Strong technical and strategic support to Turboden on-going activities and future

development

• Focus on the energy/power business • Oriented to research and development • ORC technology complementary technical

solution for several MHI business (e.g. geothermal plants, gas turbines, etc.)

Turboden medium term business plan: larger sizes and

enhanced solutions

Turboden Board of Directors is composed of 5 members, 3 MHI senior representatives appointed members – direct and strong support to Turboden management

MHI engineering support added to Turboden engineering department for new/special solutions/projects (e.g. development of the direct exchange solution)

Worldwide presence of MHI to support Turboden activities Company development in foreign countries (e.g. after sales in Germany)

Improvement of Turboden organization [new company structure] and improvement of Turboden production capability [new warehouse] to support expected volume increase

Technical Advantages of Turboden proprietary turbine

27

A MORE EFFICIENT CHOICE • Average turbine isentropic efficiency: 85 to 90 % • Multi stage (4- 5 stages) axial turbines are less sensitive than

radial ones to discharge pressure variations, showing nearly constant efficiency over wide range of operating conditions

A RELIABLE TURBINE • Average plant availability > 98% on all the Turboden fleet • Operating speed: From 1500 rpm to 3000 rpm • Robust design, low rpm, and strict quality tests by Mitsubishi • Patented seals & bearing replacing system: short maintenance

procedures • Specialized local staff for maintenance

A PROVEN SOLUTION • The design of the turbine is carried out by Turboden representing the core know-how since 1980 • 318 Turboden ORC turbines successfully implemented with sizes from 200 kW to 20 MW • Proven experience with 9 different ORC fluids • Axial geometry is a traditional configuration, the most widely adopted in turbomachinery design, proven

with millions of working hours worldwide
