South Korea witnessed a significant increase in hydrogen fuel demand, with consumption rising by 64% in 2024 primarily due to the expansion of hydrogen buses. The government plans to escalate the number of hydrogen buses to 20,000 by 2030, reflecting a strategic focus on sustainable transportation infrastructure. Hydrogen fuel technology boasts eco-friendliness, efficiency, and quick refueling times. While the adoption of hydrogen presents environmental benefits and energy diversification, challenges like infrastructure limitations, production costs, and safety concerns exist. South Korea explores various applications beyond buses, including hydrogen taxis and zero-emission freight transport. Emphasizing security and sustainability, the nation prioritizes adherence to safety standards and the production of green hydrogen. The global shift towards greener energy sources, including hydrogen, suggests a promising market outlook. By investing in hydrogen technology, South Korea positions itself as a key player in the evolving energy landscape, with potential impacts on global supply chains and economies.
