Although this link doesn't mention this, I think one thing that makes this type of renewable energy very attractive is that there is no need for off-the-grid energy storage for this type because you can simply enough control power output by controlling fluid flow rate through the boreholes.
For this reason, I think this could complement solar and wind energy very well because it could be powered up when there is little sun or wind and powered down when there is plenty of solar and wind and thus reduce the required amount and therefore the total cost of off-the-grid energy storage.
I definitely think a lot more research should be done into this.
