Abstract: This paper aims to explore the feasibility of green ammonia co-firing technology for facilitating the low-carbon transition of backup diesel generator sets in data centers, addressing the challenge of synergistic development between computing power growth and clean energy utilization. By analyzing the development trends of green ammonia energy and the current status of ammonia-diesel blended combustion technology, the study systematically reviews key technical bottlenecks and development potentials, such as the ammonia blending ratio, injection strategy optimization, and engine structural modification. A phased development roadmap is constructed based on economic evaluation and multi-mode operational analysis, while cost-benefit analysis and scenario simulation methods are employed to assess the levelized cost of electricity and carbon reduction benefits under different ammonia blending ratios. The development pathways and corresponding strategies are also analyzed. Results indicate that green ammonia co-firing in backup diesel generator sets offers economic advantages under emergency, mutual assistance, and self-supply operation modes. The levelized cost of electricity decreases with higher ammonia blending ratios and rising carbon trading prices, and is projected to fall below that of traditional diesel generation after 2044. This technology significantly enhances the data center’s capacity for renewable energy integration, reduces carbon emissions, and facilitates the gradual transition of generator sets from a backup power source to a primary power source. This study provides technical and policy support for the synergistic development of "computing power and electric power", demonstrating that green ammonia co-firing is an effective pathway for achieving flexible functional transformation and green upgrading of backup power systems in data centers, with broad application prospects.
