Abstract
In this paper we explore the tradeoffs between thermal storage capacity, cost, and other system parameters in order to examine possible evolutionary pathways for thermal concentrating solar power (CSP) technologies A representation of CSP performance that is suitable for incorporation into economic modeling tools is developed We also combined existing data in order to estimate the global solar resource characteristics needed for analysis of CSP technologies We find that, as the fraction of electricity supplied by CSP technologies grows, the application of thermal CSP technologies might progress from current hybrid plants, to plants with a modest amount of thermal storage, and potentially even to plants with sufficient thermal storage to provide base load generation capacity. The regional and global potential of thermal CSP technologies was then examined using the GCAM long-term integrated assessment model. (C) 2010 Elsevier Ltd All rights reserved

Publication Technical and Economic Potential of Concentrating Solar Thermal Power Generation in India(Elsevier, 2017-10)This study aims to assess the technical and economic potential of concentrating solar power (CSP) generation in India. The potential of CSP systems is estimated on the basis of a detailed solar radiation and land resource assessment in 591 districts across the country. The land suitability, favorable solar resource conditions and wind power density over the vicinity have been considered key parameters for potential estimation. On the basis of a district-wise solar and land resource assessment, the technical potential of CSP systems is estimated over 1500 GW at an annual direct normal irradiance (DNI) over 1800 kWh/m2 and wind power density (WPD) ≥150 W/m2 after taking into accounts the viability of different CSP technologies and land suitability criteria. The economic potential of CSP is estimated at 571 GW at an annual DNI over 2000 kWh/m2 and WPD≥150 W/m2 in India. The technical evaluation of CSP technologies over the potential locations have been carried through System Advisor Model (SAM) Software using the Typical Meteorological Year data of Meteonorm 7.0 weather database. In near future, it is anticipated that locations with DNI values ≥1600–1800 kWh/m2 could also become economically feasible with the development of new technologies, advancement of materials, efficient and cost-effective thermal energy storage, economy of scale, manufacturing capability along with the enhanced policy measures, etc. In the long-term, it is possible to exploit over 2700 GW solar power through CSP in India with an annual DNI ≥1600 kWh/m2 and WPD≥150 W/m2. The findings of this study can be used for identification of niche areas for CSP projects in India.Publication Clean Technology Fund Investment Plan Approved for Concentrated Solar Power in the MENA Region(World Bank, Washington, DC, 2009-12)The Middle East and North Africa (MENA) clean technology fund investment plan proposes co-financing of $750 million and mobilizes an additional $4.85 billion from other sources to accelerate deployment of Concentrated Solar Power (CSP) by investing in the CSP expansion programs of Algeria, Egypt, Jordan, Morocco and Tunisia. Specifically, the Investment Plan will support MENA countries to achieve their development goals of energy security, industrial growth and diversification, and regional integration. The international energy agency has identified concentrating solar power (CSP) as one of the key technologies that 'are at the heart of the energy technology revolution because they can make the largest contributions to reducing greenhouse gas emissions.' However, CSP (like most new technologies) has higher costs and risks than current technologies. Therefore, international collaboration is required to accelerate the global deployment of technologies like CSP through targeted schemes providing positive incentives for their adoption at scale.Publication Development of Local Supply Chain : The Missing Link for Concentrated Solar Power Projects in India(Washington, DC, 2013-02-01)Amid the success of Solar Photovoltaic (PV) projects in India, Concentrated Solar Power (CSP) technology also provides a compelling case for support by the government as among solar technologies; CSP is the only techno-economically viable option at present that provides a storage option for dispatchable and dependable solar energy. Furthermore, the conversion of solar to steam is a relatively high-efficiency process versus the conversion efficiency of PV. This process can effectively supplement fossil fuels and renewable fuel, such as biomass, and thus contribute to the overall energy security of the country. The specific objective of the study is to assess the potential of India's industries to set up a manufacturing base to produce CSP technology components and equipment. The study assesses competitive positioning and the potential of Indian companies in the manufacturing of important CSP components. Various analysis models were prepared for the analysis, and the details have been explained in the elaborated version of the report. The report also proposes an action plan to help develop this potential and evaluate the resulting economic benefits. This report includes the following activities: i) assessment of the competitive position of local industries to support the development of CSP technologies in India; ii) evaluation of short, medium, and long-term economic benefits of creation of a local manufacturing base; and iii) action plan to stimulate local manufacturing of CSP technology components and equipment. This document is a summary of the larger report. The data analysis and messages presented in the report are based on very limited information presently available in the Indian market. Therefore, it is recommended that the trends and ideas to be given more attention than the data itself.Publication Direct Normal Irradiance (DNI) Simulation through Empirical Approach for Concentrating Solar Power (CSP) Projects(Taylor and Francis, 2025-01-08)DNI assessment is essential for developing any CSP projects. In this manuscript, an approach is made for the analysis and estimation of DNI by developing the empirical models for India. The historical data of around 15 years (1986-2000) of DNI and cloud cover (CC) from six representative locations of major climatic zones namely Bhopal, Jaipur, Srinagar, Patna, New Delhi & Thiruvanantpuram have been employed. From these locations, first four have been used to develop the models correlating DNI and cloud cover; however, rest two were used to evaluate their validity. The standard statistical predictor’s viz. CoD, MPE, MBE, RMSE, skewness, kurtosis & chi-square were applied to evaluate these empirical models. The CoD was observed greater than 0.8 while performance criteria have low and acceptable values (MPE-11.4% to -13.77%; MBE 0.49 to 0.96; RMSE 1.22 to 1.44; Skewness 0.90 to -0.15; Kurtosis 0.90 to -1.36 and Chi-square 6.87 to 8.50). The adequecy of empirical models was evaluated through comparing estimated and measured DNI for New Delhi and Thiruvanantpuram which coincides very closely. The study established an approach to estimate DNI using cloud cover data which may facilities CSP projects developers for site selection and decision making in the absence of ground data.Publication Concentrating Solar Power in Developing Countries : Regulatory and Financial Incentives for Scaling Up(Washington, DC: World Bank, 2012-06-28)Concentrating Solar Thermal power (CST) has a tremendous potential for scaling up renewable energy at the utility level, diversifying the generation portfolio mix, powering development, and mitigating climate change. At present, different CST technologies have reached varying degrees of commercial availability. This emerging nature of CST means that there are market and technical impediments to accelerating its acceptance, including cost competitiveness, an understanding of technology capability and limitations, intermittency, and benefits of electricity storage. Many developed and some developing countries are currently working to address these barriers in order to scale up CST-based power generation. This report: a) analyzes and draws lessons from the efforts of some developed countries and adapts them to the characteristics of developing economies; b) assesses the cost reduction potential and economic and financial affordability of various technologies in emerging markets; c) evaluates the potential for cost reduction and associated economic benefits derived from local manufacturing; and d) suggests ways to tailor bidding models and practices, bid selection criteria, and structures for power purchase agreements (PPAs) for CST projects in developing market conditions. The report also presents a review of typical cost structures for parabolic trough and power tower plants, which was derived from projects developed or under preparation in Spain and the United States specifically for this report, and an in-depth assessment of the respective cost drivers.
