Paper on GreenSCIES wins Lightfoot medal

A paper produced by GreenSCIES researchers working at London South Bank University (LSBU) has been awarded the prestigious Kenneth Lightfoot medal of the Institute of Refrigeration (IOR). This medal is presented to the best paper in the previous IOR evening papers session and the winner is chosen by vote of the IOR membership. The award was announced at a virtual online event that took place on 24 June 2021.
The paper, titled “GreenSCIES – Green Smart Community Integrated Energy Systems – Integration with Data Centres”, was co-authored by Catarina Marques, Robert Tozer, Akos Revesz, Chris Dunham, Phil Jones, Rodrigo Matabuena, Carole Bond, Henrique Lagoeiro, Matt Wegner, Gareth Davies, and Graeme Maidment from LSBU, with input from across the project.
Professor Graeme Maidment, project director said “This is fantastic news, as it will help the wider community understand the importance of usefully capturing waste heat from sources such as data centre. Well done to Cat and Robert for leading this.”
The paper explains how the GreenSCIES project aims to deliver low carbon, affordable energy through a novel smart energy system that connects flexible electricity demands such as heat pumps and electric vehicles to intermittent renewable energy sources such as solar power. The results of the study show the feasibility of a 5th generation district mobility, power and heat network in the London Borough of Islington.
The smart network facilitates the transition to electric vehicles and vehicle-to-grid supply to make the most of intermittent renewable energy and ensure end-users always get the best tariff. Heating and cooling are provided by heat pumps in buildings connected to a local network, which integrates thermal energy storage and waste heat recovered from local datacentres. Artificial intelligence underpins the system optimisation and demand side response. Low carbon heating and cooling is achieved by sharing heat between buildings and by shifting the timing of their demand to off-peak cheaper electricity; this requires a sophisticated control system and thermal energy storage.
The feasibility study also worked with key stakeholders to understand the views of end-users and others in the supply chain. The role of key thermal energy providers such as Transport for London and Data Centres is fundamental. The preliminary results indicate that the smart network can deliver up to 25% reduction on energy bills and 80% CO2 savings compared to a baseline scenario with gas boilers, chillers and grid electricity. As the electricity grid decarbonises further it is forecasted that the network will tend to net zero carbon before 2050. The GreenSCIES concept is suitable to be replicated throughout the country and has the potential to become a world-leading example.
