What these terms mean

Every classification on this page, defined. These are controlled-vocabulary terms, so the same word means the same thing on every profile.

Fusion developer
Develops a fusion device or power plant concept. Carries no implication that the device exists or works.
Fusion
Organizations pursuing energy from nuclear fusion, and their dedicated supply chain.
Field-reversed configuration › › Field-reversed configuration
A self-organised plasma ring that generates its own confining field, with no central coil. Compact and high-beta, but stability over long timescales is the open question.
Pulsed magnetic compression › › Pulsed magnetic compression
Repeated compression of a plasma by pulsed magnetic fields, recovering energy directly from the expansion rather than through a steam cycle.
Deuterium–helium-3
Deuterium with helium-3. Most energy released as charged particles rather than neutrons, which allows direct electrical conversion — but helium-3 is vanishingly scarce on Earth.

In Helion Energy’s own words

Quoted from the organisation’s own site as we archived it. Their description of themselves, not ours, and not a claim this site has checked.

The founders of Helion believe that fusion isn’t a fundamental physics problem, but an engineering problem that will be solved by building, testing, and iterating fusion systems and subsystems. By focusing on our true goal - clean, safe, and abundant electricity - we can approach fusion from a new angle.

No. Not all fusion systems require ignition. Helion’s system is designed to operate without relying on the plasma to self-sustain through ignition, enabled by our pulsed operations.

Where Helion Energy sits

Composed from records in this dataset, not from outside research. Every figure below is counted from what the site holds, so it moves when the data does.

Helion Energy is one of 2 organisations in this dataset pursuing frc.

It is one of 103 we hold in US.

It operates 2 devices in this dataset, none of which carries recorded performance figures.

Disclosed equity funding totals $500m across 1 round, which ranks 5 of 14 among organisations here with a disclosed figure.

It also holds 1 award or agreement carrying no cash figure, which are deliberately not added to that total.
