Established devices are already optimised so have minimal opportunity to produce a performance step change; Limit of Economic Viability of Devices


Novel concepts, e.g. alternative turbine forms or wave harvesting devices, offer a disruptive step forward; To design to lower (for instance) the velocity of flow whilst achieving economic viability

Context And Need

A step change in cost reduction may only come from the development of novel technologies and new ideas for renewable energy generation. This can apply to all of ORE, where larger novel turbines may displace the conventional 3-bladed horizontal axis turbine (whether in wind or tidal). In wind, wave and tidal there is considerable scope for new disruptive concepts, if they can be conceived.

The areas for deployment would/could be expanded considerably by driving down the lower limits of the resource.

To date, extreme conditions have been researched but not necessarily the lower limits which has a very different challenge


Reducing the economic viability opens the potential for device deployment in UK; South America etc.

Impact Potential

The impact potential could be very significant. In order to displace existing technology there would need to be substantial CAPEX and OPEX advantages, perhaps through economies of scale at device level. The impact should be balanced against the difficulty in conceiving a novel concept.

Research Status

Research required.


We would also like to invite UK researchers and industry stakeholders within ORE to submit links to research projects, both past and present, for inclusion within the landscape.

Therefore, if you have a UK-based research project within an area of ORE that you feel is relevant to a specific research theme or challenge within the Research Landscape, click HERE to submit your research project to the research landscape
