氢能在我国未来能源系统中的角色定位及“再电气化”路径初探
摘要
在分析制氢、储氢及氢能发电等各环节技术特征及能源转化效率的基础上
结合我国能源禀赋、电力生产特点及发展趋势
分别基于煤炭和可再生能源作为一次能源的应用场景
综合分析了未来氢能的发展应用可行性。研究表明
氢能在我国未来能源和电力发展过程中难以起到支撑作用
"再电气化"是更为现实的技术路径。在此基础上
提出了在未来可再生能源大规模接入的情景下
我国能源电力的发展思路以及"再电气化"需要研究解决的重点课题。
Abstract
The technical characteristics and energy conversion efficiencies of hydrogen production
storage and power generation processes are presented and discussed in this paper. On this basis
combined with China's energy resources
power generation status and developing trends of new power generation technologies
the prospect of hydrogen energy utilization in the future in China is checked on two different application scenarios with coal or renewable energy as the primary energy respectively. It is concluded that the hydrogen energy will not be able to undertake the tough task to support the future energy and power development in China
while the ‘re-electrification' might be the right path. Several key measures are then be presented for addressing the issues which the future power system may face with massive renewable energy being connected into the power grid
and some key points of the research on re-electrification are also suggested.
