Parabolic Trough or Solar Tower? A technology decision
Securing cost reductions and carving out routes to grid parity remains as ever the most pressing issue for the CSP industry. At the crux of this pursuit is understanding the associated costs of the CSP technologies themselves, whether it be Parabolic Trough, Solar Tower, Linear Fresnel or Dish Sterling. Delving even deeper, the ability to identify and successfully implement cost reduction ...

Exergy analysis of DSG parabolic trough collectors for the optimal integration with a combined cycle
A comprehensive energy and exergy analysis was conducted for various components of a direct steam generation (DSG) parabolic trough solar collector field under nominal operating conditions to assess performance of the components and to optimally integrate them with a thermal system. The solar field was modelled mathematically to compute thermal loss and consequently the thermodynamic ...

Determining performance characteristics crucial for CSP
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 technologies. After more than 10 years in hibernation, parabolic trough technology has been revived again with ...

Studies on performance characteristics of a solar parabolic trough concentrator with a variable area absorber
The design of a suitable absorber that incorporates an efficient heat transfer augmentation technique is one of the vital parameters that affect the performance of a solar parabolic trough concentrator (PTC). The variable area absorber discussed in this paper provides appreciable augmentation in heat transfer without increasing the pressure drop materially and thus helps in enhancing the ...

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 ...

More transparency needed on solar field cost and performance
Novatec Biosol will be participating actively in the 4th International Concentrated Solar Thermal Power Summit (Nov 15-17) as an exhibitor and sponsor. The rise of the Fresnel system to the hierarchy of CSP is one of the issues that will be actively discussed at this industry flagship event with a 700 strong attendance. CSP Today: What are the next steps to achieving greater cost ...

Palen – a look back in time
Over the past year we have documented the trials and tribulations of 500 MW Palen project as developers fought to achieve the necessary permitting that would allow grid synchronization by 2016. By Jenny Muirhead After a number of setbacks it looked like the developers were finally on track. However, on 26 September 2014 Palen Solar Holdings (which consists of BrightSource Energy and ...

Generating thermal energy from the Sun – Case Study
With the rising cost of electricity from fossil fuels, solar thermal energy (STE) currently leads the way as the most cost-effective solar technology. Major solar thermal power industry players are striving to make the economics of solar power a mainstream renewable energy source. Solar thermal electric energy generation concentrates the light from the sun to create heat, and that heat is used ...

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 160 MW Noor I project in Ouarzazate, ...
