Allseas has developed a five-year plan to design, develop and deploy a small modular reactor (SMR) that can be integrated into offshore vessels and used onshore.
The move into nuclear, Allseas said, “marks the next bold step – delivering clean, high-performance energy systems to sea and shore”. It added that nuclear offers unmatched energy density, combining zero emissions with stable, scalable power supply.
Onshore, industrial clusters face high energy costs, grid congestion and volatile renewable supply. SMRs can ease grid pressure while providing consistent, carbon-free power and heat – accelerating decarbonisation and boosting industrial resilience and long-term competitiveness, said Allseas. It has selected high-temperature gas-cooled reactors (HTGRs) in the 25 MWe range, due to their inherently safe characteristics. This fourth-generation reactor technology generates energy without combustion or emissions.
As part of its roadmap, in the first year Allseas will finalise initial design studies for offshore and onshore use. This will be followed by prototype development and pre-licensing discussions in consultation with key stakeholders, including the Dutch Authority for Nuclear Safety and Radiation Protection (ANVS), International Maritime Organization (IMO), International Atomic Energy Agency (IAEA) and Lloyd’s Register, as well as the company’s research and innovation partners.
“Our goal is to start production at a dedicated facility by 2030,” said Stephanie Heerema, project manager nuclear developments at Allseas. “Initial deployment will likely begin on land while offshore regulations are finalised, followed by application on our own vessels and broader industry adoption. This aligns with our own sustainability targets – 30 percent emissions reduction by 2030, and net-zero operations by 2050.”
