SOcool Project on SunOyster cooling to receive EU grant


Feasibility study will assess four different forms of solar cooling, both electrically and thermally driven. All of them powered by the SunOyster.


Brussels/ Hamburg, 20 June 2016. SunOyster Systems GmbH (SOS), the Hamburg-based manufacturer of the CPVT system SunOyster, is among the few German companies to pass the evaluation phase of the new SME instrument of the European Commission.

The EU instrument offers a 70 per cent funding for small and medium enterprises – in particular YICs (Young Innovative Companies) like SOS – to realize their project in the topic “Stimulating the innovation potential of SMEs for a low carbon and efficient energy system”. While during the first phase the company shall prepare a detailed feasibility study, the second phase offers up to 2.5 M€ grants to implement the business plan. The success rate of German SMEs in this program is well below 10%, for start-ups like SOS even lower.

Increasing demand for air conditioning with worldwide more than 100 million units of compression air conditioners sold alone in 2014 has led to dramatic growth in electricity demand in many countries, to increasing electricity costs and brownouts. An obvious possibility to counter this trend is to use the same energy for cooling that contributes to the cooling demand – solar energy.

The objective of the SOcool Project is to use a concentrating photovoltaic/thermal (CPVT) system – the SunOyster – combined with chillers to provide the most cost-efficient solar energy on the market in form of electricity, heat and cold. This shall help achieving the 2K target of the Paris Convention while enhancing the living standard in rather hot climates, also as an adaptation strategy to global warming.

The SunOyster is a concentrating solar technology which can generate at the same time electricity and heat with a high total energy efficiency of 75%. From serial production, this will result in very low electricity and heat costs. While the electricity can easily be converted into other forms of energy and can be fed into the grid, the heat is more difficult to convert and has to be used locally. A technically, micro-economically and macro-economically very good form of using the heat in hot climates is converting it into cold for the cooling of buildings.
The biggest markets will be Southern Europe (Spain, Southern France, Italy, Greece and Turkey), Northern and Southern Africa, the Gulf region, India, South-East Asia, parts of China, Southern USA, parts of Middle and South America.

The preparation of the project application was accompanied by Dr. Harald Eifert and his Hamburg team of EuRA Consult AG. The feasibility study shall draw on the experience of French solar cooling expert Dr. Daniel Mugnier who is also heading the IEA Solar Heating and Cooling Task 53 on innovative solar cooling systems. Several SunOyster customers have already ordered small solar cooling systems or are in the process of doing so.
