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
temperature and pressure ranges of about 500-
600°C and 10-60 bars 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 (illustrated in the figure below), here
the heat exchanger for enrichment of the lye is in
focus of the development.
