USA: Californian Solar Process Heat Potential and Gas Price Competitiveness

Submitted by Baerbel Epp on November 19, 2016
Researchers at the US National Renewable Energy Laboratory (NREL) have observed a renewed interest in solar process heat applications in recent years, mainly thanks to “the improvement and proliferation of solar collectors for electricity generation and the development of sophisticated solar collector modelling tools.” Last year, two of those researchers – Parthiv Kurup and Craig Turchi – conducted a study on the potential of solar process heat provided by concentrating collector technologies in California (see the attached document). This study, entitled Initial Investigation into the Potential of CSP Industrial Process Heat for the Southwest United States, was supported by the US Department of Energy and was published in November 2015. The chart taken from it shows the annual energy use of steam in industry segments which utilise the largest amount of gas. The study’s authors found the temperature range from about 120 to 220 °C to be of great interest, as it enables the use of concentrating optics and of water as the heat transfer fluid.

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).

Global Potential of Concentrating Solar Power (2009)

Submitted by Hans Craen on November 13, 2009

This paper presented at the 2009 SolarPaces Conference in Berlin sets out an analysis of the potential of concentrating solar power (CSP) on a global scale. The paper starts with assessing the level of direct normal solar irradiation needed for CSP plants which is combined with an analysis of the suitable land resources based on various site criteria.

Solar Thermal Power Generation: Potential in Algeria & Hassi R’Mel Project (2008)

Submitted by Hans Craen on October 2, 2009

This presentation from 2008 assesses the potential of Concentrating Solar Power (CSP) development in Algeria. The first part gives a general overview of the basics of CSP after which the presentation explains how solar thermal energy is being promoted through renewable energy related programmes.

The main targets for Algeria are to increase the renewable energy production to 5% by 2010 as well as the energy export via under-sea connection to the European market.
