Existing infrastructure could be used to store surplus renewable electricity as synthetic natural gas (Image: Fletcher6 via Wikipedia Commons)
The use of environmentally friendly wind and solar energy is on the rise throughout the world, but the problem with such energy sources is their unreliability. Depending on the weather or time of day (or more specifically, night) the amount of electricity generated may be deficient or surplus to current requirements. Storing surplus energy in batteries for later use is one solution, but now researchers are developing a way to store surplus renewable electricity as natural gas.
