Hydrogen : How to make it on Electrolysis of water - Wikipedia
Two leads, running from the terminals of a battery, are placed in a cup of water with a quantity of electrolyte to establish conductivity in the solution.
Using NaCl (table salt) in an electrolyte solution results in chlorine gas rather than oxygen due to a competing half-reaction. With the correct
electrodes and correct electrolyte, such as baking soda (sodium bicarbonate), hydrogen and oxygen gases will stream from the oppositely
charged electrodes. Oxygen will collect at the positively charged electrode (anode) and hydrogen will collect at the negatively charged
electrode (cathode). Note that hydrogen is positively charged in the H2O molecule, so it ends up at the negative electrode. (And vice versa for oxygen.)
Below is an example of a hydrogen solar farm by Belgian company Tiger power (https://twitter.com/Tigerpower_eu?s=20 )
Note: I have contacted Tiger power for confirmation on product as website is not live, awaiting reply.
It uses excess power from solar to make hydrogen and store it to run generators when not enough solar is available, at night etc.
The same concept could also be powered by wind and wave farms in N. Ireland.
In simple terms it just transforms live power 'electricity' into potential energy gasses hydrogen and oxygen by electrolysis with water,
that can be combusted in an internal combustion engine to power machines or drive a generator going back to electricity.

Solar Hydrogen Production: Processes, Systems and Technologies presents the most recent developments in solar-driven hydrogen
generation methods. The book covers different hydrogen production routes, from renewable sources, to solar harvesting technologies.
Sections focus on solar energy, presenting the main thermal and electrical technologies suitable for possible integration into solar-based
hydrogen production systems and present a thorough examination of solar hydrogen technologies, ranging from solar-driven water electrolysis
and solar thermal methods, to photo-catalytic and biological processes. All hydrogen-based technologies are covered, including data regarding
the state-of-the art of each process in terms of costs, efficiency, measured parameters, experimental analyses, and demonstration projects.
In the last part of the book, the role of hydrogen in the integration of renewable sources in electric grids, transportation sector, and end-use
applications is assessed, considering their current status and future perspectives. The book includes performance data, tables, models and
references to available standards. It is thus a key-resource for engineering researchers and scientists, in both academic and industrial contexts,
involved in designing, planning and developing solar hydrogen systems.

The hydrogen would be mixed with the air in the intake manifold in an internal combustion engine.
The hydrogen tank would need a pressure escape valve as hydrogen expands from liquid at low temperatures.
You would probably need a butterfly valve on the exhaust to bypass the catalatic converter as does not like water.
