Ascension Clean Energy (ACE), which is planning a $7.5 billion, 7.2 million mt/y low carbon ammonia plant in Ascension Parish, La. (GM Nov. 4, p. 1), has selected Danish technology provider Topsoe for its project. ACE will use Topsoe’s integrated hydrogen and ammonia solutions, including SynCOR™ autothermal reforming (ATR) technology. The project expects to achieve up to 98% of carbon capture, with the CO2 permanently sequestered by Denbury Carbon Solutions.
ACE is a joint venture of recent startup Clean Hydrogen Works (CHW), which is the majority shareholder; Denbury Carbon Solutions, a subsidiary of Denbury Inc., the largest CO2 pipeline operator in the US; and Hafnia, a major oil product and chemical tanker company.
The project will be on the West Bank of the Mississippi River and will be on a 1,700-acre site near existing infrastructure, with direct access to the river. The project is expected to create 350 permanent, full-time jobs.
ACE said approximately 75% of the planned ammonia production volume is supported by letters of intent for offtake agreements with high-quality purchasers. Two ammonia blocks are currently projected to start up in a staged approach, with Block 1 production anticipated to commence in 2027.
A final investment decision regarding ACE is expected in 2024.
