The Festival of Tomorrow in Swindon, organized by Loughborough University and EnerHy, focuses on green hydrogen technology for a Net Zero future. This event showcases innovations in generating, storing, and utilizing green hydrogen for clean power. Activities include unveiling the world's first full-scale lead-acid battery-electrolyser cell for sustainable hydrogen production, interactive competitions like capturing green hydrogen molecules to win a model car, and demonstrations of how fuel cells convert hydrogen into electricity with water as the only emission. The festival theme, 'Our Future Earth,' promotes public engagement and features educational programs and exhibits. Loughborough University's partnership with UKRI, Cranfield University, and industry collaborators like BOC, Cadent, ESB, and JLR is crucial for advancing hydrogen research. The goal is to accelerate the affordability, scalability, and sustainability of hydrogen through cross-cutting research. This initiative aims to inspire the next generation of scientists and engineers and drive the transition towards a cleaner, greener future.
