碳捕集和封存（CCS）是唯一可用于减轻持续使用化石燃料燃烧产生的温室气体排放的工业规模技术。该技术包括捕获煤、石油、天然气和生物质燃烧释放的二氧化碳，压缩二氧化碳，并将其埋在地表以下至少800米的枯竭石油储层和盐水层中。一旦进入地下，二氧化碳必须留在那里。监控存储站点至关重要，需要持续数十年甚至数百年。大多数监测技术需要信号的产生和接收，是间歇性的，并不直接响应地下CO2的存在和数量。我们已经证明，muography可以应用于监测CO2的地质储存网站。监测是被动的，连续的，使用自然发生的宇宙射线μ子，并直接响应探测器和地球表面之间的二氧化碳量。通过覆盖层到存储地点的μ子传输进行了建模，然后建造和测试了一个原型探测器，该探测器可以部署在钻孔内和地球表面深处的恶劣环境中。
Carbon capture and storage (CCS) is the only industrial‐scale technology available to mitigate against the continued use of fossil fuels in terms of emissions of greenhouse gases generated from combustion. The technology involves capturing carbon dioxide as it is liberated from combustion of coal, oil, gas, and biomass, compressing the CO2, and burying it at least 800 m below the Earth's surface in depleted petroleum reservoirs and saline aquifers. Once in the ground, the CO2must stay there. Monitoring storage sites is critical and needs to occur for tens, even hundreds, of years. Most monitoring technologies require signal generation and receipt, are episodic, and are not directly responsive to the presence and quantity of CO2in the subsurface. We have demonstrated that muography can be applied to the monitoring of CO2in geostorage sites. The monitoring is passive, continuous, uses naturally occurring cosmic‐ray muons and is directly responsive to the quantity of CO2between the detectors and the Earth's surface. Muon transport through the overburden to the storage sites was modelled and then built and tested a prototype detector that could be deployed within a borehole and in a hostile ambient environment deep below the Earth's surface.
