The International Flow Battery Forum (IFBF) is the annual conference of the flow battery community, held every year since 2010 in a different country. Its 18th edition takes place on 22–24 June 2027 in Barcelona, Spain. Each edition brings together more than 300 delegates – manufacturers, utilities, suppliers, policymakers, researchers, academics and students – and the papers presented are published in the IFBF Book of Papers, which now holds 821 papers.

The International Flow Battery Forum (IFBF®) is the annual event that promotes the most recent developments in the commercialisation and technological advancements of flow batteries – a sustainable and safe long-duration energy storage technology, ideal for renewable energy storage.

Covering a broad range of interests in the industrial and research aspects of flow batteries, the conference brings together users, manufacturers, suppliers, policymakers, academics, and students from across the globe to raise the profile of flow batteries within the energy storage sector, to showcase the latest scientific and technological achievements, and to discuss their implications for flow battery manufacturers.

IFBF is recognised for its unique combination of high-level technical content and commercial networking, creating a dynamic platform for collaboration across the flow battery community.

With a variety of battery technologies on the market, the IFBF works to make sure that the benefits of flow battery systems are recognised and understood.

Each year, the IFBF takes place in a different country to meet, learn, discuss, and raise the profile of flow batteries across the world. For three days, we discuss current and future applications, and debate the priorities for both commercialisation, research and development, with leading representatives of the main public and private companies, research centres, and universities involved globally in the flow battery sector.

We thank our Organising Committee for their continued support in shaping the event’s content and activities.
