  • UK Atomics

    UK Atomics and its parent company Copenhagen Atomics is revolutionizing the global energy system by introducing a unique thorium molten salt reactor that offers unbeatable price/performance. With a thermal output of 100 MW per reactor, it is ideal for power production and industrial applications such as process heat, hydrogen and ammonia production. To increase the output for larger production, the modular nature of the reactors allows for additional reactors to be placed together. It can be built and deployed anywhere in the world, thanks to its compact size and assembly line production.


    This innovative technology can utilize spent fuel waste from conventional nuclear reactors, while also drastically reducing the amount of final waste generated. With an aggressive roadmap to commercial operation by 2028, Copenhagen Atomics is leading the way in developing a green energy solution.


    To make this solution accessible to customers, Copenhagen Atomics offers an innovative “Energy-as-a-Service” business model. This model enables customers to access clean, low-cost energy without any up-front costs.


    Implementing this technology will drive several key objectives, including enhancing national energy security by reducing dependence on energy imports. It provides financial growth opportunities for industries by offering low-cost green energy and supports the transition off fossil fuels to meet global green targets.


    With a vision to provide green energy for 1 billion people and to drive growth and prosperity for mankind, Copenhagen Atomics is committed to disrupting the way new solutions are developed and scaling this technology to impact the world.
