PROBLEM TO BE SOLVED: To provide an energy conversion system for coping with suppression of global warming, fossil fuel depletion, and overall, efficiently coping with the problem such as an increase in food production.SOLUTION: A biomass energy conversion system is used to increase a power generation amount by: installing a device which partially burns a wooden material to gasify the same in juxtaposition with a device which subjects animal and vegetable wastes as the raw material to methane fermentation to feed excess heat from the former to the latter； generating power, when power demand is high, on burning with both generated gasses combined； reserving the methane fermentation gas, when the power demand is small, to carry out the methane fermentation processing of organic wastes by using methane fermentation fungi where a spawn, a substance serving as the bate, and terahertz waves are added to a liquid to carry out fermentation； and activating water by using power, when the power demand is small, to produce activated water, hydrogen gas, and oxygen gas, and to add a part of the oxygen gas and hydrogen gas via a reservation device to a device which generates power on burning.SELECTED DRAWING: Figure 1【課題】地球温暖化抑制、化石燃料枯渇への対応、食料増産などの課題に総合的、効率的に対応するためのエネルギー変換システムの提供。【解決手段】木質原料を部分燃焼してガス化する装置と動植物系廃棄物を原料としてメタン発酵する装置を併設し、前者から後者に余熱を供給すること、電力需要が高い時には、両者の発生ガスを合わせて燃焼して発電し、電力需要が小さい時には、メタン発酵ガスは貯留し、有機系廃棄物のメタン発酵処理を、液に種菌、その餌となる物質、さらにテラヘルツ波を加えて増殖を行ったメタン発酵菌類を用いて行い、電力の需要が少ない時は、電力を用いて水の活性化を行い、活性水、水素ガス、酸素ガスを製造し、酸素ガス及び水素ガスの１部は貯留装置を経て、燃焼して発電を行う装置に加えることによって、発電量を増加させることに用いるバイオマスのエネルギー変換システム。【選択図】図１
