Multi-stage Decarbonization Planning for Receiving-end Power Systems Considering Thermal Power Generation with Hydrogen-Ammonia Cofiring
Utilizing renewable energy sources such as wind and photovoltaic to identify cost-effective decarbonization pathways for coastal receiving-end power systems is one of the core challenges in achieving the goals of “carbon emission peak and carbon neutrality” of China. By analyzing the techno-economic differences between hydrogen-ammonia storage and existing energy storage technologies (such as electrochemical and compressed air energy storage)
a multi-year expansion planning model for power systems incorporating cofiring coupled hydrogen-ammonia energy storage under temporal decarbonization constraints is established
and the techno-economic feasibility of achieving low-cost decarbonization within the power system is explored. The actual data are selected from Guangdong power grid of China for case study. The results demonstrate that
under increasingly stringent carbon reduction constraints
it is necessary to progressively achieve decarbonization targets through technical pathways
such as the newly added wind and photovoltaic storage
the transition from coal to gas in thermal power planning modes
and the newly added hydrogen-ammonia energy storage (including hydrogen cofiring in gas turbines
ammonia cofiring in coal-fired plants
and ammonia decomposition). Compared with a decarbonization mode relying solely on lithium-ion battery peak shaving
the introduction of cofiring coupled hydrogen-ammonia energy storage technology can avoid overloading excessive wind and photovoltaic storage capacity
thus significantly reducing the wind and photovoltaic curtailment rates. This approach not only achieves intensive resource utilization
but also further reduces the decarbonization cost of hydrogen-ammonia energy storage through the reuse of existing thermal power generation infrastructure. Therefore
the use of hydrogen-ammonia energy storage technology for power system decarbonization presents a scalable and economically feasible decarbonization pathway.
