The hydrogen could then be burned or converted to electricity in a fuel cell. in this use case would almost certainly end up released to the atmosphere. We recently discussed a case where.

Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. Cellular respiration is considered an exothermic redox reaction which releases heat. The overall reaction occurs in a series of biochemical steps, most of which are redox reactions themselves.

When doing so, the bond – which stores a great deal of potential energy – is dissociated, converting the potential energy into kinetic energy. This energy is used to fuel endergonic chemical reactions.
