    Abstract : Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. READ MORE

    Abstract : Climate change is no longer imminent but eminent. To combat climate change, effective, efficient and smart energy use is imperative. Thermal energy storage (TES) with phase change materials (PCMs) is one attractive choice to realize this. READ MORE

  5. 5. Integrating Latent Heat Storage into Residential Heating Systems : A study from material and component characterization to system analysis

    Author : Tianhao Xu; Samer Sawalha; Björn Palm; Justin NingWei Chiu; Tianshu GE; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase change material; thermal energy storage; heat pump; load shifting; space heating; Energiteknik; Energy Technology;

    Abstract : Latent heat thermal energy storage (LHTES) systems can be coupled with heat pump (HP) systems to realize heat load shifting on demand side. With phase change material (PCM), well designed LHTES components exhibit high storage energy density and thus have large potentials to be integrated in residence where a compact energy storage solution is needed.
