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.

EU to suspend import duties

The European Commission (EC) officially proposed to suspend, for one year, the most favoured nation (MFN) duties on imports of several key nitrogen-containing fertilizers and inputs for their production, including ammonia and urea, officials said 24 February. The tariff suspension will be implemented for all countries, except Russia and Belarus, through duty-free tariff rate quotas, the Commission noted. Imports beyond these quotas will be subject to standard MFN duties, it added.
