In a groundbreaking study published in *Power Construction*, researchers from Northeast Electric Power University in China have proposed a novel approach to optimize the operation of integrated energy systems, focusing on ammonia refrigeration and ammonia blending in thermal power plants. The research, led by Dr. Chu Zhuang and Dr. Yuan Jixin, aims to address the dual carbon challenge—reducing both carbon emissions and costs—while maximizing the utility of ammonia throughout its lifecycle.
The study introduces a joint model that combines ammonia refrigeration with thermal power units, creating a symbiotic relationship that enhances overall system efficiency. “By linking the endothermic process of converting liquid ammonia into pure ammonia with ammonia refrigeration, we can utilize the cooling energy in a cascade manner,” explains Dr. Chu. This innovative approach not only reduces system costs but also significantly cuts carbon emissions, making it a promising solution for the energy sector.
One of the key aspects of the research is the exploration of economic and low-carbon operation in high volatility wind power scenarios. The entire electric to ammonia conversion system is powered by renewable energy, specifically wind power, which is known for its variability. The study proposes a stepped carbon trading model to reasonably constrain the carbon emissions of the system, ensuring that the benefits of renewable energy are maximized without compromising environmental goals.
The researchers also analyzed different scheduling strategies under varying wind power penetration rates. They found that their proposed strategy could reasonably allocate the output of each unit, absorb waste air volume, and improve the economic efficiency of the integrated energy system operation. “The combination of ammonia gas as a refrigerant and fuel with thermal power units can help traditional thermal power plants overcome the carbon locking dilemma,” says Dr. Yuan.
The implications of this research are far-reaching for the energy sector. By optimizing the use of ammonia in both refrigeration and power generation, the study paves the way for more sustainable and economically viable energy solutions. The integration of renewable energy sources like wind power further enhances the environmental benefits, making it a win-win scenario for both industry and the planet.
As the world continues to grapple with the challenges of climate change and the need for sustainable energy, this research offers a glimpse into the future of integrated energy systems. The findings could shape future developments in the field, driving innovation and fostering a more sustainable energy landscape. With the publication of this study in *Power Construction*, the energy sector has a new tool in its arsenal to combat carbon emissions and optimize system performance.
