在地质储层中捕获和储存CO2可能是减少全球人为CO2排放战略的一部分。需要深入了解与地下CO2储存相关的风险，以确保它可以作为安全有效的温室气体减排选择。本文旨在概述目前（差距）的知识与地下CO2储存和研究领域，需要解决，以增加我们对这些风险的理解。了解地面装置故障造成的风险，并通过风险缓解技术和安全措施将其降至最低。地下CO2储存造成的风险（CO2和CH 4泄漏、地震活动、地面运动和盐水置换）还不太清楚。主要研发目标是确定控制通过/沿着威尔斯、断层和裂缝渗漏的过程，以评估渗漏率并评估对（海洋）生态系统的影响。虽然目前正在开展的研究与发展活动正在研究这些问题，但预计还需要进一步的示范项目和实验工作，以便为更彻底的风险评估提供数据。
CO2 capture and storage (CCS) in geological reservoirs may be part of a strategy to reduce global anthropogenic CO2 emissions. Insight in the risks associated with underground CO2 storage is needed to ensure that it can be applied as safe and effective greenhouse mitigation option. This paper aims to give an overview of the current (gaps in) knowledge of risks associated with underground CO2 storage and research areas that need to be addressed to increase our understanding in those risks. Risks caused by a failure in surface installations are understood and can be minimised by risk abatement technologies and safety measures. The risks caused by underground CO2 storage (CO2 and CH4 leakage, seismicity, ground movement and brine displacement) are less well understood. Main R&D objective is to determine the processes controlling leakage through/along wells, faults and fractures to assess leakage rates and to assess the effects on (marine) ecosystems. Although R&D activities currently being undertaken are working on these issues, it is expected that further demonstration projects and experimental work is needed to provide data for more thorough risk assessment.
