Ideally, most of the world wants to transition to renewable energy to reduce our dependence on energy sources that aren't so great for the environment and to move to energy sources that won't really run out any time soon.
Solar power is certainly on that list of potential candidates, however the only problem with solar power is that only one half of the Earth can get sunlight at any time of the day, which means the other half is left without a means of getting power until the Sun rises again. This is where batteries and forms of energy storage come into play.
While batteries are currently the main form of battery storage today, they're not really what we might call "efficient." On the other hand, some researchers have come up with a way to store solar energy inside of a liquid.
When the liquid is exposed to light, it becomes an isomer and stores energy, which when released with a catalyst, can be harnessed as either heat or energy. This liquid storage technology has the potential to be a real game-changer in the solar power industry, and it ought to be interesting to see what becomes of it.
