Monitoring and Verification (M&V) was reviewed in this journal in 2015 as part of the Special Issue to mark the tenth anniversary of the IPCC report on CCS. This article provides an update, focusing on identifying areas where there has been technical progress. Activity in CCS has continued since 2015, but the shift towards commercial utilization has altered the context for M&V. Published field experimentation, and verification with monitoring methods, has not progressed as much as was hoped. While much high-quality theoretical work has continued, especially in the area of the design of monitoring systems, an imbalance is apparent. One area where field tests have continued, and progress has been marked, is the rapid development of distributed acoustic sensing and its pairing with permanent seismic sources. Progress here has the potential to make seismic monitoring cheaper and less intrusive. Interesting proposals have been made for monitoring with pressure data, but most have not been tested. Methods of monitoring in the marine ecosystem are rapidly being adapted to the requirements of M&V. These methods are well adapted to the quantification of leakage that is mandated in some jurisdictions. Overall, the need for testing the numerous good ideas in field experiments is very apparent.

为了纪念IPCC关于CCS的报告十周年，《监控与核查》（M＆V）于2015年作为特刊的一部分在此期刊上进行了回顾。本文提供了一个更新，着重于确定技术上已取得进展的领域。自2015年以来，CCS的活动一直在继续，但是向商业利用的转变改变了M＆V的环境。公开的现场试验和监测方法的验证进展不如预期。尽管继续进行许多高质量的理论工作，尤其是在监视系统设计领域，但这种不平衡是显而易见的。分布式声学传感技术的快速发展及其与永久地震源的配对是现场测试持续进行并取得显着进展的一个领域。此处的进展有可能使地震监测更便宜且更具侵入性。已经提出了一些有趣的建议来监视压力数据，但是大多数尚未经过测试。海洋生态系统中的监测方法正在迅速适应M＆V的要求。这些方法非常适合某些司法管辖区要求的定量泄漏。总体而言，在现场实验中测试众多好主意的需求非常明显。
