All hydrogen-powered fuel cells are 'hydrogen powered electrical generators'. To be classified as 'renewable energy', the hydrogen must come from a renewable source. Splitting water with solar electricity to generate hydrogen to burn in a fuel cell is renewable. Converting coal, oil or natural gas to CO2 and hydrogen and burning that hydrogen in a fuel cell to generate electricity (follow?) is NOT renewable, and increases global warming due to atmospheric input of CO2, and yes, the science of global warming is well-understood. Generating hydrogen from geothermal sources that generate electricity to split water to form hydrogen to burn in a fuel cell seems redundant, but the point is that hydrogen is easier to store by far then electricity - which is why Iceland has hydrogen filling stations now. This strategy IS renewable, although pollution is always a factor, even in renewables (solar cell plants, ethanol plants, etc. all produce pollution if not properly designed). The bottom line here is that a tank of fuel is more easily transported and stored then electrical charge is. This business of the conversion of light energy and heat energy to electrical energy and chemical energy is the fundamental physical basis of all renewable energy strategies. This is exactly what green plants do in the course of photosynthesis, at the atomic/molecular level.
