LightSail Energy

These Are the 30 People Under 30 Changing the World

Danielle Fong, the founder and chief scientist of LightSail Energy, has been searching for a solution to the world’s energy challenges since she started a Ph.D. at Princeton at age 17. LightSail’s compressed air energy storage system could solve the intermittency problem that plagues wind and solar power plants (no power when it’s dark or windless) by storing energy for use later in the form of highly-compressed, clean air.
