SunOyster Systems to Realize Worldwide Demonstration Projects

 

The Concentrating Solar System for Combined Heat and Power Inks Sales Contracts for Pre-Series Installations in Chile, Egypt and India

 

SunOyster Systems GmbH (SOS), the Hamburg-based manufacturer of the CPVT system SunOyster, bags several contracts to install the innovative machines in different parts of the sun belt of the world. In the various locations and climates and under diverse grid conditions of the projects, SOS wants to demonstrate the maturity of the solar co-generation system for serial production.


The SunOyster reaches a total energy efficiency of up to 75%, i.e. 30% of the direct radiation is converted into electricity and 45% into heat. The SunOyster shall be the most competitive form of solar energy where besides electricity also heat and/or cold are needed. The SunOyster wants to play an important role in filling the Framework Convention on Climate Change – which was adopted yesterday in Paris – with life.


Starting in the West, the international utility ENGIE (formerly GdF Suez), through its Chilean subsidiary Laborelec Chile SpA, wants to install two machines in Chile and one in Belgium. Northern Chile has with 3,000 kWh per year and square meter the best direct normal irradiation (DNI) in the world. That corresponds to the energy content of 300 liters or two barrels of oil per m² and year. It is no wonder that many enterprises in Chile, for example mining companies, have discovered photovoltaic energy (PV) and also concentrating solar thermal power plants (CSP) as their cheapest form of power supply. The SunOyster will concentrate the Chilean sunshine more than 1,000 times in order to generate each up to 15,000 kWh of electricity and 22,500 kWh of heat. ENGIE wants to compare the yield in Northern Chile and in Santiago de Chile with a site in Belgium in order to assess the future use of the SunOyster especially in contracting models. ENGIE is expert operator in the three businesses of electricity (largest IPP of the world), natural gas and energy services. Sebastian Falkenberg, general manager of Laborelec Chile, is still selecting different possible platforms for an installation in second quarter of 2016.


This project offers three advantages: We can prove our SunOyster in the hardest solar radiation of the world. ENGIE is a leading global energy player and of course a very potent customer. And finally the booming Chilean solar market can become interesting for us” says SunOyster Systems’ general manager Carsten Corino.


The Egyptian government is planning to reduce the present subsidies for fossil-generated electricity and to increase the share of renewable energies in the generation. DNI is frequently as high as 2,500 kWh – roughly three times the value of Hamburg. This is in particular the case for the off-grid area in which Egyptian entrepreneur Hassan Abdel Salam and his company Smart Power Solutions want to install three SunOysters in connection with an Eco Lodge. While the electricity shall replace most of the fuel used by the noisy diesel generator, the heat shall be used for thermal water desalination in order to “green the desert”. He is planning to develop the regional distribution of SunOysters.
Hassan Abdel Salam: “The African continent is facing a high increase in energy demand – in Egypt 8 % every year – and therefore a serious energy gap. Solar energy has become a very attractive option. The reason we chose the SunOyster is basically for its high efficiency of up to 75% which leads to low cost of energy. We believe we have the right product for the African market.”


In sunny India, the national government under Prime Minister Narendra Modi announced a very ambitious target of 100,000 MW solar power capacity before the end of 2022. SOS will realize several installations with renowned companies which are interested to become a future large scale customer or perhaps even a local manufacturer of the SunOyster. Tata Power, belonging to the legendary Tata group, is the largest private utility in India. Tata wants to install the SunOyster on an office building in order to heat process water for the kitchen. Solar cooking and dish washing is popular in the large Indian canteens. Another paying customer is Swelect (formerly Numeric Power) from Chennai in Southern India. The mid-sized electronics manufacturer, PV installer and solar IPP wants to use the SunOyster heat in foundries belonging to the group. Altogether, SOS estimates the process heat demand of India in the SunOyster temperature range of up to 170°C to be around 140,000 MW today. For the SunOyster, this would correspond to an additional 93,000 MW of electricity generation. Or to altogether almost 20 million SunOysters of 16 m² mirror surface each.


Additional SunOyster supply contracts in these and more countries are under negotiation.

SunOyster Systems Secures Grant of German Federal Environmental Foundation

 

High Temperature Receivers with Concentrator Cells to be Qualified

The German Federal Environmental Foundation (Deutsche Bundesstiftung Umwelt, DBU), following the development of SunOyster Systems’ (SOS) innovative receiver, is also promoting its qualification phase. The grant amounts to up to 50% of the project cost. The project runs until 30 April 2016 when SOS wants to enter the serial production of the SunOyster.


The SunOyster uses bi-axially tracking parabolic mirrors to concentrate the sunlight in one line. In that line the hybrid receiver converts the sunlight both into electricity and heat. While the first receiver model was designed with high quality back-contact silicon cells for the electricity generation, the new receiver uses a secondary concentration in form of a lens to focus the radiation of the equivalent of approx. 1,000 suns on high quality multi-junction CPV cells. These cells of a German manufacturer have presently an efficiency of 44%. With various losses, an electric system efficiency of 30% in relation to the direct radiation shall be achieved. The concentrator cells are actively cooled by water or solar fluid so that in addition 45% of the radiation becomes useful heat of up to 170°C. The receiver is protected by the international patent application PCT/EP2014/052359.


The second phase of the project has the task to test and qualify all components and the complete receiver both in the laboratory and in the field. The testing shall include several highly qualified external partners for the cells and cell assemblies, the optical system, glass tube, anti-reflex coating and compensator and tests according to the CPV standard IEC 62108 and the solar thermal standard ISO 9806.


SunOyster general manager Dr. Carsten Corino says: “We are happy that the DBU accompanies also our second phase for developing our disruptive solar technology. Several expert opinions collected by DBU have confirmed the highly innovative nature of our technology.”


The DBU is one of Europe's largest foundations and promotes innovative and exemplary environmental projects. Since 1991, ca. 9000 projects have received financial backing totaling roundabout € 1.58 billion. The promotional activities concentrate on environmental technology and research, nature conservation, environmental communication and cultural assets.
