(Climate Now) Hydrogen is uniquely qualified as a storage of clean energy because it is abundant – the most abundant element in the universe – and it can be produced using renewable energy. When consumed in a fuel cell, its only byproduct is water, making it ideal for our net-zero emissions future. Hydrogen, however, also comes with unique challenges, such as high inefficiency during production and transportation difficulties. Climate Now host Dr. Ozak Esu details the benefits and trade-offs of hydrogen with the help of Duke University Professor of Chemistry Dr. Ben Wiley. Running Time: 13 mins
