  • Molten salt for parabolic trough applications: system simulation and scale effects

    The trend of solar thermal power plant engineering towards lower investment and energy costs leads to a demand for higher operating temperatures in the plant cycle. The use of molten salts withstanding temperatures up to 550 °C is considered for use in CSP plants, in particular for parabolic trough systems. In thermal storage systems fluids as “Solar Salt” (NaNO3/KNO3) are already ...

  • CSP technology advances crucial for cutting costs in South Africa

    With some of the highest levels of Direct Normal Irradiance (DNI) in the world, CSP is positioned to play an immense role in South Africa’s energy landscape. Currently, four CSP technologies are being promoted internationally, parabolic trough, power tower, fresnel and dish stirling, but with the lack of operational data in South Africa the industry is still evaluating the suitability of ...

  • Determining performance characteristics crucial for CSP

    Why is the performance testing of newly developed plants important for the future of large scale projects in the US? As the development of large-scale CSP projects begins in the United States, the ability to accurately determine the performance characteristics in the efficiency, heat losses and overall power output of plants under operation is essential for generating widespread confidence in CSP ...

  • Morocco`s first CSP plant forges path to tech-led cost cuts

    The imminent start-up of Morocco's Noor I CSP Plant will be followed by lower cost adjacent plants thanks to technology gains such as larger trough apertures which have eclipsed the impact of higher cost dry cooling systems, Driss Berraho, Business Development Manager at ACWA Power, told CSP Today. A consortium led by ACWA Power started construction on the ...

  • Energy performance India vs. Spain: As the DNI values are similar, how is the energy yield?

    Technical Top Tip courtesy of Suntrace Solar Resource Assessment 1. Comparison between India and Spain When it comes to solar irradiation in India, everyone would expect this to be better when compared to Spain, for example. With respect to the Global Horizontal Irradiation GHI, which is relevant for Photovoltaic (PV) projects, this is truly the case. In ...

  • What Are Solar Buildings Technologies?

    Solar buildings technologies use the non-polluting power of the sun to help heat, cool, and power our buildings. Because buildings now use one-third of the energy currently consumed in this country, the potential markets for using solar buildings technologies in place of conventional ones is substantial. Whether you're a home owner, architect, builder, business owner, or industry or utility ...

  • Rotork valve automation at solar power plants - Case Study

    Overview Spain is now the world's largest generator of electricity from solar power plants. Spanish solar energy plants utilise parabolic trough technology combined with a thermal storage system using molten salt batteries to maximise their power generating capacity. The parabolic trough is constructed as a long parabolic mirror with a Dewar tube running its length at the focal point. ...

  • The progress of the SunShot Initiative examined at CSP Today USA 2013

    CSP Today USA 2013 (26-27 June, Las vegas) will host exclusive SunShot Initiative roundtables to share the latest R&D aimed at driving down CSP costs and optimizing system efficiency. Since the U.S. Department of Energy launched its Sunshot Initiative in February 2011 the program has funded over 150 projects focused on the research and development of Photovoltaic (PV) and ...

  • The rise of Fresnel technology is heavily aided by the consolidation in the CSP industry

    The need for increasing project scale is driving a round of partnerships and acquisitions that could soon see the CSP industry reduced to a few vertically-integrated monoliths and this could be aiding the raise of the Fresnel technology with AREVA entering strongly this market. In an industry that has seen more than its fair share of mergers and acquisitions in the last couple of years, ...

  • Opening markets for CSP – the industrial heat application

    Heavy industry can be a viable secondary market today for CSP producers, but questions remain on whether start-up costs are justifiable for industrial users, and how reliable CSP can be for processes that can't pace production by the sun. Solar thermal heat implies steam, and industries that need steam include refining, food processing, wood-working, desalination and chemicals, among others. ...

  • Wind power growth in the US

    Last year was a banner year for renewable energy in the United States, especially for the wind industry. As the recent REN21 Renewables 2007 Global Status Report highlights, the industry broke all past global records, installing 5,244 megawatts (MW) of new wind energy capacity in 2007, or 30 percent of all new U.S. capacity added. This brings the cumulative national total close to 17,000 ...

  • India’s PV-led solar growth casts eyes on performance of CSP projects

    India's CSP industry is seeking maximized output from Reliance Power’s 125 MW Fresnel-based plant and progress in four parabolic trough projects to provide competitive cost references in a market pressured by PV growth, industry sources said. It has now been a year since the 125 MW Reliance Areva plant, Asia’s largest Concentrated Solar Power plant, went into operation at Dhursar, ...
