I don’t know what depths we’re talking about here,

From the article:

The idea is relatively simple: hollow concrete spheres are installed at a depth of several hundred metres.

Thanks, I missed that on my read through - 1000 feet of water is pretty serious pressure.

The more pressure the more "equivalent head" power discharge potential. Separate "vacuum pump" (instead of bidirectional) could also have several stages to improve efficiency.
