US researchers have proposed the use of hydraulically fractured oil and gas wells to store renewable energy via compressed natural gas, with the levelized cost of storage potentially coming in at $70/MWh and $270/MWh. They said wells could also be used to store other renewable gases such as carbon dioxide or hydrogen in the future.Researchers from the US Department of Energy's National Renewable Energy Laboratory (NREL) are proposing the use of horizontal gas and oil wells to store renewable energy via compressed natural gas. The scientists initially considered injecting renewable-powered compressed ...Den vollständigen Artikel lesen ...
