Over the previous yr, the US has leaned strongly into decarbonization once more, after a detour within the mistaken path for a number of years. I’ve been assessing Republican and Democratic positions on each the issue and answer for years. Up to now yr, nevertheless, the US is once more appearing, and so I’ve been assessing its methods and payments as a substitute of marketing campaign guarantees and, within the case of Republicans, inaction committees.
As I famous in late 2022, the new US hydrogen strategy was established within the mistaken division of presidency, written by the mistaken folks in consequence, with the mistaken focus and as such represents a major failure. By placing hydrogen below the Division of Vitality, it’s handled virtually totally as an power service and efforts to work with the capricious molecule are being focused at that finish of the spectrum. However, in fact, hydrogen is a significant industrial and agricultural decarbonization drawback, and industrial technique is below the Division of Commerce. A great technique would have come from the DOC with enter from the DOE, the DOT, and the USDA. It most likely doesn’t assist that almost all of the DOE’s funds is for nuclear and the whole lot else is an additionally ran within the group.
Against this, the more moderen transportation decarbonization blueprint is usually good. It’s really a cross-department effort — DOT, DOE, EPA, and HUD — with severe evaluation of the necessities of transportation. And it’s not only a refueling blueprint. The HUD involvement results in a robust deal with city density, transit, walkability, bikeability, and the wants of the underside 20% of the socioeconomic ladder. The EPA involvement implies that the air air pollution implications for People’ well being will not be an oh-by-the-way advantage of decarbonization of transportation (though it will be regardless).
However nonetheless.

Have a look at all of that hydrogen. And take a look at all that hydrogen for floor transportation. And particularly for the needs of this text, take a look at hydrogen and sustainable fuels for rail. (As a considerably mitigating observe, the diagram makes hydrogen look extra of a alternative than the main points do, and electrification of rail is taken into account.)
That is exceptional, given the standing of the world’s rail at this time. Let’s take a little bit of a tour of main geographies. And once I say main, I do imply that. China with its 1.four billion residents and a land mass equal to the US. Europe with its 749 million folks in an space barely bigger than the US. And India with its 1.four billion folks residing in a land space a couple of third the scale of the US.
Desk of statistics pertinent to rail assembled from a number of sources by writer
Vastly extra folks in every geography, clearly, however equal geographical reaches and geographical variety. Railway strains that should go simply as far, and thru simply as difficult terrain. Clearly at a number of ranges of growth from the mature economies of Europe to the nonetheless quickly creating China to the now quickly creating India.
All economies which have large volumes of products and ranging numbers of passengers touring by rail. I used to be to find that the US has extra miles of rail than any of those areas and near as a lot as China and India mixed. The US is an outlier when it comes to passenger rail miles, which is unsurprising in a rustic that loves vehicles and suburbs. No judgment, however rail is clearly nonetheless a massively vital freight cargo mode, and transshipment of containers revitalized the business.
So let’s take a look at that final row. One in all this stuff will not be like the opposite, considered one of this stuff will not be the identical. Actually, the share of electrified rail will not be even 1%, however the one supply I had indicated that it was below 1%, so I rounded up.
In the meantime, India is at 83% rail electrification, and is forward of schedule to attain virtually 100% grid-tied electrification. I noticed that when a headline crossed my display in regards to the nation ordering 35 hydrogen locomotives. That struck me as fascinating, so I checked a denominator. The nation has virtually 13,000 locomotives, so 35 is about 0.25% of its fleet. And the hydrogen locomotives are solely getting used on ‘heritage’ narrow-gauge railways, in different phrases tiny segments maintained for tourism causes that occur to undergo actually inhospitable however lovely areas the place preserving the views really has financial advantage. Personally, I’d have chosen biodiesel for that as a substitute, however it’s such a tiny fraction of the house that I don’t actually care. And the percentages that the hydrogen fleet will develop is low.
China is fascinating as properly. It’s heading towards 100% too. It’s constructed 40,000 km (30,000 miles) of grid-tied electrified high-speed freight and passenger rail since 2007, with extensions to attach main cities within the neighboring nations of Laos and Vietnam in operation and below building respectively. And it’s constructing electrified larger pace rail in a number of nations below its belt and highway initiative. It’s really doable that Ethiopia’s Chinese electrified rail route at 760 kilometers is by itself greater than all electrified tracks within the US at this time.
