It's looking like another step toward Hydrogen batteries.

There are some people working on hydrogen fuel cells for multirotors but they have some way to go before we are likely to see a hydrogen powered consumer multirotor.They are flying but they are not compact and look a bit ungainly but the flight times are impressive even though most of the 45 minute plus flights are only hovering.
There are a few videos on youtube showing where the technology is at.

This one looks good but it's huge in comparison with most of the multirotors we play with.
