Captured CO2 Could Fuel a Giant Underground Battery | Ethics Asylum

Carbon dioxide generated by burning fossil fuels and other human activities is a big problem, when it comes to climate change.  But researchers say that it actually may be possible not only to capture and store CO2 in the ground, but to transform it into the equivalent of a battery that would store energy from renewable sources and solve the supply fluctuations that hinder them as a replacement for coal.
