As renewable resources such wind and solar are increasingly integrated into the power grid, the intermittent**and dispersed nature of these resources is having a significant impact on the reliability and resilience of the grid**system. A storage medium not only can facilitate renewables integration, but can also help address the**balancing of local and regional generation sources, and can reduce the level of base load need. Cost-effective**energy storage on a large scale is necessary to improve overall performance and enhance reliability of the grid.**We propose Compressed Air Energy Storage (CAES) in Salt Caverns in Canada as a promising option to**enable a large share of renewable energy generation into the power grid.**Through the National Research Council Canada, the Canadian government has established the Energy Storage**for Grid Security and Modernization Initiative. The Ontario government, in its Long-Term Energy Plan, is also**committed to address regulatory barriers that limit the ability of energy storage technologies to compete in**Ontario's electricity market. By the end of 2014, the government will include storage technologies in its**procurement process, starting with 50MW and assessing additional engagement on an ongoing basis.**For successful commercialization of CAES in Canada on a grid-wide basis, we propose salt caverns as the**most suitable geological medium and it is present in bedded form in southwest Ontario and east-central**Alberta. Suitable salt strata for CAES are also present in Nova Scotia, New Brunswick and Saskatchewan. The**domains of this research project include: geoscience and geotechnical analysis of cavern design including the**novel concept of long galleries dissolved in salt, thermo-mechanical assessment of turbine operation, design**and cycling, including heat scavenging, and grid integration modeling to assess scale effects of storage facilities**and locations on variable generation (intermittent input in terms of time and magnitude) and capability for

随着风能和太阳能等可再生资源越来越多地融入电网，这些资源的间歇性和分散性对电网系统的可靠性和弹性产生了重大影响。存储介质不仅可以促进可再生能源的整合，还可以帮助解决本地和区域发电源的平衡问题，并可以降低基本负荷需求水平。大规模经济高效的储能对于提高电网的整体性能和可靠性是必要的。我们建议在加拿大盐洞的压缩空气储能（CAES）作为一个有前途的选择，以 ** 使大部分可再生能源发电进入电网。通过加拿大国家研究理事会，加拿大政府已经建立了电网安全和现代化倡议的能源存储 **。安大略政府在其长期能源计划中也 ** 致力于解决限制储能技术在 ** 安大略电力市场竞争能力的监管障碍。到2014年底，政府将把储能技术纳入其 ** 采购流程，从50兆瓦开始，并持续评估额外的参与。为了在加拿大的网格范围内成功商业化CAES，我们建议盐穴作为 ** 最合适的地质介质，它以层状形式存在于安大略西南部和阿尔伯塔中东部 **。新斯科舍省、新玩法和萨斯喀彻温省也存在适合CAES的盐层。该研究项目的 ** 领域包括：洞穴设计的地球科学和岩土工程分析，包括溶解在盐中的长廊道的 ** 新概念，涡轮机运行的热机械评估，设计 ** 和循环，包括热清除，以及网格集成建模，以评估存储设施 ** 和位置对变量生成（时间和幅度方面的间歇性输入）的规模效应和容量，
