Fionn Rogan
Research Fellow
UCC Energy Transition, Climate Action Energy Policy & Modelling


Fionn is a Senior Research Fellow in MaREI and is located in the Environmental Research Institute in UCC. Fionn is interested in energy systems modelling, climate policy pathways, philosophy of technology, and energy innovation. Fionn is an expert developer of the LEAP Ireland energy system model and an experienced user of the Irish TIMES energy system model.

Current Activities

Fionn currently leads the CAPACITY project which is developing energy system models to support climate action policy making in Ireland.


Fionn has also worked on projects examining the decarbonisation opportunities for Ireland. He is formerly a climate technology fellow supported by the EPA, where he examined how an innovation systems approach can help realise climate technology opportunities in Ireland. For his PhD, Fionn developed and used techno-economic energy systems models for long-term energy systems evaluation.

He has lectured on many energy systems modelling and sustainable energy modules in UCC and has published in key energy and transport research journals. In addition to academic work, Fionn has extensive industry experience, where he worked in the semi-conductor industry for four years. Fionn has a B.Eng. (Industrial Engineering and Information Systems) from NUI Galway, an MEngSc (Sustainable Energy) from UCC, and a PhD (Energy efficiency evaluation and energy systems modelling) from UCC.

Feature Project

CAPACITY (Climate Action Pathways & Absorptive Capacity)

The CAPACITY project will further develop and update tools to facilitate insights and robust decision making about the appropriate long-term decarbonisation pathway for Ireland.
