SolarReserve has achieved a new milestone in itsCrescent Dunes CSP plant at Nevada. The molten salt receiver has been completely assembled atop the 540 ft tower
Crescent Dunes is a 110 MW tower plant under construction near the town of Tonopah that will be the first US commercial plant to use molten salt as Heat Transfer Fluid (HTF). Thanks to a couple of storage tanks, the molten salt --potassium and sodium nitrate-- heated at the receiver can be stored to be used when there's no sunlight. The plant is designed to operate for up to 10 hours with the stored heat.
Turkish energy company Greenway has completed the construction of Turkey’s first “concentrated solar power tower plant” (CSP) in the southern province of Mersin, which is located on one of the world’s major Sun Belt areas.
The plant, which has been built with an investment of $50 million by Greenway with the support of Turkey’s science watchdog TÜBİTAK and the Technology Development Foundation of Turkey (TTGV), generates 5 MW of thermal power, equivalent to the energy requirement of 1,500 houses.
“Turkey is located on a major sun belt and is lucky compared to many countries that develop technology in this field,” Co-founder of Greenway and Project Management Director Serdar Erturan said in a statement.
Erturan noted that major world powers had been placing a special focus on solar power plants as a substantial power generation source in response to the increasing energy demand due to rising technological needs.The plant is used as one of the most efficient methods to convert solar power to electricity across the world. While it’s one of its kind in Turkey, it also marks many firsts in the world.
There are similar tower type plants in Spain, Israel and the U.S., and the Greenway Mersin CSP stands out for its wireless communication system as well as its lego type design, which enables easy transfer, installation and easy access to the site.
The plant utilizes only water and solar light, and by focusing solar energy over the tower, it enables reaching high temperatures. Reflective panels consist of unique glass mirrors and system components and energy production processes contain only environment friendly materials. The only output of the system is the high pressure steam.
“Thanks to hybrid and compact systems that lower costs to competitive levels and are not dependent on external sources in technological terms, it is possible to generate energy from renewable energy sources, at high outputs and competitive prices,” Erturan said.
A nanowire manufacturing technique promises to improve solar cell efficiency at a low cost. Photovoltaic panels enhanced with nanowires can be up to 25% more efficient than traditional PV panels. While the concept was demonstrated several years ago, one obstacle remained: producing these nanowires and adding them to PV panels at a reasonable cost. Solar upstart Sol Voltaics, founded by nanotechnology expert Lars Samuelson, has developed a nanowire production process that promises to make nanowire PV cells cost effective. Rather than growing nanowires on a silicon substrate, a process that’s both slow and costly, Sol Voltaics uses a process called Aerotaxy™, which grows the nanowires in a solution of active materials and gases. The result is a material that Sol Voltaics calls SolInk, which can be stored and later applied to the surface of PV panels.
Sharp Corporation has achieved the world's highest solar cell conversion efficiency*1 of 37.9%*2 using a triple-junction compound solar cell in which three photo-absorption layers are stacked together.
Sharp achieved this latest breakthrough as a result of a research and development initiative promoted by Japan’s New Energy and Industrial Technology Development Organization (NEDO)*3 on the theme of "R&D on Innovative Solar Cells." Measurement of the value of 37.9%, which sets a new record for the world's highest conversion efficiency, was confirmed at the National Institute of Advanced Industrial Science and Technology (AIST).
Alors qu'ils sont déjà menacés de disparition, les lamantins de Floride succombent par dizaines suite à la prolifération d'algues nocives.
Les biologistes craignent le pire pour les lamantins avec l'arrivée d'une marée "rouge" suite à la prolifération d'algues qui se révèlent mortelles pour les lamantins et les poissons. Près de 200 lamantins ont déjà succombé dans le golfe du Mexique en 2013! Mais ces décès ne se limitent pas à la côte ouest de la Floride et commencent à se manifester également sur la côte est de l'Etat, près de Cap Canaveral.
"D'après les analyses, ces animaux étant en parfaite santé, on dirait qu'ils sont morts suite à un choc ou par noyade (un comble pour des animaux aquatiques" explique un biologiste.
US Department of Energy (DOE) has announced a new funding opportunity (FOA). The “Efficiently Leveraging Equilibrium Mechanisms for Engineering New Thermochemical Storage (CSP: ELEMENTS)“ program will award $20 million to up to 24 projects to research and develop thermochemical energy storage (TCES) systems to be applied to Concentrated Solar Power technology.
Projects awarded under this FOA will focus on development and validation of integrated TCES systems with a minimum of six hours of thermal storage to be used in utility-scale CSP plants. Furthermore, TCES system must validate a cost below $15 per kWh-thermal and will operate at temperatures above 650 ºC.
Supply of solar water heaters far outweighs current demand. Since the inception of the Eskom solar water heater rebate programme in 2008, there has been a phenomenal growth in supply of solar water heaters (SWHs) to the market.
Between 2006 and 2010, the number of SWH suppliers in the industry increased from 45 to 700. There are currently approximately 300 active suppliers within the industry. However, a recent study conducted by Frost & Sullivan indicates that the uptake of the product by consumers has not yet been as successful as expected.
If recent work done by a joint Stanford-Korean team bears fruit, we may see a new generation of flexible, easy-to-install solar panels soon. The team, led by Hanyang University researcher Dong Rip Kim of that school's Department of Mechanical Engineering, has developed a way to laminate high-efficiency thin-film solar cells onto flexible surfaces with an adhesive backing -- offering the prospect of cheap "peel-and-stick" solar cells.
