Call for proposals – IFBF 2027, Barcelona
The call for proposals for the 18th International Flow Battery Forum is open from 1 November 2026 to 15 January 2027. The conference takes place on 22–24 June 2027 at the Barceló Sants Hotel in Barcelona, Spain, and online.
Can you tell us how to deliver an operating flow battery? Our audience at the International Flow Battery Forum wants to know how they can buy, install and operate a flow battery. It is a broad subject area: we want to know about the applications and benefits of flow batteries, and we need to understand where the batteries have come from. How are they made? What is the supply chain for the materials and components? How do we improve performance, cut costs and increase reliability?
We invite you to submit proposals for presentations, keynote addresses, interviews, panel discussions, posters and papers. More than 300 delegates from around the world are expected in Barcelona, across manufacturers, utilities, suppliers, policymakers, researchers, academics and students. The 2026 edition in Budapest attracted over 100 proposals.
We will continue to follow our theme of reporting on progress towards a strong flow battery industry, one that can deliver high volumes of flow batteries to meet the demands of a sustainable power sector. Deployments are increasing but the competition is still fierce. We would like to hear about technology improvements, cost reduction, manufacturing scale-up, supply chains, standards, and the operating experience of systems in the field.
Spain is building one of Europe’s largest renewable generation fleets, and the storage needed to firm it is being procured now. The country already hosts flow battery demonstration projects, including a 1 MW / 8 MWh system. Barcelona puts the Forum in the middle of that market, and the Barceló Sants Hotel sits directly above the city’s main railway station.
Papers are required at least six weeks before the conference so that they can be collated, reviewed and published in time. The papers are indexed and submitted to major libraries and reference services, and are collected in the IFBF Book of Papers – which now holds 821 papers across 16 editions, from 2010 to 2026.
Attendance at the conference counts towards Continuing Professional Development, and certificates of attendance are available on request. The conference language is English.
