Passage 1.(2021•宜昌模拟)
Zero﹣emission(零排放) large passenger aircraft powered by hydrogen will be technically possible in five years, according to Airbus, but they will not enter service for at least a decade as the price of the fuel needs to come down.
The prediction comes from Glenn Llewellyn, vice﹣president of zero﹣emissions technology at the pan﹣European plane﹣maker. He said that while Airbus planned to demonstrate hydrogen﹣powered aircraft in 2025, over the next 10 years, hydrogen won't be more economical than the fossil fuel.
For passengers to be flying genuinely emissions free aboard hydrogen﹣powered planes ﹣ which emit only water and heat ﹣ their fuel needs to come from hydrogen produced via renewable sources such as wind and solar, he added.
In an interview ahead of the Bloomberg NEF London Summit, Mr. Llewellyn said, "We already see massive increases in the amount of renewable energy being produced across the world. Wind energy production has multiplied by two over the last five years and solar energy production has multiplied by four."
A further challenge is building up the ecosystem that hydrogen aircraft, along with other forms of transport, will need. This ranges from creating the fuel from electrolysis(电解) to split water into hydrogen and oxygen powered by renewable energy, to the actual transport of the gas and fueling systems for it at airports.
However, Mr. Llewellyn predicted that there was enough interest in the sector to make this happen. He added, "There are a number of independent institutes that have mapped out how hydrogen costs can come down over the next decades. We see a 30pc reduction in renewable hydrogen costs in 2030 compared to where it is today, and a 50pc reduction in renewable hydrogen costs by 2050."

A. It will be an unrealistic dream. B. The cost of its fuel keeps rising.
C. It will
