Three climate technologies breaking through in 2026

Three climate technologies are making breakthroughs in 2026, according to MIT Technology Review. Sodium-ion batteries are emerging as an alternative to lithium-ion batteries due to sodium's abundance and lower fire risk. Next-generation nuclear reactors are being developed to generate electricity more efficiently and safely. Hyperscale data centers, while not directly climate technologies, are driving electricity demand and becoming a key part of global infrastructure, especially in relation to AI development. These technologies reflect the current focus on sustainable energy solutions amidst the climate crisis.
