The International Hydrogen Aviation Conference (IHAC) Standards

IHAC 2020 & IHAC 2021 & IHAC 2022 & IHAC 2023 attracted high-level international speakers as well as a global audience discussing the role of hydrogen in aviation. This world's first platform is expected to become the most recognized international forum, gathering leading experts from the aviation sector with a special focus on hydrogen as one of the key solutions for decarbonisation.

Like aviation (with hydrogen addition onboard making it more challenging), we are continuously striving to set the highest standards for IHAC. We foresee the forum to emerge as one of the most prominent meeting places for the comprehensive exchange of industrial, technical & scientific information and for high-level networking. This requires everyone to follow the guidelines in order to ensure the delivery of a most successful event, discussing emerging technical breakthroughs in the hydrogen aviation industry.

We thank you in advance for your understanding and cooperation!
