Special Issue Information

Dear Colleagues,

Urban cities are facing enormous challenges in meeting their surging energy demand while decreasing carbon emissions. In recent years, low-carbon energy systems attract great attention and are deemed essential means for realizing sustainable cities. However, there are existing obstacles and research gaps in low-carbon energy system management towards sustainable cities. Developing efficient and intelligent solutions for low-carbon energy system management is a complex challenge involving interdisciplinary knowledge and expertise. This special issue, therefore, provides a forum for researchers and scientists to exchange novel research solutions and results to tackle challenges and obstacles in this domain, discuss how smart energy technologies can integrate with urban cities, and formulate policies towards sustainable cities. The detailed topics of interest include, but are not limited to, the following:

  • Urban energy systems
  • Energy storage systems
  • Low-carbon energy technologies
  • Optimization and control techniques
  • Big data, smart energy, and smart cities
  • Energy efficiency and flexibility in buildings
  • Urban energy resilience, policy, and economics
  • Urban energy-water nexus 
  • District heating and CCHP in urban cities
  • Reliability, robustness, fault-tolerance, and self-healing

To leverage temperature glide in evaporation, a transcritcal heat pump using a CO2-based mixture is investigated from a perspective of simultaneous heat and cold energy storage. Coefficient of performance for heating (COPh) and exergy efficiency are used to evaluate system performance. A parametric investigation on the heat pump is conducted, and the coupling behavior of the cycle with thermal energy storage (TES) material is investigated in view of stored exergy of TES. Optimization and comparative studies are carried out among various mixtures. The results reveal that maximum cycle temperature is mainly affected by high pressure and superheating degree, while minimum cycle temperature, as well as cold exergy, is highly dependent on evaporating temperature glide, with little influence from high pressure. The total exergy efficiency can reach up to 60%. The temperature of low temperature TES could reach as low as −32.4 °C for CO2/R601, providing the largest proportion of cold exergy to total exergy, up to 30.1%. Full article
