Integrated Energy System for Power Generation, Energy Storage, and Peak Regulation

Strategic Insights

— 1 min read

Researchers at Shandong University in Jinan, People's Republic of China, have proposed an integrated energy system that encompasses power generation, energy storage, and peak shaving functionalities. The system utilizes heat from solar energy and renewable electricity to produce methanol, which serves as a means of energy storage. The system also captures CO2 and repurposes it as raw material for methanol synthesis, making it a closed-loop conversion of 'solar, heat, electricity, hydrogen, and carbon.'

Key Takeaways:

  • The integrated energy system achieves energy utilization efficiencies of 26.3% at 100% load of full system and 37.9% at 30% load of GTCC.
  • The system exhibits exergy efficiencies of 34.8% and 49.5% at 100% load of full system and 30% load of GTCC, respectively.
  • The investment payback period for this system is 15.8 years.
  • The system showcases significant advantages such as zero carbon emissions and a green, clean profile, indicating strong development prospects.
  • The research has been peer-reviewed and concluded that it can offer valuable guidance and suggestions for constructing new systems in the future energy sector.

Statistics:

  • 15 MW: The integrated energy system is designed to discharge electrical power at a capacity of 15 MW.
  • 26.3%: Energy utilization efficiency at 100% load of full system.
  • 37.9%: Energy utilization efficiency at 30% load of GTCC.
  • 34.8%: Exergy efficiency at 100% load of full system.
  • 49.5%: Exergy efficiency at 30% load of GTCC.
  • 15.8 years: Investment payback period for the integrated energy system.
