Ignova recovers low-grade waste heat, often lost from factories, solar thermal panels, and data centres, and repurposes it for clean cooling and thermal storage. The system uses newly developed ultra-porous materials, similar to molecular sponges, that absorb and release water vapour at low temperatures. It enables cooling without compressors or refrigerants, using up to 90% less electricity than traditional systems. Designed for easy retrofitting, Ignova extends the value of wasted heat, supporting climate goals and boosting energy resilience
