USP Oman 100,000 tpa Polysilicon Project Officially Commences Operations with SLG Green Hydrogen Systems

On February 5, United Solar Polysilicon (USP)’s 100,000 tpa polysilicon project in Oman — one of the world’s most technologically advanced polysilicon plants — was officially commenced operations at the Sohar Freezone.

The project represents a key component of the Middle East photovoltaic value chain and serves as a new connection point linking PV supply chains across Europe, Africa, and Asia.

The USP Oman project places higher requirements on equipment reliability, technical performance, efficiency, and energy consumption.

In the hydrogen production section, #SLG(Shuangliang) supplied 4 sets of green power intelligent hydrogen production systems with core performance indicators at an industry-leading level. The system achieves:

Current efficiency :up to 98%

DC power consumption down to 4.37 kWh/Nm³ H₂ (flowmeter method)

Rated operating current density : 6,000 A/m²

Hydrogen-in-oxygen concentration of ≤ 1.03% at 30% load,

ensuring high safety,fast response capability and stable operation

Looking ahead, SLG will continue to build on its core technologies and innovation-driven approach, working closely with global partners to support the development of clean energy worldwide.
