Carbon Capture, Utilization, and Storage Technology Overview
Carbon capture technology overview
Carbon capture technology refers to various methods of capturing carbon dioxide (CO2) from flue gases in industrial processes or directly from the atmosphere to reduce its emission into the atmosphere. Major carbon capture technologies include chemical absorption, physical adsorption, and membrane separation. Chemical absorption is one of the most commonly used techniques, which involves dissolving CO2 in a solvent and then separating and regenerating it for capture. Physical adsorption utilizes adsorbents to capture CO2, which is later released from the adsorbent by increasing temperature or reducing pressure. Membrane separation employs selectively permeable membrane materials to separate CO2 from other gases.
Carbon storage technology overview
Carbon storage technology involves the permanent storage of captured CO2 underground or in the oceans to prevent its release into the atmosphere. Common carbon storage methods include geological storage and ocean storage. Geological storage involves injecting CO2 into underground rock formations such as saline formations, coal seams, and depleted oil and gas fields. During the geological storage process, CO2 is injected into the rock formations and sealed off by impermeable layers to ensure safe storage. Ocean storage, on the other hand, involves injecting CO2 into deep ocean waters or sub-seafloor sediments, utilizing the ocean’s capacity for absorption and dilution to store CO2.
The combination of carbon capture, utilization, and storage technologies forms a complete CCUS technology chain. Carbon capture technology is responsible for capturing CO2 from the source, while carbon storage technology ensures the safe storage of captured CO2, preventing its release back into the atmosphere. This technology finds wide-ranging applications in power plants, industrial production, oil and gas extraction, and other sectors, offering the potential for significant reduction in CO2 emissions and contributing to carbon neutrality goals.
It should be noted that the selection of carbon capture, utilization, and storage technology pathways depends on specific circumstances and conditions. Different industries and processes may be suitable for different technology pathways. Therefore, conducting cost analysis is an important means of assessing the feasibility and economic viability of technology pathways, aiding in identifying the optimal technology combinations and implementation strategies.

Cost Analysis Methods
Cost elements
When conducting cost analysis of carbon capture, utilization,
and storage technology pathways, several cost elements need
to be considered. These cost elements may include, but are not
limited to, the following aspects:
Equipment cost: Includes the procurement and installation
costs of carbon capture equipment, transportation equipment,
storage equipment, etc.
Operation and maintenance cost: Includes energy
consumption, labor for maintenance and operation, etc.
CO2 capture efficiency and energy consumption: Considers the
energy consumption and efficiency during the capture process,
including the cost and energy consumption of chemical solvents
or adsorbents for regeneration.
Transportation cost: The cost of transporting captured CO2 to
the storage location, including pipeline or shipping transportation
costs, etc.
Geological storage cost: Includes costs related to geological
exploration, seal formation construction, monitoring, etc.
Ocean storage cost: Includes costs related to CO2 injection and
monitoring, assessment of marine ecological impacts, etc.
Cost assessment methods
Various assessment methods can be employed for cost
evaluation of carbon capture, utilization, and storage technology
pathways. Here are some common methods:
Benchmarking: Comparing new technologies with existing
ones to assess cost differences.
Life Cycle Cost Analysis: Considering the entire lifecycle of
the technology pathway, including equipment procurement,
operation, maintenance, and disposal, to comprehensively
evaluate cost effectiveness.
Sensitivity Analysis: Assessing the impact of key parameters
on costs through variations and sensitivity tests.
Techno-economic Assessment: Considering indicators such as
return on investment, discount rate, internal rate of return, etc., to
evaluate the economic feasibility.
Data collection and analysis
Cost analysis requires collecting relevant data, including technical data and cost data. Technical data involve performance parameters, energy consumption indicators, and efficiency of carbon capture, utilization, and storage technologies. Cost data include equipment costs, operation and maintenance costs, energy costs, and related transportation and storage costs. These data can be obtained through literature research, industrial case studies, expert consultations, and field investigations.
After data collection, the data needs to be analyzed. Statistical analysis methods can be used to organize and summarize the data, calculate averages, standard deviations, correlation coefficients, etc. Additionally, cost analysis models can be constructed to simulate and predict costs for different technology pathways. Through data analysis and simulation experiments, a deeper understanding of cost structures and influencing factors for different technology pathways can be obtained, providing a scientific basis for cost evaluation.

