The JIVE project is showcasing the potential of hydrogen electromobility in Bulgaria with the implementation of 300 buses in various European countries. In Sofia, residents and visitors have the opportunity to experience free rides on a hydrogen bus, highlighting the benefits of green hydrogen produced sustainably. Prof. Daria Vladikova, leading hydrogen research at Thrace University, emphasizes the importance of Bulgaria's role in advancing hydrogen technologies and promoting a diverse energy mix for decarbonization. While countries like Germany and the UK lead in hydrogen programs, Bulgaria seeks to catch up and address transportation pollution with clean, zero-emission vehicles. The introduction of hydrogen buses in European cities underscores the growing trend towards sustainable transport solutions. Challenges remain, including the need for hydrogen refueling infrastructure, which is being addressed through initiatives like mobile charging stations. Bulgarian scientists advocate for greater support and recognition to drive hydrogen innovation and policy development at the European level, emphasizing the country's potential for leadership in the field. With each hydrogen bus costing around 600,000 euros and offering a range of about 400 km per charge, Bulgaria aims to leverage collaborative efforts and institutional support to participate in large-scale hydrogen projects, contributing to the country's sustainable energy transition.
