A space solar power satellite system or SSPS can generates electricity without CO2 gas nor harmful debris with competitive cost. So, it should be attached importance in SDG and ESG programs. The SSPS is a huge system working in space so that several key technologies have to be innovated or verified in space before the final manufacture. I will introduce those key technologies in terms of difficulty in applying to SSPS. In a research and development plan, key technologies with more difficulty should be ranked higher. Antennas are typically difficult ones. It is explained how the antenna is challenging compared with the existing antennas on the ground and in space. Finally, I will show you a R&D plan to put SSPS into practical use in about 30 years.
