The energy to transform

"Expedition cruise ships operate in increasingly remote, and environmentally fragile, areas. At the same time, the industry faces growing pressure from diverse stakeholders to preserve nature as it is and ban the environmental impact of cruising. 'Thor' enables replenishment of energy and supplies on site, while also boasting the technology to facilitate rescue operations, as well as conducting research tasks. It is, in effect, a crucial piece of infrastructure to support sustainable and safer operations. 'Thor' literally has the power to change our entire industry," states Marti

The energy to transform

Thorium has been identified as having huge potential for a maritime industry hunting for clean alternative fuels.

MSRs are safe, efficient and operationally proven solutions that work by dissolving Thorium ? an abundant, naturally occurring metal with low radioactivity ? in liquid salt. The ensuing chain reaction heats the salt, producing steam to drive a turbine and create electricity. Although developments on land are well documented, its potential for delivering clean maritime power has yet to be incorporated into a vessel design. Ulstein, famed for innovating the revolutionary X-BOW® design, has seen an opportunity to change that, potentially heralding a new dawn of clean power for cruise and maritime operations.

'Thor's' charging capacity has been scaled to satisfy the power needs of four expedition cruise ships simultaneously. 'Thor' itself would never need to refuel. As such, 'Thor' is intended to provide a blueprint for entirely self-sufficient vessels of the future

Generating excitement

Speaking about the suitability of Thorium MSRs as an energy source for maritime applications, Jan Emblemsvåg, Professor at the Norwegian University of Science and Technology, an expert in the field of Thorium and nuclear power generation, notes: "MSRs have enormous potential for enabling clean shipping. There is so much uncertainty over future fuels, but here we have an abundant energy source that, with the right approach, can be safe, much more efficient, cheaper, with a smaller environmental footprint than any existing alternative."

"From my perspective, I see this as the most viable, and potentially the only credible, solution for a zero-emission fleet that can operate under commercial terms and cost levels. The 'Thor' concept is exactly the kind of innovation we need for sustainable success at sea."

An urgent conversation
 

Both 'Thor' and 'Sif' feature Ulstein's eye-catching X-BOW® design, created for greater operability, comfort, operational functionality and fuel efficiency.

'Thor' features helicopter pads, firefighting equipment, rescue booms, workboats, autonomous surface vehicles and airborne drones, cranes, laboratories, and a lecture lounge.

The expedition cruise vessel 'Sif' can accommodate up to 80 passengers and 80 crew, offering silent, zero-emission expedition cruises to remote areas, including Arctic and Antarctic waters.
