MIT researchers tackle the economic realities of fusion power

In the past decade, scientists have proven that fusion energy can function as a physical process. However, a critical question remains: Can it become economically viable? A study co-authored by MIT professors Dennis Whyte and Andrew W. Lo seeks to address this issue by proposing a framework for understanding the requirements for commercially viable fusion energy.

The framework takes into account the physical inputs required to sustain controlled fusion energy production, as well as the costs of constructing power plants that can compete in energy markets. Dennis Whyte, a professor of nuclear science and engineering at MIT, emphasizes the importance of addressing economic aspects of fusion energy.

He explains that the goal is to create a clear framework for understanding the economic aspects of fusion energy, which will help determine if it can make a meaningful impact in the world economy. The framework consists of 10 parameters, including scientific and physical aspects, such as the ratio of fusion power produced to the external power required (known as the "plasma Q"), and engineering and economic factors like plant construction costs.

Lawrence Lo, a professor of finance at the MIT Sloan School of Management, highlights the challenge of translating complex scientific and engineering requirements into economic consequences. He stresses that without addressing these economic factors, it will be difficult to secure the necessary funding for fusion energy research.

The paper, titled "Criteria for the economic viability of fusion power plants," has been published online in the Journal of Fusion Energy.
