The Joint Initiative for hydrogen Vehicles across Europe (JIVE 1), a major fuel cell bus project, has concluded with the deployment of 131 hydrogen buses in Germany, Italy, the Netherlands, and the UK, marking a significant step towards sustainable urban transport. Challenges related to hydrogen supplies and refueling stations were acknowledged, emphasizing the importance of addressing these issues for future commercial operations. The project, co-funded by the Clean Hydrogen Partnership, achieved key milestones such as meeting the target price for buses, exceeding fuel consumption expectations, and establishing long-term agreements with suppliers. Manufacturers expanded their base, developed the world's first fleets of double-deck fuel cell buses, and demonstrated a consistent range of up to 500 kilometers. The success of JIVE 1 has paved the way for further adoption of fuel cell buses, promoting sustainable urban mobility and supporting the EU's carbon neutrality goals. Statements from project leaders express pride in the project's accomplishments and emphasize the lessons learned and the collaborative efforts that have advanced Europe's fuel cell bus sector.
