NexSys: The five Hub Strands


1. Energy Systems: determining how energy systems should evolve to decarbonise.

2. Water: enabling water utilities to adapt to climate and energy targets.

3. Transport: transitioning to decarbonised multi-modal transport and renewable energy use in a fair way.

4. Cities & Communities: enabling communities to become inclusive, resilient and sustainable.

5. Offshore Wind: reducing lifetime cost and risk of offshore wind technologies.

Energy Systems


The purpose of this strand is to determine how energy systems should evolve to have more renewable electricity towards 2030 and subsequently get to the net zero carbon goal by 2050.

Strand Leaders:
Dr Muireann Lynch (ESRI), Assoc. Prof Terence O’Donnell (UCD)
Academics from across NexSys are leading work packages and projects below

Work Packages


ES1 Roadmap – Modelling & Data Coordination Align solutions from all NexSys projects into a roadmap
ES2 Power System Operation, Adequacy, Balancing & Markets Provide solutions and metrics for load balancing on the power system
ES3 Dynamics of Grid Edge and Low-inertia Power Systems Exploring the impact of increased renewable generation on the dynamics of the power system
ES4 The Future Energy Economy Integrate a detailed representation of the energy and electricity systems into an Irish macroeconomic model
ES5 Distribution Networks & Devices Integrate distributed resources into the electrical distribution network
ES6 Gas Networks & Hydrogen (Utilisation, Storage and Transport) Investigate the feasibility of hydrogen as an energy source to deliver net zero
ES7 Finance, Just Transition & Social Justice An empirical assessment of how the Just Transition impacts disadvantaged groups and how it can be financed.
ES8 Future Renewable Energy Sources and Stochastic Scheduling Develop a model to quantify and map renewable generation potential from onshore wind, offshore wind and solar generation out to 2050.

Cities and Communities

The purpose of this strand is to enable local and national authorities, communities and businesses to make their cities inclusive, resilient and sustainable so as to become carbon-neutral cities.


Strand Leader:
Prof Francesco Pilla (UCD)
Academics from across NexSys are leading work packages and projects below

Work Packages


CC1 Sustainable Urban Energy Solutions Deliver innovative solutions across different scales of the urban energy landscape including at scales of the neighbourhood, collectives of large municipal buildings, new and retrofit housing and data centres
CC2 Earth Observation Big Data Deliver algorithm and tool to identify energy that can be reused from different consumer groups
CC3 Energy Flexibility Harnessing at Community, District and City Scale Analyse energy flexibility models to lead communities to net zero
CC4 Energy Justice: addressing transport & residential energy deprivation Poverty-proofing next-generation energy systems by identifying at-risk groups and developing case studies to address energy deprivation


The purpose of this strand is to i) investigate the critical infrastructure, behavioural and policy challenges of transitioning to decarbonised multi-modal transport and renewable energy use in a fair way, and ii) identify tangible evidence-based solutions via engagement and collaboration of key stakeholders tasked with implementing them.


Strand Leader: 

Dr Páraic Carroll (UCD)
Academics from across NexSys are leading work packages and projects below

Work Packages


TR1 Modelling the Transportation network with increased electric vehicle penetration Scenarios Predict future electric vehicle usage patterns to determine energy grid and charging needs
TR2 Travel behaviour shift for short & first and last mile trips Test incentives and develop a model to encourage alternatives to cars (active & micro mobility) for short journeys
TR3 Transition to commercial vehicle electrification policy Develop a database of commercial traffic across Ireland and survey SMEs on attitudes to electric vehicles
TR4 Decarbonising freight traffic sector Review international and European best practices and benchmark the Irish freight fleet against other countries, assess barriers and incentives to improve the energy efficiency of Irish freight
TR5 Greening the Shared On-demand Mobility Fleet Define business models for shared electric vehicles and design a charging network


The purpose of this strand is to enable water utilities adapt to climate and energy targets in the following ways:

  • provide key services in terms of enabling a more efficient energy sector.
  • be more resilient in the context of climate-driven hazards and events.
  • uptake new technology to enable efficient energy use in the water sector.
  • provide for more efficient water management at building and industry scale
  • understand the social and political contexts that are needed to underpin these changes
