Geological carbon storage is widely recognised to be a key asset in tackling anthropogenic emissions and climate change to reach a sustainable 'net zero'. Geological heterogeneities can play an important role in the storage units because they control the presence of barrier and baffles. Their impact can either be positive (e.g., decrease the rate at which the CO 2 exceeds the limits of the storage site), or negative (e.g., reduce the effective reservoir volume causing CO 2 loss). Accordingly, understanding the geological lateral and vertical variability of a CO 2 reservoir is a critical aspect when assessing the risk and viability of CCS projects.

地质碳储存被广泛认为是应对人为排放和气候变化以实现可持续“净零”的关键资产。地质不均匀性可以在存储单元中发挥重要作用，因为它们控制了屏障和挡板的存在。它们的影响可以是积极的（例如，降低CO2超过储存地点限制的速率），或负的（例如，减少有效储层体积，造成CO2损失）。因此，在评估CCS项目的风险和可行性时，了解CO2储层的地质横向和纵向变异性是一个关键方面。
