Product description

Advanced Adiabatic Compressed Air Storage (AA-CAES): Plants based on AA-CAES use electricity during periods of excess power generation to compress air. The heat contained in the compressed air is stored in a Thermal Energy Storage, and the high pressure cooled air is stored confined in a hermetically sealed reservoir. To generate electricity during periods of high demand, the air is released from the reservoir, heated from the storage, and is expanded through a turbine-generator setup. The efficiency of a well designed AA-CAES plant is projected to reach about 75 % (close to the efficiency of pumped hydro storage). The heat storage concept for AA-CAES with temperatures and pressure ranges of about 10-60 bars and 500-600°C are being considered using a combination of encapsulated phase-change materials (PCM) with a packed bed of rocks.

High-temperature process heat: The storage of thermal energy at temperatures above 400°C is of interest to process-industry applications such as glass recycling, cement production, and metallurgical processing. Accordingly, research is focused on latent and sensible heat storage for these temperature ranges to provide solutions for economic and compact storage of fluctuating sources of high-temperature heat and/or electricity.

Building Applications - space heating, hot water generation: The heating and cooling demands of buildings necessitate storage of thermal energy for winter and summer. Sensible, latent, and sorption storage technologies can be used to bridge the time shift between the availability of energy and user demand. The application temperature range for heating, ventilation, and air conditioning in buildings will be covered by these storage technologies in the temperature range of about -10°C to 250°C. One example for residential space and water heating, the dilution energy of concentrated lye is investigated (see figure), here the heat exchanger for enrichment of the lye is in focus of the development.
