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 Denis Neary (SEAI) and Ms Ann-Marie Colbert (SEAI).

Denis Neary

Senior Offshore Technical Specialist

Denis is the Senior Technical Specialist for the Offshore Renewable Energy team at the Sustainable Energy Authority of Ireland (SEAI). As part of this role, Denis acts as a National Contact Point for the Hydrogen TCP. Denis holds a degree in Sustainable Energy Engineering and a masters in Business and Entrepreneurism. He has extensive experience of working in the onshore and offshore energy sector, construction industry as well as the development of sustainable energy government support schemes. Denis is currently working on the construction and operation of the Atlantic Marine Energy Test Site and the SEAI’s Hydrogen TCP participation.



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.

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).

Task 45 — Renewable Hydrogen Production

The new “Renewable Hydrogen production” (RE-H2) task aims at monitoring the evolution and supporting the visibility of a wide range of renewable hydrogen production technologies as well as providing indications for their technological assessment. The idea is to provide clear and brief updates on the status of different pathways to green hydrogen production, from water-splitting (electrolysis, thermochemical, hybrid) to the conversion of biomass/waste-derived feedstock (biological, thermochemical).

The Representatives for Task 42 are Rory Monaghan (University of Galway) and Muireann Lynch (Economic and Social Research Institute).
