A research team has successfully demonstrated a new method for storing solar energy for extended periods. The technology, based on a novel molecular system, can capture energy from sunlight and release it as heat on demand, potentially revolutionizing how we power homes and industries.

The core innovation involves a specially engineered molecule that changes shape when exposed to sunlight. This shape change stores energy, which is then locked in place until a specific chemical trigger is applied. When triggered, the molecule reverts to its original shape, releasing the stored energy as heat. This process can be repeated thousands of times without significant degradation.

Initial applications are expected in off-grid power systems and for providing industrial process heat. The developers state that a commercially viable product could be available within the next five to seven years, pending further large-scale testing and regulatory approvals.
