Irish electricity firm ESB is leading the way in sustainable energy practices by implementing a hydrogen fuel cell power unit at its Dublin head office as part of a demonstration lighthouse project. The GeoPura Hydrogen Power Unit (HPU) is supplying clean power to the office, illustrating the viability of hydrogen-to-electricity technology. With plans for additional trials across Ireland, ESB is contributing to the country's National Hydrogen Strategy, focusing on decarbonizing challenging sectors and enhancing energy security. The project also involves deploying an electrolyser at Aghada Power Station in County Cork to exhibit hydrogen's potential in storing renewable energy. Jim Dollard, ESB's Executive Director, highlights the importance of green hydrogen as a backup energy source during periods of low renewable energy generation. The project aims to be completed by 2025, emphasizing the role of green hydrogen in supporting Net Zero goals and reducing emissions. Alistair Gemmell from GeoPura commends ESB's initiative, stating that the project sets a strong example for transitioning to green hydrogen across various sectors, promoting a sustainable and resilient energy system.
