Problem
Heavy industries rely on fossil fuels for high-temperature process heat, contributing significantly to global carbon emissions. Decarbonizing these processes is challenging due to the high costs and reliability requirements of alternative solutions like green hydrogen or direct electrification. Existing solutions often struggle to meet the economic demands of low-margin manufacturing industries.
Solution
Calectra provides a thermal storage technology that converts off-peak renewable electricity into high-temperature process heat, stored in patent-pending bricks. This enables heavy industries to access zero-carbon, low-cost heat up to 1600°C. The stored heat is delivered to retrofitted industrial processes using a high-temperature air stream. Calectra's system is optimized for low-cost, high-temperature heat delivery at a large scale, offering a secure and reliable alternative to fossil fuels. By electrifying industrial heat, Calectra aims to significantly reduce CO2 emissions from the manufacturing of essential materials like cement, steel, glass, and chemicals.
Target Audience
Calectra's primary customers are heavy industry manufacturers in sectors such as cement, steel, glass, and chemicals seeking to decarbonize their high-temperature process heat.
