Compressed Air Energy Storage in Salt Caverns
EF 2018-19
Résumé
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
