The International Flow Battery Forum (IFBF®) – the leading event for the flow battery community – is back on 16-18 June 2026 in the capital of Hungary, Budapest, at the Intercontinental Hotel, located in the city centre in front of the Danube river.
The IFBF is the annual event promoting the most recent developments in the science, technology and commercialisation of flow batteries, covering a broad range of interests in the research and commercial aspects of flow batteries.
After the great success of the 2025 edition in Vienna, this year’s edition expects 350 delegates from all over the world – featuring the leading experts of the flow battery sector – along with 20 exhibitor booths and 50 posters. Only a few months ahead of the event, the IFBF2026 exhibition area is already 75% booked.
Over three days, the IFBF agenda will feature talks on flow batteries latest developments and commercialisation,with policy presentations and market forecasts. A number of networking activities are also foreseen, starting with a conference dinner on 16 June at Hungary’s most famous and only Hungaricum restaurant, the almost 130-year-old Gundel Palace.
On 17 June, a speed pitch session will allow researchers to introduce their research in less than a minute, which will set the stage for networking at the evening’s poster session and cocktail reception. Finally, on 18 June, a local site visit will take participants to see a flow battery in action at a Hungarian site in Osku.
The IFBF call for proposals closed at the end of January with over 100 submissions. ”The amount of submissions this year shows the interest and crucial focus flow battery is achieving at the international level’’ states Secretary Anthony Price, Programme Coordinator of the IFBF2026. ”We still have space for some poster proposals, and we are always interested in reading about outstanding presentations that could engage the flow battery experts in the audience. If that’s your case, contact us!”
Sessions at the IFBF this year will include, but are not limited to, large scale flow battery systems for transmission reinforcement and data-centres, as well as distributed energy storage systems. The flow battery industry will also be discussed, along with the technology issues of the sector, the strategy and the comparison with other energy storage systems. The preliminary programme will be ready at the beginning of March. Tickets sales will follow soon.
IFBF2026 is possible thanks to the sponsoring of Quino Energy, Rongke Power, AMG Titanium, H2, InoHub Energy, and Volterion. The International Flow Battery Forum 2026 is supported by Flow Batteries Europe (FBE) and organised by CLERENS.
