“…A lot of geothermal resources belong to the low-temperature category, they are being used in combined heat and power plant (CHP). For water with a temperature below 100 • C, binary (Organic Rankine Cycle) power plants are usually installed and used to generate electricity [2,3]. An example is the former USSR binary power plant, 680 KW using 81 • C water at Paratunka on the Kamchatka peninsula [4].…”

Much attention has been paid to the application of low temperature thermal resources, especially for power generation in recent years. Most of the current commercialized thermal (including geothermal) power-generation technologies convert thermal energy to electric energy indirectly, that is, making mechanical work before producing electricity. Technology using a thermoelectric generator (TEG), however, can directly transform thermal energy into electricity through the Seebeck effect. TEG technology has many advantages such as compactness, quietness, and reliability because there are no moving parts. One of the biggest disadvantages of TEGs is the low efficiency from thermal to electric energy. For this reason, we redesigned and modified our previous 1 KW (at a temperature difference of around 120 • C) TEG system. The output power of the system was improved significantly, about 34.6% greater; the instantaneous efficiency of the TEG system could reach about 6.5%. Laboratory experiments have been conducted to measure the output power at different conditions: different connection modes between TEG modules, different mechanical structures, and different temperature differences between hot and cold sides. The TEG apparatus has been tested and the data have been presented. This kind of TEG power system can be applied in many thermal and geothermal sites with low temperature resources, including oil fields where fossil and geothermal energies are coproduced.

“…In this issue, Luo et al (2017) conducted a geothermal potential evaluation and development prioritization based on geochemistry of geothermal waters from Kangding area, eastern syntax of Himalayan geothermal belt in western Sichuan, Southwest China, a place where high-temperature resources were found only recently. Tang et al (2017) discussed the distribution and genesis of the same area in Southwest China. Wang et al (2017) presented a review of geothermal energy resources and development in the Tibet Autonomous region.…”

“…The spring temperatures in this hot water zone are controlled by the tectonic setting and aquifer lithology. In the Kangding geothermal field, the springs exposed in the crystallized limestone show lower temperature (the temperature at EDQ springs is mostly around 40 ∘ C) and show high temperature in the contact zone with granite (i.e., the spring temperature of Yulingong hot water zone can be as high as 91 ∘ C; also the temperature in ZK201 geothermal well in this area can reach 208 ∘ C at the bottom depth of 267 m [2]). In Litang geothermal field, the springs are located along Litang fault and exposed by the fractures within the contact zone of granites, limestone, and andesite-basalt.…”

“…Near the Eastern Himalayan syntaxis, the trend of mountains and rivers transitions from a near east-west direction to a southward direction toward India. As one of the important medium-high temperature geothermal belts in China, the eastern Tibetan Plateau geothermal belt (also called Kangding-Litang-Batang geothermal field) is located in the northeast of this region [2]. A number of hot springs with temperature range within 15 ∘ C∼90 ∘ C are distributed along different fault zones and attracted numerous tourists every year.…”

The eastern Tibetan Plateau geothermal belt is one of the important medium-high temperature geothermal belts in China. However, less work has been done on the hydrochemical characteristic and its geological origin. Understanding the chemical characteristics and the hydrochemical evolution processes is important in evaluating the geothermal energy potential in this area. In the present study, we discussed the hydrochemical properties and their origins of 39 hot springs located in the eastern Tibetan Plateau geothermal belt (Kangding-Litang-Batang geothermal belt). Cluster analysis and factor analysis are employed to character the hydrochemical properties of hot springs in different fault zones and the possible hydrochemical evolution processes of these hot springs. Our study shows that the hot springs can be divided into three groups based on their locations. The hot springs in the first group mainly originate from the volcanic rock and the springs in the second group originate from the metamorphic rock while the springs in the third group originate from the result of mixture of shallow water. Water-rock interaction, cation exchange, and the water environment are the three dominant factors that control the hydrochemical evolution process in the eastern Tibetan Plateau. These results are also in well agreement with the isotopic and chemical analysis.
