Call for papers

The HEET 2025 is honored to invite all international stakeholders on hydrogen and fuel cells technologies and subjects relating to hydrogen production, storage, transport and end uses to participate in HEET 2025. For this purpose we issue this CALL FOR PAPERS. Submitted conference papers will be reviewed by technical committees of the Conference. English is the official language of the conference. We welcome paper submissions. Prospective authors are invited to submit full (and original research) papers in electronic format (PDF or DOC). To ensure the success of the conference, HEET 2025 will consist of guest plenary sessions, topical technical sessions of oral presentations, and technical sessions of posters.
