GILDEMEISTER expands its division of renewable energy

a+f acquires majority stake in Cellstrom

Bielefeld. The GILDEMEISTER subsidiary, a+f GmbH based in Wurzburg, which
specialises in renewable energy, is acquiring a majority holding (50.001%)
in the Austrian company, Cellstrom GmbH, based in Eisenstadt near Vienna.
As part of the transaction, a+f is also acquiring a 5% holding in the
parent company, Younicos AG, Berlin. Through this, a+f is paving the way
for its entry into the promising future market of energy storage; the
Cellstrom large battery is based on vanadium redox flow technology.

Cellstrom GmbH was founded in 2000 and specialises in innovative storage
solutions - especially for solar plants. The powerful, long-lasting and low
maintenance vanadium redox flow battery solves the problem of energy
storage. The large battery achieves constant power supply from solar and
wind installations, even in the dark and when there is no wind. After years
of research, the energy storage system from Cellstrom has reached series
production readiness.

With the joint know-how of the companies - Younicos / Cellstrom as a
specialist of storage and grid for renewable energy sources and
GILDEMEISTER as the innovative technology group full of tradition - the
storage technology business is expected to reach double-digit sales figures
in the millions from 2011 on. In future, customers will be able to use
their electricity independently and flexibly at any time. The use of the
storage system as a solar filling station is also of interest. Using a
large battery, eight electric cars can be 'refueled' up to 80%
simultaneously in less than 10 minutes, or 80 four-person households can be
supplied with electricity for an entire night.

The Cellstrom battery system allows the clean, emission-free and quick
supply of energy at any time. It stands out due to its high safety level,
storage stability and fast reaction time. The redox flow battery is
suitable for the most diverse areas of application:
* for the storage of solar-generated electricity,
* as an emergency power supply, so that sensitive production systems and
machine tools, for example, can continue to run in the event of a power
cut,
* to store electricity from wind power and biogas plants,
* as a stand-alone solution wherever there is no stable electricity grid,
* to supply power to compensate at peak times / heavy demand.

The advantages of the redox flow battery are:
* its long lifetime,
* an unlimited number of cycles of charging and discharging
* a reaction time of less than 100 milliseconds,
* extreme resistance to deep discharge,
* only 1% energy loss per year,
* the output and storage capacity are scaleable independently of each
other,
* low maintenance,
* high environmental soundness.

The vanadium redox flow battery from Cellstrom will be presented by a+f
from 9 to 11 June 2010 at the most important solar trade fair worlwide,
the Intersolar in Munich.

a+f is thus expanding its division of renewable energy sources. The latest
figures for the first quarter will be published by GILDEMEISTER on 4 May
2010 - due to its increasing importance for the first time in a separate
segmental report for solar technology.
