MHI Achieves 3000-Hour Operation Of SOFC-MGT System

Posted on October 19, 2009

Mitsubishi Heavy Industries (MHI) has achieved 3000 cumulative hours of operation of a 200 kW class combined cycle power generation system incorporating solid oxide fuel cells (SOFC) and a micro gas turbine (MGT). MHI began developing SOFC-MGT combined cycle power generation system in 2004 at MHI's Nagasaki Shipyard and Machinery Works under consignment by the New Energy and Industrial Technology Development Organization (NEDO).

MHI will further pursue reliability enhancement and system downsizing. The company is also working toward a business/industrial use system, combining SOFCs and an MGT in joint development with Toyota Motor Corporation. MHI has been conducting joint development with Toyota Motor Corporation since 2008. Toyota has an affiliate company, Toyota Turbine Systems, Inc. which sells MGTs.

MHI has been pursuing various power generation methods to reduce CO2 emissions, including high-efficiency thermal power generation systems, nuclear power systems, and renewable energies such as wind power and photovoltaic cells. As higher power generation efficiency is expected by combining SOFCs with other power generation systems, ranging from small-scale or under 1 MW, to large scale, several hundred megawatt, MHI views the development of large scale combined cycle power generation systems as a key challenge but with significant potential.
