Jeju Island in South Korea, known for its natural beauty, has emerged as a hub for green technologies, including hydrogen energy. Through wind and solar-powered electrolysis, Jeju produces green hydrogen without CO₂ emissions, powering homes and transport with fuel cells and hydrogen buses. Tajikistan, aiming to produce 1 million tons of green hydrogen annually by 2040, seeks to follow this sustainable path. The country plans to utilize its hydro potential and abundant sunlight to drive hydrogen production, targeting both domestic consumption and exports to Central Asia. Tajikistan can learn from South Korea by establishing experimental regions for renewable energy, leveraging wind resources, introducing hydrogen-powered public transport in cities, and implementing public-private partnerships for a green economy transition. With active implementation of new technologies and international cooperation, Tajikistan has the potential to emulate Jeju's success and advance its energy transition towards a sustainable future.
