Method and apparatus for producing methanol making use of biomass material

An apparatus for producing methanol making use of biomass material comprising:

• biomass gasification means for producing a gas through partial combustion or steam-gasification of biomass;
• methanol synthesis means for producing methanol from the thus-produced gas,
• hydrogen gas supplying means for supplying hydrogen gas to the produced gas, wherein the hydrogen gas supplying means supplies hydrogen gas to the produced gas such that the amount of hydrogen gas is adjusted to at least twice the amount of carbon monoxide contained in the produced gas and wherein the hydrogen gas supplying means includes water electrolysis means for electrolyzing water wherein oxygen gas generated through electrolysis of water by means of the water electrolysis means is supplied, as a gasification agent, to the biomass gasification means;
• oxygen gas reserving means for temporarily reserving oxygen gas generated through electrolysis of water by means of the water electrolysis means, wherein the hydrogen gas supplying means includes hydrogen gas reserving means for temporarily reserving hydrogen gas generated through electrolysis of water by means of the water electrolysis means;
• and
• natural-energy-based power-generation means for operating the water electrolysis means through power generation making use of natural energy.
