For licences related to compressed air energy storage projects in porous rock Review sections 2 and 2.1 of Ontario Regulation 245/97, and the definitions of ''porous rock reservoir'' and ''pinnacle structure'' in the regulation
6 FAQs about [Oil well air energy storage project]
Can depleted oil & gas wells be used for energy storage?
The idea is to use depleted oil and gas wells as a reservoir for the storage of compressed natural gas. As needed, the gas can be released to spin a turbine and generate electricity. The reservoir is recharged using excess electricity from the grid and the cycle repeats, providing a potential solution for the growing demand for energy storage.
What is energy storage & why is it important?
Energy storage (ES) plays a key role in the energy transition to low-carbon economies due to the rising use of intermittent renewable energy in electrical grids. Among the different ES technologies, compressed air energy storage (CAES) can store tens to hundreds of MW of power capacity for long-term applications and utility-scale.
Could old oil and gas wells be used for storage?
David Young, a senior scientist at NREL whose expertise lies with solar technology, had a “eureka” moment in coming up with the notion to use old oil and gas well sites for storage. “I was taking a shower and I dreamed up the idea,” Young said.
Could compressed air be injected into old wells?
Illustration by Al Hicks, NREL TheNREL researchers initially considered injecting compressed air into the old wells. Augustine took that idea through the Department of Energy’s Energy I-Corps program in 2016. The program helps researchers determine the potential market for their technology.
Can compressed air be used as energy storage?
If you use CO 2 that could also be part of a carbon capture cycle.”Using compressed air as energy storage requires additional steps, including cooling the air after the compression stage and preheating it before releasing it. Projects using compressed air also can take years to build and cost hundreds of millions of dollars.
Could depleted oil and gas wells be used as a reservoir?
