Foreign owned solar technology makes storage breakthrough

Novatec Solar – a company many owned by Australia's Transfield Liaison – has commissioned a solar heating energy demonstration plant in Spain it's based on a new type of molten sodium storage technology.

The Germany-based Novatec Solar says the new plant the particular process called direct molten sodium or DMS technology – where exactly inorganic salts are used as a burning heat transfer fluid rather than oils.

With this the plant can operate at temps well above 500°C, resulting in a vast increase in power yield. This means that value ranges are lowered significantly and the abolengo plants can act as baseload generator if required.

Andreas Wittke, CHIEF EXECUTIVE OFFICER of Novatec Solar, which is 80 per cent owned by Australia's Transfield Holdings, says this means that the solution will be able to operate on a "commercial" good reason.

"The successful commissioning and the foremost results of the DMS demo basic plant have confirmed our expectations for the technology, " he said in a very statement.

"We are delighted that i can now offer solar thermal power plantation with molten salt technology yet thermal storage on a commercial good reason. "

The use of DMS technology is that it is used at the 110MW Crescent Altitude power tower unit nearing achievement in Nevada, which will be the largest solar heating plant with storage in the world.

Novatec Solar will use DMS with its thready Fresnel technology, which has been deployed just like a demonstration "solar booster" at the Liddell coal generator in NSW (pictured), and is being mooted for a renewables-based replacement for the Collinsville coal dismissed from your job power station in Queensland.

Wittke says that the demonstration plant having southern Spain that features this new solution will be used to simulate a large number of alternative operating conditions to help develop the newly released of solar thermal power plants.

Any storage capability means that the raise the temperature of energy can either be straight converted into electrical power or be saved in large molten salt tanks ın the course of periods of low demand.

This type of stored energy can be kept having reserve for times when production is considered low, for example when the sky is considered overcast. Solar thermal power plants by using storage systems can supply electric power as and when required, which helps to assurance grid stability.

The molten sodium technology was developed by BASF on your Fresnel collector technology, which utilises flat glass reflectors rather than parabolic trough collectors.

The reflectors aim direct sunlight onto a receiver, by which the molten salt is piped. This has the effect of heating it to temperatures in excess of 500°C.

"Our knowledge of salt chemistry and the new-technology concepts are contributing to a significant production in the efficiency of solar thermal control plants, " says Kerstin Dünnwald, Head of Business Management to work with Inorganic Chemicals at BASF.

Any DMS demonstration collector project is considered supported by the German Federal Ministry for Economic Affairs and Unhealthy calories (BMWi) following a decision by the Germany parliament.
