The world's first hydrogen-powered trains have been unveiled in Germany.They began carrying passengers in Germany's northwestern Lower Saxony state.The new trains will run 100-kilometer trips and can travel up to 140 kilometers an hour.

A French railroad company called Alstom rolled out the two trains.Teams in Germany and France worked in collaboration on the project which was approved by the German government.The new train model,called the Coradia iLint,signifies the beginning of efforts in Germany and other nations to seek an alternative to pollution-producing diesel (柴油)trains,the number of which in circulation is still high.

The Coradia iLint is designed to run on non-or-partially-electrified train lines with low levels of noise.It uses a process that combines hydrogen and oxygen to produce electrical power.If the system produces more energy than the train needs at that time,it can store the extra energy in batteries.The train is powered by a hydrogen fuel cell,its only emission being steam and condensed（濃縮的）water.

A single tank of hydrogen can run a Coradia iLint train for about 1,000 kilometers.This is very similar to the distance a diesel-powered train can run on with a single tank.

Hydrogen-powered trains cost more than diesel trains to build.But Alstom officials say the operating costs are much lower.The company confirms another 14 Coradia iLint trains will make their first appearance in Lower Saxony by 2023.

The head of railroad operations in the area,Carmen Schwabl,paid replacing diesel trains with hydrogen-powered trains a compliment.She said the move was a significant milestone in the field of clean transportation.

Hydrogen Alstom uses as fuel is the by-product of an industrial process.In future,Alstom intends to produce hydrogen from wind energy.The area's many wind turbines (渦輪機(jī))will also produce part of the energy to create hydrogen.

Alstom says several other European countries have also expressed interest in embracing a new journey of clean-burning technologies.France has already said it wants its first hydrogen train to be operating by 2024.

Difficult sentence in the text

The new train model,called the Coradia iLint,signifies the beginning of efforts in Germany and other nations to seek an alternative to pollution-producing diesel trains,the number of which in circulation is still high.這種被叫作Coradia iLint 的新列車型號(hào)，標(biāo)志著德國(guó)和其他國(guó)家開始努力尋求替代品，以替代制造污染的柴油列車，目前柴油列車的流通數(shù)量仍然很高。

【點(diǎn)石成金】本句中，called the Coradia iLint 為過去分詞短語(yǔ)作名詞短語(yǔ)The new train model的后置定語(yǔ)；in Germany and other nations和to seek an alternative to pollutionproducing diesel trains 分別為介詞短語(yǔ)和動(dòng)詞不定式作名詞efforts 的后置定語(yǔ)；which引導(dǎo)的是一個(gè)非限制性定語(yǔ)從句，先行詞為pollution-producing diesel trains。
