Introduction

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.

Inside SBSP Technology

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.

Orbital solar arrays
Large-area photovoltaic or concentrating solar panel arrays deployed in geostationary orbit — capturing uninterrupted, weather-free solar radiation at 8× the average ground-level intensity.
Microwave power transmission (MPT)
Conversion of DC solar power to microwave radiation and directed beam transmission toward Earth. Operating at ~2.45 GHz, MPT beams are safe — peak intensity ~230W/m², roughly a quarter of noon sunlight.
Laser power transmission
Alternative to microwave WPT using high-power laser beams — enabling smaller receiving apertures and potentially higher efficiency in clear-sky conditions, at the cost of atmospheric interference sensitivity.
Rectenna ground receivers
Rectifying antenna arrays converting received microwave power directly back to DC electricity — large-area, lightweight receiver fields that can overlay compatible land uses such as agriculture or parking.
Satellite attitude & beam control
Precision pointing systems maintaining continuous beam alignment between geostationary satellites and ground receivers across a 36,000 km distance — critical for transmission efficiency and safety.
Modular satellite assembly
In-orbit construction and assembly of large-scale SBSP satellite structures from modular components — enabled by robotics, autonomous construction systems, and reusable launch vehicle cost reduction.
Thermal management in orbit
Passive and active thermal control systems managing the extreme temperature cycling experienced by orbital solar hardware — essential for long-lifetime reliability in the space environment.
24/7 baseload power delivery
Unlike terrestrial renewables, SBSP delivers consistent power regardless of weather, season, or time of day — potentially eliminating the need for grid-scale battery storage to back up intermittent renewable generation.
GBSP vs SBSP comparison

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
Challenges addressed

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.

01
Intermittency & the grid storage problem
Solar and wind generate power only when conditions allow — requiring massive, costly grid-scale battery storage or backup fossil generation to maintain supply reliability. SBSP's continuous power delivery from orbit eliminates the intermittency problem entirely, potentially making large-scale grid-level storage unnecessary
Baseload
02
Massive land requirements for renewables
A solar farm equivalent to national grid demand would require enormous land areas in prime sunlight zones — creating land use conflicts, ecosystem impacts, and geographic concentration of generation assets. SBSP generates power in orbit and delivers it anywhere on Earth's surface, freeing up land for other uses
Land
03
Geographic concentration of solar resource
High-quality solar resources are concentrated in equatorial and desert regions, often far from population centers requiring power. SBSP transmits power directly to any location on Earth's surface, decoupling generation geography from consumption geography and reducing long-distance transmission infrastructure requirements
Geography
04
Carbon baseload power gap
Industrial processes, heating, and data centers require reliable 24/7 power that current renewables cannot consistently provide without fossil fuel backup or nuclear. SBSP offers a genuinely carbon-free baseload power source — the only renewable technology capable of delivering consistent, dispatchable power without energy storage
Carbon
05
Remote & disaster power access
Grid extension to remote areas, military forward operating bases, or disaster zones is expensive and logistically challenging. SBSP's ability to beam power to portable receivers anywhere on Earth could provide resilient, grid-independent power to underserved regions, remote operations, and emergency response scenarios
