Air Products on Tuesday announced it would cancel its $4.5 billion Louisiana Clean Energy Complex, which faced opposition from environmental groups and communities near the proposed injection site.

The Pennsylvania company had in 2021 first proposed building a new industrial plant in Ascension Parish that would make hydrogen and ammonia from natural gas, according to New Orleans Times-Picayune. Its plans involved piping carbon dioxide to Lake Maurepas, a brackish estuary west of New Orleans used for hunting, fishing, and boating.

Air Products had intended for the project to quality for federal carbon storage tax credits expanded by the Biden Administration. That proposal drew opposition both from left-leaning environmental groups skeptical of the project’s alleged climate benefits, as well as conservatives concerned about the use of taxpayer funds, private property rights, and impacts to Lake Maurepas.
