The article talks about challenges faced while trying to storage and produce hydrogen for a sustainable and clean future energy. It talks about extraction of hydrogen from water through electrolysis being expensive and uncompetitive with production from hydro-carbons. However, the challenge was resolved by Lifshitz from Technion, Haifa, Israel and Kang et al from Soochow University, Suzhou, China, by designing a carbon nanodotcarbon nitride (Cdots-C3N4).
