Is zeolite suitable for sorption heat storage?

The experimental characterization of a commercially-available zeolite for sorption heat storage has been carried out and reported. The considered zeolite, 13X type, has been chosen for its suitability to long-term thermal energy storage even after multiple hydration/dehydration cycles.

How can zeolite be regenerated?

The regeneration of zeolite can be realized by the introduction of waste heat and solar energy, which makes it an energy-saving choice when considering energy storage and heat transfer.

What is zeolitic energy storage?

In contrast to established heat storage systems based on water, zeolitic systems reach energy densities of 150–200 kWh m −3 and allow for seasonal storage with almost no heat loss. However, a commercial breakthrough was not yet successful.

How zeolite can be used for energy transfer?

The storage property of zeolite makes the ESS able to realize long-term and short-term energy transfer.

Zeolite composite with high energy density was found suitable for the ESS.

Why do zeolite heat storage systems have higher convective heat transfer?

This is due to the higher vessel inlet temperature of 40 °C and later 100 °C and, consequently, a higher convective heat transfer to the vessel in comparison to a vessel inlet temperature of 25 °C (Fig. 5). The present study aims to experimentally investigate appropriate operation parameters for a zeolite heat storage system in a laboratory plant.
