Beginning with the current situation of China's energy consumption,the progress in carbon dioxide emission control is introduced.The shortcomings of hydropower,nuclear power,solar and wind power as majority energy are analyzed,and the characteristics of hydrogen energy are expounded.From both China's domestic and international perspectives,it emphasizes the opportunities of hydrogen energy development and the urgency of developing alternative to fossil fuels.Using a case-study approach,the main cost components of hydrogen production from electrolytic water and the sensitivity of the cost impact of different electricity prices and different utilization hours are analyzed,with comparing the cost changes of hydrogen production from fossil energy sources with the addition of"carbon capture and storage"technology.The solutions such as reducing the cost of hydrogen production from green power,opening up new channels for hydrogen production,breaking the key technology,expanding the application of hydrogen energy etc.In conclusion,using policy support as the driving force,multi-party linkage to accelerate pilot demonstrations as the method,as well as taking the combination of"green power+energy storage+hydrogen production"to compensate for the shortcomings of clean energy is the preferred comprehensive path to achieve the"carbon dioxide emission peaking and carbon neutrality"goal and promote green development.
