On July 12, 2024, Air Products Blue Energy applied for permission from Louisiana Department of Energy and Natural Resources to inject carbon dioxide from its proposed hydrogen and ammonia facility in Ascension Parish into five carbon dioxide storage wells under Lake Maurepas in St. John the Baptist Parish, Louisiana.

The wells would store an estimated 5 million metric tons from the proposed hydrogen and ammonia plant each year. The proposal has drawn opposition from environmentalists concerned about carbon dioxide leaks and crabbers who say the well platforms and seismic testing needed for the project affect their catch.
