Notice of conclusion of technical licensing agreement on binary cycle power
generation system for ships

TOKYO, July 12, 2022 — MIURA CO.,LTD. (Head Office: Matsuyama, Ehime;
President & CEO: MIYAUCHI Daisuke, hereinafter referred to as “MIURA”) and Kobe
Steel, Ltd. (Head Office: Chuo-ku, Kobe; President & CEO: YAMAGUCHI Mitsugu,
hereinafter referred to as “Kobe Steel”) signed a technical licensing agreement(development, manufacturing, and sales) on binary cycle power generation*1 systems
for ships (hereinafter referred to as “binary power generation for ships”) on July 4,2022. In line with this agreement, MIURA aims to begin sales of binary power
generation for ships around 2025.
Reduction of GHG emissions and stronger environmental regulations in the shipindustry has led to a shift from oil fuel to LNG, and with efforts in transitioning to newfuels in order to achieve zero CO2 emissions from 2030 onward, MIURA is engaged indeveloping products that can handle new fuels with a focus on marine boilers. While
there is a push to transition to new fuels in order to reduce or achieve zero CO2emissions, energy needs on vessels are changing, and demand for energy-saving
measures (reducing fuel, etc.) is increasing.
MIURA and Kobe Steel jointly developed the binary power generation for ships whichuses the exhaust heat from the high-temperature turbocharger*2 supplied to the main
engine and conducted sea trials on a ship in 2017*3. Additionally, Kobe Steel has
conducted long-term ship trials including this system on four vessels, confirming
performance and durability in actual operations.
In addition to exhaust heat from the turbocharger, there are other unused heat sourceson the ship such as exhaust gas from the main engine and surplus steam. The volumeof such exhaust heat differs depending on the main engine load, however, utilizing thefeatures of the Kobe Steel screw binary power generator which is capable of stable
power generation across a wide range from low to high loads, MIURA is developing a newbinary power generation system and multiple unit system for ships with multiple heat sources.
By increasing power generation in the low to medium load range to decrease fuelconsumption on the main engine and expanding compatibility to vessels with large
main engines, we will further contribute to energy saving and reduced CO2.
The expander used in binary power generation for ships is provided by KOBELCOCOMPRESSORS CORPORATION.

As a marine equipment manufacturer, MIURA is engaged in commercializing auxiliary
marine boilers, incinerators, water generators, ballast water management systems, etc.
Utilizing our accumulated experience and strengths, we look forward to expanding ourlineup of binary power generation systems for ships, providing total solutions for ships,
and bolstering our after-sales service.

*1 Binary cycle power generation
This is a method that uses a heat source to heat and vaporize a medium with a low
boiling point to rotate the turbine with the generated steam.
It is called binary cycle power generation because it consists of two cycles: a heatsource system and medium system.

*2 Turbocharger
This device accelerates gas fed to the engine to increase density.
