可再生能源越来越多地纳入电网，预计将大大有助于实现欧洲联盟的能源和温室气体减排目标。然而，这也给电网带来了新的挑战。大规模储能可以为更好地整合可再生能源、平衡供需、提高能源安全、加强电网管理以及实现低碳经济提供手段。确保大规模储能的一种方法是利用地下水库的储能能力，因为地质构造具有储存大量流体而对环境和社会影响最小的潜力。地下储能技术有多种可行的选择，地下水库也有多种可供选择，本文介绍的可再生能源集成地下储能技术有：压缩空气储能（CAES）、地下抽水蓄能（UPHS）、地下热能储能（UTES）、地下储能系统（UES）。地下储气库（UGS）和地下储氢库（UHS），两者都连接到电力到天然气（P2G）系统。对于这些不同类型的地下储能技术，有几种合适的地质储层，即：枯竭的碳氢化合物储层，多孔含水层，盐层，主岩中的工程岩石洞穴和废弃矿井。具体的场地筛选标准适用于每种储层类型和技术，确定储层本身的可行性，以及该场地的技术。本文提出了一个审查的标准，适用于确定合适的技术油藏夫妇。
The increasing integration of renewable energies in the electricity grid is expected to contribute considerably towards the European Union goals of energy and GHG emissions reduction. However, it also brings new challenges for the grid. Large-scale energy storage can provide means for a better integration of renewable energy sources, balancing supply and demand, increasing energy security, enhancing a better management of the grid and also allowing convergence towards a low carbon economy.One way to ensure large-scale energy storage is to use the storage capacity in underground reservoirs, since geological formations have the potential to store large volumes of fluids with minimal impact to environment and society. There are several technologies which can be viable options for underground energy storage, as well as several types of underground reservoirs can be considered.The underground energy storage technologies for renewable energy integration addressed in this article are: Compressed Air Energy Storage (CAES); Underground Pumped Hydro Storage (UPHS); Underground Thermal Energy Storage (UTES); Underground Gas Storage (UGS) and Underground Hydrogen Storage (UHS), both connected to Power-to-gas (P2G) systems. For these different types of underground energy storage technologies there are several suitable geological reservoirs, namely: depleted hydrocarbon reservoirs, porous aquifers, salt formations, engineered rock caverns in host rocks and abandoned mines.Specific site screening criteria are applicable to each of these reservoir types and technologies, determining the viability of the reservoir itself, and of the technology for that site. This paper presents a review of the criteria applied to identify suitable technology-reservoir couples.
