The Hydrogen TCP aims to accelerate hydrogen implementation and widespread utilisation to optimise environmental protection, improve energy security and promote economic development internationally.

Executive Committee

Large underground pipes for hydrogen

The Hydrogen TCP envisions a hydrogen future on a clean sustainable energy supply that plays a key role in all sectors of the global economy. With a 40+ year operating history and significant accomplishments to its credit, the Hydrogen TCP is the premier global resource for technical expertise in hydrogen R,D&D. The Bioenergy TCP Executive Committee Representatives for Ireland are Dr. Emer Dennehy (SEAI) and Ms Ann-Marie Colbert (SEAI).

Emer Dennehy

Programme Manager - Offshore

Dr Emer Dennehy is Programme Manager for Offshore Renewable Energy with the Sustainable Energy Authority of Ireland. Initially qualifying as an electronic engineer, Emer now holds both a Masters and PhD in Energy Engineering from University College Cork, Ireland. Emer has nearly 15 years of experience in analysing energy systems both at national and international levels, through energy statistics analysis and senior modelling specialist roles for Sustainable Energy Authority of Ireland, as well as in the Energy Technology Perspectives Division in the International Energy Agency (IEA) from 2013 to 2016.




Ann-Marie Colbert

Programme Manager - International Energy Research

Ann-Marie is the Programme Manager for International Energy Research at the Sustainable Energy Authority of Ireland (SEAI). As part of this role, Ann-Marie acts as a National Contact Point for Horizon Europe Cluster 5 Energy. Ann-Marie holds a degree and masters in business, as well as a Diploma in Management Practice and a Postgraduate Diploma in Economic Policy. She has extensive experience of working in the energy sector, and of both national and EU funding mechanisms. Ann-Marie currently manages engagement in international energy research activity through Horizon Europe Cluster 5 and the International Energy Agency Technology Collaboration Programmes (TCPs).

Task 40 — Energy Storage and Conversion Based on Hydrogen

Task 40 addresses energy storage and conversion based on hydrogen by developing reversible or regenerative hydrogen storage materials. In these materials, the quantitative targets for hydrogen storage capacities and operation temperatures depend strongly on the different application objectives, e.g. mobile systems, transport and distribution, or stationary storage systems. The fundamental understanding of hydrogen storage mechanisms is the key for a breakthrough in the development of materials with improved properties.

The Representatives for Task 40 are Mr. Pau Farras Costa (University of Galway) and Ms. Mary Pryce (Dublin City University).

Task 42 — Underground Hydrogen Storage

This Task focuses on research & innovation challenges to prove and demonstrate the technical, economic, and societal viability of underground hydrogen storage (UHS). This concerns storage options in porous reservoirs, salt caverns, and other manmade spaces. The technical viability of hydrogen storage in porous reservoirs is relatively less developed, and as such, it is still under more fundamental scientific and technological investigations.

The Representatives for Task 42 are Dr. Zili Li (University College Cork) and Mr James Carton (Dublin City University).
