The history of fusion energy research is briefly reviewed, followed by a detailed discussion of Kronos Fusion Energy's S.M.A.R.T 40 Aneutronic Fusion Energy Device, which is designed to achieve Q40 and enable widespread commercialization of fusion energy.
1 - Introduction
Fusion energy has long been considered the holy grail of clean, sustainable energy production. With the potential to provide abundant power with minimal environmental impact, fusion energy has the ability to revolutionize the global energy landscape. Achieving a Q40 energy output – where the energy produced by a fusion reactor is 40 times greater than the energy required to sustain the reaction – is a critical milestone for the commercialization of fusion energy.
2 - A Brief History of Fusion Energy Research
Fusion energy research began in earnest during the 1950s, driven by the potential for a nearly limitless source of clean energy. Early experimental reactors, such as the ZETA device in the UK, demonstrated the potential of fusion energy, but also highlighted the significant technical challenges associated with achieving and sustaining a controlled fusion reaction.
Over the following decades, numerous advances were made in reactor design and plasma confinement techniques, with tokamaks and stellarators emerging as the dominant concepts. Despite significant progress, a self-sustaining fusion reaction with a Q40 energy output remained elusive.
Fusion energy research commenced in the 1950s, motivated by the prospect of an almost inexhaustible source of clean energy. Early experimental reactors, including the ZETA (Zero Energy Thermonuclear Assembly) device in the UK, showcased the potential of fusion energy. However, they simultaneously revealed substantial technical challenges related to initiating and maintaining a controlled fusion reaction.
In the 1960s, researchers made significant strides in understanding plasma behavior and confinement. This period saw the development of the magnetic mirror concept by Richard F. Post at the Lawrence Livermore National Laboratory and the invention of the tokamak by Soviet physicists Igor Tamm and Andrei Sakharov. The tokamak, with its toroidal geometry and efficient plasma confinement, quickly became the leading fusion reactor design.
During the 1970s and 1980s, the focus of fusion energy research shifted toward refining and scaling up tokamak designs. Major facilities such as the Joint European Torus (JET) in the UK and the Tokamak Fusion Test Reactor (TFTR) in the United States were constructed, yielding valuable insights into plasma behavior and reactor engineering.
The stellarator concept, originally proposed by Lyman Spitzer in the 1950s, gained renewed interest in the 1980s and 1990s. Stellarators employ a twisted magnetic field configuration for plasma confinement, offering inherent steady-state operation and reduced plasma instabilities compared to tokamaks. Advanced stellarator designs, such as the Wendelstein 7-X in Germany, have shown promising results and continue to be explored as an alternative to tokamak reactors.
In parallel with advancements in reactor design and plasma confinement techniques, researchers also investigated alternative fusion fuel cycles. Aneutronic fusion reactions, such as proton-boron-11 (p-B11) and deuterium-helium-3 (D-He3), gained attention due to their reduced neutron production and potential for direct energy conversion, improving the overall efficiency and safety of fusion reactors.
Throughout these decades of research, achieving a self-sustaining fusion reaction with a Q40 energy output proved to be an elusive goal. However, recent breakthroughs in material science, advanced simulation techniques, and engineering innovations have brought the fusion energy community closer than ever to this critical milestone.
