About us
We are an experienced engineering company from Germany and have developed a suite of innovative solar thermal technologies for industrial scale applications worldwide.

Our story


The idea of Protarget was born during a business trip to California where two senior automotive and aerospace executives asked themselves why there is so much innovative and smart technology, and the world is still just talking about switching to green energy? It is obvious that the world’s dependency on fossil fuels is creating more environmental, financial and political problems than ever before. Why do we then accept that the biggest single energy consumers are industries who use process heat and produce almost anything that we as humans consume, and our deserts are not utilised to produce sustainable alternatives?


The two departmental heads from Toyota Formula One had a vision of using their extensive knowledge and experience from the high-end automotive industry to commercialise the existing renewable energy technologies. The engineers were convinced that the innovation, speed, intensity, and precision of Formula One processes can be successfully applied in a much wider segment – the industrial production of almost anything.

John Mitchell and Martin Scheuerer combined their production know-how with a scientist, Dr. Ing. Eckhard Lüpfert, from the German Aerospace Centre DLR with 30+ years scientific knowledge on solar thermal energy. The three forged the idea of taking already developed but complex and expensive Concentrated Solar Technology (CST) and scaling it down for decentralised applications. This resulted in co-founding Protarget and its first product – an innovative parabolic trough collector that provides cost-effective steam and hot water for industrial applications.


Protarget represents science and engineering excellence. Our vision is to make a notable contribution in driving the world’s industrial manufacturers towards cleaner energy alternatives. Protarget is built on fundamental beliefs such as energy security and independency, stable energy costs and reduction of CO2 emissions. The world is at the brink of change where the actions towards greener energy use and production need to take over the mere words. To put it simply, when fossil fuels run out or are cut off, and your energy gets taken away, we at Protarget will be there to fill the gap and help you to start switching.
