Pure hydrogen is heavy greenwashing - after many years talking about green generation, still over 90% is created from natural gas, by the usual fossil fuel companies; they are also the ones promising to build the green hydrogen factories, by the way. It is indeed barely suitable for (direct) consumer use and highly inefficient for electricity generation (like 10% efficiency iirc).

Long duration energy storage efficiency with hydrogen is closer to 40-45%. It is feasible and a good option in certain grid applications.
