ABS has supported a new study on the economics of LNG carriers with nuclear power, introduced at the Gastech 2026 conference. This study focuses on an LNG carrier with a capacity of 174,000 cubic meters equipped with a 20 to 25 megawatt high-temperature gas reactor being developed by Blossom Energy.
Technical Analysis and Evaluation
This research evaluates the ship's layout, propulsion systems, and operational conditions compared to a new LNG-fueled ship. As various regulations may impact operational costs, the economics of this project have been assessed against different sanction scenarios.

Patrick Ryan, Senior Vice President and Chief Technology Officer of ABS, stated: "Nuclear energy has the potential to fundamentally change the economics of commercial transportation, from ship design to long-term operational costs. We are proud to support studies like this that guide the industry beyond theory towards a clearer picture of what nuclear propulsion can bring in practice."
Business Model and Residual Value
The research team also examined a business model in which the reactor is considered a long-term energy asset that can be installed on a second ship after the first ship's useful life ends. This adds to the residual value of the ship.
Shimpi Hamato, CEO of Blossom Energy, stated: "This study provides a quantitative basis for discussing nuclear propulsion in commercial transport. Blossom Energy has contributed its HTGR reference design to this study, and we will continue to collaborate with ABS and industry partners to create the necessary technical and legal infrastructures for practical applications."
This research clearly demonstrates the future potentials for integrating nuclear energy in maritime transport and could be considered a milestone in the transformation of this industry.
