Abstract Due to short cost-effective heat transportation distance, the existing geothermal heating technologies cannot be used to develop the deep hydrothermal type geothermal fields situated far away from urban area. To solve the problem, a new multi-energy source coupling a low-temperature sustainable central heating system with a multifunctional relay energy station is put forward. As for the proposed central heating system, a compression heat pump integrated with a heat exchanger in the heating substation and a gas-fired water/lithium bromide single-effect absorption heat pump in the multifunctional relay energy station are used to lower return temperature of the primary network step by step. The proposed central heating system is analyzed by using thermodynamics and economics, and matching relationships between design temperature of return water and main line length of the primary network are discussed. The studied results indicate that, as for the proposed central heating system, the cost-effective main line length of the primary network can approach 33.8 km, and the optimal design return temperature of the primary network is 23 ℃. Besides, annual coefficient of performance and annual exergy efficiency of the proposed central heating system are about 3.01 and 42.7%, respectively.

Abstract Nowadays, oil is not only a necessary energy for industrial development but also an important strategic resource for the international economy. Previously, many factors led to a sharp rise in international crude oil prices. Therefore, it is of great significance to explore the influence mechanism between oil price fluctuation and the macroeconomy. In this paper, the VAR model is used to quantitatively analyze the dynamic relationship between oil price, China’s GDP, China’s CPI and oil import volume, and the orthogonal impulse response analysis and Granger causality test are carried out.The results show that China’s crude oil import volume is the granger factor of GDP, that is, the early changes in China’s crude oil import can effectively explain the changes in China’s GDP. China’s CPI and GDP show a short-term inverse response, and the change in the data is more dependent on the data of the previous quarter. Given the above problems, this paper proposes that China should attach importance to the long-term stability of oil exploitation, reserves, and oil market, and maintain the stability of the oil trade market by adjusting macroeconomic and gasoline prices when necessary.

Abstract The challenge of rural electrification has become more challenging today than ever before. Grid-connected and off-grid microgrid systems are playing a very important role in this problem. Examining each component’s ideal size, facility system reactions, and other microgrid analyses, this paper proposes the design and implementation of an off-grid hybrid microgrid in Chittagong and Faridpur with various load dispatch strategies. The hybrid microgrids with a load of 23.31 kW and the following five dispatch algorithms have been optimized: (i) load following, (ii) HOMER predictive, (iii) combined dispatch, (iv) generator order, and (v) cycle charging dispatch approach. The proposed microgrids have been optimized to reduce the net present cost, CO 2 emission, and levelized cost of energy. All five dispatch strategies for the two microgrids have been analyzed in HOMER Pro. Power system reactions and feasibility analyses of microgrids have been performed using ETAP simulation software. For both the considered locations, the results propound that load following is the outperforming approach having the lowest energy cost of $0.1728/kWh, operational cost of $2944.13, present cost of $127,528.10, and CO 2 emission of 2746 kg/year for the Chittagong microgrid and lowest energy cost of $0.2030/kWh, operating cost of $3530.34, present cost of 149,287.30, and CO 2 emission of 3256 kg/year for Faridpur microgrid with a steady reaction of the power system.

Abstract Heat conduction theory stipulates that two thermo-physical properties of materials: the thermal conductivity “ k ” and the thermal diffusivity “ ” influence the temperature evolution in regular and irregular bodies as a response to various cooling/heating conditions. The traditional statement involving the two thermo-physical properties is examined at length in the present study for the case of a semi-infinite region. The primary objective of the present study is to investigate the influence of the less known thermo-physical property called the thermal effusivity “ e ” on the incipient surface temperature raise in a semi-infinite body affected by uniform surface heat flux. The secondary objective of the study is to identify a key figure-of-merit named the dimensionless threshold time that separates the incipient temperature elevation in a semi-infinite region from the incipient temperature elevation in a large wall of finite thickness under the same uniform surface heat flux . The outcome of the methodical analysis suggests that the accurate estimate for the dimensionless threshold time  in the semi-infinite region should be 0.10.

Abstract A salinity gradient solar pond (SGSP) is a large and deep artificial basin of layered brine, which collects and stores-simultaneously-solar energy for use in various applications. Experimental and theoretical studies have been launched to understand the thermal behavior of SGSPs, under different operating conditions. This article then traces the history of SGSPs, from their natural discovery to their current artificial applications and the progress of studies and research, according to their chronological sequence, in terms of determining their physical and dynamic aspects, their operation, management and maintenance. It has extensively covered the theoretical and experimental studies, as well as the direct and laboratory applications of this technology, especially the most famous and influential in this field, classified according to the aspect covered by the study, with a comparison between the different results obtained. In addition, it highlighted the latest methods to improve the performance of an SGSP and facilitate its operation, such as the use of a magnetic field and the adoption of remote data acquisition, in the aim of expanding research and enhancing the benefit of this technology.

Abstract Global warming is a thermodynamics problem. When excess heat is added to the climate system, the land warms more quickly than the oceans due to the land’s reduced heat capacity. The oceans have a greater heat capacity because of its higher specific heat and the heat mixing in the upper layer of the ocean. Thermodynamic Geoengineering (TG) is a global cooling method which deployed at scale would generate 1.6 times the world’s current supply of primary energy and remove carbon dioxide (CO 2 ) from the atmosphere. The cooling would mirror the ostensible 2008–2013 global warming hiatus. At scale 31,000 1-gigawatt (GW) ocean thermal energy conversion (OTEC) plants are estimated to be able to: a) displace about 0.8 watts per square meter (W/m 2 ) of average global surface heat from the surface of the ocean to deep water that could be recycled in 226-year cycles, b) produce 31 terawatts (TW) (relative to 2019 global use of 19.2 TW and c) absorb about 4.3 Gt CO 2 per year from the atmosphere by cooling the surface. The estimated cost of these plants is $2.1 trillion per year or 30 years to ramp up to 31,000 plants which are replaced as needed thereafter. Compared for example to the cost of world oil consumption that in 2019 was $2.3 trillion for 11.6 TW. The cost of the energy generated is estimated at $0.008/KWh.
