The annual list highlights firms advancing geothermal power, solid-state batteries, and data center energy supplies.
MIT Technology Review published its 2026 Climate Tech Companies to Watch list, an annual project that highlights firms working on climate and energy technology. The list reflects current market momentum in renewables, grid-scale storage, and power for data centers.
China anchors the list again. Envision Energy, a renewables giant, has installed more than 100 gigawatts of wind power and over 50 gigawatt-hours of battery storage worldwide, and it is expanding into Germany, Brazil, Vietnam, and Australia. WeLion New Energy reported a lab result of 824 watt-hours per kilogram.
Operators building or buying power for AI data centers face tight supply, so firms promising steady, dispatchable generation draw attention. Fervo Energy applies horizontal drilling and hydraulic fracturing to make geothermal practical in more locations, and it raised $2.2 billion in a May IPO. Battery makers are racing toward solid-state cells that improve on lithium-ion safety and range.
Watch for Fervo Energy to build toward a gigawatt of geothermal plants by the end of 2030. WeLion New Energy is working to deploy semi-solid-state batteries, which can reach production faster than fully solid-state designs. Envision Energy and its Chinese peers keep pushing into markets outside China.
What matters
- MIT Technology Review released its 2026 Climate Tech Companies to Watch list this week.
- Envision Energy, Fervo Energy, and WeLion New Energy show where grid and storage investment is heading.
- Fervo Energy plans to operate one gigawatt of geothermal plants by the end of 2030.
Why it matters
