ABOUT THE CONFERENCE
The International Conference on Hydrogen Horizons (ICH2) is an international forum dedicated to hydrogen technologies, innovation, and collaboration across the full value chain. Organized within the framework of the H2 Green Valley Agenda, the conference aims to present key results of the Agenda while also bringing together researchers, innovators, policymakers, and industry leaders to discuss the role of hydrogen in shaping a resilient and sustainable world.
The first edition of ICH2 will take place in Lisbon, Portugal, from 21 to 24 September 2026, at the Museu do Oriente. Lisbon offers an inspiring setting for dialogue, collaboration, and the exchange of ideas, bringing together heritage, innovation, and an international outlook.
Over four days, ICH2 will offer a dynamic environment for scientific exchange and cross-sector engagement. The programme will include keynote lectures, technical sessions, poster presentations, thematic discussions, and technical visits, addressing major challenges and opportunities across the hydrogen sector.
As part of the dissemination and outreach efforts of the H2 Green Valley Agenda (www.h2greenvalley.pt), funded under the Portuguese Recovery and Resilience Plan (PRR) and managed by IAPMEI, the conference will highlight relevant developments and achievements of the Agenda while placing them in dialogue with broader scientific, technological, regulatory, and industrial perspectives.
By combining scientific exchange, industrial engagement, and institutional dialogue, ICH2 aims to strengthen knowledge-sharing, foster new collaborations, and establish itself as a reference platform for the hydrogen community.
Join us in shaping the horizons of hydrogen innovation.
Save the date and be part of the first edition of ICH2 — we look forward to welcoming you to Lisbon for four inspiring days of ideas, collaboration, and discovery.
ICH2 WITHIN THE H2 GREEN VALLEY AGENDA
The International Conference on Hydrogen Horizons (ICH2) is organized within the framework of the H2 Green Valley Agenda, funded under the Portuguese Recovery and Resilience Plan (PRR) and managed by IAPMEI.
The H2 Green Valley Agenda brings together a set of complementary projects across the hydrogen value chain, including the development of transmission, storage, and distribution infrastructures, with the objective of establishing an integrated and scalable green hydrogen hub in Sines. By connecting producers and consumers through shared infrastructure, the Agenda supports cost-sharing, fosters innovation, and accelerates the transition to a green economy.
The project includes the development of hydrogen transmission infrastructure, blending systems for injection into the gas grid, the adaptation of distribution networks, and pilot demonstrators supporting the transition towards a 100% green energy system.
Within this context, ICH2 reflects the integrated approach of the H2 Green Valley Agenda by addressing the full hydrogen value chain, from production to transport, storage, distribution, end-use applications, safety, regulation, and societal dimensions.
As part of the dissemination and outreach activities supported under the PRR framework, the conference serves as a platform to share results, promote knowledge exchange, and foster dialogue between research, industry, public authorities, and other stakeholders relevant to the development of the hydrogen ecosystem.
