South Korean chemical and energy company OCI Holdings has unveiled plans to expand its solar-grade polysilicon output from its current level to 70,000 metric tons per year by 2029, representing a doubling of the firm's existing production capacity.

Targeting US Industrial Demand

The expansion is explicitly oriented toward serving customers in the United States, with OCI Holdings citing demand from the artificial intelligence and space industries as the primary drivers. The convergence of these sectors with solar-grade polysilicon demand reflects a broader shift in how advanced manufacturing materials are being positioned — not solely as inputs for conventional photovoltaic installations, but as components relevant to next-generation technology infrastructure.

Scale of the Buildout

OCI Holdings has set 2029 as the target year for reaching the 70,000 metric ton annual production threshold. The company has not disclosed specific facility locations, capital expenditure figures, or intermediate production milestones in the information made available through these reports. The doubling of capacity represents a significant commitment by a South Korean producer at a time when the global polysilicon supply chain remains heavily concentrated among a small number of manufacturers.

Market Context

Polysilicon is a foundational material in the production of silicon wafers used across both photovoltaic solar panels and semiconductor applications. Demand signals from AI-related data center buildout and the commercial space sector suggest that high-purity silicon materials are drawing interest from industries beyond traditional solar markets. OCI Holdings' announcement positions the company to capture a larger share of US-oriented demand as supply chain diversification away from dominant Chinese producers continues to be a policy and procurement priority for American buyers.
