A new design for an ammonia floating production storage and offloading unit that features onboard carbon capture technology for blue ammonia production has received approval in principle from ABS.

The design comes from MODEC, Inc. (MODEC), in collaboration with Toyo Engineering Corporation (TOYO). ABS completed design reviews based on class and statutory requirements.

Blue ammonia is a low-carbon method of producing ammonia. It is produced by combining hydrogen, which is derived as a byproduct of carbon dioxide that has been captured and stored, with nitrogen.

“Blue ammonia has significant potential to lower the emissions of offshore operations. ABS is able to harness its extensive experience offshore alongside its global leadership in the classification of FPSOs to support the development of this potentially game-changing technology,” said Miguel Hernandez, ABS Senior Vice President, Global Offshore.

“Through this development, we have explored how we can leverage our expertise in producing low-GHG ammonia, a potential alternative energy source to oil and gas in the global energy mix. However, this development has also made us aware of the significant challenges that need to be tackled to commercialize the concept,” said Koichi Matsumiya, MODEC Inc., Executive Officer, Group CTO.

“MODEC views this AIP as the first step in developing floating solutions for alternative energy production. We will continue to strive to refine and mature this concept, pursuing a safe and affordable alternative energy supply solution. This is part of our commitment to society to explore a sustainable future with innovation.”

“We are proud to announce that TOYO, with its extensive expertise and a global track record of 87 ammonia projects, has successfully obtained AIP from ABS for the ammonia FPSO jointly developed with MODEC. The innovative design of the ammonia FPSO enables offshore production of blue ammonia, a low-environmental impact fuel that is expected to contribute significantly to mitigating global warming. By advancing the efficient use of resources and supporting the transition to a decarbonized society, we remain committed to driving sustainable energy solutions for the future,” said Eiji Hosoi, TOYO President and CEO.
