Summary

Geothermal energy is a clean, sustainable and renewable source of energy. It is one of the most attractive source of renewable energy due to its independence on weather conditions as the case for wind and solar energy sources, hence it is a continuous source of energy. Little research has been done on geothermal energy though this source of energy is abundant worldwide. Moreover, it has a wide range of applications such as electricity production, space cooling, district heating, drying, desalination, agriculture and aquaculture. This special issue will focus on the most recent technologies related to geothermal energy. Energy, exergy, economic and exergoenvironmental analysis (4E) of geothermal power and hybrid power plants will be presented. Thermodynamic analysis of geothermal heat pumps using different organic fluids will also be presented. The use of geothermal energy for cooling and heating purposes will be discussed. This special issue will cover the impacts of geothermal on environment as well as hydrochemical assessment of ground water quality.

    Thermodynamic Performance Analysis of Geothermal Power Plant Based on Organic Rankine Cycle (ORC) Using Mixture of Pure Working Fluids

    Abdul Sattar Laghari, Mohammad Waqas Chandio, Laveet Kumar, Mamdouh El Haj Assad
    Energy Engineering, Vol.121, No.8, pp. 2023-2038, 2024, DOI:10.32604/ee.2024.051082

    Abstract The selection of working fluid significantly impacts the geothermal ORC’s Efficiency. Using a mixture as a working fluid is a strategy to improve the output of geothermal ORC. In the current study, modelling and thermodynamic analysis of ORC, using geothermal as a heat source, is carried out at fixed operating conditions. The model is simulated in the Engineering Equation Solver (EES). An environment-friendly mixture of fluids, i.e., R245fa/R600a, with a suitable mole fraction, is used as the operating fluid. The mixture provided the most convenient results compared to the pure working fluid under fixed operating More >

    Applying an Ordinal Priority Approach Based Neutrosophic Fuzzy Axiomatic Design Approach to Develop Sustainable Geothermal Energy Source

    Chia-Nan Wang, Thuy-Duong Thi Pham, Nhat-Luong Nhieu
    Energy Engineering, Vol.121, No.8, pp. 2039-2064, 2024, DOI:10.32604/ee.2024.050224

    Abstract Geothermal energy is considered a renewable, environmentally friendly, especially carbon-free, sustainable energy source that can solve the problem of climate change. In general, countries with geothermal energy resources are the ones going through the ring of fire. Therefore, not every country is lucky enough to own this resource. As a country with 117 active volcanoes and within the world’s ring of fire, it is a country whose geothermal resources are estimated to be about 40% of the world’s geothermal energy potential. However, the percentage used compared to the geothermal potential is too small. Therefore, this… More >

    A Feasibility Study of Using Geothermal Energy to Enhance Natural Gas Production from Offshore Gas Hydrate Reservoirs by CO2 Swapping

    Md Nahin Mahmood, Boyun Guo
    Energy Engineering, Vol.120, No.12, pp. 2707-2720, 2023, DOI:10.32604/ee.2023.042996
    (This article belongs to the Special Issue: Advances in Geothermal Energy)
    Abstract The energy industry faces a significant challenge in extracting natural gas from offshore natural gas hydrate (NGH) reservoirs, primarily due to the low productivity of wells and the high operational costs involved. The present study offers an assessment of the feasibility of utilizing geothermal energy to augment the production of natural gas from offshore gas hydrate reservoirs through the implementation of the methane-CO2 swapping technique. The present study expands the research scope of the authors beyond their previous publication, which exclusively examined the generation of methane from marine gas hydrates. Specifically, the current investigation explores the… More >
