California To Start Hydrogen-Powered Passenger Practice Service In San Bernardino

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, know-how by 2035. To attain that objective, trains operated by native transportation businesses shall be powered by hydrogen, which is taken into account a sustainable, much less polluting, and probably value efficient various to fossil fuels and different sources of power. Hydrogen energy will put California’s passenger practice fleet on the quickest monitor towards a zero emission future, the company says.

The Guardian experiences {that a} new practice powered by a hydrogen gasoline cell will start working between the cities of Redlands and San Bernardino, close to Los Angeles, early subsequent yr. Check runs are being carried out at present. From the skin, it seems like another commuter practice, however inside, it’s in contrast to something the area — or the nation — has ever seen earlier than. The $20 million Zero Emission A number of Unit practice, identified fondly as Zemu, makes use of a hydrogen gasoline cell and battery system to energy the electrical traction motors and run the onboard electrical techniques. The one byproduct of the gasoline cell is water vapor, which is a welcome change in an space that suffers from among the worst air high quality charges within the nation.

1st Hydrogen-Powered Practice In The US

The brand new know-how will make Zemu the primary hydrogen-powered, zero-emissions passenger practice in North America to satisfy Federal Railroad Administration (FRA) necessities when it goes into service early subsequent yr. The monitor between the 2 cities is named the Arrow Hall and it’s only 9 miles lengthy. It is likely one of the area’s shortest rail hyperlinks and carries about 416 passengers each 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 a whole bunch of miles of monitor in southern California and throughout the nation within the close to future.

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

“What we’ve got finished with Zemu is transformational,” stated Ray Marquez, the president of the San Bernardino county transit authority in a press release. “The event of the hydrogen powered practice 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 know-how in North America comes because the better Los Angeles area prepares for the 2028 Olympics, which the mayor of the town has stated shall be a “no-car” video games. As well as, Zemu will assist California meet its objective 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 amenities, and freight terminals. Motivated by the poor air high quality and a need to cut back the stress on the county’s roads, which are sometimes crowded with vehicles 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 Gas Cell

Hydrogen gasoline cells mix hydrogen and oxygen molecules to generate electrical energy and produce water vapor as a byproduct. In apply, the gasoline cell features as an onboard generator that costs the batteries that flip the wheels of the practice. CleanTechnica readers, who’re all nicely above common, will spot the destructive facet of this know-how straight away. Nearly all hydrogen within the US is created from methane fuel in a course of that the majority undoubtedly does create carbon dioxide, so actually what Zumi is doing is profiting from a zero emissions technique that leaves its carbon footprint elsewhere. In fact, sometime inexperienced hydrogen produced from renewable power will clear up this situation. Till then, we’re left to faux these trains are a non-polluting technique of transportation.

Assembly The Security Problem

For passengers, the hydrogen gasoline cell know-how means a quieter experience. “All you’re going to listen to is a pair HVAC blowers and cooling followers,” stated Kaden Killpack, a industrial undertaking supervisor at Stadler US who oversees the SBCTA and Caltrans tasks. Riders may additionally discover a smoother journey as a result of practice’s light-weight building. Nonetheless, the light-weight, aluminum physique design posed new challenges for Stadler, which wanted to show its trains might function safely on California’s current rail infrastructure. Lighter trains are extra power environment friendly, however with the intention to function on the identical tracks as heavy freight, Stadler wanted to reveal that its aluminum trains might 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 traces within the US. “As soon as you’re taking that car and also you add hydrogen to it, you make it potential to have zero emission know-how on the identical corridors the place Union Pacific and NSF run,” Killpack stated. “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 practice, so it doesn’t transfer the needle dramatically.” However, he says, “it introduces the know-how as a proof of idea” that would run on greater than 500 miles of southern California’s regional rail system and past. After seeing the early success of the Zemu undertaking final yr, 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, massive investments in hydrogen infrastructure will required. “You’ve bought to be promoting at the least a whole bunch [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 gasoline cell transportation ahead.

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

The Takeaway

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