What is space solar power (SSP)?

Space solar power (SSP) proposes to launch a device into space that collects solar power and beams it down to Earth at radio frequencies. It was proposed decades ago as an alternative power source to meet the need for clean, reliable, and dispatchable energy. However, earlier SSP proposals have faced significant technical or economic challenges.

What is a space satellite power supply system?

For any space satellite system to be effective, an electrical power supply system is required to supply constant power to all the components and subsystems. The main purpose of the electrical power system is to provide regulated power to space satellites loads during launch.

What is Caltech space solar power system (cssps)?

Proposed is the “Caltech Space Solar Power System (CSSPS),” a system composed of (1) a photovoltaic-to-radio frequency (PV-to-RF) power station (PS) in geostationary orbit (GEO) and (2) a terrestrial ground station connected to the grid. The PS operates at three levels of hierarchy.

Can solar power be collected in space?

The system proposed above is an end-to-end solution for clean energy by collecting solar power in space and beaming it down to Earth at RF. Collecting solar power in space offers the benefits of a 24 h collection time, continuity despite adverse weather, and flexibility to decide when and where power is sent.

Could space-based solar power be a centralized and weather-independent energy resource?

Space-based solar power (SBSP) could offer a centralized, weather-independent energy resource to help address these challenges. 6 By operating above the atmosphere and outside the day-night cycle, SBSP promises continuous gigawatt-scale power.

Could a space solar power station be the first?

As SBSP technology improves, many nations might compete to be the first in developing fully operational space solar power stations for the sake of securing energy independence and the economic advantages brought by an unlimited power source.
