Redox Flow technology with focus on high-power and high-cycle applications
Flow batteries have, among other advantages, the benefit to independently scale power and capacity. This often leads to very long discharge times for flow batteries because the cost per kWh is reduced as only the cost of more electrolyte for increased battery capacity needs to be taken into account. The cost per installed kWh is an often-used comparative value. In applications this leads to business cases which have small to medium cycles per year (1—2 cycles per day) because long discharge times also lead to long charge times and one can not exceed the 24 hours of one day. The energy stored must have a high value and the cost of the battery system needs to be as low as possible to make a reasonable return on investment. This presentation focuses on applications with very short discharge times of only several minutes to half an hour using the unique high cycle stability of vanadium flow batteries. Depending on the application a battery with 30 min discharge time can perform up to 24 full cycles
Dr. Thorsten Seipp is Co-Founder and CTO at Volterion GmbH. After studying chemical engineering at TU Dortmund he started research on flow-batteries at Fraunhofer UMSICHT and did his phD on flow battery cell developments at University-Duisburg Essen. With colleagues from Fraunhofer he founded Volterion in 2015. Volterion has now more than 18 employees selling flow battery components for B2B customers.
