### Introduction
Saltfoss Energy, formerly known as Seaborg Technologies until its rebranding in April 2025, is a Danish scale-up company specializing in advanced nuclear reactor technology. Founded in 2014 in Copenhagen by a group of physicists including co-founders Andreas Vigand Pedersen, Esben Klinkby, and Eirik Eide Pettersen, the company originated from a vision to address climate change through innovative nuclear solutions. Headquartered in Copenhagen, Denmark, with an additional office in South Korea, Saltfoss Energy's mission is to provide abundant, affordable, and low-emission energy by rethinking nuclear power to make it inexpensive, sustainable, and safe enough to out-compete fossil fuels and revolutionize global energy markets.
The company's key focus areas include developing compact molten salt reactors (CMSRs) deployed on floating power barges for modular, factory-built deployment. This approach emphasizes inherent safety, reduced environmental impact, and applications in emerging markets, particularly in Asia and regions with limited grid infrastructure. Saltfoss has expanded its team to around 100 employees, secured strategic partnerships for manufacturing and operations, and is advancing toward commercialization, with initial deployments targeted for the early 2030s amid growing interest in small modular reactors (SMRs) for decarbonization.
### Key Products and Technology
- **Compact Molten Salt Reactor (CMSR)**: A next-generation nuclear reactor using molten fluoride salt as both fuel and coolant, where uranium fuel is dissolved in the liquid salt; this design operates at near-atmospheric pressure, eliminating high-pressure risks associated with traditional solid-fuel reactors.
- **Power Output and Scalability**: Modular units produce 100 MWe each, with power barges configurable from 200 MWe (two reactors) to 800 MWe (eight reactors); operational lifetime of 24 years, with a 12-year fuel cycle where spent fuel is returned to the supplier for processing.
- **Fuel and Efficiency**: Utilizes low-enriched uranium (LEU) or high-assay low-enriched uranium (HALEU) in molten salt form; focuses on resource efficiency with low waste production, potential to reuse nuclear waste, and closure of the fuel cycle; achieves competitive kilowatt-hour pricing through simplified design and factory production.
- **Safety and Design Features**: Inherently safe with no meltdown or explosion risk—fuel salt solidifies into a stable rock if exposed to air, containing radioactivity; passive shutdown in emergencies without active intervention; floating barge deployment reduces on-site construction, enhances transportability via shipyards, and provides resilience to natural disasters.
- **Applications**: Baseload electricity for grids and remote areas; desalination for clean water production; district heating and cooling; generation of carbon-neutral hydrogen, synthetic fuels, and fertilizers; ideal for integration with renewables in hybrid systems or powering industrial processes in developing regions.
