The electricity in the process is primarily used to generate hydrogen, which is what actually feeds the yeast cells. Even a fairly small buffer tank would allow for continuous production with unreliable power. My guess is that food production can also be slowed down if hydrogen production slows down. Storing hydrogen as food is fantastic, since food can be stored much less expensively than gaseous or liquid hydrogen and for much longer periods of time.
