A private fusion company developing two reactor classes — a deuterium-tritium spherical tokamak breeder (Hyperion) and an advanced-fuel D–3He tandem mirror burner (Aegis/MetroVolt) — with a neutrons-first development strategy.
Kronos Fusion Energy (KFE) is a private fusion company pursuing a two-product approach to commercial fusion energy. Founded by Priyanca Ford, the company is developing both a near-term deuterium-tritium breeder reactor and advanced-fuel burner systems designed for defence and commercial power applications. KFE’s technical programme is anchored by peer-reviewed publications deposited on Zenodo.[1]
Hyperion is a negative-triangularity spherical tokamak designed to operate with deuterium-tritium fuel. The published design point specifies a fusion gain Q = 3.424, net fusion power of 88.7 MW, plasma current of 9.86 MA, and a toroidal field of 26.49 T using high-temperature superconducting magnets. The spherical torus configuration (low aspect ratio) enables high beta operation in a compact geometry.[2]
Aegis and MetroVolt are two application-specific housings for a single D–3He tandem mirror burner design. Aegis targets fixed defence installation energy supply, while MetroVolt is designed as a compact generator for data centre and commercial power applications. The D–3He fuel cycle produces primarily charged particles, enabling direct energy conversion and drastically reducing neutron flux compared to D–T systems.[3]
KFE follows a “neutrons first” development strategy, prioritising the D–T breeder as the near-term product that validates physics and engineering while producing neutrons for isotope applications and tritium breeding. The advanced-fuel burner represents the longer-term commercial vision. The company’s technical work spans plasma physics simulation, magnet design, blanket engineering, and tritium systems, with findings published in a series of Zenodo-deposited technical papers.
