“…Batch adsorption experiments were carried out, where about 0.1 g of the membrane was immersed into 50 mL of 20 mg L -1 adsorbate solution at the temperature of 90 °C. At first, the silicate adsorption efficiency of the membrane was studied with varying parameters of pH (3)(4)(5)(6)(7)(8)(9) and contact time (10-60 min). Then, the sample from PLTP Geo Dipa Dieng was interacted with the adsorbent in the same condition.…”

Silica scaling is a common problem in geothermal power generation facilities which inhibits electricity generation. In order to provide a solution to this problem, the removal of silicate ions using CPEG-TOMAC (Chitosan-polyethylene glycol–trioctyl methyl ammonium chloride) membrane adsorbent was investigated for geothermal brine from Geo Dipa Energy, Dieng. The process is dependent on contact time, pH, and the concentration of silicate. An adsorption batch study that used adsorbents for the geothermal brine of the Dieng Geo Dipa reactor 28A showed that CPEG TOMAC at pH 6 resulted in an adsorption capacity of 72.6 mg g–1. Furthermore, the adsorption of silicate ions onto the membrane followed pseudo-second-order kinetics and the Freundlich isotherm model.

“…The polymorphs of this compound, both crystalline and amorphous, have essentially constant solubility between pH 2 and 8.5 but increases rapidly from 9 onwards [7]. However, the solubility is highly affected by temperature, i.e., 100-140 ppm at ambient temperature and 300 ppm at 70 °C [3,8].…”

This article provides a critical review of the literature on the relationship between renewable energies and sustainability considering the three dimensions of sustainability: economic, social, and environmental. First, a bibliometric tool is used and then a more in-depth analysis of selected literature is performed, focusing on the type of renewable energy analyzed and the level of development of countries, the dimension of sustainability focused on and the country’s development level, and the type of renewable energies focused on and the dimension of sustainability analyzed. It represents a milestone in the topic giving insights on the state of the art of the research on this research area, enhancing empirical evidence on the kind of relationships and developing a discussion on how closely aligned the political and institutional discourses are with the research concerns. We conclude that, while studies on lower-income countries focus on lower-rung energies, studies on higher-income countries focus on the study of more diversified sources. Moreover, wind–solar energy is the most reported in the articles concerned with environmental sustainability. Our main recommendation is to further investigate the implementation of modern renewable energies in developing countries, to help those countries to climb the energy ladder toward cleaner energy supply.

“…Possible improvements of a GTTP with flash-binary system using a double flash system, together with a thermo-economic evaluation, have been explored in [26]. Performance evaluation of GTTP in terms of pollutants emitted has also been explored in [27], where the authors analyze which is the best solution for an existing plant among a double flash, single flash-binary and double flash-binary layouts, in order to obtain the maximum output power and the lowest excess deposit of silica. Furthermore, tools for selecting optimum power generation cycles used for GTTPs based on a detailed analysis of the Hg related to Mercury thermodynamic performance are available in literature [28].…”
