After struggling to read the linked source paper, it kind of sounds like a heat battery.

You create a reversible reaction to store and release heat with electricity.

The image shows a solution being moved from a hot side to a cold side, but instead of using pressure to store and release heat, you use a chemical reaction.

Was hoping this would not require moving parts, but it might be better that it does, because you can move the heat further with high efficiency this way. Maybe even a better way to use geothermal energy to move heat.
