An almost spring-like spirit of optimism currently prevails in the world of renewable energy. The various developments around the DESERTEC concept make us all hopeful, as the ideas’ implementation is truly gaining momentum.
No sooner the groundbreaking collaboration with DESERTEC Power in Saudi Arabia was accomplished than the newest reports from there give account of a technical milestone: The PFFC technology (Point Focus Fresnel Collector) is another technology in the spectrum of solar energy generation bringing many advantages. PFFC actually works quite simple: rows of flat mirrors are used that follow the path of the sun. Thus the insolation is being focused on the same area at any time of the day, guaranteeing maximum efficiency. We are talking about a “mini-tower power plant”, if you will, which might be of interest for small and decentralized applications just as well.
Somewhere else on the globe new insights are being gained on the subject of the “Global Grid", a world-spanning power supply network. Researchers at the ETH Zurich found that the transmission costs in a global network of suppliers of solar, wind and water energy will not be higher than for electricity generated from conventional power plants. This invalidates a key argument of the critics of suchlike approaches and concepts. And yet another prejudice gets tackled: energy from renewable sources does not necessarily have to be more expensive! Australia just announced that supply from renewable sources is already on a par with conventional energy production there.
We would like to conclude with a success message from Germany: Our partners at Dii welcome First Solar, an exciting new addition to the group of shareholders. First Solar has been fighting with great conviction for the DESERTEC idea and will continue to be a driving force on the journey from vision to reality.
The bottom line is clear: Spring is coming slowly, but sustainably.
