Fusion Power on Ships: The Future of Maritime Energy?
Developing a Maritime Fusion Reactor: A Step Towards Clean Energy

The Future of Clean Energy: Nuclear Fusion and Technical Challenges
A startup company intends to develop a fusion reactor aboard a ship, a bold step towards achieving clean energy. Nuclear fusion is a process where two light atomic nuclei combine to form a heavier nucleus, releasing immense amounts of energy—the same process that powers the sun and stars. Thanks to recent advancements in Artificial Intelligence, computing, and superconducting magnets, nuclear fusion energy is closer than ever to commercial reality, promising to provide large quantities of clean energy from an abundant source: water.

From Fission to Fusion Reactors: The Precedent of Nuclear Ships
The idea of placing a nuclear reactor on a ship is not entirely new; current nuclear fission reactors on submarines and aircraft carriers paved the way for this concept. These vessels offer immense capabilities with quiet operation and can operate for decades before needing refueling. Fusion technology aims to provide similar capabilities for ships but without the concerns associated with nuclear meltdown, nuclear weapon proliferation, or radiation.

Maritime Fusion: A Maritime Strategy for Commercial Viability
Maritime Fusion, led by Justin Kroll, is a pioneer in exploring the possibility of placing tokamak reactors (a leading fusion reactor design) aboard ships. Kroll believes that starting at sea may be commercially easier, as competing with the costs of solar and wind energy on the terrestrial power grid represents a significant challenge. Meanwhile, in the maritime environment, economic viability is different; alternative marine fuels like ammonia and hydrogen are still extremely expensive, opening the door for nuclear fusion to compete directly in the maritime energy market.

Funding and Manufacturing of "Yinsen": Project Details and Timeline
Initial Funding Round
Maritime Fusion raised $4.5 million
Manufacturing HTS Cables
Assembling High-Temperature Superconducting (HTS) cables
Additional Revenue
Plan to sell cables to other companies
Yinsen Reactor Capacity
Expected to generate around 30 megawatts of electricity
Reactor Size
Approximately eight meters wide
Target Service Date
2032 with an estimated cost of $1.1 billion
Maritime Fusion has raised $4.5 million in an initial funding round, led by Trucks VC, to advance its concept and build components for its first reactor. The company is currently assembling High-Temperature Superconducting (HTS) cables from sourced materials, which will form the basis of the powerful magnets needed to contain plasma for fusion reactions. The company also plans to sell these cables to other companies to generate revenue while developing its fusion power plant.

The company's first reactor, named "Yinsen", is expected to generate approximately 30 megawatts of electricity. To simplify onboard equipment, some auxiliary tasks, such as fuel processing, will be carried out ashore. Maritime Fusion's first tokamak reactor is expected to be about eight meters wide and is targeted to enter service in 2032 at an estimated cost of about $1.1 billion.

Maritime Fusion's Competitive Advantage in the Fusion Race
Despite other leading companies in the nuclear fusion field, such as Commonwealth Fusion Systems (CFS), which is building the smaller Sparc reactor, Maritime Fusion is confident in its innovative approach. While CFS's Sparc reactor aims to prove that tokamak reactors can generate more energy than they consume without initially connecting to the grid, Kroll emphasizes that Maritime Fusion's first reactor will be an energy-producing device for a direct customer, highlighting the commercial focus of its business model.
