In the pursuit of a greener future, researchers are constantly exploring innovative ways to integrate renewable energy sources and reduce carbon emissions. A recent study published in the journal *Power System Technology* offers a promising approach to achieving these goals by optimizing the operation of integrated energy systems (IES). The research, led by YAN Wenwen from the School of Electrical and New Energy at China Three Gorges University, focuses on the synergistic operation of advanced adiabatic compressed air energy storage (AA-CAES) plants equipped with solar thermal modules and power-to-gas (P2G) systems coupled with carbon capture and storage (CCS).
The study introduces a novel low-carbon optimal scheduling model for IES, which aims to minimize both net carbon emissions and comprehensive costs. By integrating solar thermal modules with AA-CAES plants, the researchers have developed a coupling model that enhances the overall efficiency and sustainability of the energy system. “The integration of solar thermal modules with AA-CAES plants allows for more efficient energy storage and utilization, significantly reducing the carbon footprint of the system,” explains YAN Wenwen.
One of the key innovations in this research is the incorporation of a P2G-CCS system, which converts excess renewable energy into synthetic gas and captures the resulting carbon emissions. This process not only reduces greenhouse gas emissions but also provides a valuable resource for various industrial applications. The study proposes an operation strategy for a combined wind-light-carbon capture power plant, which leverages carbon capture equipment and a carbon trading model to further optimize the system’s performance.
The findings of this research have significant implications for the energy sector, particularly in the context of the “double carbon” target, which aims to peak carbon emissions by 2030 and achieve carbon neutrality by 2060. By demonstrating the potential of AA-CAES plants with solar thermal modules and P2G-CCS systems to reduce both costs and carbon emissions, this study provides a roadmap for the future development of low-carbon energy systems.
“The synergistic operation of AA-CAES energy storage plants containing solar thermal modules and P2G-CCS can further reduce the total cost and carbon emission,” states YAN Wenwen. This research not only advances our understanding of integrated energy systems but also paves the way for more sustainable and economically viable energy solutions.
As the energy sector continues to evolve, the insights gained from this study will be invaluable in shaping future developments and policies. By embracing innovative technologies and strategies, we can move closer to achieving a low-carbon future and securing a sustainable energy supply for generations to come.
