Pit Thermal Energy Storage systems
A Pit Thermal Energy Storage (PTES) allows for district heating plants and utility companies to collect and utilize excess energy and heat that would otherwise go to waste. By utilizing the excess heat, the energy utilization is optimized significantly, while the system-flexibility is likewise improved.
PTES is a commercially proven thermal energy storage technology, which is both scalable and cheap compared to other Power-to-X (PTX) alternatives on the market.
