Dr. Paul McCormack, leading Hydrogen Ireland, envisions a new industrial revolution in Ireland powered by green hydrogen to create a sustainable economy. By positioning Ireland as a testing ground for green hydrogen systems, McCormack aims to prove the viability of this clean energy source and export the knowledge globally. He emphasizes the importance of system coupling to integrate renewable energy sources efficiently. Although challenges exist, such as high energy costs and competition within the EU market, Ireland's collaborative approach with policymakers and energy companies is driving progress. Events like the World Hydrogen Technologies Convention highlight Ireland's potential in clean energy. Dr. James Carton from Dublin City University supports the shift towards green hydrogen as a critical solution for Ireland's renewable energy storage needs. The article emphasizes the need for Ireland to capitalize on this opportunity and not miss out on a significant energy transition. Despite acknowledging the journey ahead, the sentiment is positive, focusing on the potential for Ireland to lead in sustainable energy innovation.
