107137 - Analysis on Economy and Carbon Emission of a Carbon Neutralized Integrated Energy System Supplied With Different Energy 

Integrated energy system (IES) can effectively realize the complementary advantages of various energy sources and improve the energy utilization rate. This paper takes an IES as the research object and establishes an IES mathematical model, which takes the minimum daily operation costs as the objective function and considers the carbon neutral target. The results show that only the system uses renewable energy fuel can achieve lower carbon emissions than using natural gas. For the IES, the best energy carrier for achieving carbon neutrality is renewable energy hydrogen. When the IES uses natural gas and renewable energy fuel mixture, under the same CH₄ proportion, system has the lowest carbon emission using H₂+CH₄ mixture and has the lowest operation cost using NH₃+CH₄ mixture. In the IES considering distributed renewable energy utilization, the system can achieve the lowest carbon emissions than using all renewable energy for fuel production or for power supply if 93% renewable energy output is used for hydrogen/ammonia production and 7% renewable energy output is used for power supply. In the IES considering renewable energy utilization, reducing carbon capture equipment energy consumption can achieve better economic and environmental benefits than improving renewable energy hydrogen production efficiency.
