Exergetic assessment of transmission–concentrated solar energy systems via optical fibres for building applications
Optical fibres solar energy transmission and concentration provide a flexible way of handling concentrated solar energy. Solar lighting with Fibre Optic Bundles (FOBs) can be considered a promising option for energy–efficient green buildings. This study deals with the exergetic analysis and performance assessment of a system based on the idea of Transmission–Concentrated Solar Energy via Optical ...

Exergy of solar radiation
Solar radiation reaching the ground is accompanied with radiation entropy. When the entropy production rate within any solar energy conversion device is to be calculated, the incoming radiation entropy flux has to be known. In this contribution, first it is shown how the radiation entropy flux arriving on earth is to be calculated. Secondly, the interaction between the incoming radiation and the ...

A new type of solar concentrator employing a cone-cylinder combination
Most conventional solar thermal radiation concentrators have some sort of symmetry which allows them to concentrate solar thermal energy for their operation. We report a new system that utilises the symmetry of a cone and a cylinder combination to simulate the concentration of solar radiation on a ring containing a fluid (water). A halogen lamp is used as the source of radiation to simulate solar ...

Two scenarios for a solar world economy
Solar energy using Concentrating Solar Power (CSP) technology will become the most abundant source of renewable energy. The technology and the economics of CSP are explained. An overview is given for the deployed CSP capacity, the CSP capacity which is currently being built, and the planned capacity. We make the following assumptions: (1) The learning curve for CSP technology will finally lead to ...

Design and theoretical performance analysis of linear Fresnel reflector solar concentrator with a tubular absorber
A linear Fresnel reflector solar concentrator (LFRSC) system is used nowadays for operation at intermediate temperature ranges by using solar energy. Considerable attention is being paid to the design, fabrication and testing of solar concentrators. The performance of the system depends on the design parameters, mass flow rate, desired temperature difference, tracking accuracy, etc. In 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 ...

Siemens Takes A Good Step Towards Energy Efficiency
The contemporary world today is facing a lot of economic and environmental challenges. It is important to find a quick and sustainable solution. Siemens, the market leader in power technology, concentrates on renewable energy, solar energy and wind power especially. The demand of solar energy and wind power in the United States is increasing as it is helping the nation to achieve the state of ...

Solar power plants mw or kw?
Solar power has come as a blessing to the humanity, not only to provide energy to all but to save humanity from the evils of industrial revolution. The biggest evil of industrial revolution in last two centuries is the concentration and centralization of wealth and resources and also huge political powers in the handful of people. So huge factories, mass production, big industrial and financial ...

Alternative scenarios of the utilisation of renewable energy sources in small prefectures: a case study in Lasithi Prefecture, Greece
The sector of Renewable Energy Sources (RESs) is growing very fast, with many innovations and applications becoming a reality. The continuous reduction of natural resources has forced all policymakers to turn to alternative energy sources. The total energy (oil and electricity consumption) consumed in the prefecture of Lasithi during the years 1997?2002 in correlation with the RES exploitation ...

Flat absorbers with trapezoidal cavity for Fresnel reflecting solar concentrator
The absorber is a very important component of the solar concentrating collector. The overall heat loss coefficient of the flat rectangular absorber and multi-tube absorber were studied experimentally. Both absorbers were coated with ordinary dull black paint. The heat loss coefficient was comparatively 4-11% lower in the case of round pipe absorber and increased with the absorber temperature in ...

The alternative to coal in South Africa
With a desperate need for dispatchable generation, South Africa should be readily embracing CSP as a low-carbon, sustainable, base load energy alternative. So why do its energy authorities remain unconvinced? This question has formed the subject of Part 2 of the CSP Today South Africa Guide. London, UK October 11 2011 Forget green energy: while most nations are concerned about carbon ...

Energizing our green future
As world leaders come together at the UN General Assembly to adopt new sustainable development goals, climate change activists gear up for Climate Week in New York City and the Pope brings his message to the United Nations, a shared vision of our future is coming into clear focus. If we are to eradicate poverty, we need to tackle climate change. And since 2008, the $8.1 billion Climate ...

The thermal energy storage is the key for decarbonization
Summary Thermal energy storage plays a key role in the energy transition process. It makes possible to overcome the intermittence’s obstacle inherent to traditional renewable power generation sources (such as wind or solar), or the mismatch between available energy production and consumer’s demand, solved nowadays by inefficient management of resources, with paid plants on standby ...

Designing renewable contracts that value CSP storage
As California ramps up its storage requirements, it has not included Concentrated Solar Power (CSP) with integrated energy storage. Instead it is testing pilot projects using batteries at utility-scale, even though it must be obvious to bean counters at utilities that batteries are never going to compete with utility scale CSP storage. By Susan Kraemer The 32 MWh battery storage pilot for ...
