Integrated Energy System

From Ammonia to Hydrogen, From Hydrogen to Power

Seowoin's ammonia-hydrogen integrated energy system is an energy conversion system that packages ammonia cracking, hydrogen purification, and fuel cell integration into a single unit. Ammonia is an energy carrier for storing and transporting hydrogen, which can be converted back to hydrogen at the point of demand. Seowoin is developing an integrated system that converts ammonia to hydrogen, produces high-purity hydrogen through a purification process, and then generates electricity in conjunction with a fuel cell.

    Examples: coastal vessels, government vessels, passenger ships, cruise ships, port equipment, ship auxiliary power.

  2. 02 Power Generation

    Can be utilized for land-based power generation, distributed power, and emergency power in conjunction with ammonia storage infrastructure. Even in areas with insufficient hydrogen pipeline networks, on-site hydrogen production and power generation based on ammonia is possible.
    Examples: distributed power, off-grid power, industrial complex power supply, emergency power, microgrids.

  3. 03 Heavy Industry

    Ammonia-based hydrogen supply technology can be applied to industrial processes requiring high-purity hydrogen. It can be used as a hydrogen supply source for low-carbon process transition in steel, chemical, refining, and materials industries.
    Examples: steel, chemical processes, refining, materials industry, industrial heat sources.

  4. 04 Heavy Mobility

    Large mobile units requiring long-range operation and high output may be difficult to address with batteries alone. Ammonia-based hydrogen conversion systems can be extended as clean power systems for commercial vehicles, heavy equipment, and special mobile units.
