在飞机日益成为普遍的出行工具之际,航空污染也越来越受到重视。有专家提出,航空业碳排放是雾霾天气的重要诱因。如何找到真正环保的飞机动力来源,不仅是全球的共同挑战,也是事关人们呼吸的民生问题。通过各国政府和企业的不懈努力,目前已找到几种可能替代航油的清洁能源。其中,氢和电是被最广泛提及的。那么,氢动力飞机和电动飞机的前景如何?在商用化道路上,又存在着哪些困难?绿色飞行时代到底离我们还有多远?
As airplanes increasingly become universal travel tools, aviation pollution is gaining more and more attention. Some experts have suggested that aviation industry carbon emissions is an important incentive for smog weather. How to find a truly environmentally-friendly source of aircraft power is not only a common global challenge, but also a matter concerning people’s livelihood that people breathe. Through the unremitting efforts of governments and enterprises in various countries, several clean energy sources that may replace aviation fuel oil have been found so far. Among them, hydrogen and electricity are the most widely mentioned. So, the prospects for hydrogen-powered aircraft and electric aircraft? In the commercialization of the road, what are the difficulties? Green flight era in the end we are far in the end?
