    Future Trends of Hybrid Energy Systems
    (Elsevier, 2024) Taheri, M.H.; Seiiedhoseiny, M.; Mohammadpourfard, M.; Akkurt, G.G.
    Hybrid energy systems can be defined as a combination of at least two fuel sources or energy conversion equipment that, when combined, can eliminate the constraints related to every single component. In addition to the application of multiple renewable energy sources, the improvement of energy efficiency via multi-generation plants constitutes a significant share of the recent investigations, which would include a prominent part of the future trend in hybrid energy systems. The present chapter will review the pioneer works and tries to address the future of hybrid energy systems. © 2024 Elsevier Inc.

    Experimental Study and Kinetic Modeling of High Temperature and Pressure Co2 Mineralization
    (Elsevier Sci Ltd, 2024) Berndsen, Maximilian; Erol, Selcuk; Akin, Taylan; Akin, Serhat; Nardini, Isabella; Immenhauser, Adrian; Nehler, Mathias
    The potential for in-situ CO2 sequestration was analyzed experimentally for one basaltic hyaloclastite sample from the Nesjavellir geothermal reservoir in Iceland and three metasedimentary rock samples from the K & imath;z & imath;ldere geothermal field in Turkey. Based on batch reaction experiments, this paper demonstrates the interaction between a CO2 gas-charged fluid and rock samples from these reservoirs. The experiments were conducted at 260 degrees C and 0.8 MPa, and 105 degrees C and 17 MPa for the basaltic and metasedimentary rocks, respectively. The experimental results indicate that CO2 sequestration within the glassy basaltic rocks is hampered by zeolite, chlorite, and anhydrite, which compete with carbonate minerals to uptake divalent cations at the P-T conditions applied. In contrast, the carbonation process for the metasedimentary rocks is inhibited by their mineralogical composition. Generally, these rocks are less reactive and provide an insufficient supply of divalent cations. The batch reactor experiments were numerically simulated with the PHREEQC geochemical modeling program. The simulations indicate that CO2 sequestration is feasible at the tested P-T conditions, provided that silicate and SO4 mineralization is suppressed for the basaltic rocks and that there is an effective source of divalent cations for the metasedimentary rocks.
