Heat batteries: A solution to decarbonize industrial heat

Industrial production heavily relies on fossil fuels, making it a major contributor to carbon emissions. The need to decarbonize industrial heat is crucial to combat climate change. Electrification, using wind and solar power, is a cost-effective and scalable alternative to traditional heat sources. Analysts predict that electrified industrial heat could be a trillion-dollar market. However, the intermittent nature of wind and solar poses a challenge for continuous heat supply. To overcome this, teams are developing industrial heat batteries that store heat using materials like liquid salts, liquid metals, and solid carbon. By heating brick using radiation and combining it with iron wire, a simple and low-cost heat battery can be created. This concept has the potential to revolutionize industries by providing clean heat consistently.
