Losing Earth's hydrogen to space would require a stupendously long wait. Maybe freeing all of it at once would help speed the process asking, but the first lightning strike, volcanic eruption, or meteor would just ignite it all back to water. I'd be far more worried about getting struck by lighting, a volcanic eruption or a meteor, than losing our hydrogen to space.
