6 FAQs about [Zeolite energy storage density]

What is zeolite heat storage?

In the last years, an increasing interest in zeolite heat storages and appropriate zeolitic materials (e.g., 4, 5) could be recognized. Zeolite heat storages are chemical storages that promise to reach energy densities of 150–200 kWh m −3 and almost lossless seasonal heat storage 6.

Are zeolite-based heat storage processes based on binderless zeolites?

Binderless zeolites are able to adsorb a higher amount of water and consequently lead to a higher energy storage density than heat storages using zeolites with binder. Therefore, it is the aim of the presented work to develop a simulation model for zeolite-based heat storage processes using special binderless zeolites of type NaY.

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.

Are zeolite-based heat storage a time and space dependent model?

The work can be concluded as follows: A time and space dependent simulation model of an adsorptive, zeolite-based heat storage with binderless zeolites of type NaY could be developed. It succeeded to adapt the model to the experimental results of a laboratory plant, satisfactorily.
