“…On the other hand, CSP outside China does not follow the same trajectory: the average cost of new non-Chinese stations is USD 0.17 per kWh, which is indeed lower than 3 years ago, but far from competitive with other 1 The Chinese stations are 60% towers with on average 10.2 h thermal storage, built by Chinese developers (100%) and with Chinese EPCs (90% of projects for which we have data; data is missing for 4 of 13 projects). 2 The non-Chinese stations are 80% trough stations, including 4 hybrid projects, with on average 4.7 h thermal storage, and they are built by European or US developers (60%) and EPCs (100%). technologies.…”

“…Concentrating solar power (CSP) is one of few technologies that can provide dispatchable renewable power on a large scale. As it can both generate bulk renewable power and be built to compensate fluctuating renewables like wind power and solar PV, it could play a key role in the decarbonisation of power systems worldwide [1][2][3][4][5][6]. Despite these advantages, CSP has led a life in the shadow of other renewables, and its expansion has been slow and confined to just a handful of countries.…”

After three years of low growth and an increase in global costs, the announcement and implementation of the Chinese demonstration programme for concentrating solar power (CSP) has changed the outlook for the technology from gloomy to better than ever. Here, we analyse the Chinese CSP strategy, its drivers, and its effects on CSP industry and costs in China and globally. We find that the Chinese demonstration programme has led to the emergence of new CSP industry actors, and that it helped to the reduce global average costs of new CSP stations to USD 0.12 per kWh. However, the Chinese expansion, which is supplied almost exclusively by Chinese companies, follows a wholly different cost trajectory than the expansion in the rest of the world, which is almost exclusively served by non-Chinese companies: whereas costs in both markets have decreased, the cost of Chinese CSP stations under construction is 40% lower than that of plants built elsewhere. We conclude that the Chinese support programme has thus succeeded in its central aims of leapfrogging and has built up a domestic industry capable of building stations and most components at lower costs than foreign competitors. However, Chinese companies are not yet active outside China, nor do we find many foreign participants in the Chinese market. The effects of the Chinese CSP programme on markets and industries outside China have thus far been limited: the Chinese and non-Chinese markets currently largely exist in parallel, each with their own supply chains. Whether the new Chinese companies seek to and manage to conquer the global market as well remains to be seen but so far, they have not.

Summary Increasing demand of electricity and severer concerns to environment call for green energy sources as well as efficient energy conversion systems. SCO2 power cycles integrated with concentrating solar power (CSP) are capable of enhancing the competitiveness of thermal solar electricity. This article makes a comprehensive review of supercritical CO2 power cycles integrated with CSP. A detailed comparison of four typical CSP technologies is conducted, and the cost challenge of currently CSP technologies is pointed out. The thermophysical properties of sCO2 and the corresponding two real gas effects are analyzed elaborately to express the features of sCO2 power cycles. An extensive review of sCO2 layouts relevant for CSP including 12 single layouts and 1 combined layout is implemented logically. Strengths and weaknesses of sCO2 power cycles over traditional steam‐Rankine cycle generally adopted in current CSP plants are concluded, followed by metal material degration summary in CSP relevant temperature sCO2 environment, which shows that the nickel‐based alloy is a proper structural material candidate for sCO2‐CSP integration. Thermodynamic analyses of sCO2 power cycles when integrated with CSP are divided into three level of which design‐point analysis and off‐design modeling are conducted and compared, more researches into the off‐design point analysis, dynamic modeling, especially the transient behavior are suggested. Economic analysis of the integrated system is concluded and presents a considerable levelized cost of electricity reduction of 15.6% to 67.7% compared to that of state of art CSP. Taking the thermodynamic and economic analysis into consideration, target designs of sCO2 power cycles for CSP are summarized in three aspects. Finally, current theoretical and experimental researches of sCO2 power cycles integrated with CSP for market penetration are introduced. The strengths, weaknesses, and potential solutions to the gaps of three potential pathways (molten salt pathway, particle pathway, and gas phase pathway) to realize the integration of sCO2 power cycles in the next CSP generation plants up to 700°C are reviewed. In general, the integration of sCO2 power cycles with CSP technologies exhibits promising expectations for facilitating the competitiveness of thermal solar electricity.

“…This feature makes CSP a dispatchable electricity resource available whenever there is customer demand, including at times when the sun is not shining. CSP with TES offers considerable flexibility, increasing its own value to the grid and even enabling greater grid penetration of variable-generation technologies such as photovoltaic power plants [15,16]. Instead of examining the feasibility of implementing PT-CSP in Palestinian territories as introduced in [17][18][19][20][21], this paper inspects the effect of dispatchability of PT-CSP power plants over PV power systems.…”

This paper investigates the impacts of dispatchability of Parabolic Trough Concentrated Solar Power (PT-CSP) systems over PV power plants in Palestinian territories. Jericho governorate was taken as a case study. All conditions required for implementing PV and PT-CSP systems are verified. The capacity of each investigated system is 1 MW, and both systems are investigated in terms of technical, economic, and environmental aspects. The parametric analysis is used to identify the most feasible option of each renewable energy system by varying the cost of each option candidate and introducing thermal energy storage (TES) to the technology of PT-CSP systems with different capacities. A software based on the MATLAB environment is programmed to estimate the energy produced from each system with the important technical, financial, and environmental indicators. It is found that the alternative of installing a 1 MW PV system is the installation of 1 MWe PT-CSP systems with 14.5 h or 18.5 h TES. Introducing TES improves the dispatchability of the system and the capacity factor which consequently justifies the PT-CSP system investment. Increasing the degree of dispatchability improves the capacity factor of the PT-CSP system from 21% at 0 h TES to 57% at 18.5 h TES (24 h operation). The capacity factor of the PV system is 18.7% which is mostly similar to PT-CSP with zero dispatchability (0 h TES). The study considers the environmental benefits by estimating the amount of avoided CO 2 emissions, and it was found that increasing the capacity factor augments the environmental benefits.
