Turboden, a Mitsubishi Heavy Industries company, is a global leader in the design, manufacture and service of Organic Rankine Cycle (ORC) turbogenerators, which harness heat to generate electric and thermal power from renewable sources (biomass, geothermal and solar energy) and waste heat from industrial processes, waste incinerators, engines and gas turbines, suitable for distributed generation.

With more than 300 plants in 32 countries, Turboden offers turbogenerators from 200 kW to 15 MW electric.


ORC technology can be efficiently applied to different fields of application:

  • exploitation of biomass, where cogeneration ORC plants produce heat and electric power from biomass with high efficiency and user friendly operation;
  • geothermal sources, where ORC technology is particularly suitable for the exploitation of medium-to-low-enthalpy sources;
  • heat recovery from energy-intensive industries (cement, glass, steel, other ferrous and non-ferrous metals) and from Oil&Gas processes, easy to integrate – even with inconstant heat sources – and completely automated, leaving the industrial user focused on its own production process;
  • combined cycles with reciprocating engines and gas turbines, minimizing the fuel consumption without adding complexity to the system;
  • waste to energy applications from waste incinerators (including sludge incineration);
  • solar thermal power applications, where Turboden units allow to convert the heat collected by solar collectors into electricity through an efficient thermodynamic cycle.

The company was founded in 1980 in Milan by Mario Gaia, Professor of Energy at the Politecnico di Milano and today Founder and Honorary Chairman of Turboden. Mario Gaia implemented his vision for ORC technology by using organic fluids, instead of water, in a closed thermodynamic cycle. Moreover, his close connection with the university has always ensured the recruitment of highly qualified R&D personnel.

In 2009 Turboden became part of United Technology Corporation (UTC), a worldwide leader in development, production and service for aero engines, aerospace drive systems and power generation gas turbines, to develop ORC solutions from renewable sources and waste heat worldwide.

In 2013 UTC exited the power market forming strategic alliance with Mitsubishi Heavy Industries.

In the same year Mitsubishi Heavy Industries acquired from UTC Pratt & Whitney Power Systems (now PW Power Systems, Inc.) and the affiliate Turboden.
