Endorsed by the Ministry of Environment and Energy, the Lisbon Energy Summit & Exhibition 2025, the Iberian region's leading energy transition event, will welcome over 2,000 visitors to Lisbon, Portugal, a world leader in new energies and technological innovation, on 3 – 4 June 2025. 

Ministers, policymakers, project developers, investors and innovators will engage at a 2-day high-level strategic conference sharing insights into transitioning the E.U.’s energy system to one based on renewables and in line with the REPowerEU initiatives. Showcased across the exhibition's hydrogen & decarbonisation, solar and innovation zones are the products and projects that will deliver this cleaner, greener energy system.

Join the international exhibition as a visitor, or book your delegate pass to access the Strategic, Hydrogen & Decarbonisation and Climatetech conferences.

EVENT FORMAT

🎤 2 day multi-track Strategic Conference

Energy executives will analyse central themes to the transition energy supply mix, the onset of electrification, improvements in energy storage, future risks of oil supply disruption, emerging gas security challenges and the ongoing inflationary environment.

🌍 Hydrogen & Decarbonisation Conference

Offers solutions providers the opportunity to present their ideas and technologies to push forward the implementation of hydrogen. Visitors from utilities, IOCs, Government & Municipalities, Heavy Industry, Transportation, Shipping, Refining and Petrochemicals seeking pathways to net zero will be in attendance.

💚 Climatetech

Discover the latest technologies currently implemented in the fields of solar, wind, green hydrogen, storage, and batteries, and how they are enabling energy transition and supporting companies in achieving sustainability and net zero.

🧭 International Exhibition

Through specialised zones on the exhibition floor, 100+ exhibitors will showcase new products, solutions, and technologies across renewables (wind, solar, hydro, wave), green hydrogen, energy storage, decarbonisation, and climatetech.

☕ Networking functions

Across 14 hours of networking, attendees connected during breakfasts, networking lunches, pre-scheduled meetings via the app and a fantastic networking drinks reception at a rooftop location.

🎙️ 300+ Industry Leading Speakers

Key industry stakeholders will talk about decarbonisation through the accelerated adoption of clean fuels such as hydrogen and ammonia. On a tactical level, detailed discussion will take place around easing regulation to incentivise investment in renewables and technology that can unlock hybridisation of wind, solar and storage projects.
