Statusbericht solarthermischer Kraftwerke Erfahrungen, Aussichten und Empfehlungen zur Ueberwindung der Markthemmnisse fuer die Technologie der Parabolrinnenkraftwerke

On the base of the operational experience of the SEGS plants in California with 354 MW of total installed capacity and showing 72 plant years of operation to date, a number of feasibility studies have been launched. Despite these efforts, no facilities have been implemented further on. In this report, the status of solar thermal power plant development is explored and some insight into actual and perceived barriers dealying the commercial advancement of this technology is provided. As background, the technology is described starting with a brief overview of solar technologies, and the potential market for solar thermal plants is postulated. Integral with market considerations are an understanding of world energy and electricity growth projections, and the associated impact on the environment and global warming through emissions, both of which are treated. Technology costs, economics and financing of commercial-scale plants are discussed and recent feasibility studies and results are presented. Finally, policy recommendations and financing scenarios are postulated which could ease the path for further commericalization and accelerate future implementation.

Concentrating Solar Power

Concentrating solar power is a complementary technology to PV. It uses concentrating collectors to provide high temperature heat to a conventional power cycle. Efficient and low-cost thermal energy storage technologies can be integrated into CSP systems, allowing electricity production according to the demand profile. CSP systems can also avoid 'shadow plant capacity' needed to secure generation capacity in periods without sunshine or wind, can provide grid services, and if desired even black start capabilities. It thus supports the penetration of a high share of intermittent renewable sources like wind or PV and avoids a high share of expensive electric storage technology in the grid systems. A broader commercial implementation of CSP technology has started not until 2007 mainly in Spain and the US. Today, a capacity of almost 6 GW is in operation and another 1.5 GW are under construction worldwide. Markets in particular in the Middle East and North Africa but also in South Africa, India and China just recently started to come up. This chapter summarizes the principle, the technical requirements and the different technological concepts of CSP systems. It briefly reports on the state of the art of today's solar power plants including the current cost of solar electricity. In addition, the most relevant aspects for future cost reductions are highlighted. Finally, the worldwide potential impact of this technology to 2050 is discussed. As a further option the production of solar fuel using CSP technology is discussed

Current State of Development of Electricity-Generating Technologies: A Literature Review

Electricity is perhaps the most versatile energy carrier in modern economies, and it is therefore fundamentally linked to human and economic development. Electricity growth has outpaced that of any other fuel, leading to ever-increasing shares in the overall mix. This trend is expected to continue throughout the following decades, as large—especially rural—segments of the world population in developing countries start to climb the “energy ladder” and become connected to power grids. Electricity therefore deserves particular attention with regard to its contribution to global greenhouse gas emissions, which is reflected in the ongoing development of low-carbon technologies for power generation. The focus of this updated review of electricity-generating technologies is twofold: (a) to provide more technical information than is usually found in global assessments on critical technical aspects, such as variability of wind power, and (b) to capture the most recent findings from the international literature. This report covers eight technologies. Seven of these are generating technologies: hydro-, nuclear, wind, photovoltaic, concentrating solar, geothermal and biomass power. The remaining technology is carbon capture and storage. This selection is fairly representative for technologies that are important in terms of their potential capacity to contribute to a low-carbon world economy
