About Space Solar

Enabling Net-Zero and global energy security with Solar Power from Space

Space Solar has a single corporate priority. To develop Space-Based Solar Power for the benefit of our stakeholders and the world. Our work will support the transition to Net Zero and provide global energy security, delivering a safe and secure world where clean, affordable energy is available to all.

Our History

Space Solar – a company built on collaboration, fuelled by imagination.

The founders of Space Solar first established the Space Energy Initiative (SEI) to bring together the space and energy sectors and demonstrate to government the broad support for this ambitious concept. The SEI is now a collaboration which includes UK Government and over 80 organisations, with a shared belief in the potential and vision of Space-Based Solar Power. The SEI forms a world-class innovation and manufacturing powerhouse to develop and industrialise the technology.

Space Solar was established as a commercial entity for ownership and delivery of the Space-Based Solar power development programme.
