The present invention provides an integrated process for producing a fermentation product from fossil carbon and hydrogen present in a purge gas stream resulting from a hydrogen production process. According to one embodiment of the invention, a purge gas stream obtained from a hydrogen production process is fermented with microorganisms in one or more bioreactors to produce the fermentation product. A fermentation exhaust gas stream from the one or more bioreactors comprising hydrogen, carbon monoxide and/or methane is then obtained and heat is generated therefrom to provide energy for the hydrogen production process.
