The hydrogen pipeline would transport hydrogen from the production facility to Air Products' existing pipeline network in Ascension Parish. The natural gas pipeline will begin at a tie-point approximately 5 miles north of Gramercy and will be located in St. John the Baptist and Tangipahoa Parishes. The natural gas pipeline will provide energy for the proposed sequestration facilities in Lake Maurepas.
