The Data Center Boom Is Fueling The Space Solar Race

The article discusses the emerging intersection of space-based solar power and the growing demand for energy by orbiting data centers, driven largely by the AI boom. Space solar power, once a futuristic concept, is gaining traction as a viable energy source due to its ability to provide continuous, high-capacity solar energy without the limitations faced on Earth such as day/night cycles, weather, and permitting delays. The Washington-based startup Lumen Orbit (now rebranded as Starcloud) highlights that solar arrays in space can achieve over 95% capacity factor and generate more than five times the energy compared to terrestrial solar farms, thanks to the absence of atmospheric interference and constant sun exposure. Starcloud, backed by NVIDIA through its Inception program, aims to leverage these advantages to power data centers in orbit, offering significant sustainability benefits including a tenfold reduction in carbon emissions over the data center’s lifetime and eliminating the need for water-based cooling and energy storage systems. The company plans to launch its first satellite, Starcloud
