基于零碳排放模式的氢气储能应用场景展望

Perspective on Application Scenario of Hydrogen Energy Storage Based on Zero Carbon Emission

氢能是重要的可再生无碳能源,被视为21世纪最具潜力的能量载体,氢气储能可以有效解决可再生能源消纳,平抑电网峰谷差。我国是全球最大的能源消费国和CO 2排放国,基于“碳达峰”、“碳中和”,提出“零碳排放”模式的氢气储能应用场景。通过制氢、储运、终端应用等3个环节,结合能量转换效率、制氢成本、氢气储能技术、氢气输送、盈利模式和生态影响等方面,就氢气储能应用场景的发展趋势进行了展望。研究发现,储能应用尚存许多技术瓶颈,各环节还有许多问题有待解决。展望未来,建议从技术创新入手,提升氢气储能技术的能量转换效率;降低投资成本,助力氢气储能技术大规模商业化应用。

Hydrogen energy is an important renewable carbon-free energy,which regarded as the most ultimate energy carrier in the 21st century.Hydrogen energy storage can effectively solve the accommodation of renewable energy and stabilize the peak-valley of power grid.China is the largest energy consumer and CO 2 emitter in the world.The application scenario of hydrogen energy storage for the model of zero carbon emission was proposed based on the carbon peaking&carbon neutralization.Through three links of hydrogen production,storage&transportation,and terminal application,the development trend of hydrogen energy storage application scenario was prospected combined with energy conversion efficiency,hydrogen production cost,hydrogen energy storage technology,hydrogen transportation,profit model and ecological impact.It is founded that there are still many technical weaknesses in energy storage application,and there are still many problems to be solved in each link.Looking forward to the future,it is suggested to improve the energy conversion efficiency of hydrogen energy storage technology with technological innovation,and promote the large-scale commercial application with cost parity.
