Scientists and engineers from Loughborough University and EnerHy are leading the way in showcasing green hydrogen's potential at the Festival of Tomorrow in Swindon. This event, taking place from 12 – 23 February, highlights how green hydrogen can be generated, stored, and utilized for clean power. The activities include showcasing the world’s first full-scale lead-acid battery-electrolyser cell for sustainable hydrogen production, engaging in a fun game to catch green hydrogen molecules, and demonstrating how fuel cells convert hydrogen into electricity to power vehicles with water as the only emission. The Festival's theme, 'Our Future Earth', emphasizes sustainability and features engaging exhibits like Luke Jerram’s Gaia artwork. Public engagement is a key focus, with Professor Dan Parsons stressing its importance in educating and inspiring support for a Net Zero future. The collaboration between Loughborough University, UKRI, Cranfield University, the University of Strathclyde, and industry partners like BOC, Cadent, ESB, and JLR showcases a commitment to advancing hydrogen research. The event aims to accelerate the affordability, scalability, and sustainability of hydrogen while inspiring the next generation of scientists and engineers.
