Phase Change Materials:
- release thermal heat at a nearly constant temperature near the specific material’s phase change temperature.
- have a high energy storage density within a limited operational temperature range, compared to traditional water buffers. This makes PCMs a compact storage option that can reduce the buffer volume by a factor 2 to 3.
- allows for the efficient storage and optimal usage of thermal energy from intermittent (renewable) sources on a daily time scale.
- reduce energy losses. They are very suitable for daily usage as well as on longer time scales.
- can deliver high peak power outputs.
- are commercially available in a large variety, giving access to a vast range of phase transition temperatures with applications for both heating and cooling purposes (s.a. floor heating or domestic hot water)
- offer different size scale possibilities, ranging from compact solutions to very large storage units.
EnergyVille offers fully-equipped test facilities, up to temperatures of 90 °C (domestic and tertiary applications) and an experienced team of experts.
The daily mismatch between heat demand on a domestic level and supply from renewable sources (such as solar collectors, PV coupled heat pumps and heat from micro-CHP units) implies the need for efficient and compact storage methods of thermal energy. PCMs offer a compact solution, as compared to the more conventional water storage tanks that store perceptible heat.
PCM heating & cooling can be applied for all storage purposes, but its compact size offers advantages especially to integrated and/or transportable energy storage.
- Manufacturers of thermal energy buffers and solar boilers aiming at the incorporation of PCMs in their energy systems.
- Producers of heat pumps considering compact storage units for heating and/or cooling purposes.
- Mobile & transportable storage units, like truck-mounted containers.
