Thermochemical heat storage in salt hydrates is a promising method to improve the solar fraction in the built environment. The major concern at this stage is liquefaction followed by washing out of active material and agglomeration into large chunks of salt, thus deteriorating the diffusive properties of the porous salt hydrate structure. In...

A 140 l lab scale shell-and-tube PCM heat storage was built and tested, and the experimental results were compared to a numerical model. Natural convection in the PCM was found to significantly influence the local temperature distribution in the storage vessel, which could not be predicted well by the model, since the model assumes only...

Sailing Heat is a concept for transportation of industrial waste heat over waterways by means of push barges to a heat consumer. This concept is studied for the Netherlands where transport by ship is attractive thanks to the many canals and industries located near waterways. The sailing heat concept offers higher flexibility compared to fixed...

A 140 liter lab scale shell-and-tube PCM heat storage was built and tested, and the experimental results were compared to a numerical model. Natural convection in the PCM was found to significantly influence the temperature distribution in the storage vessel. A horizontal orientation was found to be beneficial due to increased heat exchange...

To reach high solar fractions for solar thermal energy in the built environment, long-term heat storage is required to overcome the seasonal mismatch. A promising method for long term heat storage is to use thermochemical materials, TCMs. In this research, a lab-scale test thermochemical heat storage system is tested experimentally and modeled...

Recently, there has been a lot of interest in PV thermal systems, which generate both heat and power. Within the WenSDak project, several companies and research institutes work together to (further) develop several uncovered PVT collectors. The outdoor performance of prototypes of these collectors is being evaluated in an outdoor test setup. The...

The increasing share of renewable energy in the energy supply system requires a more balanced equilibrium between energy supply and demand. Research and development activities in the area of smart electricity grids is already a very visible result of that. The balancing of heat supply and demand is of equal importance when the use of solar heat...

An interesting thermochemical material for compact seasonal heat storage is magnesium sulfate heptahydrate MgSO4•7H2O. Previous studies in the field showed that this material presents a storage energy density of 1 GJ/m3 when the material is built in a TC storage system with a 50% porosity packed bed reactor. However, the material has slow...
