Abstract: Hydrogen is an excellent renewable energy carrier and is also considered as an important contributor for the future carbon neutrality of the data center industry.Taking energy saving and carbon reduction as the main aim,this article introduces the hydrogen energy application significance,prospect and relevant research status on data center area,and analyzes the impact of hydrogen production,storage and utilizations of the hydrogen energy industry chain on the application of hydrogen energy in data center. Finally,this paper expounds the hydrogen energy conceptual scheme in different application scenarios such as backup power supply,centralized power supply and distributed power supply in data center,and analyzes the technical characteristic and development prospect of each application scenario.
