World's First Zero-Emissions Hydrogen Trains Enter Service

The world's first hydrogen fuel cell train officially entered commercial service in the German state of Lower Saxony on Monday.

The Coradia iLint, developed by French railway manufacturer Alstom, features fuel cells that convert hydrogen and oxygen into electricity, emitting nothing but steam and water. The low-noise train can reach up to 140 kilometers (87 miles) per hour and accommodate up to 300 passengers.


Two such models entered service, replacing some of the noisy, diesel-fueled trains that had been in circulation. Alstom has plans to deliver another 14 Coradia iLints to Lower Saxony by 2021, according to a company press release. The state government has invested €81 million (about $94.7 million) for the technology.

Roughly 120 diesel trains in the existing fleet will reach the end of their lifetime within the next 30 years, meaning the new trains could be a sustainable and practical replacement going forward, a transport official noted.

"The emission-free drive technology of the Coradia iLint provides a climate-friendly alternative to conventional diesel trains, particularly on non-electrified lines," Bernd Althusmann, Lower Saxony's Minister of Economy and Transport, said in the release. "In successfully proving the operability of the fuel cell technology in daily service, we will set the course for rail transport to be largely operated climate-friendly and emission-free in the future."

Passengers will be able to take the new, bright blue trains on a 100-kilometer (62-mile) line running between Cuxhaven, Bremerhaven, Bremervörde and Buxtehude on a fixed timetable.

The two Coradia iLints are fueled at a mobile hydrogen filling station. Hydrogen gets pumped into the train via a 40-foot-high steel container next to the tracks at Bremervörde station. At a full tank, the train can run a full day with up to 1,000 kilometers (621 miles) of autonomy, a range similar to diesel trains. Excess energy is stored with onboard lithium batteries.

"This is a revolution for Alstom and for the future of mobility. The world's first hydrogen fuel cell train is entering passenger service and is ready for serial production," Henri Poupart-Lafarge, chairman and CEO of Alstom, said in the release. "The Coradia iLint heralds a new era in emission-free rail transport. It is an innovation that results from French-German teamwork and exemplifies successful cross-border cooperation."

Alstom said that Britain, the Netherlands, Denmark, Norway, Italy and Canada are also looking into the technology, Agence France-Presse reported. France also wants hydrogen trains to be on its rails by 2022.

"Sure, buying a hydrogen train is somewhat more expensive than a diesel train, but it is cheaper to run," Stefan Schrank, the project's manager at Alstom, told AFP.

Melting Discovered in East Antarctic Region Holding Ice 'Equivalent to Four Greenlands'

Ice sheets in Greenland and West Antarctica have been melting at alarming rates in recent years, but at least the glaciers of East Antarctica were believed to be relatively stable. Until now. National Aeronautics and Space Administration (NASA) scientists have discovered that glaciers covering one-eighth of Antarctica's eastern coast have lost ice in the past 10 years. If the region keeps melting, it has enough ice in its drainage basins to add 28 meters (approximately 92 feet) to global sea level rise, BBC News reported.

The Past 5 Years Were the Arctic's Warmest on Record

The Arctic is still warming at twice the rate of anywhere else on Earth, and the region's air temperatures in the past five years between 2014-2018 have exceeded all previous records since 1900, according to a peer-reviewed report released by the U.S. National Oceanographic and Atmospheric Administration (NOAA) on Tuesday.

The agency's 13th annual Arctic Report Card also concluded that 2018 was second only to 2016 in terms of the region's overall warmth.

3 Key Dangers of Solar Geoengineering and Why Some Critics Urge a Global Ban

By Justin Mikulka

A Harvard research team recently announced plans to perform early tests to shoot sunlight-reflecting particles into the high atmosphere to slow or reverse global warming.

These research efforts, which could take shape as soon as the first half of 2019, fall under the banner of a geoengineering technology known as solar radiation management, which is sometimes called "sun dimming."

Report: Current Climate Policies Will Warm the World by 3.3˚C

This past October, a widely disseminated United Nations report warned that far-reaching and significant climate impacts will already occur at 1.5˚C of warming by 2100.

But in a study released Tuesday, researchers determined that the current climate polices of governments around the world will push Earth towards 3.3˚C of warming. That's more than two times the aspirational 1.5˚C target adopted by nearly 200 nations under the 2015 Paris agreement.

The Lesson From a Burning Paris: We Can’t Tax Our Way Out of the Climate Crisis

By Wenonah Hauter

The images from the streets of Paris over the past weeks are stark and poignant: thousands of angry protesters, largely representing the struggling French working class, resorting to mass civil unrest to express fear and frustration over a proposed new gas tax. For the moment, the protests have been successful. French President Emmanuel Macron backed off the new tax proposal, at least for six months. The popular uprising won, seemingly at the expense of the global fight against climate change and the future wellbeing of our planet.

7 Reasons Why #Mountains Matter

December 11 is International Mountain Day, an annual occasion designated by the United Nations to celebrate Earth's precious mountains.

Mountains aren't just a sight to behold—they cover 22 percent of the planet's land surface and provide habitat for plants, animals and about 1 billion human beings. The vital landforms also supply critical resources such as fresh water, food and even renewable energy.

Don’t Stress About What Kind of Christmas Tree to Buy, but Reuse Artificial Trees and Compost Natural Ones

By Bert Cregg

Environmentally conscious consumers often ask me whether a real Christmas tree or an artificial one is the more sustainable choice. As a horticulture and forestry researcher, I know this question is also a concern for the Christmas tree industry, which is wary of losing market share to artificial trees.
