Space Solar
Develops space-based solar power technology to beam continuous clean energy from geostationary orbit to Earth via wireless power transmission
Space Solar develops space-based solar power (SBSP) technology designed to capture solar energy in geostationary orbit and transmit it wirelessly to ground-based receivers on Earth. The company's flagship satellite design, CASSIOPeiA (Constant Aperture Solid State Integrated Orbital Phased Array), uses reflectors and a helical phased array to collect sunlight and beam power via high-frequency radio waves through 360 degrees without mechanical joints. In 2024, Space Solar demonstrated the world's first 360-degree wireless power transmission with its HARRIER prototype at Queen's University Belfast. The company completed the CASSiDi study, an 18-month UK Space Agency-funded project advancing the CASSIOPeiA design toward commercial deployment targeted from 2030. Space Solar also partners with National Grid Electricity Distribution on wireless power transmission for terrestrial grid infrastructure. Founded in 2022 and headquartered at Harwell Oxford in Oxfordshire, the company has been selected for the NATO DIANA 2026 Challenge Programme and received backing from the UK Space Agency and the Department for Energy Security and Net Zero.
