Fusion and advanced nuclear intelligence
Fusion energy startups, advanced fission reactors, and next-generation nuclear technology.
Fusion energy and advanced nuclear fission represent the frontier of clean baseload power generation. Private investment in fusion has surpassed $7 billion cumulatively, with over 40 fusion companies now pursuing various confinement approaches — magnetic (tokamak, stellarator), inertial (laser), and alternative concepts (field-reversed configuration, Z-pinch, magnetized target). Commonwealth Fusion Systems, TAE Technologies, Helion Energy, General Fusion, and Zap Energy are among the most-funded ventures, with several targeting first-plasma or prototype demonstrations before 2030.
Advanced fission — including Generation IV reactor designs and small modular reactors (SMRs) — is closer to commercial deployment. NuScale Power received the first SMR design certification from the US Nuclear Regulatory Commission. Kairos Power, X-energy, TerraPower, and others are progressing through licensing and construction phases. In China, the HTR-PM high-temperature gas-cooled reactor achieved commercial operation in 2023. These reactors offer potential advantages in safety, waste reduction, factory fabrication, siting flexibility, and process heat for industrial applications including hydrogen production.
Both fusion and advanced nuclear are attracting intense interest from data center operators and technology companies seeking firm, 24/7 clean energy. Microsoft, Google, Amazon, and others have signed power purchase agreements or invested directly in advanced nuclear and fusion companies. The connection to the hydrogen economy is significant: high-temperature nuclear reactors can provide both electricity and process heat for SOEC electrolysis, potentially achieving the lowest green hydrogen production costs.
Delphidata tracks fusion companies and their technology approaches, advanced fission reactor developers, demonstration project timelines, regulatory licensing progress, private and public funding, corporate PPA commitments, and the competitive dynamics shaping which technologies will reach commercial scale.

Fusion companies and programs
Fusion energy startups and national programs — mapped with confinement approach, plasma performance milestones, funding raised, demonstration project timelines, key technical targets (net energy gain, power plant design), and team/partnership composition.
Advanced fission reactors
SMRs and Generation IV reactor designs — NuScale, X-energy, Kairos Power, TerraPower, GE-Hitachi BWRX-300, Rolls-Royce SMR, and others. Tracked with reactor type, thermal/electrical output, licensing status, reference plant orders, and construction timelines.
Regulatory milestones
Design certification applications, construction permits, operating licenses, and regulatory framework development across the US NRC, Canadian CNSC, UK ONR, and other authorities. Tracking the licensing timeline for each reactor design and its progression through regulatory review.
Investment and funding
Private equity and venture capital funding rounds for fusion and advanced nuclear companies. Government grants (ARPA-E, UK STEP program, EU Euratom), DOE loan guarantees, and national nuclear program funding. Connected to the companies and projects each investment supports.
Corporate offtake and partnerships
Power purchase agreements and strategic partnerships between advanced nuclear companies and corporate buyers — particularly technology companies (Microsoft, Google, Amazon), industrial hydrogen producers, and data center operators seeking 24/7 clean energy.
