List of nuclear fusion companies

Commercial fusion is a term used to refer to privately or publicly held companies which aim to sell electricity produced by nuclear fusion. The industry now consists of over 40 companies that have attracted a combined total of more than $7 billion in investment.[1][2]

Commercial fusion companies

Companies pursue various different fusion methods for reactors. Some pursue one method, such as magnetic, inertial, or electrostatic confinement. Some pursue hybrid methods such as magneto–inertial or magneto–electrostatic confinement. More methods exist; see below:

First fusion electricity to the grid

For decades researchers have famously said that fusion power is always 30, or even 50, years away.[101][102] The advent of commercial fusion has changed that, and now fusion power is typically forecast to be around 10 years away, with most companies forecasting that the first fusion plant will deliver electricity to the grid before 2035.[103] Although most of the companies have existed for only a few years, some have already failed to deliver on their forecasts. General Fusion first forecast that it would deliver electricity to the grid by 2009.[104]

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.
