Low carbon molecules will be needed as the world decarbonises. Hydrogen and its carriers will play a key role in this context. The presentation will discuss the role that hydrogen can play, both as a low carbon fuel and chemical feedstock, as well as its potential role in long term energy storage, along with some of the key technologies, with particular focus on electrochemical technologies such and electrolysers and fuel cells. The speaker will also draw on his 40 years experience of working in this field to make some personal reflections on his journey through electrochemical science, engineering and technology, across industry, academia and start-ups.
