Oil well air energy storage project bidding

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.

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.

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.

What is the maximum bidding demand for a heating system?

During heat purchase periods, the maximum bidding demand is 45 MW. And during heat selling periods, the heating capacity bidding range is 0, 30 MWh. The proportion of flexible demands is ρ = 0. 4 for both the EH and general consumers in the heating market.

How much does a natural gas project cost?

Projects using compressed air also can take years to build and cost hundreds of millions of dollars. By taking advantage of existing wells, a pilot site that uses natural gas can be installed for a few million dollars within months, the scientists estimated.
