£4.3M Grant to Accelerate Combined Wind and Wave Power Technology

Marine renewables technology developer Marine Power Systems has been awarded £4.3 million by the European Regional Development Fund to accelerate the development of a floating offshore wind and wave technology that could transform the opportunities for energy generation in deep water locations. For more information see the IDTechEx report on Wave, Tidal and Hydro Power 1W-10MW 2018-2038.
The EDRF funding, which is part of a £6.2million project under the Cornwall and Isles of Scilly Local Enterprise Partnership scheme to promote research and innovation, will enable MPS to launch an extensive programme of work on the DualSub, which the company launched earlier this year. The announcement comes just weeks after Marine Power Systems secured investment from the Welsh European Funding Office for £12.8 million to design, build and test a full-scale WaveSub device.
WaveSub is a wave energy generation device designed to provide easy operation and maintenance at sea alongside low cost transportation and installation. Scaleable to over 10MW in size, the device is in the final stages of development and testing by Marine Power Systems ahead of commercial readiness. WaveSub's high level of stability in deep water prompted Marine Power Systems to explore its suitability for use as a platform for wind turbines, particularly in locations where wind speeds are high but water depths make a fixed base turbine too costly to install - a constraint widely recognised in the sector.
Initial tests revealed Marine Power Systems's approach could provide a strong, stable platform on which a turbine could be installed, enabling the simultaneous capture of wave and wind energy from the ocean. This led to the development of a combined floating offshore wind and wave device, DualSub, and a floating offshore wind device - WindSub.
Both DualSub and WindSub have successfully completed prototype stability tests, detailed computational simulation and cost of energy modelling. Positive results have led Marine Power Systems to accelerate the development of both devices and the £4.3million of ERDF funding will enable Marine Power Systems to move through a significant programme of work to a point of demonstrator sea-testing, before progressing to a point of commercial readiness in 2023.
Says Dr Gareth Stockman, Chief Executive Officer at Marine Power Systems: "The UK floating offshore wind sector offers huge opportunity for low carbon energy generation. We're delighted to have secured this funding from the European Regional Development Fund and would like to thank them wholeheartedly for their support. It is investment such as this that will unlock new markets for UK skills, products and expertise as well as play a vital role in the UK Government's legally binding target of net-zero emissions by 2050."
Dr Graham Foster, Chief Technical Officer at Marine Power Systems commented "Following extensive testing and computational modelling over the last 2 years, we've produced some hugely encouraging results regarding the potential viability of DualSub as a combined wave and floating offshore wind technology. This funding from the ERDF comes at a perfect time and will enable the Marine Power Systems team to progress with the next phase of research, design and testing of DualSub at sea."
The announcement of Marine Power Systems's plan to expand into the floating offshore wind sector follows a report published by the International Energy Association in October which predicts offshore wind generation will grow 15-fold to emerge as a $1tn (£780bn) global industry in the next 20 years and will prove to be the next great energy revolution. In a speech earlier this month, the UK Prime Minister Boris Johnson committed to help deliver a green industrial revolution, with a pledge to increase the UK's current offshore wind capacity from 8.5GW to 40GW by 2030.
The UK currently generates 8% of its electricity from offshore wind. Around 70% of offshore wind farms are located along the east coast of the UK where oceans are shallower and fixed base turbines are easily installed. DualSub and WindSub have the potential to open up new areas of coastline in the UK where wind speeds are higher but water depth is greater and the installation of fixed base wind turbines are deemed too expensive.
