    Title: The Energy Transition: Green hydrogen, fuel cells and carbon capture

    Abstract: The transition to a low carbon economy to avoid the climate change requires green hydrogen, fuel cells and carbon capture. Green hydrogen is necessary for the decarbonization of the sectors of our economy that are inaccessible by renewable electrons, such as ammonia synthesis. For low temperature electrolzyers for green hydrogen generation and fuel cells for transportation, polymer electrolytes play a central role in controlling their cost, performance, and durability, and consequently their economic viability. In this presentation, I will focus on our work on hydroxide exchange membrane electrolyzers (HEMELs) and fuel cells (HEMFCs) that do not require precious metal catalysts and expensive stack components. I will also show our recent work on carbon capture using hydroxide exchange membranes.
