First of all, to have any hope of of reducing global warming to mild proportions, energy usage will have to shrink, and so will the economy. We are simply too far advanced for any green energy solution and magical carbon sequestration to be able to help in time while also growing the global economy. Since we also want the global south to reach decent levels of development, the rich countries will have to accept even more shrinkage in their economy to accommodate rising consumption in the poorer ones - especially those hurt the most by the last few centuries of industrial progress.
This shrinkage will happen either way, due to the effects of global warming in theatter half of this century - today, we still have an option of doing it in a somewhat controlled manner. Tomorrow we will not.
Secondly, it is important to realize that it is theoretically impossible, not just technologically, to produce a battery that has the energy density of gasoline or most fossil fuels. The best realistic batteries we can think of are about 6MJ/kg, compared to 44-50 MJ/kg for hydrocarbons. This also means that transportation will become much more expensive in the coming decades, especially for goods - a battery powered cargo ship will transport ~10 times less cargo per journey than today, and so will an electrical truck (though the truck would likely be replaced by rail transport).
