Position under active recruitment:Research and development of space solar power technology

Creating next-generation energy from outer space

Space solar power system is a technology for converting solar energy transmitted to the ground from space into electrical power. With a view to creating a sustainable society, we aim to use clean and inexhaustible solar energy from outside the Earth as a technology whose time has come.

What are the key points of space solar power technology?

Overwhelmingly clean and inexhaustible next-generation energy

■Development of a space solar power system that performs solar power generation on geostationary satellites orbiting at an altitude of 36,000 km, transmits that energy to the ground by laser, and efficiently converts that laser energy to electrical power.

■Research and development with a view to diverse applications in addition to energy transmission from space including use as a power distribution system in microgrids to supply power to mobile equipment such as drones and automobiles and to remote islands, evacuation centers during disasters, etc.

Established in July 2020, the NTT Space Environment and Energy Research Laboratory conducts research across a broad spectrum of environment and energy fields, including space-related technologies.
This group targets a society with zero environmental impact through innovative groundbreaking technologies such as nuclear fusion and space solar power system. We look forward to hearing from individuals who wish to make a personal contribution to achieving a society with zero environmental impact.

Aiming for a society with zero environmental impact through the implementation of space solar power

"Space solar power" is a groundbreaking technology for stable generation of power day and night. We are developing new laser-based technologies that will make it possible to implement space solar power. We aim to apply space solar power to a wide range of future applications in space, such as power supply between satellites and on the surface of the moon in the shade of the sun. Space solar power will not only solve energy problems on Earth but also contribute to space exploration and the expansion of humanities' living space. So we invite you to join us in building a sustainable society with zero environmental impact through the implementation of space solar power.
