Space-based solar panels could supply 80% of Europe’s renewable energy by 2050, according to a ground-breaking study from King’s College London. Researchers incorporated NASA’s heliostat-based SBSP system, which utilizes mirror-like reflectors to absorb sunlight in orbit and send it to Earth for conversion into electricity, using a comprehensive computer model of Europe’s power infrastructure across 33 countries. According to research published in Joule, Space-based solar panels could supply 80% of Europe’s renewable energy to help Europe achieve its net-zero goals while reducing its dependency on land-based renewables, lowering power system costs by 15%, and reducing battery usage by more than two-thirds.

Revolutionizing Europe’s Energy Grid

The study’s computer model, which models the demand, production, and storage of power throughout Europe, finds SBSP to be an affordable way to meet the continent’s energy requirements. SBSP provides continuous gigawatt-scale power above the atmosphere, in contrast to weather-dependent and irregular terrestrial renewable sources. The NASA-inspired heliostat system gathers sunlight using circling reflectors and directs it to ground stations where it is transformed into electrical power.

When incorporated into the model, SBSP significantly reduced the requirement for expensive battery storage devices by replacing 80% of Europe’s land-based renewable energy. According to the researchers, SBSP may reduce the total cost of the European power system by 15%, which would make it a desirable substitute for conventional renewable energy sources. However, the model could not fully account for issues like beaming variability, orbital congestion, and transmission disruptions, highlighting possible concerns that need more research.

Challenges and Opportunities for Implementation

Space-based solar panels could supply 80% of Europe’s renewable energy, and it has a lot of potential; however, there are obstacles to its widespread use. Until technical developments lower costs, which are probably not going to happen until 2050, space-based infrastructure is not economically practical due to the enormous costs of developing, launching, and sustaining it. The study’s lead author, Dr. Wei He, emphasized hazards that might compromise SBSP dependability, such as possible impacts with space debris or harm to solar panels in orbit.

Despite these obstacles, Europe is well-positioned to create centralized SBSP infrastructure thanks to its history of international collaboration, which is demonstrated by cross-border electricity exchanges and satellite projects run by the European Space Agency. A continent-scale solution that reduces dependency on gas-fired power and provides steady, baseload renewable energy might be made possible by such collaboration. Dr. He highlights that SBSP’s steady energy supply may be essential in displacing fossil fuels and supporting international initiatives to reach net-zero emissions.

The analysis concludes by highlighting SBSP’s potential to transform the renewable energy scene in Europe by 2050 completely. Europe might use space-based solar power to provide a dependable, affordable, and sustainable energy supply by utilizing international cooperation and developing technological capabilities. “Now is the time,” as Dr. He says, to investigate this cutting-edge technology, which has the potential to drastically lessen the continent’s reliance on fossil fuels and open the door to a cleaner, greener future.
