Solar Thermal Power Plants
THE BENEFITS OF SOLAR THERMAL POWER PLANTS Solar thermal energy production requires two main things: sunlight and equipment to capture, store and disperse the energy. Only two types of solar thermal systems exist. They are the passive systems, which do not require equipment (such as the heat build-up in your car whenever you park it in the sun), and active systems which require a method to ...

Solar thermal power coming to a boil
After emerging in 2006 from 15 years of hibernation, the solar thermal power industry experienced a surge in 2007, with 100 megawatts of new capacity coming online worldwide. During the 1990s, cheap fossil fuels, combined with a loss of state and federal incentives, put a damper on solar thermal power development. However, recent increases in energy prices, escalating concerns about global ...

A solar thermal power system in the city of Thessalonica with the use of the Pinch method for entropy minimisation
The objective of this paper is to create a small power plant, (producing 2 MW annually), which will be using solar energy as a driving fuel. The system is made up of three sub-systems: a set of Solar Collectors (SCS), a Rankine power cycle and a Heat Exchanger Network (HEN). Two cases with variations in the operation of the solar collectors and the heat exchanger network will be examined. The ...

Growing a local concentrated solar thermal power economy in South Africa
In recent months South Africa has seen a dramatic change in its energy policy as the Department of Energy, NERSA and Eskom have taken steps to move to a renewable energy future. On November 4th the Independent Power Producer bidding process for the first 200MW of CSP will close, leaving many anxious developers waiting until COP17 to find out if their project has won the tender. In answering the ...

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, ...

A technical note on performance testing of a solar box cooker provided with sensible storage material on the surface of absorbing plate
A box type solar cooker having a double glass cover and a plane mirror reflector has been tested for its thermal performance. In the present study, performance of solar box cooker has been compared by using two different sensible heat storage materials (sand and granular carbon). By using these materials as a mixture and spread it over absorber tray in the form of thin layer and fully packed with ...

Solarthermal parabolic trough power plants with integrated storage capacity
Parabolic trough power plants use concentrated direct insulation for steam generation in a Rankine cycle. The fundamentals for direct steam generation in parabolic troughs have been developed in recent years, the feasibility was successfully demonstrated at a solar powered test facility reaching steam temperatures of 400°C at a maximum pressure of 100 bar. Important components for the accelerated ...
