Thermal batteries could be the next big thing in energy storage, and companies like Rondo Energy and Antora Energy are betting big on them. Instead of using materials like lithium, these systems store excess electricity as heat in things like bricks or graphite, reaching over 3,000°F. That heat can then power factories or even be converted back into electricity. Rondo, backed by investors like Bill Gates, is scaling quickly, aiming to produce enough thermal batteries by 2027 to cut 12 million tons of CO₂ emissions. While challenges like production growth and market adoption remain, thermal batteries could play a critical role in decarbonizing industrial manufacturing for products like steel and cement.
