空中客车推迟氢动力飞机的研发
📖 逐句对照翻译
European manufacturer Airbus has announced a delay in its development efforts of a hydrogen-powered aircraft.
欧洲制造商空中客车公司宣布其氢动力飞机的研发工作出现延迟。
The company explained that progress on the project has been slower and more complex than expected.
公司解释说，该项目的进展比预期更慢、更复杂。
Airbus had set a goal to make a zero-emission airplane by 2035.
空中客车公司设定了到2035年制造零排放飞机的目标。
The company has not announced a new target date for the plane’s production.
该公司尚未公布该飞机生产的新目标日期。
But the French union Force Ouvrière said some of its aircraft workers were recently told the technology was running five to 10 years behind, Reuters news agency reported.
但据路透社报道，法国工会“工人力量”表示，其部分飞机工人最近被告知该技术落后五到十年。
The French news agency AFP reported Airbus also said it had reduced the program’s budget by 25 percent, but was still examining ways to reduce emissions.
法国新闻社法新社报道，空中客车公司也表示已将该项目的预算削减了25%，但仍在研究减少排放的方法。
"Our ambition and roadmap towards decarbonizing. . .remain unchanged," an Airbus spokesman told AFP.
空客发言人向法新社表示：“我们脱碳的雄心和路线图……保持不变。”
In September 2020, Airbus presented three hydrogen-fueled airplane designs, called ZEROe, as part of its efforts to decarbonize.
2020年9月，空中客车公司展示了三款氢燃料飞机设计，名为ZEROe，作为其脱碳努力的一部分。
Other airplane manufacturers, however, have centered more on renewable fuels or developing electric-powered planes for short-distance flights.
然而，其他飞机制造商则更多聚焦于可再生燃料或开发用于短途飞行的电动飞机。
Airbus noted it has no plans to completely stop developing hydrogen-powered aircraft technology.
空中客车公司指出，它没有计划完全停止开发氢动力飞机技术。
The company said it sees hydrogen as “a revolutionary energy source for aviation.
该公司表示，它将氢视为“航空领域的革命性能源”。

However, Airbus said in a statement to Reuters it recognizes that developing systems to produce, transport, and store hydrogen represent “a huge challenge requiring global collaboration and investment.
然而，空中客车公司在给路透社的一份声明中表示，它认识到开发生产、运输和储存氢气的系统是一项“需要全球合作和投资的巨大挑战”。

Difficulties with hydrogen
氢的困难
Hydrogen motors do not release gases that can warm the earth’s atmosphere.
氢动力发动机不会释放能使地球大气变暖的气体。
Instead, they release water.
相反，它们释放水分。
However, much of the hydrogen used for fuel is produced using natural gas or coal.
然而，用于燃料的氢气大多是通过天然气或煤炭生产的。
Both of these production methods often release carbon dioxide gas, which can warm the atmosphere.
这两种生产方法通常都会释放二氧化碳气体，从而可能导致大气变暖。
Running renewable electricity through water can produce hydrogen without adding to carbon emissions.
利用可再生电力电解水可以生产氢气，而不会增加碳排放。
However, this process is generally more costly.
然而，这一过程通常成本更高。
Transporting and storing hydrogen also present problems.
运输和储存氢气也存在问题。
As a gas at room temperature, hydrogen takes up a very large space.
作为室温下的气体，氢气占据非常大的空间。
This makes it impossible to use as fuel.
这使得它无法用作燃料。
It first needs to be turned into a liquid to be transported or stored.
首先需要将其转化为液体以便运输或储存。
And it needs to be cooled to -253° Celsius to be liquefied.
并且需要冷却到-253摄氏度才能液化。
This cooling process requires its own source of energy.
这个冷却过程需要自己的能源。
Liquified hydrogen still takes up four times the space of jet fuel.
液态氢占用的空间仍然是喷气燃料的四倍。
The airline industry trade association IATA believes aviation will reach most of its reduction in emissions by using sustainable aviation fuel (SAF).
航空业贸易协会国际航空运输协会认为，航空业将主要通过使用可持续航空燃料（SAF）来实现大部分减排目标。
It believes other technologies, like hydrogen, will take longer to develop.
它认为其他技术，如氢能，将需要更长时间来发展。
SAF uses food and plant waste from cities, agricultural and forest wastes, and other non-petroleum sources.
可持续航空燃料使用来自城市的食物和植物废料、农业和林业废弃物以及其他非石油来源。
This fuel is then added to jet fuel in mixtures of 10 to 50 percent to become SAF.
这种燃料随后以10%至50%的比例与航空燃油混合，制成可持续航空燃料。
Airbus says it agrees that SAF can also play an important part in reducing emissions, particularly for medium and long-distance flights.
空中客车公司表示，它同意可持续航空燃料也能在减少排放方面发挥重要作用，尤其是对于中长途航班而言。
