The LRC technology provides an alternative to salt for many regions in the United States, including the Northeast. The gas storage chamber is constructed by first excavating a vertical cylinder in the relatively shallow subsurface. A steel liner is then placed in the excavated cylinder while a special concrete structure is installed between the liner and the excavated rock surface. The LRC concept has been developed in Scandinavia. A field experimental and demonstration site in Sweden was utilized to help develop the concept. Currently, a demonstration facility is being constructed in southern Sweden. The DOE-sponsored LRC project addressed the current state-of-the-art in the LRC concept, market data for conventional alternative storage in the Northeast, identification and selection of two generic geologic sites, conceptual design for the LRC, cost estimate, economic comparison of LRC to alternatives, and environmental impact and permitting issues.
