A recent study by researchers at King's College London has unveiled the immense potential of space-based solar power (SBSP) to meet Europe's net-zero targets by 2050. The technology could reduce reliance on terrestrial renewable energy sources by up to 80%, significantly cutting the need for battery storage by over two-thirds. Furthermore, adopting this technology could slash the overall energy system costs for Europe by up to 15%, translating to an estimated annual saving of €35.9 billion.

This study is the first of its kind to assess the utility of generating solar energy in space for European power grids and provide a cost estimation for the European market. The findings are based on NASA designs for space-based solar power generation, slated for use by 2050. This trend presents a substantial investment opportunity, with the global SBSP market projected to grow, driven by advancements in satellite technology and decreasing launch costs.
