Pardon me while i butt-in.

Years ago I was thinking about retiring onto a houseboat. The roof would be solar panels. The engines ICE-electric. My thinking was like this.

The solar panels create DC. Use the DC current to charge some storage cells. Use the cells to separate 2(O2) from H2 through electrolysis. Use the DC current to run an H2 compressor, exhaust the O2 into the water (and into the bubble tank for my fish).

Run the ICE engine off of H2. The ICE drives a generator for both service and propulsion.
