A combined heat transfer and exergy analysis is developed and used to quantify the performance of a latent heat thermal energy storage system (LHTES) for solar power generation taking into account two practical constraints. First, for long-term operation the thermal energy stored must equal the...

A Phase Change Slurry (PCS) is a latent heat storage and transfer medium consisting of a Phase Change Material (PCM) as a dispersed phase and a carrier fluid as a continuous phase. PCSs have a high energy density because they use not only the sensible heat capacity of the carrier fluid, but also...

PCM (phase change material) is one of the most popular media in TES (thermal energy storage) system for its high energy storage density and suitable melting temperature. However, its low heat transfer performance leads to low rate of heat stored and released. In this paper, a highly thermal...

We simulate Finnish future energy system with large amounts of CHP (combined heat and power) and wind power. The Nordic countries have ambitious wind power targets, which means a substantial need for balancing power. One third of electricity in Finland is produced by CHP, and a large amount of...
