Exxon in legal case over pipeline access


Exxon in legal case over CO2 pipeline access

ExxonMobil has been named by Clean Hydrogen Works as an additional defendant in an 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.

The issues are: overestimation of production by almost 27,000 t last year; a multimillion-dollar renovation of the company’s headquarters in Santiago; and, maybe, the collapse of a chimney at Potrerillos copper smelter in the Atacama region of northern Chile. The structural failure has forced a production suspension.
