A consortium led by Bowman Power Group has created a new electric turbo compounding (ETC) technology to increase marine engine efficiency and reduce ship emissions.

The project was part-funded by Innovate UK, the UK’s innovation agency, and a leading research and innovation hub. Key engine original equipment manufacturer (OEM), certification and academic partners – Rolls-Royce Power Systems (RRPS), Lloyds Register and University College London (UCL) – provided guidance and support. In total, the project cost £1.5 million.

Bowman put forward the technology as the basis for development, whilst RRPS provided key information and simulation results for their MTU Series 4000 M93 engine.

Bowman worked with the Marine Research Group at UCL to determine the feasibility of ETC technology across a range of marine fleet sectors. Specifically, UCL developed a system modelling approach to explore the benefits, performance, limits, secondary impacts and expected results, all of which provided the necessary justification for the project to continue.

Following completion of modelling, Bowman moved forward with the testing of seven different turbo generator and power electronics prototypes in different applications.

As a result of this work, Bowman was able to deliver a road map, validated with testing, to produce a marine-capable ETC system based on its flagship ETC 1000 product. The consortium demonstrated the potential of the technology in achieving considerable fuel savings of up to 7.8% and a reduction in CO2 emissions.

Paul Dowman-Tucker, CEO of Bowman, said: “In the past 12 months we have explored and successfully entered a number of new markets, including active discussions with two large marine engine OEMs and a major ferry operator. The support of Innovate UK, and our partners, went a long way towards making this happen.  We are very grateful to all the parties involved for their help with this achievement.”
