The California Division of Transportation, in any other case often known as Caltrans, plans to transform its full fleet of intercity locomotives to zero emission, or ZE, expertise by 2035. To attain that aim, trains operated by native transportation businesses will likely be powered by hydrogen, which is taken into account a sustainable, much less polluting, and doubtlessly price efficient various to fossil fuels and different sources of vitality. Hydrogen energy will put California’s passenger prepare fleet on the quickest observe towards a zero emission future, the company says.

The Guardian experiences {that a} new prepare powered by a hydrogen gas cell will start working between the cities of Redlands and San Bernardino, close to Los Angeles, early subsequent 12 months. Take a look at runs are being carried out immediately. From the surface, it seems to be like some other commuter prepare, however inside, it’s not like something the area — or the nation — has ever seen earlier than. The $20 million Zero Emission A number of Unit prepare, recognized fondly as Zemu, makes use of a hydrogen gas cell and battery system to energy the electrical traction motors and run the onboard electrical programs. The one byproduct of the gas cell is water vapor, which is a welcome change in an space that suffers from a number of the worst air high quality charges within the nation.

1st Hydrogen-Powered Practice In The US

The brand new expertise will make Zemu the primary hydrogen-powered, zero-emissions passenger prepare in North America to satisfy Federal Railroad Administration (FRA) necessities when it goes into service early subsequent 12 months. The observe between the 2 cities is called the Arrow Hall and it is just 9 miles lengthy. It is among the area’s shortest rail hyperlinks and carries about 416 passengers day by day throughout the week and greater than 6,430 riders on weekends. Its operators hope that Zemu will pave the best way for zero-emissions trains to run on lots of of miles of observe in southern California and throughout the nation within the close to future.

That would mark the beginning of a clear vitality rail motion within the US, which has historically lagged behind locations like Europe in terms of each prepare ridership and innovation. It’s additionally a win for California, which has struggled to get formidable rail initiatives like its high-speed rail line between San Francisco and Los Angeles accomplished.

“What we have now achieved with Zemu is transformational,” mentioned Ray Marquez, the president of the San Bernardino county transit authority in a press release. “The event of the hydrogen powered prepare has solidified SBCTA’s place as an innovator in clear passenger rail right here within the Inland Empire, all through the state and the nation.” The debut of this expertise in North America comes because the better Los Angeles area prepares for the 2028 Olympics, which the mayor of the town has mentioned will likely be a “no-car” video games. As well as, Zemu will assist California meet its aim of being carbon impartial by 2045.

For many years, San Bernardino has suffered from poor air high quality introduced on by a excessive focus of freeways, rail yards, industrial services, and freight terminals. Motivated by the poor air high quality and a want to scale back the stress on the county’s roads, which are sometimes crowded with vans transporting items from the ports of Los Angeles and Lengthy Seashore, SBCTA officers set out a decade in the past to search out clear alternate options to their current diesel trains. They landed on the hydrogen-powered Zemu, and in 2019 contracted with Swiss rail producer Stadler, Inc to construct them.

Anatomy Of A Hydrogen Gasoline Cell

Hydrogen gas cells mix hydrogen and oxygen molecules to generate electrical energy and produce water vapor as a byproduct. In observe, the gas cell features as an onboard generator that expenses the batteries that flip the wheels of the prepare. CleanTechnica readers, who’re all nicely above common, will spot the detrimental facet of this expertise immediately. Nearly all hydrogen within the US is constructed from methane fuel in a course of that the majority undoubtedly does create carbon dioxide, so actually what Zumi is doing is making the most of a zero emissions technique that leaves its carbon footprint some place else. In fact, sometime inexperienced hydrogen produced from renewable vitality will resolve this subject. Till then, we’re left to fake these trains are a non-polluting technique of transportation.

Assembly The Security Problem

For passengers, the hydrogen gas cell expertise means a quieter trip. “All you’re going to listen to is a pair HVAC blowers and cooling followers,” mentioned Kaden Killpack, a business mission supervisor at Stadler US who oversees the SBCTA and Caltrans initiatives. Riders may additionally discover a smoother journey because of the prepare’s light-weight development. Nonetheless, the light-weight, aluminum physique design posed new challenges for Stadler, which wanted to show its trains may function safely on California’s current rail infrastructure. Lighter trains are extra vitality environment friendly, however with a view to function on the identical tracks as heavy freight, Stadler wanted to display that its aluminum trains may go the Federal Railroad Administration’s requirements for entrance finish collisions.

Creating a light-weight body that handed FRA requirements is a promising accomplishment as a result of it offers a zero emission various to the costly overhead electrification that’s widespread in Europe however is prohibited on freight strains within the US. “As soon as you are taking that car and also you add hydrogen to it, you make it potential to have zero emission expertise on the identical corridors the place Union Pacific and NSF run,” Killpack mentioned. “That’s what’s actually loopy and funky about this.”

One Small Step For San Bernardino

Inserting the Zemu on the Arrow Hall is admittedly a small first step, Watkins says: “It’s one prepare, so it doesn’t transfer the needle dramatically.” However, he says, “it introduces the expertise as a proof of idea” that might run on greater than 500 miles of southern California’s regional rail system and past. After seeing the early success of the Zemu mission final 12 months, Caltrans commissioned Stadler to construct longer variations of its hydrogen-powered trains that can run between Merced and Sacramento within the Central Valley on a brand new rail line.

To ensure that these small however promising steps to be economically sustainable in the long term, giant investments in hydrogen infrastructure will required. “You’ve bought to be promoting a minimum of lots of [of trains] to begin to get some scale economies and produce these prices down,” Lewis Fulton, the director of the Vitality Futures Program on the UC Davis’s Institute for Transportation Research. Whatever the challenges, California officers are pushing hydrogen gas cell transportation ahead.

A mixture of state, federal, and personal funding, California’s Alliance for Renewable Clear Hydrogen Vitality Programs will distribute some $12.6 billion to get 1000’s of hydrogen-powered buses, vans, and vehicles onto the street and to construct hydrogen manufacturing and distribution hubs to run these rising fleets. Fulton mentioned the Zemu initiatives are a results of these investments. “What we’re seeing in California now’s a way that hydrogen is coming and infrastructure is coming, and so why not faucet into that?”

The Takeaway

My colleague Michael Barnard shouldn’t be a believer in hydrogen gas cells for vehicles, vans, and trains. Though, he is perhaps persuaded to alter his thoughts if extra inexperienced hydrogen was obtainable and if it didn’t suck up each little bit of renewable vitality obtainable within the course of of creating it. Caltrans could also be over the moon about trains and vans powered by hydrogen, however till it’s produced commercially with out creating its personal cloud of air pollution, its promise will stay largely illusory.
