Bulgaria and Germany have solidified their commitment to cooperation in the energy sector by signing a declaration in Thessaloniki, Greece. The agreement, announced by Bulgaria's caretaker Energy Minister Vladimir Malinov and German Economy and Climate Action Minister Robert Habeck, emphasizes partnerships in hydrogen technology, renewable energy, green transition, and energy corridors. The focus is on promoting energy efficiency, security, decarbonisation, and the development of green energy corridors. The declaration also highlights the significant investments made in large-scale green projects aimed at transforming coal regions in Bulgaria to generate electricity from photovoltaics and green hydrogen. However, Bulgaria's political unrest, leading to frequent elections, is creating obstacles in accessing approximately €5 billion in stimulus funds, potentially impacting future green initiatives. Despite the challenges, Bulgaria and Germany's trade partnership, with an expected €23 billion trade volume by 2023, underscores the strategic nature of their collaboration. The meeting also emphasized the importance of Bulgarian-Greek cooperation for energy security in Europe, particularly with the upcoming operationalization of the LNG terminal near Alexandroupolis on 1 October.
