HS Hyosung Energy Solution Korea Plans Silicon Anode Plant

HS Hyosung Energy Solution Korea Silicon Anode Plant Investment

HS Hyosung Energy Solution Korea silicon anode plant plans are moving forward through an investment agreement with Ulsan Metropolitan City. The company will invest a total of KRW 1.2 trillion (JPY 136.8 billion) in the city to establish a mass-production system for silicon anode materials by 2030. The investment is planned in three phases, creating a staged approach toward the targeted production system. The agreement marks a significant step in the company's effort to establish silicon anode material manufacturing capacity in South Korea.

Three-Phase Investment Plan Targets 2030

The planned investment will be carried out across three phases, with the overall program focused on establishing mass-production capabilities for silicon anode materials by 2030. The first phase represents KRW 300 billion (JPY 34.2 billion) of the total KRW 1.2 trillion investment. This initial spending is designated for construction of MPK-1, a silicon anode material plant in Ulsan. The phased structure provides the basis for expanding production capacity over the course of the investment program while maintaining the company's stated target of a mass-production system by 2030.

MPK-1 Plant Planned for 2028 Completion

Under the first phase, HS Hyosung Energy Solution Korea plans to construct MPK-1 with an annual production capacity of 5,000 tons. Construction is targeted for completion by the first quarter of 2028. The facility is intended to provide the initial production capacity within the broader silicon anode material investment program. The KRW 300 billion first-phase investment therefore establishes both the first manufacturing site and the initial annual output capacity identified in the agreement with Ulsan Metropolitan City.

HS Hyosung and Umicore Joint Venture

HS Hyosung Energy Solution Korea is a joint venture formed by HS Hyosung Group and Belgian materials manufacturer Umicore to enter the silicon anode material business. The ownership relationship brings the two companies together around the development of this materials business, while the investment agreement provides a framework for establishing production capacity in Ulsan. The planned MPK-1 facility and subsequent investment phases are therefore part of the joint venture's broader effort to build a mass-production system for silicon anode materials through 2030.

Industry Impact & Outlook

The investment establishes a defined manufacturing expansion path for silicon anode materials in South Korea, with MPK-1 providing an initial 5,000-ton annual capacity and later phases intended to support the 2030 mass-production objective. For the local automotive and battery-materials ecosystem, the development could increase domestic availability of silicon anode materials as the planned capacity is built. The joint venture structure involving HS Hyosung Group and Umicore also connects the project to established materials expertise, while the three-phase investment plan indicates that additional development will follow the first facility. Construction progress and subsequent investment phases will determine how the planned production system develops.
