Sustainable Development of Energy, Water and Environmental Systems and Smart Energy Systems

Abstract

This 34th volume of the International Journal of Sustainable Energy Planning and Management includes papers from the 2021 conference on Sustainable Development of Energy, Water and Environmental Systems (SDEWES) held October 10-15, 2021, in Dubrovnik, Croatia as well as the 7th International Conference on Smart Energy Systems held September 21-22 in Copenhagen, Denmark and two normal papers. A focus area of this issue is district heating and district cooling systems, with articles addressing resources for district heating and cooling systems, impacts of having individual district heating metres for consumers and approaches to analysing district heating systems. Another focus area is stakeholder involvement where two groups of researchers focus on stakeholders from an energy island perspective as well as from a positive energy district perspective. Both groups note the importance of factoring in stakeholders when devising transition plans. Plans for increasing the penetration of renewable energy sources for the Estonian, Latvia and Lithuanian systems are analysed using the Backbone model, finding modest increases in system costs. Lastly, an article sets up an indicator system for assessing environmental performance of European Union member states ranking, e.g., Estonian, Latvia and Lithuanian as moderate (Estonia and Latvia) to weak (Lithuania) in terms of sustainable energy performance score, based on 2019 data.

Fundamentals and Scientific Challenges in Structural Design of Cathode Materials for Zinc‐Ion Hybrid Supercapacitors

“…Manifestly, the device based on MXene/BCF electrodes with a higher mass fraction of added BCF nanospacer had a steadily increasing areal capacitance than the device based on pure MXene electrode. The device based on the MXene/BCF electrode with a mass proportion of 57.1% BCF obtained an aerial capacitance of 178.6 mF cm 2 , approximately three times the value (61.4 mF cm 2 ) based on a pure MXene electrode without BCF nanospacer (Figure 12q). Ti 3 C 2 is one of the most-explored MXene materials due to its ease of production and good electrical conductivity.…”

“…x y x y y x (2) where M can be Li, Na, K, or H, the redox reaction involves transitions between different oxidation states. It is worth mentioning that RuO 2 and MnO 2 are known to be pseudocapacitive metal oxides.…”

“…[1] Switching from fossil fuel to renewable energy technology provides the opportunity to conserve money and improve energy to the grid or even produce renewable energy onsite rather than transporting fossil fuels. [2] Nonetheless, renewable energy sources such as solar, [3] wind, [4] and tidal [5] energies are intermittent and require energy storage systems to guarantee a secure, consistent, effective, and inexpensive energy supply. Thus, developing electrochemical energy storage systems (EESS) is essential in addressing the challenges and ensuring a stable energy supply.…”

“…The issue follows up on previous special issues in the Smart Energy Systems conference series [1][2][3][4][5][6], special issues from the ICEE conference series [7][8][9] and special issues from the SDEWES conference series [10][11][12]. All three conference series have developed into being main venues for the discussion of sustainable development and for the presentation of research advances into the field.…”

Paving the way for the Paris Agreement: Contributions of SDEWES science

“…The increasing depletion of natural resources, combined with the associated environmental and global climate damage, has highlighted in the 21 st century the need for a more efficient use of energy and use of renewable energy sources. There is a an urgent issue that efficiency must increase across all links of the energy chain, from generation to final consumption, to improve economic and environmental sustainability [1,2] and that renewable technologies with potential zero carbon footprints must replace based on non-renewable fossil fuels [3].…”
