Abstract: In this paper, we show that concentrated solar power (CSP) with thermal storage is an economically attractive technology to achieve high solar penetration levels. To this end, we utilize an alternative framework of net levelized cost of electricity (net-LCOE), which captures the projected curtailment rate, to economically compare PV with batteries to
The energy analysis and exergy analysis results show that the solar power efficiency and exergy efficiency of the considered system are 41.7% of 44.7%, which are 2.6% and 2.8% higher than the single CaL energy storage CSP system, respectively, demonstrating the superiority of the proposed strategy and system for CSP application. Furthermore, the
For example, good lighting conditions before 16:00 in summer make the heat storage system in CSP accumulate a large amount of heat. However, due to the limited capacity of the heat storage system from 16:00 to 18:00, the excess heat absorbed by the light field cannot be stored in the heat storage system. This part of the heat is directly used

The results of this study using current capital cost estimates indicate that a combination of PV and conventional gas CTs provides a lower net cost compared to CSP-TES
The overall system cost for the PV+batteries/PGP storage configuration is essentially the same as the cost for the PV/CSP with TES/batteries/PGP storage configuration, with only a marginal decrease in cost when CSP+TES is added, despite CSP+TES becoming a substantial part of the system. This behavior again suggests that, based on current cost
One of the big advantages of CSP plants (over photovoltaics) is their ability to couple with thermal energy storage (TES) systems. At present, considering an average storage cost of 22 US$/kWh th for the commercial thermal energy storage system in CSP plants, the cost of TES systems for utility scale applications is still ∼30–150 times lower than that of electricity

2 For recent surveys of CSP (and PV) costs, see Bollinger and Weaver (2013), IRENA (2012), and IEA (2010).

Why the study looked at the LCOH of just the solar collection system. An LCOE (Levelized Cost of Electricity) analysis would include the capital cost of an entire CSP plant, including thermal energy storage and a power block. However, for a modular system, this would vary depending on how many modules it incorporates. So, the study first

For the period 2010 to 2022, the global weighted‑average cost of newly commissioned CSP projects fell from USD 0.38/kWh to USD 0.118/kWh – a decline of 69%. The LCOE of CSP fell rapidly between 2010 and 2020, despite
Gen3 CSP high-temperature thermal systems have the potential to lower the cost of a CSP system by approximately $0.02 per kilowatt-hour (kWh), which is 40 percent of the way toward the solar office''s 2030 cost goals of $0.05 per kWh
In the past decade, the cost of electricity produced by CSP has dropped more than 50 percent thanks to more efficient systems and the wider use of thermal energy storage, which allows solar energy to be dispatchable around the clock
As part of the SunShot Initiative, the U.S. Department of Energy (DOE) has set a goal of lowering the levelized cost of electricity (LCOE) of baseload concentrating solar power (CSP) to 5¢/kWh
As a sustainable and environmental friendly renewable energy power technology, concentrated solar power (CSP) integrates power generation and energy storage to ensure the
Capital costs for CSP fell 50 % in the last decade to $3000–11000/kW. Adding 6–15 h of thermal storage at $20–60/kW is now considered economical. A global transition to sustainable energy systems is underway, evident in the increasing proportion of renewables like solar and wind, which accounted for 12 % of global power generation in 2022.
In contrast, CSP uses physical means for energy conversion, which has minimal harm to the environment. And due to its own technical characteristics, CSP has a heat storage device and an auxiliary power generation system, which integrates power generation and energy storage.
Renewable energy plays a significant role in achieving energy savings and emission reduction. As a sustainable and environmental friendly renewable energy power technology, concentrated solar power (CSP) integrates power generation and energy storage to ensure the smooth operation of the power system.
The cost reduction potential of CSP components is closely tied to the prices of raw materials and the scale of production. For instance, the cost of steel, which is used extensively in the construction of CSP plants, has a significant impact on the overall capital costs.
Primarily due to the stochasticity of the solar resource, CSP plants without storage operate with capacity factors in the range of 22–28 %, depending on technology and location . In comparison, including different TES capacities increases these values by more than 90 % .
Lower total installed costs and higher capacity factors are driving the decline in the cost of electricity from CSP. The LCOE of CSP between 2010 and 2012 stayed relatively stable, at a global weighted average of between USD 0.346/kWh and USD 0.353/kWh.
