Terraspark, a Luxembourg-based startup developing space-based solar energy using a modular approach, has completed its pre-Seed funding round, raising over €5 million to further advance the technology and prepare for initial pilot applications and live tests.
The round was supported by Daphni, Sake Bosch, the investor alliance better ventures, the Hans(wo)men Group, the Luxembourg Business Angel Network, and Karaoke Club.
“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.
Founded in 2025 by Deprez, Dr Sanjay Vijendran (CTO), and Matthias Laug (COO), Terraspark is developing (SBSP) with a long-term goal of beaming solar energy from orbit, establishing a system that is continuously operational, weather-proof, and accessible worldwide.
Deprez is a serial entrepreneur who built Tradler into a global HRTech platform. Dr Vijendran was responsible for the Solaris programme on space-based solar energy at the European Space Agency (ESA) and was involved in the Mars Sample Return Mission. Laug is co-founder of Lieferando and Tier Mobility and brings experience in building and scaling large European platform companies.
According to the company, Europe’s energy infrastructure is nearing capacity, which became apparent during the 2025 power outage in Spain and Portugal. Fragile grids, increasing demand, and overloaded transmission infrastructure across Europe highlight the difficulty in ensuring reliable energy. Rising electricity demand, driven by expanding data centres for AI, further strains the system.
The company states that the International Energy Agency (IEA) expects the energy demand of data centres to more than double by 2030. In off-grid regions and applications that currently depend on diesel generators, electricity costs often range from €0.70 to €1.50 per kilowatt hour. Even where clean energy is plentiful, it often cannot be transported efficiently to consumers. Any long-term solution must address both clean energy generation and global transmission.
Terraspark believes that space-based solar energy provides a solution. In orbit, solar energy is steady, unaffected by weather, and accessible worldwide.
The concept has been known since the 1970s, but today, falling launch costs and advances in satellite manufacturing and orbital robotics make its implementation economically viable. The company captures solar energy in space and safely transmits it to Earth via radio frequency.
Instead of beginning with large orbital systems, TerraSpark is launching on Earth, focusing on the commercialisation of radio frequency-based wireless energy transmission for industrial uses. It notes that this approach demonstrates safety, efficiency, and regulatory compliance, and prepares initial pilot applications before scaling the system into orbit.
Explaining its modus operandi, Terraspark mentioned that it captures solar power in orbit. That energy is transmitted to Earth as radio waves using a steerable beam. A rectenna on the ground converts the radio waves into usable electricity. Batteries are only needed to plug some brief, predictable gaps.
“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.
The company’s mission roadmap comprises three phases. In Phase 1 (2026), it aims to wirelessly transmit power over controlled distances on Earth, validating alignment accuracy, energy density, and atmospheric tolerance. Phase 2 (2027-2028) includes demonstration of power beaming from orbit, where it will deploy an SBSP satellite prototype to beam solar energy from orbit to a ground receiver, demonstrating high-precision, efficient transmission from space to Earth. Phase 3 (2030) focuses on commercial deployment, with full-scale space-based solar power satellites entering orbit. From this point, it will begin constructing a constellation capable of delivering continuous and reliable energy worldwide.
