剧情介绍:



According to Xinhua News Agency,real time news on November 28th, British Virgin Atlantic launched the world's first transatlantic flight using "sustainable aviation fuel" (SAF). According to its official introduction, the fuel used in the flight is mainly extracted from waste edible oil and animal fat, and the synthetic aromatic kerosene made from discarded corn is mixed, and its carbon emission is 70% less than that of fossil fuels.

According to the report, on the first flight day, Virgin Atlantic founder richard branson and CEO Shay Weiss took the flight from London and landed at Kennedy International Airport in new york that afternoon, with no paying passengers on board. The aircraft model is Boeing 787. Different from traditional flights, the passenger plane uses "Sustainable Aviation Fuel" (SAF), which is made of waste cooking oil, animal fat and sugar, and also includes corn and municipal garbage, and its carbon emission is 70% less than that of fossil fuels. At present, the output of this fuel only accounts for 0.1% of the total aviation fuel consumption in the whole market, but experts predict that SAF will play an important role in the "zero carbon emission" transformation of the aviation industry in the future.

Because the cost is too high and the output is too small, this "100%SAF" passenger plane is only a "gimmick" at present and cannot be promoted. Although it can reduce carbon emissions by half on average compared with traditional fuels, unless breakthroughs are made in technologies such as batteries and liquid hydrogen, SAF alone cannot achieve real "zero carbon emissions". Some European airlines, such as Virgin Atlantic, British Airways and Air France, said that they hope to increase the proportion of sustainable aviation fuel SAF in their aircraft fuel to 10% by 2030. However, if the aviation industry wants to achieve the goal of net zero emission in 2050, it needs to increase this ratio to 65%.
