The technologies that could transform energy and transportation are here, and they're worth watching. This year’s list from MIT Technology Review highlights some fascinating developments, from China’s renewable giants to innovative battery tech and new ways to power data centers.

China’s renewable powerhouse, Envision Energy, is expanding beyond its domestic market with projects in Europe and Australia. Meanwhile, WeLion New Energy is pushing the boundaries of battery research, achieving unprecedented energy densities.

Data centers are hungry for reliable power, and Fervo Energy and X-energy are stepping up with next-gen geothermal and small modular nuclear reactors. The energy storage market is booming, with Form Energy’s iron-air batteries and Energy Dome’s compressed CO2 storage solutions leading the charge.

This year may not have been all sunshine and rainbows, but the technologies and companies on this list offer hope for a more sustainable future.
