Advancing the Next Generation of Clean Maritime Power
TEMISTh is proud to participate in the Fusion Power Barge (FusPoB) Joint Industry Project, an ambitious international initiative assessing the feasibility of deploying a compact nuclear fusion reactor aboard a marine vessel.
Announced at Posidonia 2026 in Athens, the project brings together leading organizations from the maritime, energy, and engineering sectors, including American Bureau of Shipping (ABS), nT-Tao, Siemens Energy, P&P Marine Consultants, and TEMISTh.
The consortium will conduct a comprehensive two-year feasibility study covering engineering integration, safety, classification requirements, regulatory pathways, and commercial viability. The ultimate objective is to evaluate the potential deployment of a fusion-powered vessel by approximately 2032.
Bringing Fusion Energy to the Maritime Sector
Nuclear fusion is widely regarded as one of the most promising energy technologies for achieving long-term, large-scale decarbonization. By replicating the same physical process that powers the sun, fusion has the potential to generate significant amounts of energy with minimal environmental impact.
The FusPoB project aims to investigate the integration of nT-Tao’s compact pulsed stellarator fusion reactor into a dedicated offshore power vessel. The proposed platform would not only provide propulsion capabilities but also supply electricity to offshore facilities and support freshwater production through desalination systems.
If successful, the project could represent a major step forward in the development of carbon-free energy solutions for maritime and offshore applications.
A Pioneer Project with Global Significance
The vessel concept developed within FusPoB is based on a 71.4-meter DP2-anchor handling power barge supply vessel designed by P&P Marine Consultants.
Powered by two 8 MW steam generators driven by nT-Tao’s fusion reactor technology, the vessel would provide:
- Offshore power generation
- Ocean towing capabilities
- Desalinated water production
- Electric propulsion
- Enhanced operational flexibility through battery backup systems
Beyond the vessel itself, FusPoB seeks to establish the world’s first classification and regulatory framework dedicated to floating fusion energy installations. This work is being led by ABS and represents a critical step toward the future adoption of fusion technologies within the maritime industry.
Thermal Engineering at the Heart of Fusion Energy
One of the most significant engineering challenges associated with fusion systems is thermal management.
Converting fusion-generated heat into useful electrical power requires highly efficient heat transfer systems capable of operating under demanding conditions. The performance, safety, and economic viability of any fusion installation depend heavily on the effectiveness of its thermal architecture.
Key challenges include:
- Heat extraction and transport
- Thermal efficiency optimization
- Cooling of critical systems
- Steam generation and power conversion
- Safety-related heat dissipation
- Integration within compact marine environments
These challenges make advanced thermal engineering a fundamental component of the FusPoB feasibility study.
