Tokyo Governor Yuriko Koike, during her official visit to Astana, Kazakhstan, called for enhanced collaboration among start-ups, SMEs, and local governments in Japan, Europe, and Kazakhstan to advance green hydrogen technology. In an interview with Euronews, she stressed the importance of sharing best practices to foster innovation and accelerate the implementation of hydrogen solutions. Tokyo is committed to halving emissions by 2030 and achieving zero emissions by 2050 through various initiatives. Green hydrogen, produced from renewable energy sources, presents a sustainable alternative to traditional hydrogen, which is often derived from fossil fuels. However, the high production costs and the need for extensive infrastructure investment pose significant challenges. Koike also met with Kazakh President Kassym-Jomart Tokayev to discuss future cooperation and celebrate the 10-year anniversary of their Enhanced Strategic Partnership. The discussions included energy security and the potential for collaboration in various sectors, including digital transformation and agriculture.
