Researchers from the UK and China collaborate to develop offshore renewable energy technologies
Five new projects to develop offshore renewable energy (ORE) technologies have been announced by collaborative research teams from the UK and China.
The projects have been designed to push forward in the move towards low-carbon economies in both the UK and China, by developing safe, secure, cheap and efficient provision of clean energy.
Each three-year-long project will use environmental science, technology and engineering to tackle key challenges affecting the development of ORE systems, such as offshore wind, wave and tide facilities, and maximise their environmental and socio-economic benefits.
The Engineering and Physical Sciences Research Council (EPSRC) and the Natural Environment Research Council (NERC) are supporting the projects with almost £4 million of funding, which will be distributed from the Newton Fund.
“The UK is a world leader in offshore wind which helps us meet our climate commitments while we grow the economy and create jobs,” says Richard Harrington, Minister for Energy and Industry, commenting on the funding.
The latest data published by the government in 2017 showed that a record 47 per cent of the UK’s electricity was generated by clean energy sources in 2016. Overall, renewable sources - which include onshore and offshore wind, solar farms, hydroelectric dams and biomass – accounted for 25 per cent of the UK’s electricity generation.
“This £4 million investment will support collaborative research into the next generation of offshore technologies with one of our largest global trading partners, unlocking further opportunities for projects across the UK and the rest of the world,” says Harrington.
The projects will help to determine the best sources of offshore renewable energy and the best locations for implementing new technologies, and help to develop new designs so that structures are resilient to extreme events such as typhoons and earthquakes.
It is hoped that the projects will also encourage the sustainable development of ORE systems, which will in turn kick-start new and improved design methods, such as floating wind farms, and assess the suitability of current standards and methods.
Such developments will also showcase the potential of ORE technologies to provide stable power supply for island and coastal communities in the UK and China, and improve understanding of the resources available under different conditions in both countries.
The projects have been funded as part of the Joint UK-China Offshore Renewable Energy programme, and have been supported by the National Natural Science Foundation of China (NSFC), amongst others.
“The Joint UK-China Offshore Renewable Energy programme will build on a successful history of international collaboration between EPSRC and NERC in the UK, and the NSFC in China, across a range of topics,” says Philip Nelson, EPSRC’s chief executive.
“This multidisciplinary programme has already delivered invaluable research on reducing energy demand at the city scale, the integration of electric vehicles and grid scale energy storage. These new projects bring together some of the leading minds in this field from the UK and China to increase our capacity to generate and distribute affordable, safe and clean energy.”
It is hoped that the projects will ultimately promote economic development in China by bringing down the cost of energy and increasing understanding of the environmental processes that can lead to climate change as well as addressing the population welfare issues associated with a reliance on fossil fuels.
“In the long run, it is vital to develop high-efficiency clean energy for a sustainable society,” says Che Chengwei, of the NSFC. “We are delighted to see the ongoing development of UK–China research collaborations, and believe these newly-funded projects lead to positive outcomes that will further strengthen bilateral cooperation.”
Resilient Integrated-coupled FOW platform design methodology (ResIn) – EP/R007519/1
The vision of this multi-disciplinary project is to provide a foundation to develop and demonstrate an integrated approach to system resilience for ORE in China and the UK, improving energy security while reducing environmental impacts. The proposal builds on environmental resource assessment techniques and data that enable enhanced characterisation methodologies with a focus towards localised environmental conditions and extremes. The engineering focus lies on the quantification and validation of the load reduction potential of novel floating offshore wind platform innovations.

Farming the Environment into the Grid: Big data in Offshore Wind (FENGBO-WIND) – EP/R007470/1
The FENGBO-WIND project aims to utilise the newest developments in high-performance computing, physics-based modelling and data science, to create a new generation of predicting capabilities that support the design and operation of more economical offshore wind farms, while assessing and seeking to minimise their environmental impact.

Extreme wind and wave loads on the next generation of offshore wind turbines – EP/R007632/1
The aim of this project is to improve the design methodology for offshore wind turbine farms, leading to a reduction in environmental impact, reduction in design uncertainties and ultimately reduced cost of energy. Key themes that will be addressed include: the modelling of the ocean environment in typhoon conditions in potential candidate areas for offshore turbines in China; the creation of realistic environmental load time-histories on turbines; analysis of the structural and geotechnical design of turbines under ultimate state limit and fatigue loadings; and activities aimed at the establishment of long-term collaboration between the UK and China partners.

Modelling, Optimisation and Design of Conversion for Offshore Renewable Energy (UK-China MOD-CORE) – EP/R007756/1
The project aims to advance the use of virtual prototyping in the design and optimisation of ORE power takeoff (PTO) systems. Advances in virtual prototyping, which involves the use of numerical, analytical and empirical models to create and validate designs before the creation of physical PTO prototypes, can reduce the risks to offshore development through evaluation of difference performance and environmental metrics and interactions between separate system aspects. It can also address operating challenges such as availability by revealing stress characteristics and confirming the effectiveness of operation and management strategies for electrical generators and power converters.

Investigation of the novel challenges of an integrated offshore multi-purpose platform – EP/R007497/1
The project proposes a multi-disciplinary approach to tackling challenges facing the integration of different offshore technologies, such as renewable energy and aquaculture, in a multi-purpose platform (MPP) system, finding synergies in the manufacturing, installation, operation and decommissioning costs of the different facilities, lowering the overall cost. MPPs have the potential to save money, reduce overall impact and maximise socio-economic benefits. It will develop approaches to assess the feasibility of an MPP system and showcase this potential through two case studies, one focusing on an island community in China and one in the UK.
