Juxtaposing bulk transfer of water and renewable energy storage
Bulk transfer of water should be a key factor in the provision of resilience in water supply, helping to address population and climate change driven water scarcity in the South East by taking advantage of existing water resources in the north and north west of the country, with these likely to become more viable under wetter climate change scenarios.
This research will take the novel approach of evaluating and modelling the potential to achieve both bulk transfer and storage of renewable energies to help meet the impending supply demand crisis in the energy sector. This will be done by considering options such as multistage pump storage across different routes with short duration operation driven by energy supply and demand needs, but providing long term bulk movement of water. The inefficiencies of pump storage and costs of bulk transfer can be offset by the value associated with peak energy demands. Thus the concept offers the potential to transform previous assessment of bulk transfer schemes that have frequently found energy costs to be prohibitive. Further the project will seek to explore transfer of treated or semi treated water directly to impounding reservoirs such that the environmental concerns of inter catchment transfer (such as from the Severn to the Thames) are mitigated. A final novel aspect to be considered will be the utilisation of ‘dark infrastructure’, that which already exists but could be exploited or connected to transform its use, for example Severn Trent and Yorkshire Water have strategic transfer grids within their monopoly regions. The project will focus on technical feasibility, taking systems mapping and technology performance modelling approaches to unlock new transformative potential for both water and energy systems.
