Request a Briefing Access the Audit PortalKronos Fusion Energy is an independently funded fusion-energy company developing compact, low-neutron fusion generators for dispatchable, fuel-secure power. It operates from Los Angeles and Switzerland under the MetroVolt and AEGIS program, built on the Kronos S.M.A.R.T. architecture.
Two product lines on one reactor architecture: MetroVolt, a compact fusion generator for commercial urban-grid power, and AEGIS, a version for defense applications. Both are based on the Kronos S.M.A.R.T. (Superconducting, Minimum-Aspect-Ratio Torus) architecture.
S.M.A.R.T. stands for Superconducting, Minimum-Aspect-Ratio Torus — a high-field, compact spherical tokamak using advanced REBCO high-temperature superconducting magnets and multi-modal direct energy conversion.
Kronos operates from a Los Angeles headquarters and a Switzerland engineering hub.
Kronos Fusion Energy was incorporated in 2022. Its founder's underlying energy and fusion research predates the company.
Kronos targets commercialization by 2032.
Conventional deuterium–tritium (D–T) fusion releases roughly 80% of its energy as high-energy neutrons, which damage materials and create radioactive waste. Kronos uses a deuterium–helium-3 (D–³He) fuel cycle designed to keep neutron output low, which reduces material damage, waste, and shielding needs and enables direct energy conversion.
No — and we deliberately say low-neutron, not aneutronic. A D–³He cycle still produces some neutrons from unavoidable D–D side reactions. Our design minimizes that to a low neutron fraction (roughly 5–7%) rather than claiming zero. Precise language is part of how we operate.
It confines a D–³He plasma in a compact, high-field spherical tokamak using advanced REBCO superconducting magnets, shapes the plasma with negative triangularity for stability, and recovers energy from charged particles directly via a multi-modal direct energy conversion train rather than relying solely on a steam cycle.
A deuterium–helium-3 (D–³He) fuel cycle. Rather than depending on scarce, externally procured helium-3, the design breeds its own ³He internally through a staged, catalyzed D–D schedule — reducing geopolitical and supply-chain risk.
DEC captures the kinetic energy of charged fusion products (protons and alphas) and converts it to electricity directly, using traveling-wave DEC grids and electrostatic collectors — bypassing the losses of a conventional steam cycle for the charged fraction and raising overall efficiency.
The design point uses a field-graded REBCO superconductor pack reaching a peak field around 24.6 T, engineered to keep conductor strain within safe limits.
The design targets a low neutron fraction of roughly 5–7% of fusion power, compared with about 80% for conventional D–T designs — substantially reducing shielding, activation, and waste.
Fusion cannot melt down or run away — stopping the fuel supply stops the reaction. Kronos adds an eight-layer control architecture with hardwired protection tiers and unidirectional data paths designed to contain single-point control failures.
Negative triangularity is a plasma shape that suppresses edge-localized modes (ELMs) — destructive bursts of energy — while maintaining good confinement. It protects the direct-energy-conversion hardware and improves stability.
The MetroVolt conceptual design is published as a multi-part scientific series on arXiv and prepared for peer review in the journal Nuclear Fusion. The complete validation dataset is openly deposited for independent verification.
Yes. Kronos has openly deposited its complete 81-simulation validation package on Zenodo (DOI: 10.5281/zenodo.21248916), including free-boundary equilibria, gyrokinetic transport modeling, 3-D neutronics, and bottom-up cost curves. Anyone can download and run the code.
The validation baseline spans free-boundary MHD equilibria (FreeGS), gyrokinetic transport modeling, OpenMC 3-D neutronics, and bottom-up, learning-curve cost modeling — assembled into an end-to-end consistency chain.
Yes. Kronos's technology is protected by U.S. Patent 12,009,112 ("Fusion generator") and pending application 17/878,550, co-invented by founder Priyanca Ford with Dr. Carl Weggel and Dr. Robert Weggel.
Yes. Kronos's technology is anchored in a granted U.S. patent co-invented with veteran high-field-magnet engineers, its full conceptual design is published on arXiv and prepared for peer review, and its complete simulation dataset is openly available on Zenodo. The company invites anyone to evaluate it on the published mathematics and engineering.
In 2022 — about four months into the company's public launch, and before any technical review — the Fusion Industry Association publicly questioned whether Kronos was a "legitimate fusion company." Kronos chose not to respond rhetorically; instead it published its full design, deposited its complete dataset, and submitted its work for peer review. It welcomes the FIA and anyone else to evaluate the company on its merits.
Kronos is led by founder and executive board member Priyanca Ford (publishing as P. I. Ford), with co-inventors Dr. Carl Weggel and Dr. Robert Weggel — magnet engineers with backgrounds at MIT and Commonwealth Fusion Systems — and a multidisciplinary team of scientists and engineers.
Kronos has completed and openly published a full conceptual design and its supporting simulation-validation package. It is a design- and simulation-stage program advancing toward hardware — and it states that plainly rather than overselling its maturity.
The design targets a projected NOAK (nth-of-a-kind) required power-purchase-agreement price of $56–92/MWh — positioned within the firm, carbon-free power market's clearing band.
Commercial electricity grids (MetroVolt), defense applications (AEGIS), and the growing demand for firm, carbon-free power from industrial users and AI data centers.
Three ways: a compact, low-neutron D–³He design with direct energy conversion (rather than a neutron-heavy D–T steam cycle); an independent, research-first funding model with no venture capital; and full public transparency — the entire conceptual design and validation dataset are open for anyone to check.
Kronos is privately and family-funded. It does not rely on venture capital or government grants, which lets it anchor milestones in physics and engineering rather than funding-cycle optics.
Kronos welcomes technical evaluation, partnership, and briefing requests. Review the open arXiv series and Zenodo dataset, and contact the company at investor@kfe-inc.com.
Priyanca Ford is the founder and an executive board member of Kronos Fusion Energy. A three-time founder with two prior exits, she came to fusion through large-scale energy-systems work at Edison International and leads Kronos's simulation-first engineering program.
