TerraSpark, a European startup developing space-based solar energy systems, raised over €5 million in pre-seed funding to advance technology and prepare pilot applications. Investors include Daphni, Sake Bosch, better ventures, the Hans(wo)men Group and strategic business angels. The company aims to deliver continuous clean energy independent of weather or time of day.
Space-Based Energy Approach
Europe faces increasing energy demand, fragile grid infrastructure and rising costs, particularly with the growth of AI-driven data centres. TerraSpark is developing orbit-based solar power combined with radio-frequency wireless energy transmission. Initial commercial applications will focus on Earth-based industrial use cases to validate safety, efficiency and regulatory compatibility before scaling to orbital systems.
"The physics behind radio frequency-based energy transfer has been validated for decades. Programs such as Solaris have laid the groundwork in Europe. The challenge today lies in the engineering discipline: building systems that scale safely and reliably. That is precisely where our focus lies," says Sanjay Vijendran, founder and Chief Technology Officer of TerraSpark and former program manager for space-based solar energy research at ESA.
Roadmap and Deployment
Funding will support pilot demonstrations, including wireless power delivery use cases, followed by an orbital technology demonstrator planned for 2027 and initial space-to-Earth transmission targeted for 2028.
