Space-based solar power (SBSP) is emerging as a promising solution to Europe's energy challenges. A recent study by scientists from King's College London analyzed the potential of SBSP using designs based on NASA's cost and performance projections for 2050. The study found that a near-baseload, low technology readiness level (TRL) design incorporating mirror-like reflectors, or heliostats, could cut total system costs by 7% to 15%, offset up to 80% of wind and solar energy, and reduce battery usage by over 70%. This design offers nearly 99.7% annual power availability, making it a reliable and efficient energy source. pv-magazine.com
The integration of SBSP into Europe's energy mix could significantly enhance the continent's efforts to achieve net-zero emissions. By providing a consistent and abundant source of renewable energy, SBSP can complement existing terrestrial renewable sources and reduce reliance on fossil fuels. However, challenges remain, including the need for technological advancements, cost reductions, and the development of efficient wireless power transmission methods. Ongoing research and collaboration between space agencies, universities, and industry stakeholders are crucial to overcoming these hurdles and realizing the full potential of SBSP. nasa.gov
