Separation of

Energy (kWh) – electrolytes

Power (kW) – cell stacks

“Inert” electrodes – no stress buildup or structural degradation in electrodes

Extended electrode durability/reliability

Long cycle life, independent of SOC/DOD

Passive heat management – flowing electrolytes carry away heat generated; large volumes of electrolytes act as heat sinks

Effective stop of reactions by pump turn-off – no thermal runaways – safe and low self-discharge

Stores up to MWh’s/MW’s of electricity, with durations from mins up to hrs and even days

• Located at Wind Park in Braderup close to Flensburg

• With 320kW peak power and 1MWh capacity one of the largest flow batteries in

Europe

• Customer: Energiespeicher Nord GmbH, a joint venture of Bosch and

„Bürgerwindpark Braderup-Tinningstedt“

• Main applications:

• Participation in the frequency control market

• use of the stored energy for the self consumption of the wind park

• energy trading

• grid stabilization


Roadmap of performance improvement and cost reduction

13

• Continuous scale up of battery stack size

• Containerized design for fast and cost effective production and installation

• In house development of key components (electrolyte, membranes,…)

• Leverage advantages of substantially improved electrolyte

• Performance improvements: Get more power and energy out of the same

system by optimizing the design

• Leverage economies of scale for material purchase and manufacturing process


Scale up of stack power rating
