TerraSpark secures €5M+ to develop orbital solar power
TerraSpark has raised more than €5 million in funding from French venture firm daphni, investor Sake Bosch, and additional backers to accelerate its work on space-based solar power—a concept aimed at collecting solar energy in orbit and transmitting it to Earth.
The company’s near-term plan is to start with terrestrial demonstrations of wireless energy transmission, a critical step toward proving that power can be beamed safely and efficiently over distance before attempting full-scale deployment in space. While the long-term vision involves harvesting abundant sunlight above the atmosphere—where solar generation is not interrupted by night or weather—technical, regulatory, and cost hurdles have historically limited progress in the sector.
Why wireless transmission matters
Demonstrating reliable wireless power delivery on Earth is expected to validate core components such as energy conversion, beam steering, and receiver technology. These tests can also help address public safety concerns and provide data for regulators as companies explore how to operate transmission systems within existing spectrum and energy frameworks.
Market context and next steps
Interest in next-generation energy infrastructure has grown as governments and industries seek firm, low-carbon power sources. Advocates of space-based solar power argue it could complement terrestrial renewables by providing more consistent output, though critics point to launch costs and complex engineering requirements.
TerraSpark said the new capital will support continued research and development and advance its roadmap toward larger-scale demonstrations. The company has not disclosed a timeline for an in-orbit pilot, but the initial focus on Earth-based tests signals an effort to de-risk the technology before moving to space.
