MIT Technology Review Names 10 Breakthrough Technologies of 2026 — Sodium-Ion Batteries, Gene Editing, Nuclear, Space Stations & AI Top the List

MIT Technology Review published its 25th annual 10 Breakthrough Technologies list on January 12, 2026 — a curated selection of the scientific and engineering advances that its editors and reporters believe will drive the most significant progress or change in the year ahead. The list was presented publicly at the SXSW 2026 festival in Austin by Niall Firth, MIT Technology Review’s editorial director. This year’s ten technologies span six distinct domains and collectively signal a shift from laboratory research to large-scale deployment. In energy: sodium-ion batteries — which use sodium, as abundant as salt, rather than lithium — are named as a breakthrough alternative for grid-scale storage and affordable electric vehicles, with Chinese manufacturer CATL committing to mass production by year-end 2026. In biology: DNA base editing is highlighted as a tool for correcting single letters of the genetic code to treat rare genetic disorders; and genetic de-extinction is named for its potential to restore biodiversity by reviving traits from extinct species, raising significant ecological and ethical questions. In computing: AI coding tools are recognised as fundamentally changing how software is written, tested, and deployed; and mechanistic interpretability — the emerging field of understanding how AI models reach their conclusions — is named as essential infrastructure for deploying advanced AI safely. In AI and society: AI companions are identified as tools with both therapeutic potential and significant risk. In nuclear and space: small modular nuclear reactors are named for their potential to provide always-on clean power; and commercial space stations — specifically Vast Space’s Haven-1, planned for launch in May 2026 — are identified as the emerging platform for in-space research and commercial activity. Hyperscale AI data centres — which MIT describes as ‘sizzling hot, power-hungry behemoths’ consuming electricity at city scale — round out the list, recognised for their role as the infrastructure of the intelligence economy.
