The other option is nuclear which has the huge upfront cost and nuclear waste, but with minimal global warming.
I don't see why the various battery types aren't practical today. Unlike nuclear, there's no huge political resistance and once solar and wind are online, investment in energy storage becomes online energy fairly quickly. Moreover, the huge energy include huge uncertainties, uncertainties whether the plant will shutdown early, especially.
Remember, the huge upfront costs of nuclear includes energy expenditure and as you're pointing out, expending more energy means more global warming until we have fully replaced fossil fuel.
Long ago, solar and wind advocates were derided for contrasting hypothetical ideals with current realities. Nuclear proponents now seem much closer to doing that.
