Century-Long Quest for Fusion Energy: Pursuit from Aston to Tokamak Technologies
A Century of Fusion Energy Research: From Aston's Discovery to ITER
The history of fusion energy research, spanning a century from the 1920s to the present day, began with Francis William Aston's groundbreaking discovery of the mass defect in atomic nuclei. This revelation laid the theoretical foundation for fusion as a potential energy source, as it demonstrated that mass could convert to energy—a concept later described by Einstein's famous equation, E=mc² [1][2].
In the 1920s, Aston meticulously measured the mass defect in atomic nuclei, providing the first evidence of mass-energy conversion fundamental to fusion energy. Simultaneously, Einstein's mass-energy equation was formulated, providing the guiding principle for fusion science [1][3].
The 1930s to the 1950s saw early fusion research focusing on understanding stellar processes. Post-World War II, fusion gained attention for energy generation, particularly during the Cold War's secretive military research. Various experimental devices were developed, including magnetic confinement concepts like the stellarator and tokamak designs, which originated in the Soviet Union in the 1950s-60s [1].
The tokamak, a doughnut-shaped device for magnetic confinement, became a pivotal contribution to fusion research in the 1960s. Each new reactor, such as JET in the UK, TFTR at Princeton, and JT-60 in Japan, pushed the boundary further, but none could achieve breakeven [1][2].
The 1960s to the 1980s saw the tokamak become dominant due to its superior plasma confinement. International fusion efforts expanded despite technical challenges achieving net energy gain. Magnetic confinement fusion research grew worldwide, including devices like magnetic mirrors and laser-based inertial confinement fusion (ICF) [1][2].
The approach of ICF emerged in parallel with magnetic confinement, promising a more compact and scalable route to fusion. However, it faced challenges in achieving the necessary symmetry of implosion and minimizing energy loss [1][2].
The 1990s to 2000s saw advancements in laser ICF and magnetic confinement tokamaks continue. Novel concepts such as "fast ignition" and private sector participation emerged. The U.S., China, South Korea, and others joined the ITER project, which began as a multinational collaboration to build the largest tokamak reactor, aiming for net energy production with long-pulse fusion plasmas [1][2].
ITER, located in southern France and funded by a consortium including the EU, U.S., China, Russia, Japan, South Korea, and India, stands as the most ambitious multinational fusion endeavour. Despite persistent scientific and engineering hurdles, the vision traces directly back to Aston’s mass defect discovery and the century-long quest to harness the power of the stars on Earth [1].
Fusion research has been a victim of its own grandeur, being too big for private enterprise, too long-term for electoral politics, and too scientific for popular understanding. Fusion's budgets fluctuated with oil prices, national anxieties, and shifting partisan priorities, making it a soft target for funding cuts despite its long-term promise [1].
Despite decades of work and billions in investment, ICF too fell short of ignition, even as it generated increasingly sophisticated diagnostics and simulations. Fusion research became a multinational enterprise by the late 20th century [1].
ITER will not produce electricity, but it is a proof of concept for the next generation of fusion reactors. The International Thermonuclear Experimental Reactor (ITER) seeks to demonstrate sustained fusion at energy gain, but exemplifies the bureaucratization of science, with its timeline extending by decades, costs ballooning, and geopolitical consensus remaining fragile [1].
The hydrogen bomb, or thermonuclear weapon, demonstrated fusion reactions could be initiated in Earth-bound conditions in 1952, but the challenge became clear: how to tame the sun's violence for peaceful purposes [1]. The challenge of taming fusion for peaceful purposes has proved difficult, with technical demands exceeding those of fission reactors and funding depending on Cold War patronage [1].
