Zap Energy

Zap Energy is a Seattle, Washington fusion energy company pursuing commercial fusion power via the sheared-flow-stabilized Z-pinch — a compact, magnet-free pulsed-power approach in which a flowing column of deuterium plasma is compressed (pinched) to fusion conditions inside a roughly two-meter metal tube, with shear in the axial flow stabilizing the pinch in place of the heavy superconducting magnets used by tokamak and stellarator designs. Founded in 2017 by Benj Conway, Brian A. Nelson, and Uri Shumlak as a spinout of University of Washington and Lawrence Livermore National Laboratory research, the company has developed a lineage of devices — ZaP, ZaP-HD, FuZE, FuZE-Q, and FuZE-3 — culminating in 2024 with Century, a 100-kW-scale repetitive pulsed-power test platform with liquid-metal walls intended to demonstrate plant-relevant technologies. In November 2025 FuZE-3 reported plasma electron pressures of 830 MPa (1.6 GPa total), the highest pressure measured in any sheared-flow-stabilized Z-pinch and a marker on the path to scientific energy gain (Q>1). Zap Energy was selected for the U.S. Department of Energy's Milestone-Based Fusion Development Program in May 2023 and received DOE approval of the preconceptual design of its Fusion Pilot Plant. The company has raised over $325 million across Series A–D from Breakthrough Energy Ventures, Lowercarbon Capital, Energy Impact Partners, Chevron Technology Ventures, Shell Ventures, DCVC, Valor Equity Partners, and Addition. As of April 2026, Zabrina Johal serves as CEO with Conway as President, and the company has expanded its mandate to also pursue small modular fission alongside its fusion roadmap. Zap Energy has no public developer API, SDK, GitHub organization, or open-source release; the technical surface is published as peer-reviewed papers and DOE milestone reports.

Zap Energy is profiled on the APIs.io network. Tagged areas include Fusion, Fusion Energy, Nuclear Fusion, Z-Pinch, and Sheared-Flow-Stabilized Z-Pinch.

Zap Energy’s developer surface includes product news, YouTube channel, and 10 more developer resources.

scored 2026-09-08 · rubric v0.20.0
Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/zap-energy: open an issue to ask a question, or submit a pull request to add artifacts.
