Can Space-Based Solar Power Eliminate the Need for Massive Grid-Scale Energy Storage?
A data-grounded look at who is filing, where, and why it matters now.
A comprehensive technology and patent intelligence analysis of space-based solar power (SBSP) — examining orbital solar arrays, wireless power transmission (microwave and laser), rectenna ground receivers, the GBSP vs SBSP debate, and the evolving IP landscape across energy, defense, and space infrastructure.

Space-Based Solar Power — Technology & Patent Intelligence Report
The world's most abundant energy source, uninterrupted by weather or night
The world is at a crossroads, facing the dual challenge of supplying the power needs of a growing global population while combating climate change. Energy demand is accelerating due to increasing electrification and the growth of big data and AI, making current energy systems increasingly unsustainable.
While terrestrial renewables like wind and solar are crucial, they are intermittent and require vast tracts of land. The concept of space-based solar power — first proposed by Peter Glaser in 1968 — offers a compelling alternative: placing large satellites with solar panels in geostationary orbit, some 36,000 kilometres above the Earth, where they can capture uninterrupted sunlight 24 hours a day, 365 days a year.
This constant stream of solar energy is converted into microwaves and beamed down to receiving stations on the ground. The beam itself is safe — at a peak intensity of around 230W/m², it is approximately a quarter of the strength of the midday sun. In space, solar intensity is significantly higher than at Earth's surface, meaning space-based panels generate far more energy per square metre than their terrestrial counterparts, while freeing up valuable land.
Unlike terrestrial solar farms that are at the mercy of weather and the day-night cycle, SBSP provides consistent, reliable baseload power — something only achievable on Earth with fossil fuels or nuclear energy. This report examines who is building SBSP technology, who owns the key patents, what the manufacturing and deployment reality looks like, and what it all means for the future IP landscape across energy, defense, and space infrastructure sectors.

Structural components & key features
SBSP systems integrate three major technology subsystems — orbital power generation, wireless power transmission, and ground-based energy reception — each representing a distinct domain of patent activity and innovation.
How space-based solar stacks up against ground-based solar
The fundamental advantages of space-based solar over ground-based systems stem from physics — not engineering — making SBSP a genuinely different class of energy technology rather than an incremental improvement.
| Factor | Ground-Based Solar (GBSP) | Space-Based Solar (SBSP) |
|---|---|---|
| Solar intensity | ~170W/m² avg (weather, atmosphere, angle) | ~1,360W/m² in GEO orbit — consistent |
| Availability | Intermittent — day only, weather dependent | 24/7 — uninterrupted in geostationary orbit |
| Grid storage need | Requires massive grid-scale battery backup | Minimal — delivers baseload power directly |
| Land use | High — large land areas per GW capacity | Minimal on Earth — receiver arrays can overlay farmland |
| Transmission losses | Long-distance grid losses up to 10–15% | WPT beam losses; receiver-to-grid conversion losses |
| Launch & deployment cost | Low — established manufacturing and installation | Very high currently; declining with reusable launch |
| Carbon baseload potential | Cannot provide baseload without storage | Yes — equivalent to zero-carbon baseload power |
Why ground-based renewables alone cannot solve the energy problem
SBSP directly targets five structural limitations that prevent ground-based renewable energy systems from fully replacing fossil fuels as a reliable baseload power source.
