Integrated solutions of thermal energy storage for building applications

 

Specific challenge:Storage plays a pivotal role in synchronising energy demand and supply, both on a short and long term (seasonal) basis. Transformation of our existing building stock towards very low energy buildings and nearly zero energy and Plus-energy buildings requires effective integration and full use of the potential yield of renewable energy.  Thermal storage is a key priority to make such a step, particularly considering the energy renovation of the existing stock, where compact building level solutions are required.

Scope:Proposals should address advanced solutions required to reduce thermal losses, reduce pressure drops, and improve heat exchange in and between storage material and heat carrier. Having in mind a system approach, innovations are required at different levels. High energy density storage materials are needed in terms of long term multi-cyclic stability at tuneable temperature levels. These advanced energy storage materials should allow regeneration temperatu