This technology pathway has a higher equipment cost in its cost structure, primarily due to the high procurement and installation costs of carbon capture and related equipment. Operation and maintenance costs are relatively stable, including energy consumption and labor costs for maintenance. CO2 transportation cost is relatively low, depending on the transportation distance and method. Geological storage cost is relatively high, including costs related to geological exploration, seal formation construction, and monitoring. Through the cost analysis of Technology Pathway A, we can evaluate its economic feasibility and sustainability, providing reference for decisionmaking.

For the cost analysis results of Technology Pathway B, we have found the following main discoveries: Equipment cost accounts for 40% of the total cost, operation and maintenance cost accounts for 25% of the total cost, CO2 transportation cost accounts for 15% of the total cost, and ocean storage cost accounts for 20% of the total cost. The equipment cost of this technology pathway is relatively low, mainly due to the adoption of mature and lowcost carbon capture equipment. Operation and maintenance costs are relatively stable, with low energy consumption and moderate labor costs for maintenance. CO2 transportation cost is high, primarily influenced by the transportation distance and the unique characteristics of ocean storage. Ocean storage cost has a relatively high proportion, including CO2 injection and monitoring costs, as well as the assessment of impacts on marine ecological environments. By considering the cost analysis results of Technology Pathway B comprehensively, we can evaluate its feasibility in terms of economics and the environment.

Regarding the cost analysis results for Technology Pathway C, we have observed the following main scenarios: Equipment cost accounts for 60% of the total cost, operation and maintenance cost accounts for 20% of the total cost, CO2 transportation cost accounts for 10% of the total cost, and geological storage cost accounts for 10% of the total cost. The equipment cost of this technology pathway is relatively high, primarily due to the adoption of novel and efficient carbon capture equipment, which entails higher research and manufacturing costs. Operation and maintenance costs are moderate, with relatively low energy consumption and reasonable labor costs for maintenance. CO2 transportation cost is low, mainly influenced by the transportation distance and method. Geological storage cost has a relatively low proportion, but the costs related to geological exploration, seal formation construction, and monitoring still need to be considered. By considering the cost analysis results of Technology Pathway C comprehensively, we can evaluate its economic benefits and feasibility.

Discussion and Explanation of Cost Analysis Results
Analysis of cost differences among different technology pathways
Through the cost analysis of different technology pathways, we can compare the cost differences among them. Technology Pathway A has higher equipment costs, primarily due to the adoption of advanced and efficient carbon capture equipment. Technology Pathway B has relatively lower equipment costs because it utilizes mature and cost-effective carbon capture equipment. On the other hand, Technology Pathway C has relatively higher equipment costs, which may be attributed to the adoption of novel and efficient carbon capture equipment. However, this could also imply better performance and higher capture efficiency. Additionally, there are differences among the technology pathways in terms of operation and maintenance costs, CO2 transportation costs, and storage costs. By comparing the cost differences among different technology pathways, we can select the most suitable pathway for specific needs and conditions.
Sensitivity analysis of cost factors
During cost analysis, we need to consider the sensitivity of different cost factors to the total cost. Through sensitivity analysis, we can assess the impact of different factors on costs and identify key cost drivers. For example, equipment costs and energy costs are typically significant cost drivers and have a substantial influence on the total cost. For Technology Pathway A, equipment costs have a higher proportion, so any changes in equipment costs will have a significant impact on the total cost. For Technology Pathway B, CO2 transportation costs are higher, thus changes in transportation distances will significantly affect the total cost. Conducting sensitivity analysis of cost factors helps us understand the degree of influence different factors have on costs and enables the formulation of corresponding strategies and measures.
Consideration of feasibility and sustainability
In addition to economic feasibility, we also need to consider the feasibility and sustainability of carbon capture, utilization, and storage technology pathways. Feasibility encompasses technical feasibility and operational feasibility. Technical feasibility considers factors such as technology availability, reliability, and maturity to ensure that the technology can operate effectively in practical applications. Operational feasibility involves the operability and management feasibility of the technology pathway, including operational management, safety management, and monitoring management, among others. At the same time, sustainability considers the impact of the technology pathway on the environment and society, including the sustainability aspects of energy resource utilization, carbon emission reduction, and impacts on geological or marine environments. By comprehensively considering feasibility and sustainability factors, we can assess the feasibility and long-term sustainability of the technology pathways more comprehensively.
Through the discussion and explanation of the cost analysis results, we can gain in-depth understanding of the economics, cost differences, sensitivity, and feasibility of different technology pathways, providing crucial reference for decision-making [1-20].
