As an idea it goes me back to ~ 2014
Conventional vacuum micro-waves generators are characterized by very high energy efficiency of industrial quality electricity transforming into electromagnetic field at normal operational conditions (up to 80% for industrial quality samples) and can produce EM-energy up to many Megawatt in pulse of tens or hundreds kW average.
It allows to use the EM energy concentrating on a small spot under the water surface, on the small target to reach about 2500 Centigrade being enough to split the water on hydrogen and oxygen, the both are instantly cooled down to normal temperature by surrounded water, isn't needed to be distillate, and any water vessel can be a cheap plastic.
Input electricity can be USD 0.001-0.002/kWh or even cheaper, and the electricity can be renewable electricity of any supply schedule up to round-the-clock and all-year-round. [1] So the water splitting in 1 kg of hydrogen and 8 kg of oxygen consumes about 40 /0.8 = 50 kWh electricity by USD 0.05-0.1 or less. The said EM energy generators usually are quite simple and cheap devices by its mechanics point of view, and can be about USD 40/kW or so.
So that only sufficient part of total capital cost adds (USD 40 /(8766 hour * 5 years of payback) * 50 kWh = USD 0.046. and in sum USD 0.096 – 0.146 for 1 kg hydrogen production with 8 kg oxygen free.
