For long term energy storage, minimizing the capital cost of energy storage capacity is paramount. Round trip efficiency is not.
On that relevant metric, hydrogen is very hard to beat, particularly if proper geology is available (salt formations for solution mined storage cavities). Costs less than $1/kWh are possible.
Artificially heated geothermal may be competitive on that metric, but its RTE is likely to be even lower.
