It will be safer as it carries a very small inventory of hydrogen. A small high pressure electrolysis unit producing only enough to fill the 50mL reactor to 20bar means perhaps 0.1grams total inventory - about 12kJ in case of a fire or explosion - ie about the same as a 50 calibre machine gun bullet. This means little to no danger from leaks. Avoidance of handling and storing large hydrogen vessels should also be a big cost and safety improvement - typical high pressure gas tank rental costs amount to $50-100 per year.
It is also not sensible to make judgements about safety and cost of a small electrolysis unit based on current 1000's per year production numbers when we are discussing solutions for 100's of millions of units - they will be dirt cheap and super-reliable at that stage.
