1. A method for making a bio-based product, the method comprising:
introducing H2 gas into a gas reactor chamber of a bioreactor in fluid communication with a first side of a biomaterial reactor chamber containing biomaterial to form a gas phase;
introducing medium containing O2 into the bioreactor on a second opposite side of the biomaterial reactor chamber to form a medium phase, the biomaterial reactor chamber comprising a membrane that provides a seal between the gas phase and medium phase;
introducing CO2 into the bioreactor on the first side, the second side, or both, wherein the biomaterial produces the bio-based product from the H2, the CO2, and the O2;
outletting the bio-based product from the bioreactor; and removing the H2 gas from the gas reactor chamber through a gas outlet manifold and a gas outlet,
wherein gas and medium reactor chambers are on each side of bioreactor chamber so that gas may be supplied on one side of the biomaterial reactor through a gas inlet, the gas passing across biomaterial and exiting the bioreactor at an opposite end through a gas outlet, and medium may be supplied to the bioreactor from a side adjacent to the gas inlet, the medium supplied through a medium inlet passing across the biomaterial and exiting the bioreactor at an opposite end through a medium outlet.
 
5. A method for making a bio-based product, the method comprising:
introducing H2 gas into a gas reactor chamber of a bioreactor in fluid communication with a first side of a biomaterial reactor chamber containing biomaterial;
introducing medium containing O2 into the bioreactor on a second opposite side of the biomaterial reactor chamber;
introducing CO2 into the bioreactor on the first side, the second side, or both, wherein the biomaterial produces the bio-based product from the H2, the CO2, and the O2;
outletting the bio-based product from the bioreactor; and removing the H2 gas from the gas reactor chamber through a gas outlet manifold and a gas outlet,
wherein the bioreactor comprises: a manifold plate having a gas inlet, a gas outlet, a medium inlet, and a medium outlet; a gas delivery plate having a gas reactor chamber, a gas inlet manifold in fluid communication with the gas reactor chamber, a gas outlet manifold in fluid communication with the gas reactor chamber, a medium inlet manifold in fluid communication with the medium inlet, and a medium outlet manifold in fluid communication with the medium outlet; a biomaterial plate having the biomaterial reactor chamber, a gas inlet manifold in fluid communication with the gas delivery plate gas inlet manifold, a gas outlet manifold in fluid communication with the gas delivery plate gas outlet manifold, a medium inlet manifold in fluid communication with the gas delivery plate medium inlet manifold, and a medium outlet manifold in fluid communication with the gas delivery plate medium outlet manifold; a medium delivery plate having a medium reactor chamber, a gas inlet manifold in fluid communication with the biomaterial plate gas inlet manifold, a gas outlet manifold in fluid communication with the biomaterial plate gas outlet, a medium inlet manifold in fluid communication with the medium reactor chamber and the biomaterial plate medium inlet manifold, and a medium outlet manifold in fluid communication with the medium reactor chamber and the biomaterial plate medium outlet manifold; and an end plate.
