To overcome the temporal imbalance between supply and demand of thermal energy, scientists at TU Wien have developed a flexible, modular and scalable heat storage system. The combination of microfluidics (lab-on-a-chip technology) with reversible solid-gas reactions allows for thermochemical energy storage for a wide range of  applications.

The microfluidic approach forms the basis for an extremely compact system that can easily be adapted to existing infrastructure. Due to its modular design the system can be scaled to the respective requirements, e.g. for industrial waste heat recovery or for solar power plants.
