Shell has selectwed KBR's blue ammonia technology for its Blue Horizons low-carbon hydrogen and ammonia project in Duqm, Oman.

This project will utilize KBR's advanced ammonia synthesis loop technology to produce low-carbon ammonia efficiently and cost-effectively.

Under the agreement, KBR will deliver the licensed proprietary engineering design for a 3,000 metric tons per day ammonia plant, which will use hydrogen produced by Shell's Blue Hydrogen technology. This partnership combines KBR’s ammonia synthesis expertise with Shell’s hydrogen production capabilities to create a highly efficient and sustainable facility.

The collaboration with Shell reaffirms KBR's position as a global leader in ammonia technology, with a proven track record of nearly 260 grassroot ammonia plants licensed, engineered, or constructed since 1943.

The Blue Horizons low-carbon hydrogen and ammonia project in Duqm, Oman, is a distinct initiative by Oman Shell. As of July 2024, it has entered the pre-FEED phase, with Wood plc overseeing this stage. The project will produce blue hydrogen and ammonia by processing natural gas and capturing the CO2, which will be stored through a collaboration with Petroleum Development Oman (PDO). This effort supports Oman's Vision 2040 and aims for net-zero emissions by 2050, complementing Shell’s other green hydrogen projects in Oman​.

The world's largest blue ammonia plant, currently under development by QatarEnergy, is the Ammonia-7 project in Mesaieed Industrial City (will have a prod. capacity of 1.2 million tonnes per year, equating to approximately 3,500 metric tons per day, making it the largest of its kind globally)​​​​​​.
