The US locomotive maker Wabtec has been spreading the electrical practice message far past its residence base of Pittsburgh, Pennsylvania. That now consists of Brazil, the place the main mining agency Vale has simply ordered up three of Wabtec’s FLXdrive zero emission locomotives to ply a 550-mile railroad, pulling a great deal of ore from the world’s greatest iron mine. The 2 corporations additionally plan on taking a joint dive into the ammonia gas pond, as well. Wait, what?
Vale Catches Electrical Prepare Fever, Partly
The three electrical locomotives will assist decarbonize Vale’s iron ore practice on the 550-mile Carajás Railroad (EFC or Estrada de Ferro Carajás in Portuguese). The railway is a part of the Larger Carajás Undertaking managed by Vale, the centerpiece of which is the largest open pit mine of iron ore on Earth, situated within the mountainous northern rainforest state of Pará. The practice stops at numerous metal crops alongside its option to the Atlantic port of Ponta da Madeira, in São Luís (Nationwide Geographic has extra background on the Carajás Undertaking).
The scale of the ore practice matches the chore in hand. The journey usually requires three diesel locomotives, and typically 4, to drag 330 railcars carrying a complete of 45,000 tons, making it the longest iron ore practice on this planet.
Two of the locomotives are “dynamic helpers” which can be solely wanted for a part of the route, an uphill climb of about 87 miles in Açailândia, within the state of Maranhão.
The plan is to transform the Vale practice right into a hybrid. The primary of its sort in Brazil, the brand new practice will ditch the 2 dynamic helpers and exchange them with three FLXdrive electrical locomotives, leaving only one diesel locomotive to hold the torch for fossil vitality.
With an help from regenerative braking, Wabtec and Vale count on the three electrical locomotives to chop 25 million liters of diesel from Vale’s carbon footprint, representing the emissions of about 14,000 passenger vehicles per 12 months.
Wabtec Shares The Zero Emission Electrical Prepare Love, With Ammonia
The Carajás Railroad represents a major step up in scale from the route plied by Wabtec’s first electrical practice within the US, a 139-mile route between Ohio and Pennsylvania. It was additionally the primary ever all-electric locomotive for use for freight hauling within the US, though it didn’t fly solo. CleanTechnica made this remark simply earlier than the brand new FLXdrive hit the rails:
“Wabtec’s new battery-electric locomotive…will make its first runs on a 139-mile route from the suburbs of Pittsburgh, Pennsylvania to the city of Conneaut, Ohio, chaperoned by the most recent iteration of the corporate’s gas environment friendly diesel locomotives. The diesel-electric combo might disappoint electrification followers, however Wabtec nonetheless expects an total emissions reduce of 30%, which is not any small potatoes.”
The Carajás Railroad enterprise follows the identical sample of mixing diesel and electrical locomotives in a single practice, however this time round Wabtec is setting its sights on zeroing out emissions totally. The plan is to transform the remaining diesel engine to run on ammonia. That will take a while. Wabtec and Vale have agreed to collaborate on a joint, two-year examine of ammonia gas, starting with in-lab assessments.
Efficiency, emission reductions, and feasibility are all in play, which implies that the ammonia gas thought won’t occur in spite of everything. Nonetheless, probabilities for fulfillment are rising as the marketplace for ammonia gas catches on. “Among the many benefits of ammonia is the truth that it permits the locomotive an extended vary than different carbon-free fuels. As well as, ammonia has a high-octane score and a longtime large-scale distribution infrastructure,” Wabtec notes.
Make That Inexperienced Ammonia
Ammonia is a hydrogen-dense molecule, as indicated by the chemical method NH3, which means one nitrogen atom and three hydrogen atoms. It might play a pivotal position within the inexperienced hydrogen economic system of the long run, partly by serving as a storage and transportation medium for hydrogen.
“The US Division of Power is amongst these eyeing ammonia for enhancing the cost-efficiency of hydrogen storage and transportation… The problem is crack the hydrogen off when it’s wanted, economically and effectively,” CleanTechnica noticed in 2021.
Final March, the Kleinman Middle for Power Coverage assessed the state of affairs and supplied help for the concept that inexperienced hydrogen sourced from water will finally dominate the market, resulting in the creation of a inexperienced ammonia trade. Nonetheless, they indicated that utilizing ammonia as a hydrogen service could also be overplayed. Nonetheless, that leaves the door open for utilizing inexperienced ammonia instantly as a substitute for diesel and different heavy fuels.
The Kleinman Middle additionally cautioned that ammonia shouldn’t be a pollution-free gas, with nitrogen oxide being the first wrongdoer. A paper revealed by the science group Frontiers in 2021 up backs up that evaluation. The authors advocate for extra analysis to curb NOx emissions earlier than ammonia goes mainstream as a gas or gas combination.
“NH3 is a beautiful various gas candidate to scale back the consumption of fossil gas and the emission of CO2, soot, and hydrocarbon pollution, attributable to its comparable combustion properties, productivities from renewable sources, and storage and transportation by present industrial infrastructure,” the authors be aware. “Nonetheless, the combustion properties of NH3 are fairly completely different from typical hydrocarbon fuels, which spotlight the precise difficulties throughout the utility of NH3.”
Nonetheless, the maritime trade has already put itself forth as an early adopter of inexperienced ammonia gas, as famous by the Worldwide Power Company in a latest report. The worldwide transport large Yara, for instance, has been experimenting with inexperienced ammonia gas in addition to battery-electric cargo vessels.
The railroad trade might not be far behind. Wabtec already has some firm within the search to enrich its electrical practice enterprise with various fuels. Final 12 months, the Ammonia Power Affiliation famous that Fortescue Future Industries is testing two ammonia locomotives on four-stroke diesel engines, following a profitable take a look at of blended gas on two-stroke engines.
Decarbonization Past The Mines
The Vale collaboration is simply the most recent in a collection of worldwide strikes that Wabtec has made within the mining sector, with Rio Tinto and BHP additionally leaping on the FLXdrive electrical practice bandwagon.
The corporate has additionally adopted a broader strategy to railway decarbonization as a associate in Europe’s Rail Joint Enterprise, which launched in 2021 on a mission to ship “a high-capacity, versatile, multimodal, sustainable, dependable and built-in EU railway community for European passengers and cargo.” In help of the mission, earlier this 12 months Wabtec signed a three-year settlement with the Polytechnic College of Turin, with an eye fixed on securing the following era of railway innovators and steering the trade in the direction of sustainable options.
When can we get one in every of these for the US? Don’t maintain your breath. Indicators of a coordinated strategy to railroad decarbonization have been rising, however slowly. Again in 2021, Wabtec joined with Carnegie Mellon College in Pittsburgh and the Genesee & Wyoming railroad to suggest the creation of a brand new Freight Rail Innovation Institute beneath the US Division of Transportation. A invoice to that impact was launched within the Home of Representatives in 2021 and has languished there ever since.

I do not like paywalls. You do not like paywalls. Who likes paywalls? Right here at CleanTechnica, we applied a restricted paywall for some time, nevertheless it all the time felt improper — and it was all the time powerful to resolve what we must always put behind there. In concept, your most unique and finest content material goes behind a paywall. However then fewer folks learn it! We simply don’t love paywalls, and so we have determined to ditch ours.
