Dr Enass Abo-Hamed is working on one of the most challenging and intriguing energy problems today: efficiently and safely storing clean energy. While on a trip to Africa when studying for her PhD, Enass realised how much of a luxury electricity was, with some hospitals only receiving power for part of the day, and people rushing to do all their cooking and reading at home while the electricity was still on. So, at the age of just 28, she co-founded a business, H2GO, to develop a hydrogen battery that would be able to store clean and renewable energy in countries without an electrical grid. We caught up at her lab in London to talk about the future of energy, and why science and not guilt is the true path through the climate change crisis.
