Sure, hydrogen is not good compared to batteries as an energy storage medium, but making synthetic fuels from solar power is also massively inefficient. Biofuels is a huge waste of farmland, fertilizer, etc. This downside compared to batteries is why hydrogen will not be used in cars or boats, but the weight of hydrogen is a big enough advantage that it will probably be used in medium haul planes. Long haul planes will probably rely on biofuel or synfuel, but zeroavia.com claims they'll get to 5000 nm range eventually.
