Delft, The Netherlands — November 2025 — Allseas, a global leader in offshore engineering technologies, together with strategic consultancy Roland Berger, has published a comprehensive impact study on the potential of a next-generation small modular reactor (SMR) concept. The study shows that Allseas’ compact SMR design could deliver major benefits to the Dutch economy, industrial decarbonisation efforts and long-term energy security.

Developed through technical assessments, economic modelling and multi-stakeholder validation, the study provides the most complete analysis to date of this SMR concept.

SMR Concept: High-Temperature, Modular and Fit for Both Onshore and Maritime Use

The SMR proposed by Allseas is based on a high-temperature gas-cooled reactor (HTGR) using TRISO fuel, producing approximately 25 MWe (70 MWt). Key features include:

• Industrial-grade heat supply up to ~650°C

• Inherent safety characteristics aligned with next-generation nuclear requirements

• Modular fabrication, supporting scalable and cost-efficient deployment

• Integration potential for offshore platforms and vessels, supporting maritime decarbonisation

This combination positions the SMR as a solution bridging the gap between intermittent renewables and the stable high-temperature needs of energy-intensive industries.

Economic Impact: Up to €130 Billion in Added Value

According to Roland Berger, by 2050 the technology could yield:

• ~€130 billion in cumulative added value to the Dutch economy

• 10,000–15,000 existing jobs supported

• 35,000–40,000 new jobs in nuclear technology, maritime systems and advanced manufacturing

Localised SMR deployment could also reduce the need for costly grid upgrades, easing pressure on the national electricity system.

Strong Decarbonisation Benefits

Because the SMR design can serve both onshore industrial clusters and maritime operations, emissions reductions could be substantial:

• ~10 million tonnes of CO₂ avoided annually in Dutch industry

• ~55 million tonnes annually in global maritime applications

These figures represent emissions comparable to those of several million households.

Strategic Value for the Netherlands

The study highlights two key strategic strengths:

1. Decentralised, stable, low-carbon power generation

2. Direct supply of high-temperature heat, reducing reliance on natural gas and subsidy-dependent renewable heat sources

Deployed at ports, industrial hubs or offshore infrastructure, SMRs could become a cornerstone of Dutch energy security and industrial competitiveness.

Challenges and Next Steps

The study also notes key factors required for commercialisation:

• Regulatory licensing and safety demonstration

• Long-term fuel-cycle and waste-management solutions

• Clear international standards for maritime nuclear applications

Allseas has outlined a five-year plan including prototype development, onshore and offshore application studies, safety research with leading institutions, and early-stage regulatory engagement. The company aims to establish its first modular production facility before 2030, depending on regulatory progress.

Statements from Allseas and Roland Berger

Allseas project leadership commented:
“This study provides a robust factual basis for advancing our nuclear technology programme and reinforces the strategic value of compact SMRs.”

Roland Berger concluded:
“A safe, scalable and high-temperature SMR could become a key driver of Dutch industrial competitiveness and long-term energy resilience.”
