Special Issue Information

Dear Colleagues,

In recent decades, energy consumption has been increasing at fast rate, which has resulted in an increase in greenhouse gas emissions. Hence, there is a need for the implementation of renewable energy systems that are clean and sustainable. Sustainability is considered an important factor in the improvement of people’s health and comfort in urban areas. The continuous growth in terms of the building of large cities with dense populations has resulted in negative impacts on the environment due to the use of fossil fuels to power such large cities. Smart technologies could help in reducing these negative effects, such as through the implementation of renewable energy systems for providing electricity, heating, cooling, and freshwater production to reduce greenhouse gas emissions.

Moreover, the transportation sector plays a large role in generating negative impacts on urban environments. Hence, sustainable transport alternatives aimed at reducing the number of cars in urban areas should be investigated.

This Special Issue will focus on sustainable energy solutions for urban areas, with the aim of delivering social and environmental benefits, as well as the efficient use of renewable energy systems.

These systems can be evaluated from different perspectives. This Special Issue will cover a wide range of sustainable energy systems, with the optimization of urban areas from thermodynamic, economic, and environmental points of view, including the following:

  • Energy, exergy, economic, and environmental analysis;
  • Enviromental impact assessment of the system;
  • Economic assessment of the system;
  • Life cycle assessment of the system;
  • Risk assessment and reliability engineering;
  • Sustainability-based analysis;
  • Social and policy aspects of environmental management;
  • Supply chain management;
  • Smart cities and resilient environments;
  • ICT, smart grid, and intelligent infrastructure;
  • Big data, machine learning, and artificial intelligence applications;
  • System optimizaton methods;
  • Zero CO2 emission policies and schemes;
  • Renewable energy conversion and electric machines.

By the year 2020, 90% of the population with access to electricity worldwide was surpassed. However, the reality is very different for many countries, especially for those on the African continent that had more than 572 million people without electricity service at the end of 2019. This work studies the implementation of an isolated microgrid activated with photovoltaic energy and energy storage in batteries under the case study of the community of Bigene, located in the African country of Guinea-Bissau. This type of project is a potential solution to the problem of access to energy, but as the cost of the energy storage system is typically very high, this work technically and economically addresses the effect of using absorbed glass material (AGM) and lithium batteries. A simulator was developed using TRNSYS software to analyze the operation of the microgrid under a defined annual demand profile for different types of users, and economic analysis was conducted considering a project lifetime of 25 years. The results showed no significant differences in the solar fraction of both types of batteries when the photovoltaic power was less than 600 kW, regardless of the capacity of the storage bank. The analysis of auxiliary power requirements showed that lithium technology leads to a lower consumption from 800 kW of PV capacity, and utilizing less than this capacity did not have a significant difference with AGM batteries. In this microgrid with a photovoltaic capacity of less than 700 kW and an energy storage of less than 2580 kWh, the type of storage technology, AGM or lithium, did not represent a considerable difference in the levelized cost of energy, indicating that AGM technology could be selected considering its low initial investment cost compared to lithium batteries.

To meet electricity requirements and provide a long-term, sustainable existence, remote areas need to promote renewable projects. Most of the time, wind and solar power sources are selected as renewable energy technologies to help satisfy some of the power requirements. Alternative approaches should be employed, considering the inconsistent characteristics among those resources, to offer efficient and long-lasting responses. Electricity production needs to be conducted with the help of a wide range of energy sources to be productive and efficient. As a result, the current research concentrates on feasible analyses of interconnected hybrid energy systems for such remote residential electricity supply. To help a remote area’s establishment decide whether to adopt renewable electricity technology, this paper evaluates the techno-economic effectiveness of grid-connected and standalone integrated hybrid energy systems. The electricity requirements for the entire selected remote area were determined first. Furthermore, the National Aeronautics and Space Administration, a national renewable energy laboratory, was used to evaluate the possibilities of green energy supplies. A thorough survey was performed to determine which parts were needed to simulate the interconnected hybrid energy systems. Employing the HOMER program, we conducted a simulation, optimizations, and economic research. Considering the net present cost, cost of energy, and compensation time, an economic comparison was made between the evaluated integrated hybrid systems. The assessment reveals that perhaps the grid-connected hybrid energy system is the best option for reliably satisfying remote areas’ energy needs. Full article
