Aviation pioneer Bertrand Piccard is preparing for the Climate Impulse project, aiming to fly a two-seater plane around the globe using green hydrogen. The project, backed by Airbus and others, seeks to demonstrate the potential for greener commercial flight. Initial test flights are planned for next year, with the main flight set for 2028. Despite challenges, including the need for untested technologies and the environmental impact of water vapor emissions, the team is optimistic about the future of hydrogen-powered aviation.
