TerraSpark Raises €5 Million to Advance Space-Based Solar Power Technology
Luxembourg-based startup TerraSpark has raised over €5 million in a pre-seed funding round to advance its space-based solar power (SBSP) technology. The funding will support further development of the technology, alongside preparations for pilot applications and live demonstrations.
The round saw participation from Daphni, Sake Bosch, better ventures, Hans(wo)men Group, Luxembourg Business Angel Network, and Karaoke Club.
Aiming to Build Space-Based Energy Infrastructure
Founded in 2025 by Jasper Deprez, Sanjay Vijendran (CTO), and Matthias Laug (COO), TerraSpark is developing a modular approach to capture solar energy in space and transmit it wirelessly to Earth.
“Space-based solar power has long been considered something for the distant future. Across Europe, energy resilience is now a practical concern, not an abstract one. With our step-by-step approach and starting with commercially viable systems on Earth, we are convinced that space-based solar power can become real infrastructure within a realistic timeframe,” said Jasper Deprez, founder and CEO of TerraSpark.
The founding team brings experience across space technology, entrepreneurship, and platform scaling, with prior work spanning ESA programmes, global startups, and technology ventures.
Wireless Power Transmission Model
TerraSpark’s technology focuses on capturing solar energy in orbit and transmitting it to Earth using radio frequency beams. A ground-based rectenna converts these radio waves into usable electricity, enabling continuous and weather-independent energy supply.
While the concept has existed since the 1970s, the company noted that declining launch costs and advancements in satellite manufacturing and orbital robotics have improved its commercial viability.
As an initial step, TerraSpark is focusing on Earth-based wireless energy transmission for industrial use cases, aimed at validating safety, efficiency, and regulatory compliance before scaling to orbital deployment.
Phased Roadmap for Deployment
The company has outlined a three-phase roadmap for deployment. In 2026, it plans to demonstrate wireless power transmission over controlled distances on Earth. Between 2027 and 2028, it aims to test power beaming from orbit using a satellite prototype.
“In the coming months, TerraSpark will prepare its first pilot applications and demonstration use cases – including wireless power supply for a live event. An orbital technology demonstrator is also planned for 2027. At the same time, the company is laying the groundwork for its first space-to-Earth power transmission, planned for 2028,” mentioned the company in the press release.
By 2030, TerraSpark targets full-scale commercial deployment, including a constellation of space-based solar satellites designed to deliver continuous and reliable energy worldwide.
