Scuba tanks only go up to 5.5ksi. I think you’d need more like composite over wrapped pressure vessels (COPVs) for 10ksi. Those are relatively new even in spaceflight. SpaceX discovered some new physics when their AMOS-6 mission exploded on the launch pad in 2016 due to oxygen freezing inside the composite layers.
