Dr. Dan Esposito is an Associate Professor of Chemical Engineering at Columbia and co-founder of sHYp, a startup that uses seawater to produce hydrogen without damaging the environment. Dr. Esposito explains solar fuels, the energy sources his lab studies that are created using the unlimited energy of the sun and can store much more energy than batteries can, but without the climate harm done by petrochemicals. In particular, he’ll talk about why hydrogen is such a promising replacement for fossil fuels for specific applications, such as fuel cells for vehicles or as a precursor material for industrial manufacturing. He’ll also share what he learned on his one-year sabbatical at sHYp, the resources at Columbia he used to get the company going, and the advice he gives his students about how to build successful careers as scientists and entrepreneurs.
