Article The West Coast Geothermal Province: Insights from Geochemical and Geophysical Exploration for Green Hydrogen Development(Geological Society of India, 2025) Deshmukh, V.; Subba Rao, P.B.V.; Chandrasekharam, D.; Sathishkumar, S.; Srinivas, Y.; Chandrasekhar, V.The West Coast Geothermal Province (WCGP), located along India’s western margin, hosts 60 thermal springs with temperatures ranging from 33 to 70°C, classifying it as a low-enthalpy geothermal system. Geochemical analyses suggest that meteoric water percolates through granitic basement rocks, gaining heat from radioactive decay and geothermal gradients. Geophysical investigations have identified shallow geothermal reservoirs and fault/fracture zones that facilitate the upward movement of deep-seated hot water to the surface. Although traditionally overlooked for power generation, low-enthalpy geothermal systems are gaining attention due to technological advancements and the growing demand for sustainable energy solutions such as green hydrogen. Reservoirs with temperatures between 150 to 180°C have the potential to generate 3–5 MWe of off-grid electricity using thermoelectric generators, supporting applications like water desalination and hydrogen production. This study evaluates the potential of WCGP’s low-enthalpy geothermal resources for green hydrogen production, with a focus on both technical and economic aspects. Key technical parameters include reservoir temperature, power generation capacity, and system integration. Economic considerations encompass the Levelized Cost of Energy (LCOE), capital expenditures (CAPEX), operational expenditures (OPEX), and hydrogen production costs. By comparing geothermal hydrogen production with other energy sources, this research assesses its viability and competitiveness within the broader renewable energy landscape. © 2025 Elsevier B.V., All rights reserved.Article Citation - Scopus: 1Audio-magnetotelluric (amt) studies over rajapur hot spring in west coast maharashtra, India(indian Acad Sciences, 2024) Deshmukh, Vasu; Kumar, P. V. Vijaya; Chandrasekaram, D.; Raju, Khasi; Sathishkumar, S.; Srinivas, Y.; Rao, P. B. V. SubbaIn the west coast geothermal provinces, the Rajapur hot spring, located in the southern part of western Maharashtra, is well thought to originate from the interaction of meteoric water with the granitic basement. A 3D AMT survey was conducted to determine the geo-electrical structure of the hot spring. Dimensionality analysis carried out by phase tensor analysis reveals complex subsurface 3D structures. 2D and 3D modelling have yielded three distinct resistivity layers in the Rajapur geothermal field. These layers include a moderately resistive surface layer representing weathered Deccan traps having a thickness of about 100 m, a conductive second layer with a thickness of about 100-400 m represents Kaladgi sediments and a deeper high resistive layer (0.5-1.0 km) representing granitic gneisses basement. High conductivity anomaly within the Kaladgi sediments represents a hydrothermal reservoir that is associated with faults/fractures beneath the Deccan Traps.
