MENA/Chile: Concentrating Solar Benchmark Costs

Submitted by Baerbel Epp on August 25, 2017
SunShotA tender for 94.5 USD/MWhel in Dubai and an R&D initiative called SunShot in the United States have shown how the cost of concentrated solar power (CSP) could be lowered at a steady pace thanks to economies of scale and optimised manufacturing and operation. Though the solar power market has been the driver for most of these developments, their outcomes are likewise relevant to solar thermal, where concentrating technologies have been used to provide heating or cooling for industrial processes. Two recent webinars organised by Spanish-based consultancy ATA Insights and focused on CSP in the MENA region and Chile had developers and researchers discuss the main drivers for cost cutting and the technology outlook in the short and medium term. The chart illustrates the SunShot aim to bring down the cost of parabolic trough collectors from around 200 USD/m² to 75 USD/m².

IEA SHC Task 46: Bankable Solar Data Sets for Concentrating Technologies

Submitted by Baerbel Epp on November 2, 2016
Whether investors put their money into large-scale concentrating solar heat and power systems, solar district heating plants or photovoltaic fields, they need to be able to rely on data sets to include the uncertainty and variability of input information. Financial institutions do like to know in what way these factors can impact revenue flows in financing, so researchers of IEA SHC Task 46, Solar Resource Assessment and Forecasting, have spent several years analysing various approaches to the topic. The flow chart of the financing model shows that solar resource data is essential to a proper assessment of the average power or heat generation per year as well as the range of variability over several years. SHC Task 46 is a five-year collaborative effort (2011-2016) with support from the IEA SolarPaces Programme (Task V) and the IEA Photovoltaic Power Systems Programme (Task 14).

The Value of Concentrating Solar Power and Thermal Energy Storage (2010)

Submitted by Raquel Ponte Costa on June 20, 2015

This is a technical paper written by the National Renewable Laboratory, a division of the US Department of Energy. The report looks at the value added by thermal energy storage to concentrating solar power in the southwestern United States. The analysis by the authors shows that thermal energy storage does add value to concentrated solar power in a number of ways. First, thermal energy storage allows a larger amount of thermal energy from a concentrated solar plant’s field to be used. Second, by giving the plant more room to allow a bigger solar field.

Solar Thermal Trends, Performance-Based Incentives, and RPS (2012)

Submitted by Raquel Ponte Costa on June 20, 2015

This presentation was created by the Clean Energy States Alliance (CESA) and was presented originally as a webinar. It focuses on trends in solar thermal and the implementation of solar thermal technology as part of renewable energy statewide portfolios. In 2011, the largest growth in the use of residential solar thermal water heating took place in Hawaii. However, there was also steady growth in commercial use in states such as California.

Concentrated Solar Power – Focusing the sun’s energy for large-scale power generation (2009)

Submitted by Raquel Ponte Costa on June 15, 2015

This fact sheet was written by the Environmental and Energy Study Institute in 2009. The document starts with a brief background on solar thermal energy and then describes the different types of solar thermal systems (parabolic trough, linear fresnal reflectors, dish/engine, power tower). It covers nighttime generation and how systems use supplemental fuels or thermal storage. The “Water and Land Impacts” section discusses land requirements for single rooftop systems to large power tower systems and water usage.

Advancement of Solar Thermal Technologies (2010)

Submitted by Raquel Ponte Costa on April 6, 2015

This presentation was created by Jane H. Davidson of the Department of Mechanical Engineering at the University of Minnesota. It focuses on large scale power generation for possible industrial use of solar thermal.

According to the presentation, concentrated solar power in the Southwest United States could be the most low cost and effective form of large scale utility generation in the region. However, some technical barriers remain to the technology, including the storage issue and inefficient receivers.

Thermal Storage Analysis in CSP Plants (2009)

Submitted by Raquel Ponte Costa on October 20, 2009

This presentation, prepared by Leonardo Energy, describes and discusses ways to improve solar thermal storage technologies, notably melted salt and concrete storage. The improvement of these technologies would allow a better profit of the energy produced by power plants.

Report CSP Workshop, South Africa (2009)

Submitted by Hans Craen on October 13, 2009

This is the report of a CSP workshop, which took place in South Africa on 22 May 2009. The workshop results from the necessity to gather project developers, the government, NGOs and research centers to start a discussion on scaling up CSP.

In South Africa, the development of CSP infrastructure has been boosted by the government which policy is to encourage renewable energy projects via financial measures and incentives such as the Renewable Energy Feed-In Tariff (REFIT) or the Clean Development Mechanism.

TREE Project – CSP Seminars in South Africa (2009)

Submitted by Raquel Ponte Costa on August 25, 2009

The TREE Project (Transfer Renewable Energy & Efficiency), run by the Renewables Academy (RENAC) in Berlin aims to promote capacity building and know-how transfer in renewable energies (RE), energy efficiency (EE) and climate protection for both decision makers from politics and business, as well as technicians and engineers in emerging countries.

Worldwide Dissemination of CSP Technologies and Resulting Economical Opportunities for the German Industry (2009)

Submitted by Hans Craen on July 22, 2009

This 2009 study from the Wuppertal Institute looks into the economical opportunities of CSP development from a German perspective. The study analyses the role German companies can play in the development of CSP technologies and how the export of these technologies to the “sunbelt” regions can benefit the different levels in the value-added chain.
