22 Nov 2017 | The Data Centres Ireland conference (22nd-23rd November 2017) will be of great interest to industry, policy and researchers with an interest in data centres on a micro and macro level. Our presentation (on Thursday 23rd November) titled "An Analysis of Emerging Trends and Constraints in the Irish Data Centre Market" will look at how liquid cooling could help alleviate increasing demands on the Irish energy system.
In 2018, data centres in Ireland consumed 12% of the national average electricity supply in Ireland, a figure which is expected to double by 2027. Much of this electricity is consumed by computing equipment which generates heat. Currently this waste heat is considered a negative externality, however, novel emerging technologies offer the potential to convert this waste heat into uses such as space and water heating and to more actively manage the electricity demand.
This project is investigating the economic costs and benefits of utilising the waste heat and options for dynamic management of electricity demand for data centres.
This research is part of ESIPP, the wider Energy Systems Integration Partnership Programme. Funded by Science Foundation Ireland (SFI), ESIPP brings together a multidisciplinary, multi-institutional research team in Ireland with expertise in electricity, gas, water and data, with the relevant industry partners to focus on building the human capacity. ESIPP involves 23 academics from 7 institutions across Ireland.

Postdoctoral Researcher - Mechanical Engineering
Dr. Sara Battaglioli is a postdoctoral research fellow working on the optimisation of hybrid cooled data centre servers, seeking to maximise the potential for energy recuperation from these systems through retrofitting or new server architecture designs.
Sara has carried out her PhD studies in the Department of Mechanical & Manufacturing Engineering at Trinity College Dublin on numerical modelling of solidification, and joined ESIPP after graduating in 2018.
Postdoctoral Researcher - Mechanical Engineering
Dr. Assel Sakanova is a postdoctoral research fellow working on server-level and rack-level thermal management strategies for next generation hybrid (air/liquid) cooled servers for data centres.
Assel has carried out her PhD studies in Electrical & Electronic Engineering at Nanyang Technological University (NTU), Singapore on cooling of power electronics. After graduating in 2016, she worked at the Rolls Royce Corporate Lab in NTU as research fellow.
PhD student - Mechanical Engineering
Jaakko is currently pursuing a PhD under the supervision of Dr. Tim Persoons at Trinity College Dublin. He received his Master’s degree from Trinity College Dublin in 2015.
He is currently working on novel liquid cooled heatsink solutions using unsteady flow and surface structuring, for next generation servers in sustainable data centres. The main target application is thermal management and heat recuperation from CPU packages in rack-mounted volume servers for data centres.
This work aims to develop an adaptive liquid cooling solution to account for spatial and temporal heat load variations using a range of techniques, such as: Computational fluid dynamics; Advanced experimental flow visualisation; Velocity field quantification and temperature and heat transfer rate measurements.
PhD student - Economics
Bryan is currently pursuing a PhD in Economics under the supervision of Prof. Eleanor Denny at Trinity College Dublin. His research is focused on economic aspects relating to data centers.
He is currently investigating how different data center cooling techniques could be used to provide additional economic benefit across a number of areas such as: Reducing the level of data center demand on the electricity grid; Repurposing waste heat for district heating and how efficiencies in data center energy consumption could help countries work towards meeting emission reduction targets.
Prior to this, Bryan worked at the Economic and Social Research Institute as a Research Assistant from August 2014-2016 in the Economic Analysis division. He holds a BA in Finance & Economics and an MA in Economics from NUI Maynooth.
