GDI and TICA Thermal to supply
medium-and large-scale EXERGY binary generators

Geothermal Development & Investment Inc. (Head Office: Minato-ku, Tokyo, President: Tomofumi Ono, hereinafter referred to as ‘GDI ‘) has signed a distributor agreement with TICA Thermal of TICA Group, a major Chinese air-conditioning manufacturer, for medium and large binary generators *1 from EXERGY International Srl (hereinafter referred to as ‘EXERGY’).

Binary generator of EXERGY

※ 1: Binary power generation is a system in which heat is exchanged to a medium with a boiling point lower than that of water (CFC substitute, silicon oil, etc.), and the turbine, etc. is rotated by a vaporized medium to generate electric power. It is said to be binary power generation because it generates power using two thermal cycles, a heat source system and a medium system, and this cycle is called ORC (Organic Rankine Cycle).

■ Background to distributorship agreement

GDI invests in geothermal power projects, creates, and operates geothermal power projects in collaboration with local communities, and designs and operates geothermal power plants. The company also imports and sells generators and various equipment from overseas.

Recently, the acquisition of EXERGY by TICA Thermal has resulted in the expansion of its product scope, enabling TICA Thermal to offer medium and large ORC power systems (binary generators) from 1MW to 28MW per unit to the market.

This conclusion of a dealer contract with TICA Thermal means that GDI will be an authorized distributor in Japan for binary generators developed and manufactured by EXERGY.

■ Distribution Agreement contents

The binary generators handled so far by GDI were U.S. Electratherm (75kW, 120kW) and Chinese TICA (280kW). However, with the addition of EXERGY (1MW-28MW), GDI will be the only Japanese company that can handle all the types of binary power generation: small, medium, and large. GDI will take advantage of this strength to promote the further dissemination of geothermal and unused industrial waste heat power generation and contribute to the realization of a sustainable society.

■ About EXERGY

With its technological capabilities and high level of adaptability, EXERGY ranks third in the world in binary generators, with a total installed capacity of more than 470MW.

EXERGY's core strength comes from its unique, multistage, highly efficient Radial Outflow Technology (ROT), which can achieve efficiencies of up to 30%, the world's highest level for binary generators. With its unique ROT technology, EXERGY has developed 2 pressure level vapor application with single turbine disk, offering up to 20% more power than other technology. Besides, a distinctive and patented design of built-in mechanical group that is intended to maintain longer life of bearing can significantly reduce downtime of system, offering higher availability year-round.

Although a few types of refrigerants are normally used, EXERGY have used 11 different types of refrigerants in its projects, while keeping testing new fluids for future utilization. This has enabled us to accommodate temperatures ranging from 90°C to 350°C, from a variety of applications, including geothermal power generation, factory waste heat power generation, biomass power generation, and solar thermal power generation.

“Sanko Binary Power Plant” in Matsue, Shimane Prefecture: construction completed in March 2020

Press Release

“Sanko Binary Power Plant” in
Matsue, Shimane Prefecture: construction completed in March 2020
- First example ofa PC280 binary generator used for industrial waste heat power generation in Japan.

GPSS Engineering Inc. (Head Office: Minato-ku, Tokyo, CEO: Phillip Richards, ‘GPSS’) and SANKO Co., Ltd. (Head Office: Sakaiminato City, Tottori Prefecture, President & CEO: Masaki Miwa, ‘SANKO’) held the opening ceremony for the "Sanko Binary Power Plant" in Matsue City, Shimane Prefecture on Friday, 27th March. This is the first time the binary generator*1 PC280*2 will be used for industrial waste heat power generation in Japan (other cases exist overseas). Currently, both in Japan and overseas, this generator is being used for geothermal power generation.

*1 Binary power generation is a system in which heat is exchanged with a fluid medium with a boiling point lower than that of water (CFC substitute, silicon oil, etc.). The vaporized medium rotates a turbine to generate electric power. It called binary power generation because it generates power using two thermal cycles, a heat source system and a medium system. The cycle is called the ORC (Organic Rankine Cycle).

*2 PC280 is a binary generator manufactured by major Chinese air-conditioning manufacturer, TICA. Geothermal Development & Investment Inc. is the Japanese import agent.

Binary generator PC280

■ Background and Future Prospects for the introduction of Binary Generator PC280

SANKO already had a power generation system that uses waste heat from the waste incinerator at the site. However, even after passing through the first generator there was still ample recoverable thermal energy in the system. Utilizing that heat, the PC280 binary generator system will be installed in series with the existing generator, thus maximizing the thermal recourse and leading to a reduction in CO2 emissions.

SANKO actively contributes to the local community and the wider environment by introducing and examining the use of a wide variety of renewable energies in addition to the above power plant, such as photovoltaic power generation, methane power generation, and the effective use of waste heat. In introducing this binary power plant, SANKO utilized a fiscal 2019 subsidy* designed to offset the cost of measures to control carbon dioxide emissions.

*(Program to promote the development of a low-carbon social system through the efficient use of unused resources such as waste heat and spring water).

GPSS's philosophy is to realize a truly sustainable society through pursuing businesses related to sustainable energy generation that utilize local resources in Japan. GPSS aims to achieve ‘Grid Parity’, where the cost of sustainable electricity generation is less than those by tradition generation methods.

Both SANKO and GPSS look beyond the introduction of this binary power plant and continue to contribute to the field of sustainable energy.
