Predicted ramp-up and consequences<br />
Page 2<br />
key statements<br />
The planned extension<br />
of wind and solar will<br />
require stabilizing<br />
measures on the grid<br />
level<br />
Most reasonable<br />
measure for new<br />
ínstallations of<br />
renewables is grid<br />
extension. However,<br />
realization cannot follow<br />
the demand<br />
As (retarded) grid<br />
extension will not be<br />
sufficient, energy<br />
storage in the TWhrange<br />
will be required.<br />

key statements:<br />
Siemens is solution provider for<br />
the energy market. <strong>Energy</strong><br />
storage is considered as key<br />
issue.<br />
Siemens expertise in electrochemical<br />
energy conversion<br />
ranges back to early 1960s<br />
Siemens established in Oct<br />
2010 the business unit<br />
`Hydrogen Electrolyzer´<br />

key statements:<br />
Battery storage applications<br />
are limited in the hour range<br />
<strong>Energy</strong> storage >100 MW can<br />
only be addressed by<br />
Pumped Hydro, Compressed<br />
Air (CAES) and Hydrogen<br />
The potential to extend<br />
pumped hydro capacities is<br />
very limited<br />
CAES has limitations in<br />
operational flexibility and<br />
capacity<br />

100 kW Demonstrator<br />
Page 8<br />
key statements:<br />
rated power of the system is<br />
100 kW, peak power 300 kW<br />
(electrical stack input)<br />
H 2 and O 2 are produced at an<br />
outlet pressure of 50 bar<br />
The container is an „selfsustaining“<br />
system. Power<br />
supply as well as water<br />
purification are onboard<br />
a 100 kW-demonstrator will<br />
be delivered 2012 to RWE in<br />
the context of the BMBFfunded<br />
project CO2RRECT*<br />
*CO2-Reaction using Regenerative<br />

key statements:<br />
<strong>Energy</strong> storage is key for a sustainable and CO2- minimized energy scenario<br />
Hydrogen is the option to store energy<br />
quantities > 10 GWh<br />
PEM electrolyzers are very robust and extremely<br />
dynamic. They can be used as load for control power<br />
Siemens is addressing the demand in energy, industry<br />
and mobility by developing high capacity PEMelectrolyzers<br />
There will be a strong convergence between industry<br />
and energy related applications<br />
The energy market place needs to quickly develop<br />
business models to define economics for storage<br />
