Japan has one of the largest worldwide reserves of geothermal energy, and it is expected to be developed for power generation via renewable energy. JFE Engineering was involved in the design and engineering of Matsukawa Geothermal Power Plant, which was the first geothermal power plant in Japan. We have also constructed steam separation plants, steam gathering pipelines, brine re-injection pipeline and associated instruments and control systems. Ever since 1966, JFE Engineering, as a pioneer, has been gaining experience in E.P.C. for nine geothermal power plants in Japan as well as plants in both Indonesia and Kenya.

JFE Engineering has developed
  - Optimum Operation and Design System “GEOSYS”;
  - High-performance Cyclone Type Steam/Water Separator; and
  - Corrosion, Erosion and Scale Presentation System.
In 2010, we began providing Binary Power Generation Units as well.

JFE Engineering promotes overall engineering of geothermal power generation from feasibility studies to construction, commissioning and maintenance.

JFE Engineering provides high-efficiency geothermal power generation systems consisting of production well head facilities, steam production facilities , steam gathering pipelines, brine gathering pipelines and re-injection facilities, and binary power generation facilities capable of utilizing both steam and hot water.

When driving turbines, steam separated from a geothermal resource is utilized directly by a normal flush power generation system, so super-heated steam (more than 200°C) is necessary. In contrast, binary power generation systems utilize geothermal resources, steam and/or hot water as a heating source to evaporate a fluid with a low boiling point, which drives the turbine. Therefore, it is possible to utilize low temperature (less than 200°C) geothermal resources.

In 2010, JFE Engineering entered into a business alliance for binary power generation system with Ormat Technologies, Inc. (USA). This binary power generation system boasts the highest level of reliability and efficiency as well as a global track record of more than 1.20 million kW. The generating units have a wide output range of 250 to 15,000 kW.

In 2012, JFE Engineering received an order for a Feasibility Study of Power Generation Utilizing Tsuchiyu Hot Springs from the Ministry of the Environment. Study results showed that a Binary Power Generation System would satisfy the required power output.  Tsuchiyu Hot Spring Cooperative Association and JFE Engineering are planning further study for commercialization as an independent power producer.
