The H-100 gas turbine, appreciated for its high efficiency, has been used by customers aiming for improved efficiency of power generation plants as a replacement for older existing gas turbines. Due to its dual-shaft configuration, the H-100 is also suitable for purposes other than power generation including driving machinery, and application to large LNG plants is under examination. Recently, the attainment of further efficiency has allowed the H-100 to widely meet user expectations as a product for new power generation, replacing existing facilities, and driving machinery. The H-100 was called the H-80 in replacement projects of existing plants because the permitted operation output was about 80MW, and now the name has been changed to the H-100, which is derived from the gas turbine rated output of 100MW class.
