This project will develop the novel concept of 5th generation district heating networks in Scotland, which utilise multiple low carbon heating sources, such as heat from waste water, river water, data centre, off-peak electricity. The project will focus on developing numerical models and tools for system simulations and optimisation. Power-to-heat concept and thermal energy storage technologies will be introduced to utilise the off-peak wind power generation. The interactions between such heat network with the grid will be then investigated. The project outcomes would strongly support the Development of 5th Generation District Heating and Cooling (5GDHC) Infrastructure and Ambient Loop which will adopt various technologies for heating and cooling demands. The project will demonstrate how efficiency can be maximised to reduce energy losses.
