Abstract:

Due to its remarkable advantages, the ammonia decomposition hydrogen production and energy storage system are crucial for advancing future dual carbon goals and energy system construction. Herein, the operating characteristics of an ammonia decomposition tubular filled-bed reactor under electrical heating are simulated and incorporated into a power system, considering uncertainties on both sides of the source load. The effects of increased capacity of the installed ammonia decomposition system on the performance indicators of the power system, such as electricity costs, carbon emissions per kWh, share of new energy generation, utilization rate of new energy, and daily hydrogen production, are analyzed under three different power system installation compositions. The results show that the ammonia decomposition system can effectively improve the consumption level of new energy generation. The maximum capacity of the ammonia decomposition system can increase the utilization rate of new energy by 5.5%—62.4% and the share of new energy generation by 14.2%—160.8% under the three compositions; the resulting carbon emissions from electricity generation are reduced by 0.9%—22.8%, and the cost of electricity generation is increased by 7.6%—34.5%. For the three compositions, the daily hydrogen production reaches 39,000, 104,000, and 171,000 tons, respectively. The results of this study can provide a reference for configuring the ammonia decomposition hydrogen storage system in the power system to reduce carbon emission and promote hydrogen energy technology development.
