Twenty-Four-Year-Old CAES Innovator Making Good Progress
At the age of 24, Danielle Fong, founder of LightSail Energy in Berkeley, California, is breaking new ground.
While reading, an idea hit her: spraying water into the air to cool it. How this applies to Compressed Air Energy Storage (CAES), her field of expertise, is to use the heated water to minimize energy loss.
Her CAES system is able to reuse up to 70 percent of the total energy it stores, an efficiency that matches the best batteries in the market.
Fong has also been able to find a compound that stores compressed air more efficiently than steel. Tanks made of such a material need not be stored underground. In addition, it will be relatively easier to build storage facilities large enough to power cities, she notes.
If you want to know more about this and other topics directly from end users of energy storage technologies join us at one of these annual events: The Energy Storage World Forum (Grid Scale Applications), or The Residential Energy Storage Forum, or one of our Training Courses.
