Hoku Scientific Announces TCS Engineering Contract for Hoku Materials' Polysilicon Plant

POCATELLO, ID and STURGIS, MI--(Marketwire - October 9, 2007) - Hoku Materials, Inc., a wholly owned subsidiary of Hoku Scientific, Inc. (NASDAQ: HOKU), established to manufacture and sell polysilicon for the solar market, and Dynamic Engineering, Inc., a process technology and engineering firm, today announced that they have entered into an Engineering Services & Technology Transfer Agreement for Dynamic Engineering to provide design and engineering services, and a technology license, for Hoku Materials to build a trichlorosilane production and purification unit at its planned polysilicon production plant in Pocatello, Idaho. Trichlorosilane, or TCS, is produced through the chlorination and purification of metallurgical-grade silicon, and is the primary material used to produce polysilicon in a Siemens reactor. The agreement announced today provides for Dynamic to provide the basic engineering package and related services for the TCS production component of Hoku's planned polysilicon plant, which will be integrated by Stone & Webster Inc., a subsidiary of The Shaw Group Inc., and Hoku's engineering, procurement and construction management firm, into the overall polysilicon production facility, and will be constructed by JH Kelly, Hoku's general construction contractor.

"We are pleased to have signed this TCS engineering agreement with Dynamic Engineering, which we believe will enable us to efficiently produce high purity TCS in our planned closed-loop polysilicon production plant," said Dustin Shindo, Chief Executive Officer of Hoku Scientific. "We expect that our polysilicon production costs will be lower if we produce our own TCS on-site, instead of purchasing it from third-party vendors."

Lee Kennedy, President of Dynamic Engineering, said, "We are impressed with Hoku's team and their approach to building a polysilicon plant, and we look forward to working with them on this exciting project."
