Chemical engineer Peng Peng is helping develop a 100% renewable energy grid by investigating new materials for storing hydrogen gas, which can be used like a battery to stash power generated from solar and wind farms. Peng uses computer models to study how lab-scale material prototypes would perform at the industrial scale, and how much they would cost – accelerating the green hydrogen movement from discovery to deployment.

In this episode, we speak to a policy leader and a researcher about the history of piggy-banking power to spend it later, and how this field is evolving to help us prevent extreme weather-related blackouts, adopt more renewable energy, and build bigger, better, more environmentally responsible batteries.
