低温固体氧化物燃料电池法开采天然气水合物

Exploitation of Natural Gas Hydrate by Low Temperature Solid Oxide Fuel Cells Method

热开采法、抑制剂刺激法等传统天然气水合物开采方法将破坏水合物地层,不能有效地解决海底地层破坏和开采使用化石燃料燃烧后所存在的碳储存和碳捕捉问题。介绍了低温固体氧化物燃料电池法开采天然气水合物的方法。该方法利用CO2置换天然气水合物地层中的甲烷,运送到低温固体氧化物燃料电池的阳极,在阴极通入空气,发生电化学反应,产生电能,并将产出的CO2通入到天然气水合物地层,置换出甲烷。该方法简单、实用,克服了传统开采方法所存在的问题,发电效率较传统发电方法大幅提高。

Nowadays,with the increasing greenhouse effect,all the countries of the world are controlling CO2 emission strictly.Simultaneously,because of the bonding effect of Natural Gas Hydrate（NGH） in the submarine formation,the previous methods of heating or stimulating by inhibitors will not fit for the exploitation of NGH from the sea floor,nor suitable for the problem resolution of the damage of submarine formation,carbon dioxide storage and carbon capture.This article describes a new NGH exploring method by low temperature solid oxide fuel cell.In this method,CO2 replaces methane of NGH,and air pump delivers methane into the anode of LTSOFC.Meanwhile,the air pump in the ground delivers air into cathode of LTSOFC,making them occur electrochemistry reaction and generate electric energy,then pumping the output（CO2）into NGH formation.This new method is practical and simple,and overcomes the setbacks of the traditional production methods.Comparing with the traditional methods of power generation,this new method improves the generating efficiency.
