Toyota Tests Hybrid Power Generation System
« on: October 12, 2017, 11:28:56 AM »
A hybrid power generation system combining solid oxide fuel cells and micro gas turbines is being trialed by Toyota Motor Corporation at its Motomachi Plant in Toyota City, Japan. The pressurized combined power generation system was jointly developed by Toyota, Toyota's subsidiary, Toyota Turbine and Systems Inc., as well as Mitsubishi Hitachi Power Systems Ltd.
The trial operations will utilize the system as an internal power generation facility, with the aim of testing and evaluating the system's energy efficiency, performance, and durability.Schematic of the hybrid power generation system.

Natural gas reforming within the fuel cell yields hydrogen and carbon monoxide. Electricity is generated in the fuel cell through a chemical reaction between the hydrogen and carbon monoxide with the oxygen contained in the compressed air delivered by the micro gas turbine. Hydrogen and carbon monoxide not consumed by the fuel cell is delivered to the micro gas turbines together with heat and high pressure exhaust that is produced during power generation.
The 250 kW two-stage power generation system achieves a generating efficiency of 55%.
The scheme is being implemented as part of the "Technological Demonstration for targeting Mass-production of Pressurized Hybrid Power Generation System Consisting of Cylindrical Solid Oxide Fuel Cell and a Micro Gas Turbine" of the New Energy and Industrial Technology Development Organization.
