Germany comes clean with zero-emission passenger train service

alstom hydrogen powered zero emission train

Alstom is ready to break new ground with its newly introduced Coradia iLint passenger train, reports the Independent. Unveiled during August’s Berlin InnoTrans trade show, the iLint is the world’s first zero-emission train that is powered by hydrogen. If the last round of testing goes as planned, the “hydrail” train will go into operation as soon as next year.

What sets the Coradia iLint apart is its unique method of power generation. Instead of relying on fossil fuels like diesel, the iLint is powered by lithium ion batteries that are supplied a charge by an onboard hydrogen fuel cell. When compared to diesel engines, the hydrogen engine of the iLint is environmentally friendly, producing only steam and condensed water as byproducts. And if that doesn’t make it the greenest train on the planet, this other advantage will.

According to Die Welt, Alstom also is in the business of recycling waste hydrogen in its fuel cells. The hydrogen is supplied by chemical companies that typically would burn the hydrogen instead of putting it to good use as a fuel source. “Alstom is proud to launch a breakthrough innovation in the field of clean transportation,” said Alstom CEO Henri Poupart-Lafarge when the train was first unveiled.

In a country where more than 4,000 diesel trains are in operation, the hydrogen engine is an operator’s dream. The hydrail can travel at speeds up to 87 mph and can cover almost 500 miles a day. It also is incredibly quiet, with the only noise coming from the wheels on the rails, and air resistance as the train rushes down the track.

Alstrom may be the first firm to use hydrogen fuel in a train, but it is not the first company to take advantage of this clean power source. NASA has been using hydrogen in rocket boosters since the 1970s, sending its rockets skyward with a burst of steam. Car manufacturers also have dabbled with hydrogen, but have not yet released a high-volume hydrogen-powered production model to the public.

Alstom is in the final stages of preparing its hydrail for public release. The trains are undergoing the last stages of testing and regulatory approval process this fall. If this process is a success, Alstom is expected to offer public hydrail service by December 2017. Interest in the hydrogen-powered train is mounting, with northern Germany’s Lower Saxony placing an order for 14 of the trains when they become available next year.

There's a scene in Mission Impossible 3 that you might recall. In it, our hero Ethan Hunt (Tom Cruise) tackles the movie's villain, holds him at gunpoint, and forces him to read a bizarre series of sentences aloud.

"The pleasure of Busby's company is what I most enjoy," he reluctantly reads. "He put a tack on Miss Yancy's chair, and she called him a horrible boy. At the end of the month, he was flinging two kittens across the width of the room ..."

Digital Trends’ Top Tech of CES 2023 Awards
Best of CES 2023 Awards Our Top Tech from the Show Feature

Let there be no doubt: CES isn’t just alive in 2023; it’s thriving. Take one glance at the taxi gridlock outside the Las Vegas Convention Center and it’s evident that two quiet COVID years didn’t kill the world’s desire for an overcrowded in-person tech extravaganza -- they just built up a ravenous demand.

From VR to AI, eVTOLs and QD-OLED, the acronyms were flying and fresh technologies populated every corner of the show floor, and even the parking lot. So naturally, we poked, prodded, and tried on everything we could. They weren’t all revolutionary. But they didn’t have to be. We’ve watched enough waves of “game-changing” technologies that never quite arrive to know that sometimes it’s the little tweaks that really count.

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.
[CES 2023] Relumino Mode: Innovation for every need | Samsung
Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.
