Capstone Turbines Provide Main Electrical Power for Green Ship

CHATSWORTH, Calif., April 7, 2011 (GLOBE NEWSWIRE) -- Capstone Turbine Corporation (www.capstoneturbine.com) (Nasdaq:CPST), the world's leading clean technology manufacturer of microturbine energy systems, continues to grow its presence in the marine market with a recent order for two C30 liquid natural gas (LNG) microturbines that will be installed on a Type C Tanker for inland shipping and will be certified by Lloyds Register of Shipping.

The two C30 LNG Capstone microturbines, which will be installed in May, will operate in an N+1 setting for main power supply on board. Heat from the microturbine exhaust will be used in an LNG vaporizer to provide fuel to the microturbine as well as the main propulsion engines.

"The customer selected low-emission Capstone microturbines for this innovative vessel to take advantage of Capstone's ultra-low emissions as well as our low maintenance requirements and high reliability," said Jim Crouse, Capstone's Executive Vice President of Sales and Marketing. "In addition, the microturbines can easily integrate with current onboard equipment and increase onboard comfort because there's no vibration and very low noise."

Capstone microturbines can serve as a low-emission onboard energy source for propulsion or to power auxiliary applications. The clean and green microturbines can meet strict regulations without additional exhaust aftertreatment, which means reduced service requirements and reduced costs.

"Capstone's influence will continue to grow in the marine market," Crouse said. "Customers are hungry for innovative solutions that comply with current and future emission and noise regulations."
