QUOTIENT “Quantification, Optimization and Environmental Impacts of Marine Renewable Energy” is a Research Cluster within the Sêr Cymru National Research Network for Low Carbon, Energy and Environment (NRN-LCEE). The Cluster is led by Simon Neill, School of Ocean Sciences, Bangor University, and has partners at Swansea University (Ian Masters), Cardiff University (Tim O’Doherty), and the University of South Wales (Daphne O’Doherty).

The QUOTIENT Research Cluster will produce scientific research that will examine how wave and tidal energy resources interact with one-another, over a variety of spatial and temporal scales, from centimetres to kilometres and from sub-second to multi-decadal. Research within the cluster will determine how we can best manage marine renewable energy extraction, for multiple resource types, for future energy extraction scenarios, informing future energy policy and investment in the electricity network. The cluster will also investigate how feedbacks between energy extraction and the resource influence dynamical processes that are driven by the resource, such as sediment transport and the maintenance of beaches and offshore sand banks.

In particular, this research will determine how such impacts compare to natural variability, and how these impacts could actually be used to our benefit, for example by providing a secondary form of coastal protection from the impact of storm waves via the exciting possibility of geoengineering. By applying a range of high resolution 3-dimensional solutions on supercomputers over a variety of timescales from sub-second (turbulent) to decadal (including climate change), and simulating across a vast range of scales from individual turbines to the edge of the continental shelf, validated and parameterised by field observations and laboratory experiments, the cluster will result in world-leading environmental research that is of direct relevance to industry and policy.
