Hydrogen is not source of power unless you are doing hydrogen-related research and this gives you power in the organization you work for. Power is rate of energy transfer. https://en.wikipedia.org/wiki/Power_(physics) https://en.wikipedia.org/wiki/Power_(physics) You would not typically call something "source of power". Rather, we would typically discuss "source of energy" which is then converted to power by expending it (transferring/converting) at different rates depending on application (think in terms of your power at your academia letting you force undergraduates doing work for you). As to sources of energy, the only way hydrogen can be used as a source of energy is through fusion which is currently unattainable on commercial scale in 10 years. There are also no sources of hydrogen that can be mined or otherwise exploited on Earth. There exist, arguably, fossil fuels that are rich in hydrogen. A cell using such a fuel could technically be called hydrogen fuel but in normal use they are typically called cars.
