Technology Assessment & Commercial Milestones

Achieved first plasma in HH70 in mid-2024 — the world's first all-HTS tokamak to operate, narrowly preceding CFS SPARC. Now scaling to HH170 with a 1 GWe pilot on the same compact-high-field architecture as CFS. Thesis: China's HTS, vacuum and superconductor supply chain plus Shanghai capital can match CFS on timeline at lower capex. Key engineering bottlenecks: Domestic REBCO tape quality; Tritium fuel cycle integration. Recent milestones: Jun 2024 — HH70 first plasma; 2025 — Series B reportedly oversubscribed. Device pipeline: HH70 → HH170 demo. Timeline: Demo by 2027; commercial by 2035.
Technical & Economic Profile

HH70 first plasma mid-2024. HH170 demo by 2027; commercial plant 2035.

Peer positioning · Energy Singularity

China's CFS analog. Achieved HH70 first plasma in mid-2024 — ahead of SPARC's schedule — with deep sovereign HTS supply-chain momentum.

Physics basis

Targets nTτE ≳ 3×10²¹ keV·s·m⁻³ at T ≈ 10–20 keV — the D-T breakeven envelope. REBCO-enabled compact tokamaks operate at 20 K and reach > 20 T toroidal fields, replicating ITER-class confinement at ~1/40th the volume. Spherical variants drop aspect ratio to A ≈ 2.0 to maximise plasma β at lower absolute fields.

Engineering bottlenecks
  • 14.1 MeV neutron flux degrades RAFM steel and tungsten armor above ~80 dpa, forcing periodic first-wall replacement.
  • Achieving a Tritium Breeding Ratio > 1.0 in compact geometry — especially on space-constrained spherical-tokamak center-posts — is unresolved.
  • REBCO tape suffers irreversible critical-current loss above 0.4% tensile strain; > 30 T fields generate GPa-class Lorentz forces requiring MP35N superalloy substrates and carbon-fiber cocoons.
  • Sudden plasma disruptions vaporise plasma-facing components — repair downtime is the single dominant LCOE variable per ARPA-E pyFECONs.
LCOE drivers
  • Disruption-driven capacity-factor losses (AI digital-twin control projected to cut NOAK LCOE 17–20%).
  • ⁶Li enrichment supply chain: ~100 t per plant at $5,000/kg can hit 80% of overnight capital cost.
  • Balance-of-plant (steam turbine, heat exchangers, cooling towers) dominates D-T capex.
Class-level competitive analysis

CFS and Energy Singularity are in a direct capital-and-engineering race to validate the compact HTS tokamak concept; CFS leads on global funding, Energy Singularity on localised supply-chain momentum. Kronos and ENN diverge sharply by pursuing spherical geometry to enable high-β aneutronic cycles that delete the steam plant entirely — accepting harder physics in exchange for a streamlined balance-of-plant.

Founding Team & Academic Backgrounds

Who built Energy Singularity

Full founding team page

Energy Singularity has established itself as a fast-moving, highly capitalized force within China's rapidly growing private fusion sector. The founding team, led by brilliant plasma physicists Dr. Guo Houyang and Dr. Yang Zhao, joined forces with HTS engineering specialists Ye Yuming, Dong Ge, and Li Zhuyong. Their extraordinary synergy of advanced magnet engineering and computational plasma physics allowed them to design, build, and operate the "Honghuang 70"—the world's very first all-HTS spherical tokamak—in less than two years, showcasing an unprecedented speed of hardware execution.
