Energy Storage Ventures LLC (ESV) develops, constructs, and operates hydrocarbon storage facilities throughout North America. ESV’s primary focus is on a natural gas liquids (NGL) storage facility in the Utica/Marcellus region of the United States. ESV is currently the parent company of two wholly-owned subsidiaries:

Powhatan Salt Company

is focused on activities and infrastructure related to cavern solution mining in the Salina salt formation in the Ohio River valley.

Mountaineer NGL Storage LLC

is focused on activities and infrastructure related to NGL storage and transport as caverns come online after the solution mining phase.

The Mountaineer NGL Storage project recently acquired a 200-acre site in Monroe County, Ohio and has received strong support from the local community and business community throughout the Ohio River basin. The project is considered a critical component for industrial development throughout the Tristate Marcellus/Utica production region, and will be particularly important to the two proposed ethane cracker projects in Beaver County, Pennsylvania, and Belmont County, Ohio, and associated regional downstream industries involved with ethylene and polypropylene production.
