Mitigating impurities is key to effective CCS projects
Transporting CO₂ after its capture is crucial before storage or utilization. Traditionally moved by truck in liquid form for the food and beverage industry, CO₂ is increasingly being transported via pipelines in dense or supercritical phases, especially in the U.S. for Enhanced Oil Recovery (EOR). Despite this, CO₂ pipelines remain a small part of the overall infrastructure. Challenges include impurities from various sources and logistical issues of moving large volumes near populated areas. Accurate measurement and proper reporting are essential for economic viability.
Impurities like moisture can cause corrosion, necessitating advanced measurement technologies. Other impurities, such as hydrogen sulfide and methane, also need monitoring to prevent harmful reactions. Effective CO₂ transport and storage require selecting the right technologies for measuring composition and flow, balancing cost, efficiency and reliability. As carbon capture and storage (CCS) projects grow, addressing these technical and economic challenges is crucial for safe and efficient CO₂ transport and storage.
