Researchers at the University of Twente, together with a European consortium, have received a grant of €2.5 million from the Horizon Europe program. The project, called STOREDGE, focuses on the development and validation of an advanced technology for thermochemical heat storage and upgrading.
Storing heat in chemical compounds
This technology stores heat in chemical compounds. The system adjusts the water vapor pressure to determine the temperature at which the heat is released. This allows the heat to be used at exactly the right moment and the right temperature.
Long-term storage
The project aims to develop a system that can store heat for long periods without significant losses, so that this heat remains available for use over periods of days, months, or even seasons.
Conversion to higher temperatures
The stored heat can also be converted to significantly higher temperatures than those at which it was originally captured. This makes it possible to power industrial processes or energy generation that operate at high temperatures.
Widely applicable
The strength of STOREDGE lies in a number of important advantages. For example, the system is widely applicable to a variety of heat sources, such as industrial residual heat and solar collectors; it offers a long service life combined with low operating costs; and it is safe and sustainable, with no negative impact on the environment or health.
Nine partners from across Europe
The consortium consists of nine partners from different parts of Europe, including three universities, a research center, two SMEs, two large industrial partners, and one NGO. The first demonstrations of the technology will take place on a laboratory scale, with a heat capacity of 5 kW.
