Abstract: Based on the analysis on energy efficiency, three waste discharges, and driving force for relevant industries of hydrogen manufactures from fossil and renewable energies and its utilization processes, it is recognized that hydrogen energy is the high efficiency way to utilize the primary energy sources and is the cleanest secondary energy. The development of the hydrogen energy will drive industrial innovation and industrial transformation. The risks in the development and applications of hydrogen energy can be controlled and the key is to develop a complete and systematic technical support. The technologies and equipments for developing and utilizing hydrogen energy in China are suggested.

Key words: Hydrogen energy, development, application, energy efficiency, safety and risk
