Hoku Scientific's ( HOKU) shares gained more than 11% in anticipation of its earnings report and the president's State of the Union address late Tuesday.

In his speech tonight, President Bush is expected to call for increased government support for clean energy sources to reduce U.S. dependence on foreign oil. Hoku develops products used in hydrogen fuel cells and has recently entered the market for polysilicon, a substance used in solar panels.

Last week Hoku announced a seven-year, $370 million polysilicon supply agreement with Sanyo, with shipments planned to begin in January 2009.

Analysts are expecting the Kapolei, Hawaii-based company to report a loss of 2 cents a share on sales of $1.15 million. Hoku is due to report its third quarter after the close Tuesday.

Shares of the materials science and clean energy technology company were gaining 69 cents to $6.49.
