ExxonMobil has been named by Clean Hydrogen Works as an additional defendant an in existing anti-trust suit over access to a CO2 pipeline. Clean Hydrogen Works alleges that CO2 enhanced oil recovery firm Denbury, now acquired by ExxonMobil, unlawfully terminated its previously agreed access to Denbury’s pipeline network, threatening the proposed Ascension Clean Energy (ACE) blue ammonia project in Louisiana’s Ascension Parish. ExxonMobil has its own blue hydrogen and ammonia project under development, at Baytown, Texas, although it “paused” it last year, citing weak customer demand and difficulty securing sufficient offtake agreements. ExxonMobil has not publicly commented on the lawsuit.
