Allseas has published the results of an independent study showing that its small modular reactor (SMR) technology has the potential to transform the Dutch economy while helping to decarbonise global shipping and heavy industry.
The study, carried out by strategy consultancy Roland Berger over seven weeks between September and October 2025, concludes that Allseas’ SMR concept could generate up to €130 billion in value for the Dutch economy by 2050, while creating 35,000–40,000 new jobs.
This economic impact would come from:
-
direct investments by Allseas and its supply chain, and
-
indirect growth across the Dutch industrial and maritime sectors.
At the heart of Allseas’ plan is a 25 MWe / 70 MWth reactor, based on high-temperature gas-cooled reactor (HTGR) technology.
Five-year development plan and strategic value
Allseas launched a five-year development plan in June 2025, targeting initial operations by 2030, in cooperation with NRG PALLAS, TU Delft and other partners.
“Allseas’ small modular reactor is both technologically innovative and strategically valuable for the Netherlands,” said Stephanie Herema, Nuclear Development Project Manager at Allseas.
“With this technology, we can meet the urgent need for stable, clean and affordable energy, while at the same time creating an export product that accelerates the global energy transition.”
Wide range of applications: from ships to industrial clusters
The compact SMR design makes it suitable for deployment across a wide range of applications, including:
-
offshore and commercial vessels,
-
industrial sites such as chemical clusters, steel plants and refineries,
-
data centres and other energy-intensive facilities.
Roland Berger estimates a potential rollout of up to:
-
110 land-based units in the Netherlands, and
-
700 units in the global maritime sector.
Grid relief and major CO₂ reductions
By generating power directly at the point of use, SMRs can help reduce the load on the already stressed Dutch electricity grid. According to the study, this could:
-
avoid up to €12 billion in planned investments in the high-voltage grid between now and 2050.
In terms of emissions, Allseas projects that its SMR technology could deliver annual reductions of:
-
up to 10 megatonnes of CO₂ in Dutch industry, and
-
up to 55 megatonnes of CO₂ in the global maritime sector by 2050.
Combined, this is equivalent to the annual emissions of around 3.5 million Dutch households.
Competitive economics backed by leading institutions
The study also finds that the reactor offers strong cost competitiveness, providing industrial heat at up to 650°C at prices:
-
around 30% lower than gas turbines, and
-
up to 80% cheaper than renewable alternatives for comparable high-temperature heat.
Roland Berger validated its conclusions with several leading Dutch institutions, including TNO, COVRA, Urenco and the Port of Rotterdam.
“As a responsible family-owned company, we always think in the long term,” Herema added.
“The findings of this study highlight the enormous potential of our technology to address today’s challenges and reinforce our commitment to delivering on our five-year plan.”
