Abstract
Abstract Hydrogen has been always the hot topic, which drives a lot of researchers to study and explore hydrogen‐related projects and fields. The first subfield is hydrogen production with green and cost‐effective means. Some methods have been intensively used for high‐efficient hydrogen production, i.e., catalytic chemical hydrogen generation, electrocatalytic hydrogen evolution, photocatalytic hydrogen evolution, photo‐electrocatalytic hydrogen evolution. Most of them are driven by various catalysts. Moreover, the hydrogen storage is also an important question, which is also a present research hot topic, although the history is long with several decades. Hydrogen fuel cells have also obtained great attention due to the zero emissions. The related research mainly focuses on the cell systems and electrocatalysts used. Under this background, we invite some excellent research groups to write this progress on hydrogen from production to utilizations. Finally, we believe that this roadmap on hydrogen can give some useful guidance in future research.
