Ulsan, a major industrial city in South Korea, is at the forefront of the hydrogen economy with its ambitious Green Hydrogen Town project. This initiative aims to transform Ulsan into a global hub for hydrogen energy, integrating hydrogen into various aspects of urban life, from residential heating to transportation and industrial power generation.
Residential Innovation: Carbon-Free Living
In October 2024, Ulsan unveiled the world's first carbon-free hydrogen apartment complex in the Yuldong District. This development utilizes by-product hydrogen from nearby petrochemical complexes to generate electricity and provide heating through a combined heat and power (CHP) system. The initiative not only reduces carbon emissions but also cuts energy costs for residents by approximately 30%
Advancing Hydrogen Mobility
Ulsan has been a pioneer in hydrogen mobility since 2009, with the establishment of South Korea's first automobile hydrogen charging station. The city continues to expand its hydrogen infrastructure, including the introduction of hydrogen-powered taxis and the development of hydrogen trams, set to commence operations in 2028 .
Industrial Applications and Power Generation
The city is investing heavily in hydrogen-based industrial applications. Korea Southern Power has agreed to build a 135 MW clean hydrogen power plant in Ulsan, expected to be operational between 2029 and 2031 . Additionally, Lotte SK Enerroot plans to install three eco-friendly hydrogen fuel cell power plants, supplying approximately 290,000 MWh of electricity annually starting in 2026
Strategic Partnerships and Global Recognition
Ulsan's commitment to hydrogen energy has attracted international attention. The city has hosted delegations from countries like Uruguay, Taiwan, and Indonesia, showcasing its hydrogen infrastructure and sharing best practices . Collaborations with industry leaders, such as Hyundai Motor Company, aim to develop hydrogen-powered vehicles, including the country's first hydrogen tractors .
Ulsan's Green Hydrogen Town exemplifies a comprehensive approach to building a sustainable, hydrogen-based urban ecosystem. Through innovative residential solutions, advancements in mobility, industrial applications, and international collaborations, Ulsan is setting a precedent for cities worldwide aiming to transition to a carbon-neutral future.
