South Korea is advancing its ambitious space-based solar power (SBSP) project, with the Ministry of Science and ICT securing a budget to develop critical technologies for launching solar power satellites by 2035. This pioneering project aims to establish a 120 GW solar network in space by 2050, a move set to significantly boost the country’s renewable energy supply and position it as a leader in next-generation power generation.
SBSP Project Goals and Timeline for South Korea space solar
South Korea’s space-based solar power project, spearheaded by the Ministry of Science and ICT, is poised to revolutionize renewable energy. The initiative, involving two national research institutes, has secured initial funding to develop the core technologies required for a system capable of delivering around 1 terawatt-hour (TWh) of electricity to the grid annually. The goal is to launch a 500 kW verification satellite by 2035, with the ultimate aim of creating a massive 120 GW solar network in space by 2050.
This initiative is a significant step beyond the country’s current terrestrial energy goals, which you can learn more about in the South Korea Solar Panel Manufacturing Report.
To achieve this long-term vision, the project follows a carefully planned roadmap. The Ministry plans to demonstrate the 500 kW solar power satellite by 2035, while the Korea Aerospace Research Institute (KARI) will first build a smaller 3 kW experimental satellite by 2028. This two-step approach is designed to test, validate, and refine the technology, laying the essential groundwork for a full-scale SBSP system within the next two decades.

Technical Challenges and Solutions for South Korea space solar
SBSP is a groundbreaking concept that involves deploying vast solar arrays in geostationary orbit to collect uninterrupted solar energy, which is then transmitted wirelessly back to Earth. This approach offers game-changing advantages over terrestrial solar power, as it can generate electricity 24/7, unaffected by weather, cloud cover, or the day-night cycle.
However, turning this science-fiction concept into reality requires overcoming immense technical hurdles. A key challenge lies in the design and deployment of the solar panels themselves. The proposed system may use thousands of panels made from rollable, thin-sheet materials to minimize weight and complexity, which is crucial given the high cost of launching mass into orbit. Understanding the basics of solar panel manufacturing provides a foundation for appreciating the advanced manufacturing process needed for these space-grade systems.
Perhaps the most significant challenge is perfecting wireless power transmission (WPT). This technology involves converting the collected solar energy into focused microwaves or laser beams and beaming them to a receiving station (rectenna) on Earth. This process demands exceptionally efficient and precise transmission systems to ensure energy is delivered safely and with minimal loss. The Ministry of Science and ICT has already made promising progress, conducting successful experiments using drones and small aircraft to test microwave transmission, providing valuable data to refine the technology.
Economic and Environmental Impact of South Korea space solar
The space-based solar power project is forecast to have a profound economic and environmental impact on South Korea. By 2050, the 120 GW solar network could supply a substantial portion of the nation’s energy, drastically reducing its reliance on imported fossil fuels and helping it achieve ambitious carbon reduction targets.
Beyond clean energy, the project is a powerful engine for economic growth. The development and deployment of SBSP technology will create high-skilled jobs and catalyze new industries. This includes sourcing specialized raw materials for space applications and developing sophisticated manufacturing machines for satellites and components. The financial scale of such an undertaking is immense, far exceeding even a large-scale terrestrial solar panel manufacturing plant cost breakdown.
The South Korean government sees this project as a cornerstone of its strategy to become a global leader in both renewable energy and space technology. By investing heavily in SBSP, South Korea is positioning itself at the forefront of the emerging green energy economy, attracting significant international investment in its clean energy and technology sectors.
Other nations, including the United States, Japan, and China, are also exploring space-based solar power. As satellite launch costs continue to fall, these once-futuristic projects are becoming increasingly viable. South Korea’s comprehensive approach and firm commitment, however, place it in a strong position to lead this global race.
By 2050, the dream of harnessing the sun’s power from space could be a reality, thanks to the vision of South Korean scientists and engineers. If successful, this project will not only transform the nation’s energy landscape but also serve as a powerful model for a sustainable global future.
