Three nuclear energy plants owned by Constellation Energy Nuclear Group LLC have officially joined Exelon Generation's fleet of nuclear plants, expanding what was already the U.S.'s largest commercial nuclear operation.

The three CENG plants include five reactors capable of generating more than 4,200 megawatts at full power. They include:

  • R.E. Ginna Nuclear Power Plant in Ontario, N.Y., a single 583-megawatt pressurized water reactor.
  • Nine Mile Point Nuclear Station in Scriba, N.Y., two boiling water reactors totaling 1,937 megawatts.
  • Calvert Cliffs Nuclear Power Plant in Lusby, Md., two pressurized water reactors totaling 1,768 megawatts.

The NRC approved license transfers for the three plants on Tuesday, March 25.   

The consolidation, which followed the March 2012 merger between Exelon and Constellation Energy Group Inc., expands the fleet of reactors Exelon operates to 23 nuclear generating units at 14 locations in Illinois, Pennsylvania, Nebraska, New York, New Jersey, and Maryland. The 23 units have the capability to generate more than 22,000 megawatts.

Michael J. Pacilio, Exelon Nuclear's president and chief nuclear officer, will lead the newly expanded fleet, which will operate under Exelon Nuclear's management model, a driver of success and consistent operations at all stations. Maria G. Korsnick will remain chief nuclear officer of CENG.

The consolidation is an organizational and operational re-alignment, not a purchase or transfer of assets. Electricite de France (EDF) and Exelon remain co-owners of CENG, with Exelon owning 50.01 percent of CENG and EDF 49.99 percent. CENG remains governed by a board of directors comprising five representatives from EDF and five from Exelon. Exelon Senior Executive Vice President and Chief Strategy Officer, William A. Von Hoene, Jr., also becomes chairman and CEO, CENG.

Exelon Corp. and Constellation Energy completed their merger on March 12, 2012. Through that union, Exelon became EDF's joint venture partner in CENG and also the leading U.S. competitive energy provider, with one of the cleanest and lowest-cost power generation fleets and largest retail customer bases in the nation.

Trafigura and Yara International explore clean ammonia usage

Commodity trading company Trafigura and Yara International sign MoU to explore developing ammonia as a clean fuel in shipping

Independent commodity trading company Trafigura and Yara International have signed an MoU to explore developing ammonia as a clean fuel in shipping and ammonia fuel infrastructure.

Reducing shipping emissions is a vital component of the fight against global climate change, yet Greenhouse Gas emissions from the global maritime sector are increasing - and at odds with the IMO's strategy to cut absolute emissions by at least 50% by 2050. 

How more than 70,000 ships can decrease their reliance on carbon-based sources is one of transport's most pressing decarbonisation challenges.

Yara and Trafigura intend to collaborate on initiatives that will establish themselves in the clean ammonia value chain. Under the MoU announced today, Trafigura and Yara intend to work together in the following areas:

  • The supply of clean ammonia by Yara to Trafigura Group companies
  • Exploration of joint R&D initiatives for clean ammonia application as a marine fuel
  • Development of new clean ammonia assets including marine fuel infrastructure and market opportunities

Magnus Krogh Ankarstrand, President of Yara Clean Ammonia, said the agreement is a good example of cross-industry collaboration to develop and promote zero-emission fuel in the form of clean ammonia for the shipping industry. "Building clean ammonia value chains is critical to facilitate the transition to zero emission fuels by enabling the hydrogen economy – not least within trade and distribution where both Yara and Trafigura have leading capabilities. Demand and supply of clean ammonia need to be developed in tandem," he said.  

There is a growing consensus that hydrogen-based fuels will ultimately be the shipping fuels of the future, but clear and comprehensive regulation is essential, according to Jose Maria Larocca, Executive Director and Co-Head of Oil Trading for Trafigura.

Ammonia has a number of properties that require "further investigation," according to Wartsila. "It ignites and burns poorly compared to other fuels and is toxic and corrosive, making safe handling and storage important. Burning ammonia could also lead to higher NOx emissions unless controlled either by aftertreatment or by optimising the combustion process," it notes.

Trafigura has co-sponsored the R&D of MAN Energy Solutions’ ammonia-fuelled engine for maritime vessels, has performed in-depth studies of transport fuels with reduced greenhouse gas emissions, and has published a white paper on the need for a global carbon levy for shipping fuels to be introduced by International Maritime Organization.

Oslo-based Yara produces roughly 8.5 million tonnes of ammonia annually and employs a fleet of 11 ammonia carriers, including 5 fully owned ships, and owns 18 marine ammonia terminals with 580 kt of storage capacity – enabling it to produce and deliver ammonia across the globe.

It recently established a new clean ammonia unit to capture growth opportunities in emission-free fuel for shipping and power, carbon-free fertilizer and ammonia for industrial applications.
