This paper provides a worldwide comparison of CCUS tariffs, analyzing how geology, regulation, and infrastructure shape costs. Total costs range from €20 to €140/tCO2, with T&S tariffs typically €5-€45/tCO2. Capture costs vary greatly by CO2 stream purity. The study offers standardized benchmarks for project feasibility, highlighting that T&S tariffs are a decisive factor once capture costs are fixed.

📄 Abstract（原文）
As Carbon Capture, Utilization, and Storage (CCUS) deployment expands globally, Carbon dioxide (CO2) transport and storage tariffs differ widely due to variations in geology, regulatory frameworks, market maturity, infrastructure availability, and risk allocation models. These factors collectively shape project economics and influence investment decisions across regions. This paper presents a worldwide comparison of CO2 Capture, Transport, and Storage tariffs, analyzing how these diverse cost drivers affect pricing structures and ultimately determine the feasibility and competitiveness of CCUS projects in different global markets. This study applies a comparative analytical approach using publicly available worldwide CO2 transport and storage tariff data sourced from regulatory filings, national frameworks, project disclosures, and industry reports. Tariffs are reviewed alongside key cost-shaping factors, including geology, infrastructure maturity, regulatory design, market structure, and risk allocation. Each region is assessed to identify patterns, variations, and the underlying drivers behind cost differences. The analysis highlights how diverse tariff structures globally influence CCUS project feasibility, investment decisions, and overall value-chain competitiveness. In line with common industry practice, transport and storage costs are collectively referred to as "storage tariffs" when disaggregated data are unavailable. The analysis reveals substantial global variability in CCUS tariffs, with total costs (capture + transport + storage) ranging from approximately €20 to €140 per tonne of CO2, and a weighted average near €55/tCO2 under many "mature" conditions. Focusing on transport and storage (T&S) costs effectively the "storage tariff" typical ranges are €5 to €45/tCO2 for onshore pipeline transport and injection, depending on distance, CO2 volume, reservoir geology, and monitoring requirements. In favorable geological regions, such as depleted oil and gas fields, T&S costs are generally €15- €37/tCO2, while more challenging saline-aquifer storage sites often reach €35- €45/tCO2. Capture costs vary sharply with CO2 stream characteristics: high-purity streams from gas processing or natural gas operations often incur €25-€35/tCO2, whereas dilute streams from cement, steel, or power plants can range €70-€90/tCO2 or higher. Integrated industrial hubs, where multiple emitters share pipelines and storage facilities, significantly reduce per-tonne costs due to economies of scale and shared infrastructure. Overall, regions with low storage tariffs combined with favorable capture sources can achieve economically competitive CCUS. However, in many areas, total costs remain high, indicating that policy support, carbon pricing, or financial incentives are crucial to enable large-scale deployment globally. This paper offers a first‑of‑its‑kind structured, side‑by‑side comparison of global CCUS tariffs using a standardized economic framework with real world ranges, enabling engineers and project planners to benchmark cost competitiveness across geographies, storage types, and CO2 source characteristics. It fills a practical gap in literature by translating cost data into actionable tariff ranges for project feasibility assessments and design decisions. While prior studies focus on project-specific costs or modeled estimates, few provide a standardized, cross-regional tariff benchmark grounded in operational projects. The results demonstrate that transport and storage tariffs, often treated as secondary, are a decisive feasibility factor once capture costs are fixed.
