MIT has released its list of top 10 climate tech companies to watch in 2026. The annual list highlights firms with real-world impact.

Energy Dome made the cut for its carbon dioxide batteries. The Italian firm stores energy using compressed CO2.

Fervo Energy was picked for geothermal power. It uses drilling tech from the oil industry to tap underground heat.

WeLion and WaveSave also feature on the list. They work on batteries and wave energy.

The list is closely watched by investors. Past picks have gone on to raise large funding rounds.

MIT says the winners were chosen for scale potential. Lab ideas alone did not make the cut.

Climate tech funding has slowed this year. The list aims to spotlight firms that can survive the downturn.

The list began five years ago. Alumni founders feature heavily this year. MIT says impact mattered more than novelty.

Investors use the list to spot trends. Several past picks are now valued above a billion dollars.
