Integrating cogeneration and thermal energy storage for an energy-efficient industrial batch process
Integration of an adsorption thermal energy storage unit into a brewery heat supply system in combination with a gas-motor cogeneration unit was designed and analyzed. The feasibility of the designed system was demonstrated by building and testing a first prototype of the storage in lab-scale yielding sufficient storage density.
The demonstrated concept of continuously operated cogeneration units combined with adsorption thermal storage is generally applicable to discontinuous heat demands of industrial batch processes. Hereby, adsorption thermal energy storage also offers the option to link low temperature heat sources to higher temperature industrial processes. Furthermore, adsorption thermal energy storage allows for flexible storage time and low heat losses, if the adsorption pair is isolated from each other during storage. Thus, adsorption thermal energy storage provides large flexibility in operation and design to match heat requirements of batch processes and hence to enhance energy efficiency in industry.
