Tried and tested engineering principles

Our Electric Turbo Compounding (ETC) technology is creating using established engineering principles to deliver unrivalled benefits to the power generation industry.

By using the established principles of turbocharging and turbo compounding we recover waste heat energy from the exhaust of reciprocating engines and convert it to free, grid-quality electrical power.

In this video, Paul Dowman-Tucker, CEO, explains how our ETC technology works, how the principles we employ are found in many household technologies, and why our ETC system is unique in the power generation industry.

How it works:

  1. A mass of exhaust gas, with high temperature and pressure flows from the engine and enters the turbo generator
  2. The stationary Nozzle Guide Vanes (NGV) will direct the flow toward the rotating rotor blades downstream
  3. The flow of exhaust gas passes over the turbine blades. The energy within the gas (high temperature and high pressure) is transferred to the rotor
  4. The gas exits the ETC system at close to ambient pressure, still at a relatively high temperature
  5. The spinning rotor turns the shaft which turns the alternator. The spinning alternator produces a non-stable AC current, which is exported to the Power Electronics unit
  6. The AC current produced by the alternator enters the Power Electronics’ module. This AC input current is converted to DC before the final conversion to a 3 phase AC grid standard (50/60Hz) output
