The International Flow Battery Forum will take place from 24 to 26 June in Vienna, Austria, at the Intercontinental Hotel, supported by CellCube and Flow Batteries Europe! 

Over three days, the conference will feature talks, panel sessions, open discussions, networking breaks, a poster session, a conference dinner and a local site visit.

The International Flow Battery Forum (IFBF®) is the leading event for the flow battery community. The IFBF promotes the most recent developments in the science, technology and commercialisation of flow batteries. Our conferences cover a broad range of interests in the research and commercial aspects of flow batteries.

This year, we return to Vienna since our first edition in 2010, and we will be hosted by Cellcube. Christoph Stelzer, their COO will welcome us and introduce Cellcube’s flow battery strategy.

 

We are very pleased to announce that Commissioner David Hochshild, Chair of the California Energy Commission, has accepted our invitation to address the IFBF this year. He will be explaining the background to California’s Long Duration Energy Storage initiative and the need to have diversity in energy storage systems, with 6 different non-lithium long duration technologies under development and demonstration. Under the CEC’s guidance, California has one of the boldest programmes in the world for supporting new energy technologies. 

We also have a keynote address from Viktor Horváth, Deputy State Secretary for the Energy Transition of Hungary, on the topic of diverse energy storage technologies for the energy transition.

 

Users and operators of storage including Verbund, Energie Burgenland, EDF and EDP Renewables will talk on the role of flow batteries and energy storage in their operations, and we will also hear from Rongke Power on the challenges and operational performance of their multi 100 MWh flow batteries in China. Going back to Europe, Flexbase, will expand on their plans for a 100 MW plus flow battery in Switzerland.

 

But energy storage is also diverse and can be distributed, so we will also include smaller scale installations, and a range of technology types. With our eyes on the skies, we will close with a report on flow batteries in space by Fraunhofer UMSICHT, and the news of a programme funded by the German Space Agency.

 

The IFBF 2025 will take place at the Intercontinental Hotel Vienna, a five-star Hotel in the city's heart! We have secured a special rate for IFBF attendees. Book your room in advance using this link: Reserve Your Stay.
