IEA SHC: Global Technical Solar Process Heat Potential

Submitted by Baerbel Epp on December 29, 2016
Solar Process Heat PotentialThe 191 solar process heat projects which have made it into the online database add up to an installed capacity of 0.11 GWth (0.159 million m²), which is only a small fraction of the potential estimated for this type of application. To quantify the technology’s global opportunities, the researchers from the now-completed four-year Task 49 / IV, Solar Heat Integration in Industrial Processes, analysed the results of several national studies which had tried to determine the potential of solar process heat while considering restrictions such as temperature range and the space available for the systems (see the chart on the left). “For Europe, where mainly non-concentrating collectors had been investigated, the percentage of technical potential for solar process heat related to the total industrial heat demand is around 3 to 4 %,” was the conclusion by the authors of the attached report Potential studies on solar process heat worldwide.

IEA SHC Task 46: Solar Irradiation Data Helps Schedule and Operate Solar Thermal Plants

Submitted by Baerbel Epp on April 19, 2015
Irradiation ChartIEA SHC Task 46, Solar Resource Assessment and Forecasting, is an SHC project conducted in cooperation with IEA’s SolarPACES for Concentrating Solar Power and the Photovoltaic Power Systems programme. Accurate assessment and forecasting of solar irradiation is a key issue in planning and operating solar electricity and solar thermal plants. Task 46 has been evaluating various forecasting models and standardisation procedures for irradiation measurement, for example, regarding detail and accuracy. Numerical Weather Prediction and cloud models based on satellite images (CM-sat) with their up-to hourly resolution are detailed enough for rough estimates of solar generation capacities within the next hours and days. Grid integration and power plant control, however, require algorithms based on CM-SI (Cloud Models based on Sky Imaging) time-series modelling to forecast irradiation seconds or a few hours away (see figure on the left).

International Technology Collaboration and Climate Change Mitigation - Case Study 1: CSP technologies (2004)

Submitted by Hans Craen on July 29, 2009

This case study from 2004 was prepared by the OECD and IEA secretariats and reviews past and current experiences in international collaboration in the field of CSP technologies. In addition to identifying the success stories and the failures of CSP related international collaboration, the case study also lists four important lessons:

1) International collaboration may help, but domestic policy decisions remain decisive

2) In technology transfer non-financial barriers must not be underestimated
