Tokyo Governor Yuriko Koike called on start-ups, SMEs and local governments across Japan, Europe and Kazakhstan to collaborate and share best practices on green hydrogen technology in an interview with Euronews conducted during an official visit to Astana.

"I hope that knowledge sharing in forums like these will further drive innovation and accelerate the hydrogen implementation in various regions," Koike highlighted.

“With the goals of halving emissions by 2030 and achieving zero emissions by 2050, Tokyo is advancing a wide range of initiatives,” she continued.

Green hydrogen is produced using renewable energy, typically wind or solar power, to split water into hydrogen and oxygen through a process called electrolysis.

Because no fossil fuels are involved, it generates no carbon emissions, unlike "grey" hydrogen, which is made from natural gas and accounts for the vast majority of hydrogen produced today.
