Weekly top stories on paths to abundant energy: fusion, advanced fission, next-gen solar, storage, geothermal, and more.
Energy
Executive Summary The week of May 5 - May 12, 2026 was unusually fusion-heavy, but with a substantive twist: the headlines were not net-energy claims, they were the enabling infrastructure that determines whether the next generation of fusion machines actually reaches the grid. Helion unveiled "Tiny Merge," a

Executive Summary This week marks a structural inflection in how the path to abundant energy is being financed, regulated, and physically connected to the grid. The single most consequential development is Commonwealth Fusion Systems' April 28 PJM Interconnection application for its first ARC fusion power plant — christened the Fall
Energy
Executive Summary This week tightens the link between three converging threads in the abundant-energy story: private fusion is consolidating around concrete grid-scale commercial timelines, advanced fission is migrating from regulatory scaffolding to multi-GW commercial commitments, and the storage stack is bifurcating into a sodium-ion mass-market path and a long-duration flow-chemistry
Energy
Executive Summary This week marks a structural transition in the path toward abundant energy: the first pure-play enhanced-geothermal company moved to go public, the UK crystallized a £1.3 billion national fusion commitment, and the first fully high-temperature superconducting (HTS) tokamak crossed a 1,000-second plasma threshold. Taken together, the
Energy
Executive Summary This week crystallized the fusion energy sector's transition from an R&D curiosity to a recognized industrial policy priority, while simultaneously demonstrating that the parallel technologies needed to bridge the gap to fusion -- advanced geothermal, perovskite tandems, and grid-scale storage -- are scaling on
