TerraPower Eyes AI Data Centers with Molten-Salt Storage
TerraPower, the Bill Gates–founded nuclear startup, is preparing to announce its first data center project this year, Bloomberg reported. The company is building a 345-megawatt molten salt–cooled Natrium reactor (its first plant is under construction in Wyoming) and says the design includes a large molten sodium thermal storage reservoir. Instead of throttling reactor output, TerraPower plans to store excess heat and release it to meet fast, variable data-center loads, enabling rapid power ramping while keeping the reactor at steady output. The approach is intended to pair nuclear’s high capacity factor with storage flexibility for renewable-heavy grids and AI workloads.
A novel nuclear-plus-thermal-storage approach could influence how AI data centers and cloud infrastructure secure reliable, flexible power — relevant to AI/ML infrastructure planning and energy strategies for high-demand computing.

Investing in Energy Tech: The Smart Move for AI Boom
A Sightline Climate report warns that power constraints are slowing data center builds, creating investment opportunities in energy technologies. Of 190 gigawatts of planned data center capacity tracked, only 5 GW are under construction and about 6 GW came online last year; roughly 36% of projects slipped timelines in 2025 and up to 50% of announced projects may be delayed. The shortfall in generation and grid capacity is driving large tech companies (Google, Meta, Amazon, Oracle) to invest in solar, wind, nuclear and long‑duration batteries such as Form Energy’s 100‑hour product. Startups focused on power conversion and grid/software management (Amperesand, DG Matrix, Heron Power, Camus, GridBeyond, Texture) are gaining investor attention. Goldman Sachs projects AI will raise data center power consumption ~175% by 2030, while the EIA expects U.S. battery storage capacity to approach 65 GW this year.
Behind-the-Meter Power Challenges for Datacenters
SemiAnalysis reports that behind-the-meter (BTM) power generation for AI datacenters has become mainstream, with 75GW of firm orders tracked, 20GW ordered in Q2 2026 alone. Major deals include Microsoft's 5GW with Chevron and Crusoe, Google's 930MW aeroderivative turbines and 900MW Bloom fuel cells, and OpenAI's 1.4GW campus with Jenbacher engines. The report details six key challenges: contracts & bankability, permitting, fuel supply, equipment procurement, workforce, and electrical physics. It highlights permitting delays (e.g., Oracle's Project Jupiter) and the rise of Energy-as-a-Service vendors like VoltaGrid. The analysis emphasizes the shift towards reciprocating engines and fuel cells, and the growing importance of balance-of-plant equipment.
Race to Power the Grid by 2035 Widens
Tech companies' growing AI compute needs are driving investment and commercial deals across fusion, small modular fission, natural gas, and long-duration battery storage as contenders to supply reliable 24/7 power by 2035. Natural gas remains the current baseload choice but faces supply-chain vulnerabilities and multi-year turbine backlogs. Several small modular reactor (SMR) firms and fusion startups aim to connect commercial plants to grids in the early 2030s; notable projects include Kairos Power's Hermes 2 demo, Oklo's 2028 target, Commonwealth Fusion Systems' demo and 400 MW Arc, and Helion's aggressive plan to deliver electricity to Microsoft by 2028 and to supply OpenAI at multi-gigawatt scale by 2030–2035. Cost and scale remain key hurdles: current levelized costs for new nuclear and fusion are high versus gas and renewables paired with batteries, while new long-duration storage (iron‑air, organic fluid designs) could undercut alternatives.
