상술한 바와 같이, 수소를 액상유기물과 결합시켜 액상유기화합물 형태로 변환시킨 상태에서 해저저장부(190)에 저장하게 되므로, 해상의 선박 등에 원활한 수소 연료 공급이 가능하다. 또, 수소가 공기에 누출되어 폭발할 수 있는 가능성을 제거할 수 있다.As described above, hydrogen is combined with liquid organic matter and converted into a liquid organic compound form and stored in the
구체적으로, 해저저장부(190)에 저장된 액상유기화합물에 함유된 수소는 다양한 수요처로 공급될 경우, 열에너지 및 촉매 등에 의해 다시 방출될 수 있고, 선박 등의 수소 연료로 공급될 수 있다. 예컨대, 연료가스 중에서 널리 이용되고 있는 천연가스(Natural Gas)는 메탄(Methane)을 주성분으로 하며, 통상적으로 그 부피를 1/600로 줄인 액화가스(Liquefied Gas) 상태로 변화되어 저장 및 운반되고 있다. 천연가스는 석유 연료보다 탄소 성분이 적어 탄소계 유해배기가스의 배출은 적으나, 좁은 가연 한계, 느린 연소 속도 등으로 연소가 불안정하다. 반면, 수소는 연소 속도가 빠르고 가연 한계가 넓어서 안정적으로 운전이 가능하고, 연소 반응에 의해 이산화탄소가 발생하지 않는다. 따라서, 해저저장부(190)에 저장된 액상유기화합물에 함유된 수소를 다시 방출시켜, 천연가스와 적절히 혼합한 후, 선박의 엔진 연료로 공급하는 등 다양한 수요처에 다양한 방법으로 연료 공급이 이루어질 수 있다.Specifically, when the hydrogen contained in the liquid organic compound stored in the
