperatures to well below 2°C above pre-industrial levels requires significant reductions in CO2 emissions
The main objective of this study is to identify an optimal group selection of power plants, which contribute 32% to national power generation capacity for achieving European Commission 2050 emissions target
CO2 streams for power plants have been calculated based on the analysis carried out for “Siekierki” power plant, located in Warsaw, whose flue gas composition was obtained from plant operator

Summary

Introduction

The long-term warming of the climate system is mainly driven by CO2 emissions, the internationally agreed objective of limiting the increase in global average temperatures to well below 2°C above pre-industrial levels requires significant reductions in CO2 emissions. As the CO2 flow rate that can be handled by a trunkline is increased, the levelized cost of transporting it declines exponentially They conclude that low transportation costs over long distances open up the possibility for developing CCS systems that connect CO2 sources to far away storage sites where storage costs are relatively low. Some key design issues that must be considered for the development of large scale CO2 transportation network are reviewed in the study by Han et al [13]. They conclude that to ensure the safe and cost-effective transportation, the concentrations of impurities in CO2 stream should be restricted in an appropriate range. The comparison to the current natural gas infrastructure capital expenditures is made
