Natural gas isn't renewable, but a natural gas infrastructure can actually contribute towards solving the energy storage problem. The idea is that surplus electricity from renewable energy is used to create hydrogen which is added to the natural gas grid and burned later in gas turbines when the demand exceeds the supply of renewables. A significant amount of hydrogen can be mixed in with natural gas without issues. For the longer term, people are also working on generating methane (CH4), which is the main component of natural gas, from electricity and CO2. Burning that would be carbon neutral as well.
