Problem
Maritime freight vessels rely on fossil fuel engines that emit large amounts of CO₂ and require frequent refueling, limiting both environmental sustainability and operational autonomy.
Solution
Aronnax develops compact nuclear reactors designed for integration into freight ships, providing a clean, reliable power source that eliminates CO₂ emissions from propulsion. The reactors incorporate passive safety systems, which are easier to achieve at small scales in marine environments, and are built for a 60‑year operational lifetime, reducing the need for refueling and maintenance. By delivering redundant propulsion capability, the technology enhances safety at sea while offering a lower total cost of ownership compared to conventional diesel engines. The solution enables continuous, high‑energy output for long voyages, supporting decarbonization goals and improving energy security for the shipping industry.
Target Audience
Primary customers are owners and operators of large‑scale freight shipping companies seeking to decarbonize their fleets and improve operational efficiency.
