From using different alternative fuels to hybrid electric propulsion systems, many green projects are aimed at reducing carbon dioxide emissions related to offshore operations. But some researchers say that there is a solution that is easier to get than we thought. It is based on the abundant natural metals in the soil. "Thor" is not named after Thor in Nordic mythology, but after a metal element called thorium.

Thorium Molten Salt Reactor (MSR) is a safe, efficient and proven solution. Its working principle is to dissolve thorium (a rich and naturally occurring low-level radioactive metal) in liquid salt. The subsequent chain reaction heats the salt and generates steam to drive the turbine to generate electricity. Obviously, this is the first time that MSR has been integrated into ship design, and Ulstein, a Norwegian shipyard, is responsible for this design, which is famous for its advanced technological innovation.

Using this unique power generation method, Raytheon will remain self-sufficient and generate enough electricity to power four adventure cruise ships at the same time. This will be the main function of Thor, but it is designed as a 3R ship-for supply, research and rescue. This 149 m (489 ft) ship adopts Erstein's widely acclaimed patented X-shaped bow design (the X-shaped bow is specially designed for the commercial shipping field, representing the reverse bow shape of the hull, which can bring maneuverability advantage and maximize the bow space). It not only looks luxurious and sturdy, but also shows top performance.

In addition to laboratories and lecture halls for scientific research, Thor is also equipped with several work boats, autonomous surface ships and even drones. Helicopters can take off and land on the dedicated tarmac. For rescue operations, it is characterized by rescue booms and fire fighting equipment.

The concept of this ship can realize the vision of zero-emission cruise operation. In order to prove its feasibility, Ustan also developed a concept ship named "Sif", which is an ice-class 1C adventure cruise ship. With a capacity of 80 passengers and 80 crew members, it will provide silent and zero-emission exploration tours for remote areas such as the Arctic and Antarctic waters. It will be powered by the next generation battery and use "Thor" as a mobile charging platform at sea.
"Adventure cruise ships operate in increasingly remote and fragile areas. At the same time, the industry is facing increasing pressure from various stakeholders to protect the natural status quo and prohibit the impact of cruise ships on the environment, "said Cathrine Kristiseter Marti, CEO of Ustan.
The representative of Ullstein believes that this multipurpose thorium-powered ship has the ability to lead a "new battery revolution". Jan emblesag, a professor at Norwegian University of Science and Technology, supports this view. He said: "There are too many uncertainties about the future fuel, but we have abundant energy. With the right method, it can be safer, more efficient and cheaper, and has less impact on the environment than any existing alternative energy sources. In my opinion, this is the most feasible and only credible solution to achieve zero emissions under commercial conditions and cost levels. " The concept of "Thor" is the innovation we need to achieve sustainable success at sea. "This is a bold claim, and Raytheon has enough courage to prove it.
