For decades researchers have famously said that fusion power is always 30, or even 50, years away. [44] [45] The advent of commercial fusion has changed that, and now fusion power is typically predicted to be around 10 years away, with most companies predicting that the first fusion plant will deliver electricity to the grid before 2035. [46] Although the majority of the companies have only existed for a few years, some have already failed to deliver on their predictions. General Fusion first predicted that it would deliver electricity to the grid by 2009. [47]
Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants. Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as Voyager 2. Energy production from controlled fusion power can potentially eliminate some resource restriction facing fission power, but it is not expected to be commercially available in the near future.
Inertial confinement fusion (ICF) is a fusion energy process that initiates nuclear fusion reactions by compressing and heating targets filled with fuel. The targets are small pellets, typically containing deuterium (2H) and tritium (3H).
Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors. Research into fusion reactors began in the 1940s, but as of 2024, no device has reached net power, although net positive reactions have been achieved.
A nuclear power plant (NPP), also known as a nuclear power station (NPS), nuclear generating station (NGS) or atomic power station (APS) is a thermal power station in which the heat source is a nuclear reactor. As is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity. As of September 2023, the International Atomic Energy Agency reported that there were 410 nuclear power reactors in operation in 32 countries around the world, and 57 nuclear power reactors under construction.
ITER is an international nuclear fusion research and engineering megaproject aimed at creating energy through a fusion process similar to that of the Sun. It is being built next to the Cadarache facility in southern France. Upon completion of construction of the main reactor and first plasma, planned for 2033–2034, ITER will be the largest of more than 100 fusion reactors built since the 1950s, with six times the plasma volume of JT-60SA in Japan, the largest tokamak operating today.
Aneutronic fusion is any form of fusion power in which very little of the energy released is carried by neutrons. While the lowest-threshold nuclear fusion reactions release up to 80% of their energy in the form of neutrons, aneutronic reactions release energy in the form of charged particles, typically protons or alpha particles. Successful aneutronic fusion would greatly reduce problems associated with neutron radiation such as damaging ionizing radiation, neutron activation, reactor maintenance, and requirements for biological shielding, remote handling and safety.
State Atomic Energy Corporation Rosatom, also known as Rosatom State Nuclear Energy Corporation,, or Rosatom State Corporation, is a Russian state corporation headquartered in Moscow that specializes in nuclear energy, nuclear non-energy goods and high-tech products. It was established in 2007 and comprises more than 350 enterprises, including scientific research organizations, a nuclear weapons complex, and the world's only nuclear icebreaker fleet.
A fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state. The condition of Q = 1, when the power being released by the fusion reactions is equal to the required heating power, is referred to as breakeven, or in some sources, scientific breakeven.
Japan is a major consumer of energy, ranking fifth in the world by primary energy use. Fossil fuels accounted for 88% of Japan's primary energy in 2019. Japan imports most of its energy due to scarce domestic resources. As of 2022, the country imports 97% of its oil and is the larger liquefied natural gas (LNG) importer globally.
Hartlepool nuclear power station is a nuclear power station situated on the northern bank of the mouth of the River Tees, 2.5 mi south of Hartlepool in County Durham, North East England. The station has a net electrical output of 1,185 megawatts, which is 2% of Great Britain's peak electricity demand of 60 GW. Electricity is produced through the use of two advanced gas-cooled reactors (AGR). Hartlepool was only the third nuclear power station in the United Kingdom to use AGR technology. It was also the first nuclear power station to be built close to a major urban area.
Since the mid 1980s, the largest source of electricity in France has been nuclear power, with a generation of 379.5 TWh in 2019 and a total electricity production of 537.7 TWh. In 2018, the nuclear share was 71.67%, the highest percentage in the world.
Russia is one of the world's largest producers of nuclear energy. In 2020 total electricity generated in nuclear power plants in Russia was 215.746 TWh, 20.28% of all power generation. The installed gross capacity of Russian nuclear reactors is 29.4 GW in December 2020.
General Fusion is a Canadian company based in Richmond, British Columbia, which is developing a fusion power technology based on magnetized target fusion (MTF). The company was founded in 2002 by Dr. Michel Laberge. The company has more than 150 employees.
TAE Technologies, formerly Tri Alpha Energy, is an American company based in Foothill Ranch, California developing aneutronic fusion power. The company's design relies on an advanced beam-driven field-reversed configuration (FRC), which combines features from accelerator physics and other fusion concepts in a unique fashion, and is optimized for hydrogen-boron fuel, also known as proton-boron or p-11B. It regularly publishes theoretical and experimental results in academic journals with hundreds of publications and posters at scientific conferences and in a research library hosting these articles on its website. TAE has developed five generations of original fusion platforms with a sixth currently in development. It aims to manufacture a prototype commercial fusion reactor by 2030.
Helion Energy, Inc. is an American fusion research company, located in Everett, Washington. They are developing a magneto-inertial fusion technology to produce helium-3 and fusion power via aneutronic fusion, which could produce low-cost clean electric energy using a fuel that can be derived exclusively from water.
LIFE, short for Laser Inertial Fusion Energy, was a fusion energy effort run at Lawrence Livermore National Laboratory between 2008 and 2013. LIFE aimed to develop the technologies necessary to convert the laser-driven inertial confinement fusion concept being developed in the National Ignition Facility (NIF) into a practical commercial power plant, a concept known generally as inertial fusion energy (IFE). LIFE used the same basic concepts as NIF, but aimed to lower costs using mass-produced fuel elements, simplified maintenance, and diode lasers with higher electrical efficiency.
Direct Fusion Drive (DFD) is a conceptual, low radioactivity, nuclear-fusion rocket engine, designed to produce both thrust and electric power, suitable for interplanetary spacecraft. The concept is based on the Princeton field-reversed configuration reactor, invented in 2002 by Samuel A. Cohen. It is being modeled and experimentally tested at Princeton Plasma Physics Laboratory, a U.S. Department of Energy facility, as well as modeled and evaluated by Princeton Satellite Systems (PSS). As of 2018, a direct fusion drive project driven by NASA is said to have entered its simulation phase, presented as the second phase of the concept's evolution.
The history of nuclear fusion began early in the 20th century as an inquiry into how stars powered themselves and expanded to incorporate a broad inquiry into the nature of matter and energy, as potential applications expanded to include warfare, energy production and rocket propulsion.
Zap Energy is an American company that aims to commercialize fusion power through use of a sheared-flow-stabilized Z-pinch. The company is based near Seattle with research facilities in Everett and Mukilteo, Washington. The company aims to scale their technology to maintain plasma stability at increasingly higher energy levels, with the goal of achieving scientific breakeven and eventual commercial profitability.
Last Energy is an American commercial developer of micro-modular nuclear power plants, established in 2019 by Bret Kugelmass as the commercial spinoff of the Energy Impact Center, an American clean energy research institute.
The headline number for this report is that the fusion industry has now attracted over $6 billion in investment.
The company adopted a new approach to building fusion reactors based on patented technology (US8138692) called the Epicyclotron. The company was founded in 2019 and developed a working fusion device in 2021 based on this approach. In October 2021 the company determined through the experimentation work completed and detailed 'particle in cell' modelling of loss mechanisms that the reactor would not scale as initially anticipated (and therefore could not be developed to deliver a net gain fusion reactor). The company is currently exploring the use of this technology they developed in hydrogen isotope separation as part of the fusion fuel cycle.
The standard joke about fusion is that it is 50 years away and always will be.
In this report, 25 companies think the first fusion plant will deliver electricity to the grid before 2035.
