Case Study on Commonwealth Fusion Systems

Commonwealth Fusion Systems (CFS) is a startup company that is working to develop a new type of nuclear fusion reactor. This type of reactor has the potential to provide a clean and virtually limitless source of energy, and CFS is at the forefront of this technological advancement.

Case Study on Commonwealth Fusion Systems - Designing and building fusion energy systems to power the world

Fusion reactions occur when the nuclei of two atoms fuse together to form a heavier nucleus. This process releases a large amount of energy, which can be harnessed to generate electricity. The fuel for fusion reactions is hydrogen, which is abundant and easy to obtain.


CFS was founded in 2018 by a group of scientists and engineers who had previously worked at the Massachusetts Institute of Technology (MIT). The company’s goal is to develop a scalable fusion energy system that can be deployed around the world.


To achieve this goal, CFS is focusing on developing a new type of fusion reactor called a spherical tokamak. This design is based on the tokamak, which is a type of fusion reactor that uses a magnetic field to confine and control the plasma, or superheated gas, in which the fusion reactions occur.

The spherical tokamak design has several advantages over traditional tokamaks. It is smaller and simpler, making it less expensive to build and maintain. It also has the potential to be more efficient, as it can achieve higher plasma temperatures and densities, which are necessary for sustained fusion reactions.


CFS has made significant progress in the development of its fusion reactor. In 2019, the company announced that it had successfully generated plasma in its prototype reactor and achieved record-breaking plasma temperatures. This was a major milestone and demonstrated the viability of the company’s technology.


In addition to its technological advancements, CFS has also attracted significant investment from both private and public sources. In 2020, the company announced that it had raised $115 million in a funding round led by Bill Gates Breakthrough Energy Ventures.


Despite these achievements, CFS still has a long way to go before its fusion energy system is ready for commercial deployment. The company estimates that it will take at least another decade of research and development before its fusion reactor is ready for widespread use.
