Special Issue Information

Dear Colleagues,

This Special Issue is a continuation from our previous Special Issue “Energy Systems and Applications in Agriculture”, which was successfully closed in June 2022. In this special issue, we wish to attract publications focused on energy-related systems, materials, and applications, which are emerging in agricultural and mechanical engineering fields. Energy has become the most crucial requirement for the development of any nation. It is directly linked to the quality of human life and thereby to the 2030 United Nations’ Sustainable Development Goals (UN-SGDs). Primary energy is either expensive or not available sufficiently at least in the developing countries. In this regard, scientists and researchers are working worldwide for the development of state-of-the-art energy-related systems and materials for agricultural and industrial applications.

Agriculture, as a production-oriented sector, entails energy as a substantial input by which global food security is ensured. Agricultural systems use energy as fuel or electricity for farm machinery and equipment; HVAC and built environment; and food preservation and transportation. Similarly, industrialization is involved in various kind of energy systems and materials. Increasing agricultural mechanization and mechanical industrialization mitigate conventional energy reserves, which also escalates greenhouse gas emissions (GHG) and climate change. Therefore, it is important to develop energy-efficient and environment-friendly energy systems and materials for agricultural and industrial applications to achieve the UN-SGDs.

This special issue is aimed to showcase recent advancements and improvements of such energy systems and their technologies for various applications accordingly. This special issue will consider cutting-edge research works and review articles focus on energy system design; advance energy materials; integration of renewable energy; automation and control; modelling and simulation; life cycle assessment of energy systems and applications; alternate/sustainable energy sources; emerging production systems; agricultural and mechanical practices/applications. In this regard, the special issue includes (but not limited) to the research theme mentioned in the following keywords:

  • Agricultural built environment
  • Biomass, biogas, and bioenergy
  • Computational methods and AI in energy systems
  • Emerging air-conditioning systems
  • Energy efficiency and management
  • Energy-efficient agriculture
  • High efficiency irrigation systems
  • Hybrid energy systems
  • Integrated energy systems and applications
  • Life cycle assessment of energy systems
  • Low-energy sowing and seedbed preparation
  • Low-energy spraying and harvesting
  • Materials and manufacturing in energy systems
  • Next-generation greenhouses
  • Post-harvest/food processing/storage
  • Robotics and farm mechanization
  • Solar dryers and solar water pumping
  • Sustainable energy and clean fuel
  • Temperature and humidity control systems
  • Thermal management and efficiency
  • Water/wastewater treatment and energy

Over the past decade, the integration of desiccant technology with evaporative cooling methods has proven to be highly effective and efficient in providing comfortable indoor environments. The performance of desiccant-based direct evaporative cooling (DEC) systems is strongly influenced by environmental conditions, and their output behavior varies across multiple climatic zones. It is not easy to assess the system performance in numerous climatic zones as it is a time-consuming process. The current study focuses on determining the feasibility of a solid desiccant integrated with a direct evaporative cooler (SDI-DEC) for three different climatic zones of Pakistan: Lahore (hot and humid), Islamabad (hot and semi-humid) and Karachi (moderate and humid). To serve this purpose, a specially designed controlled climate chamber with an integrated air handling unit (AHU) was installed to create multiple environmental conditions artificially. It could also provide global climatic conditions under temperature and absolute humidity ranges of 10 °C to 50 °C and 10 g/kg to 20 g/kg, respectively. The weather conditions of the selected cities were artificially generated in the climate chamber. Based on different operating conditions, such as inlet air temperature, humidity and regeneration temperature, the performance of the system was estimated using performance indicators like COP, dehumidification effectiveness, solar fraction and supply air conditions. Results showed that the maximum temperature achieved from solar collectors was about 70 °C from collectors with an area of 9.5 m2. Moreover, the observations showed that when the regeneration temperature was increased from 60 °C to 80 °C, the COP of the system decreased about 41% in a moderate and humid climate, 28% in a hot and semi-humid environment and 23% in a hot and humid climate. The results revealed that an SDI-DEC system has the potential to overcome the humidity and cooling loads of the multiple climatic scenarios of Pakistan. Full article

The reuse of lignocellulosic biomaterials as a source of clean energy has been explored in recent years due to the large amount of waste that involves human activities, such as those related to agriculture and food. The anaerobic digestion (AD) of plant-based biomass for bioenergy production poses a series of challenges that new technologies are attempting to solve. An improved decomposition of recalcitrant lignocellulose together with an increase in biogas production yield are the main objectives of these new approaches, which also seek the added value of being environmentally friendly. Recent research has reported significant progress in this regard, offering promising outcomes on the degradation of lignocellulose and its subsequent transformation into biomethane by specialized anaerobic microorganisms, overcoming the drawbacks inherent to the process and improving the yield of methane production. The future of the agri–food industry seems to be heading towards the implementation of a circular economy through the introduction of strategies based on the optimized use of lignocellulosic residues as a source of clean and sustainable energy.
