Yes, but if it could provide as an alternative to digging up oil and gass, and get the energy needed to make the transformation from sun, wind or other sustainable sources. It could lower the amount of new CO2 being put into the atmosphere as well as work as a way to store excess energy from wind and sun.

Yeah, it would basically act as a battery except much better energy and power density, and faster 'charging'.

The downside is invariably that round trip energy efficiency (electricity in vs electricity out) is somewhere between 'much worse' and 'terrible'.
