Ida will begin with a quick introduction to GreenH, highlighting its commitment to advancing local hydrogen production as a key solution for sustainable energy. She will then introduce the Next Wave project, emphasizing its importance in the broader context of zero-emission initiatives. From there, Ida will delve into the main barriers identified for establishing zero-emission tradelines, particularly focusing on challenges in sea transport. Drawing from her experiences with the Bodø project, she will illustrate these obstacles with real-world examples, offering a grounded perspective on the difficulties faced. Finally, Ida will touch on some potential mitigation measures, exploring practical steps that could help overcome these challenges and pave the way for cleaner and more efficient transport solutions.
