The UK’s innovation agency, Innovate UK, has awarded funding of over £1m to support the development of marine-capable Electric Turbo Compounding (ETC) systems through a collaborative project between Bowman Power Group, Rolls-Royce PLC, Lloyds Register and University College London.

Southampton-based Bowman Power Group is the lead partner in the 24 month project, funded by Innovate UK under the ‘Vessel Efficiency II: Better Systems at Sea’ program. The project scope will see Bowman, Rolls-Royce, Lloyds and UCL develop and test a larger variant of Bowman’s proven energy efficiency technology, which recovers waste energy from the exhaust of reciprocating engines to produce grid-quality electricity.

To date, Bowman’s Electric Turbo Compounding systems have typically been integrated with stationary power generation engines in the 500kW-1.2MW range, delivering improved energy efficiency and reduced fuel consumption by 4-7%, or additional power output of up to 8%. Under the Innovate UK funded project, the consortium will design new ETC systems for marine application, for applications on engines in the 2MW-4MW range.

Paul Dowman-Tucker, Engineering Director, Bowman Power Group, spoke of the project:

“We’re delighted to lead this project, and work with our partners to explore the marine applications for Electric Turbo Compounding technology. Our expertise in the stationary power generation sector and our pursuit of innovation in our product strategy positions us well to develop energy efficiency solutions for new markets.”

Alastair Sim, Technologist at the Rolls-Royce Strategic Research Centre, also commented on the project:

“The topic of waste heat recovery is a growing area of interest for Rolls-Royce as we seek to continually improve our systems and enable our customers to produce power that is not only fuel efficient and economical but also environmentally responsible. We have experience and expertise in the challenges and opportunities of supplying power to the marine and land-based power generation sector gained through many years of delivering outstanding products to customers. We will draw on this experience throughout this project as we look to gain a deeper understanding about the impact electric turbo compounding will have on our engines & systems. The outcome of this project will hopefully allow us to continue to provide our customers with cutting edge power systems.”
