The Sun never stops shining in space, and sunlight is much more intense there than on Earth's surface. So what if we could gather that energy up in space then beam it down to Earth?Recent studies funded by the Preparation element of ESA’s Basic Activities programme, show the concept, called Space-Based Solar Power, is theoretically workable and could support the path to decarbonising the energy sector. However, significant uncertainties and technical challenges remain. In response ESA is proposing a R&D programme to mature the concept and its critical technologies – SOLARIS.
SOLARIS will help decide if it is feasible to add Space-Based Solar Power – a decades-old concept for delivering clean energy – to the list of alternative sources of energy.
