MIT Technology Review announces 2026 notable climate tech companies

MIT Technology Review has announced its 2026 list of notable climate tech companies, highlighting innovations aimed at reducing greenhouse gas emissions and mitigating climate-related disasters. The selection process emphasized research achievements, funding, and implementation track records across various industries and stages of development.

A significant trend in this year's list is the focus on energy storage, driven by the rising electricity demand from AI data centers. Key companies identified include Energy Dome, which uses compressed carbon dioxide for long-duration storage; Moment Energy, a Canadian firm repurposing EV batteries for grid-scale use; and Form Energy, which produces iron-based batteries capable of storing energy for several days.

The report notes a shift in the global landscape, observing that the United States is no longer the sole leader in climate tech due to changes in federal regulations and incentives. Consequently, many selected companies are based outside the U.S., with China emerging as a major hub for innovation. Notable Chinese entries include WeLion, which develops semi-solid batteries for electric vehicles, and Envision Energy, which operates large-scale wind power and energy storage projects.
