Hydrogen energy is becoming more and more blooming because of its diversified sources, eco-friendly and green, easy storage and transportation, high-efficient utilization, etc. The use of hydrogen as an energy carrier is expected to grow over the next decades. Hydrogen, like electricity, is a secondary energy. Hydrogen production is the foundation for all kinds of applications. Based on the resources situation in China, potential of hydrogen production is analysed. China has a large potential of hydrogen production from coal, which is about 2.438 billion tons. Potential of hydrogen production from natural gas is less than that from coal, which is about 501 million tons. According to the average consumption of methanol per year, potential of hydrogen production from methanol is about 690, 000 tons per year. Potential of hydrogen production from industrial gas (coking, petrochemical and chlor-alkali industries) is about 866, 400 tons per year. Potential of hydrogen production from abandoned renewable energy power is about 1798.2 million tons per year. Distribution of resources in China differs among provinces. The deployment of hydrogen industry should pay attention to local hydrogen production potential. A green hydrogen production method, such as water electrolysis by renewable energy power, is a promising and environmental friendly way.

AbstractAs a promising substitute for fossil fuels, hydrogen has emerged as a clean and renewable energy. A key challenge is the efficient production of hydrogen to meet the commercial-scale demand of hydrogen. Water splitting electrolysis is a promising pathway to achieve the efficient hydrogen production in terms of energy conversion and storage in which catalysis or electrocatalysis plays a critical role. The development of active, stable, and low-cost catalysts or electrocatalysts is an essential prerequisite for achieving the desired electrocatalytic hydrogen production from water splitting for practical use, which constitutes the central focus of this review. It will start with an introduction of the water splitting performance evaluation of various electrocatalysts in terms of activity, stability, and efficiency. This will be followed by outlining current knowledge on the two half-cell reactions, hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), in terms of reaction mechanisms in alkaline and acidic media. Recent advances in the design and preparation of nanostructured noble-metal and non-noble metal-based electrocatalysts will be discussed. New strategies and insights in exploring the synergistic structure, morphology, composition, and active sites of the nanostructured electrocatalysts for increasing the electrocatalytic activity and stability in HER and OER will be highlighted. Finally, future challenges and perspectives in the design of active and robust electrocatalysts for HER and OER towards efficient production of hydrogen from water splitting electrolysis will also be outlined.
