Special Issue Information

Dear Colleagues,

According to the WCED (World Commission on Environment and Development, 1987), sustainability or sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs, and it is a global issue. Generally, sustainability involves economic sustainability, social sustainability, and environmental sustainability, and all of these link to the sustainability of energy/resources, since energy/resource sustainability sets a solid basis for overall sustainability.

An energy system is the basis of the utilization of energy/resources for sustainability, and a sustainable energy system is crucial for our sustainable development as it involves sustainable energy resources, sustainable energy technologies, sustainable energy routes, sustainable energy devices, sustainable energy assessments, sustainable energy policies, etc.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  1. Sustainable energy resources (biomass, wind, solar, etc.);
  2. Sustainable energy technologies;
  3. Sustainable energy routes;
  4. Sustainable energy devices;
  5. Sustainable energy assessments;
  6. Sustainable energy policies;
  7. Energy storage systems;
  8. Other related topics (thermodynamics, heat transfer, hydrodynamics, etc.).

We look forward to receiving your contributions.

Prof. Dr. Yaning Zhang

The efficiency of energy flow and the economic viability of agricultural systems are foundational pillars of sustainable energy management and development. This study applies the energy pyramid framework to evaluate energy flow efficiency and conduct an economic analysis to explore the viability of grape production systems in Takestan County, Qazvin, Iran. Data were collected from 220 grape-growers during the 2020–2021 period. Results indicated that fertilizers and electricity were the major energy inputs, comprising 36.51% and 20.12% of total energy use, respectively. The energy ratio and energy productivity were estimated at 5.81 and 0.49 kg MJ−1. Non-renewable and indirect energy sources constituted 58.16% and 63.29% of the total energy, respectively. Sensitivity analysis revealed that human labor had the highest marginal physical productivity due to the labor-intensive practices of grape production systems. To enhance economic viability, it is recommended to match energy usage to specific operational requirements and maximize system efficiency. These strategies increase labor productivity by streamlining processes and reducing inefficiencies, while optimizing energy inputs to ensure their effective utilization in production activities.

Molten salt energy storage technology shows great potential in a sustainable energy integrated system for its excellent thermal energy storage efficiency and environmental adaptability, and it has received much attention from the academic community. To improve the efficiency of traditional dual-tank heat storage systems, a new distributed single tank thermal storage system with an internal heat source was proposed. The single tank was designed according to API 650 and EN 13445-3:2012 specifications, and the specific data of the storage tank was obtained by combining application examples. The results show the following: (1) the stress of the molten salt storage tank with internal electric heating increases during the heating process, and the peak stress appears at the connection position below the tank body and the electric heater sleeve. (2) The increasing electric heater sleeves lead to the increase in tank stress, and when the number of electric heater sleeves increases from four to eight, the tank stress increases by 24%. (3) The stress of the tank reduces with the increasing axial height of the electric heater sleeve. The stress of the tank is reduced by 8% when the position of the electric heater sleeve is increased from 400 mm to 800 mm. This study can provide some theoretical support for the design and optimization of a single-tank molten salt heat storage system and provide a reference for the design of such storage tanks with a built-in heat source.