After which there’s Europe, lagging electrification with solely 60% thus far. However information from one of many main economies within the continent, Germany’s state of Baden-Württemberg, one of many bigger and richer states, is indicative of the path. The state did a examine, discovered hydrogen could be 3 times costlier than grid-tied electrical and virtually precisely the identical outcomes for grid-tied battery hybrid electrical, and has acknowledged unequivocally that it received’t hassle with hydrogen sooner or later. Sorry, Alstom, whereas you will have convinced Quebec to run considered one of your hydrogen locomotives alongside a stretch of observe for a number of months, you aren’t going to be promoting that dead-end tech in Europe.
So let’s see. China and Europe run massively extra freight throughout electrified rail than the US. The three areas have 1.eight occasions as many miles of rail as America, and climbing as China continues to construct quickly. All three are heading towards 100% electrified rail.
However the US can’t electrify its rail? What’s up with that? Is it as a result of American locomotives can’t use electrical energy? No, all locomotives working in North America are diesel-electric hybrids. The motors that flip the wheels are electrical, and when they’re used for braking they generate electrical energy. The diesel engine is a generator, not a torque-traction engine as it’s on large vans. Do main suppliers of American locomotives not make catenary-tied locomotives? Nope, GE, Alstom, and each producer has that of their equipment bag as a result of the big majority of the world makes use of it.
Is it as a result of the US is particular geographically? Nope, Europe and China are greater than America and have equally difficult terrain, and it’s not like India is the scale of Luxembourg or Rhode Island.
Does the US have particular climate situations? Nope, each Europe and China have a lot of rail working in ice and snow within the north, and China and India each have trains working in hotter and muggier temperatures than the US experiences.
You would possibly be capable to make a case for the restricted passenger utilization of rail being one thing to contemplate, because the stench of freight engine diesel is one thing which may encourage rail passengers to help electrification, however that’s a tough promote.
Is it as a result of rail electrification is vastly costlier? Actually? India can hit 83% on its approach to 100% and the US can’t afford it?
Is it as a result of it’s not possible to retrofit the 23,400 or so US locomotives for overhead catenary connections or add vehicles with batteries to them? No, overhead catenary connections are such bathroom commonplace connections that locomotives have been bought with them as an possibility, one which will be added later, for many years. And commonplace delivery containers with batteries in them are already on US rails, they’re simply going to grid and behind-the-meter storage websites, pre-built by firms like Tesla and Wärtsilä.
Is it as a result of hydrogen or artificial fuels made out of hydrogen could be cheaper than electrical energy? No, hydrogen is at very minimal 3 times the price of electrical energy as a result of it takes three items of electrical energy to make one unit of hydrogen with equal power. However in fact with all of the adders and inefficiencies, it’s extra like 5-7 occasions as costly. And due to that 5-7 issue, hydrogen and artificial fuels at all times multiply any carbon debt of every MWh of electrical energy used to make them. Biofuels are cheaper than hydrogen or artificial fuels and at all times will probably be, to not point out decrease carbon for the foreseeable future, however they will even be costlier than electrical energy, and losing them on floor transportation stays mindless.
No, the US has one different method it’s distinctive in comparison with these areas. The entire rails are owned by personal firms, not the federal government, they usually refuse to impress them. The actual answer could be for the US to both nationalize the rails — not going to occur, one assumes, though hydroelectric dams are nationally owned and rail nationalization has occurred a number of occasions on the earth — or to rationally incent the rail homeowners to impress. Every thing else is a waste of time, cash, and carbon funds. Dealing intelligently with rail could be driving quickly to electrification and just about ignoring the whole lot else.
All of which means in 20 years, the one main marketplace for diesel locomotives would be the US, whereas the remainder of the world eliminates the diesel generator from their trains. And it’s extremely doubtless that the US will find yourself losing biodiesel within the locomotives as a substitute of preserving the stuff for marine delivery, the place you’ll be able to’t connect the ships to overhead strains. As for hydrogen locomotives, they’ll be an excellent tinier market.
And you understand what tiny markets means? Increased costs. Sure, US rail insurance policies imply that it’s going to power a lot larger capital and operational prices into its freight distribution system than the opposite main economies of the world will expertise. As China’s buying energy parity is already giving it round a 40% cost benefit on everything in its domestic economy, that’s not a rational alternative.
Rail within the US is a case the place an enormous transportation phase is deeply out of step with the remainder of the world, and that’s not as a result of the explanations stand as much as the slightest scrutiny. The US and the transportation blueprint are merely mistaken about rail, and People pays the worth if this isn’t corrected.
