The South Korea green hydrogen market consists of all of the activities involved with creating, transporting, and using hydrogen made through the process of electrolyzing water using only renewable energy to create hydrogen without a net emission of greenhouse gases. South Korean’s are beginning to see the value of using green hydrogen as a key clean energy resource that could help reduce emissions from industries that are hard to decarbonize such as heavy industry, transportation, and electric power and help to secure energy supplies since South Korea relies on importing fossil fuel-based energy sources for nearly all of its energy needs.

The green hydrogen in South Korea are backed by government support, including the Hydrogen Economy Roadmap and accompanying policy framework, which set ambitious targets and regulatory support mechanisms for clean hydrogen development. By 2050, the country aims to produce about 27.9 million metric tons of clean hydrogen annually, which includes 3 million mt of green hydrogen and 2 million mt of blue hydrogen, while importing the remainder of its clean hydrogen needs.

As technology advances, South Korea’s green hydrogen providers are now using highly efficient solid oxide electrolysis systems, with digital optimization for increased operational efficiency through electrolysis technology, demonstration projects, and integration of hydrogen production, storage, mobility, and applications. Through these efforts, they are creating new integrated renewable hydrogen production systems in both the industrial and transportation sectors thereby improving overall systems performance, and reducing lifecycle costs across all systems in South Korea.

Market Dynamics of the South Korea Green Hydrogen Market:

 The South Korea green hydrogen market is driven by the strong government policy support, increasing industry demand for decarbonization, strategic efforts to diversify energy sources, government’s financial incentives, strong regulatory frameworks, the growing focus on clean mobility, hydrogen fuel cells, and hydrogen infrastructure across industries further propels market growth.

The South Korea green hydrogen market is restrained by the high production costs of green hydrogen high capital intensity of renewable energy and electrolyzer technologies, intermittent nature of renewable power, and competition from other renewable solutions.

The future of South Korea green hydrogen market is bright and promising, with versatile opportunities emerging from the energy supply chain that is both efficient and adaptable, to support export-based industries, manufacturing facilities, and business growth while also making manufacturing processes cleaner and less carbon-intensive through modernization and less energy reliance. The growing application of hydrogen technologies to transportation and electric power generation and their integration into a larger energy and industrial policy environment creates significant opportunities for South Korea to become a leader in the creation of a sustainable energy economy by developing green hydrogen as a core element of such an economy.

Market Segmentation

The South Korea Green Hydrogen Market share is classified into technology and distribution.

By Technology:

The South Korea green hydrogen market is divided by technology into proton exchange membrane electrolyzer, alkaline electrolyzer, and others. Among these, the alkaline electrolyzer segment held the largest revenue market share in 2024 and is predicted to grow at a remarkable CAGR during the forecast period. Large scale industrial demand, cost effectiveness, long operational lifetimes, reliable supply chain, and well-established manufacturing base of green hydrogen all contribute to the alkaline electrolyzer segment's largest share and higher spending on green hydrogen when compared to other technology.

By Distribution:

The South Korea green hydrogen market is divided by distribution into pipeline and cargo. Among these, the pipeline segment dominated the share in 2024 and is anticipated to grow at a remarkable CAGR during the forecast period. The pipeline segment dominates because of cost effective and efficient means for transporting high volumes of hydrogen over long distances, essential for connecting production sites to industrial clusters, and infrastructural growth in South Korea.
