It is disclosed a system for producing methanol/methane, said system comprising an electrolysis section (1) producing hydrogen and oxygen from the cleaving of water molecules, and said system further comprising a closed cultivation/breeding container/pond (5) for aquatic organisms creating CO2 through their metabolism to be liberated into the water surrounding said organisms forming CO2-rich water, said CO2-rich water being transported to a CO2-liberating section forming gaseous CO2 and CO2-poor water, said liberated gaseous CO2 being transported to a reactor (6,6′) and being combined with said hydrogen from said electrolysis plant (1) for creating methanol and/or methane as an end product, said methanol/methane being isolated and exited from said system.
A system for producing methanol/methane, said system comprising:

The present invention relates to a process for producing methanol and/or methane by using carbon dioxide sequestered from dissolved carbon dioxide in water taken or isolated from a land-based plant for raising or farming aquatic animals such as fish combined with hydrogen originating from electrolysis of water through the reactions (I) or (II)
CO2+3H2=>C3OH+H2O (I)
CO2+4H2=>CH4+2H2O (II)
The present invention will become better understood with reference to the enclosed FIGURE showing an embodiment of a system according to the present invention combining the formation of oxygen 2 and hydrogen 3 from electrolysis 1 of water wherein CO2 is isolated 4,4′ from the water taken from used water including entrained CO2 from a cultivation/breeding tank/pond 5 for aquatic animals/fish. The isolated CO2 is reacted with hydrogen originating from the electrolysis 1 of water forming methane and/or methanol 6,6′ as explained supra. In one embodiment the methane may be supplied to a bacterial culture 8 as a growth substrate for creating protein to be used in e.g. fish feed. Such protein may in one embodiment constitute about 30% of protein included in such fish feed.
In an alternative embodiment methanol created by the process according to the invention may be used as a starting material for making more complex substances (e.g. plastics, oil, etc.) or may be used as a fuel or a fuel additive.
In one embodiment hot water used in the system according to the invention may be supplied from an external source or may be water recirculated from the cultivation/breeding tank 5. In an alternative the CO2-poor water from the carbon dioxide-extracting section 4 may be supplied with oxygen 2 originating from the electrolysis section 1 of the system according to the invention and be returned in an oxygen-rich state back to the cultivation/breeding tank/pond 5. This is indicated by a dotted line 7 running from the carbon dioxide removal stage 4 to the supply line 2 carrying oxygen from the electrolysis stage 1 to the cultivation/breeding tank/pond 5.
