Dutch-led consortium develops calculation model for industrial heat storage

Ben Welter - Friday, December 16, 2016

LOCOSTO PCM test tankA consortium led by the Energy Research Center of the Netherlands (ECN) has developed a calculation model to predict the performance of a phase change material buffer for industrial heat storage in the 100-250° C temperature range. The model is used to optimize the design of a heat exchanger to achieve the required performance in the most cost-effective way. According to the ECN:

"A test installation with around 100 liters of PCM (see photo) is used to measure the performance of the storage and compare it with the model calculations. There is a high level of consistency between the experimental and model outcomes, providing a basis for the further development and scaling of PCM heat storage technology."

The consortium continues to work on the selection of PCMs with the desired attributes for industrial heat storage. 

"We consider salt hydrates as most feasible option for industrial heat storage," said Robert de Boer, thermal systems project manager at ECN. "I wouldn’t say it is ideal, but the best we can get at this moment."

Members of the LOCOSTO consortium are end-users DOW, Perstorp and EMMTEC; system suppliers IEE and Bronswerk Heat Transfer; materials suppliers PCM Technology and Nedmag; and Dutch research institutes TNO and ECN. "LOCOSTO" stands for "LOw COst STOrage" of heat.
