Luxembourg’s TerraSpark Raises Over €5 Million to Harness Solar Energy from Space

In an era where energy resilience is crucial, Luxembourg-based startup TerraSpark is pioneering a groundbreaking approach to solar energy. With a successful pre-seed funding round, raising over €5 million, TerraSpark aims to revolutionize how we capture and transmit solar power, promising a future where energy is abundant and accessible worldwide.

Pioneering Space-Based Solar Power

TerraSpark, founded in 2025 by Jasper Deprez, Dr. Sanjay Vijendran, and Matthias Laug, is on a mission to transform solar energy by capturing it in space and transmitting it wirelessly to Earth. The startup's innovative approach involves using a modular system to harness solar energy in orbit, offering a solution that is continuous, weather-proof, and globally accessible.

Deprez, a serial entrepreneur, previously built Tradler into a leading HRTech platform. Dr. Vijendran brings expertise from his work with the European Space Agency on the Solaris programme, while Laug, co-founder of Lieferando and Tier Mobility, adds experience in scaling platform companies.

Addressing Europe’s Energy Challenges

Europe's energy infrastructure is under strain, highlighted by the 2025 power outage in Spain and Portugal. With rising electricity demand, particularly from data centers driven by AI advancements, the continent faces significant challenges. The International Energy Agency (IEA) predicts that data center energy demand will more than double by 2030. TerraSpark’s solution offers a way to meet this demand by addressing both energy generation and transmission.

The concept of space-based solar power (SBSP) has been around since the 1970s, but recent advancements in satellite manufacturing and orbital robotics, coupled with reduced launch costs, make its implementation more feasible today. TerraSpark’s technology captures solar energy in space and transmits it to Earth using radio frequency, providing a steady and reliable power source.

Strategic Approach and Roadmap

TerraSpark is strategically launching its technology on Earth, focusing first on the commercial viability of radio frequency-based wireless energy transmission. This initial phase will demonstrate the safety, efficiency, and regulatory compliance necessary for future orbital applications.

The company has outlined a three-phase roadmap. Phase 1 (2026) will focus on wireless power transmission over controlled distances on Earth, validating critical factors like alignment accuracy and energy density. Phase 2 (2027-2028) will see the deployment of an SBSP satellite prototype, showcasing power beaming from orbit to ground receivers. Phase 3 (2030) aims for full-scale commercial deployment, with a constellation of satellites delivering continuous energy globally.

Why This Matters

For startups, founders, and investors, TerraSpark’s endeavor represents a significant shift in the energy landscape. The ability to provide clean, reliable energy from space could redefine global energy markets, offering new opportunities for innovation and investment. As launch costs decrease and technology advances, the potential for SBSP to become a mainstream energy source grows, promising both environmental and economic benefits.

Conclusion

TerraSpark’s ambitious project could mark the beginning of a new era in energy production and transmission. With their recent funding success, the company is well-positioned to advance its groundbreaking technology. As they prepare for pilot applications and future orbital demonstrations, TerraSpark is poised to lead the charge in making space-based solar power a reality.
