UK Explores Space-Based Solar Power Viability for Clean Energy by 2040
The UK is assessing the feasibility of Space-Based Solar Power (SBSP) as a clean energy option. A new report suggests that SBSP could be competitive by 2040, with initial deployment needing £7.5-16.3 billion in funding. SBSP technology could offer continuous energy supply from satellites in geostationary orbit. However, challenges remain, including high launch costs and the need for wireless power transmission technology development. The report indicates that without public funding, the economic viability of SBSP may falter despite promising long-term benefits.

The UK is exploring Space-Based Solar Power (SBSP) as a potential clean energy source, with a report from the Department for Energy Security and Net-Zero indicating it could be competitive by 2040. SBSP involves solar farms in space beaming energy to ground-based systems.
The technology requires an estimated £7.5-16.3 billion investment over 18 years, with a significant portion needing public funding. A major challenge includes the high launch costs, with reliance on future availability of Starship-class vehicles.
The report projects levelised costs of electricity could decline from £335-595/MWh in 2030 to £87-129/MWh by 2040 if key technologies are developed successfully. SBSP offers a high capacity factor, potentially providing reliable power when other renewable sources are unavailable.
