How thermal batteries could replace lithium-ion batteries
Thermal batteries could be the future of energy storage, offering a cost-effective way to store renewable energy and decarbonize heavy industries like steel and cement production. Unlike lithium-ion batteries, they use raw materials like bricks and graphite to store heat, making them cheaper and more scalable. CNBC talked to companies like Rondo Energy and Antora Energy to understand why they’re betting big on this technology and how it could transform clean energy.
