Current solar energy storage solutions can only store energy for a few hours. Replacing baseload fossil fuel plants with solar will require effective long-term storage.
TECHNOLOGY SOLUTION
Planet A's SunVise product uses breakthrough optics to capture massive amounts of solar energy directly into a vast bed of black sand, storing weeks or months of energy as heat in a combined collection and storage system. The black sand material costs 1/100 as much as batteries, never wears out, and is non-toxic and readily available.
