Hydrogen-powered locomotives could eventually help reduce railway emissions to almost zero

European passenger trains are starting to transition to hydrogen power. But in North America, it’s a Canadian freight railway leading the way. Here’s the state of the hydrogen locomotive opportunity, answers to some key questions – and what comes next.

Hydrogen is the most abundant element in the universe and the third most common element on Earth. It also might be the key to unlocking the decarbonization of a sector that gets relatively little climate-adaptation press coverage: rail transportation.

Now there’s a reason that railways (or railroads as our American neighbours to the south like to call them) get so little press when it comes to the climate crisis. As legacy industries go, rail is already relatively efficient from an emissions perspective.

As the Railway Association of Canada notes:

“Each year, Canada’s railways move tens of millions of passengers and 70 per cent of all intercity freight, while producing just 1.1 per cent of Canada’s greenhouse gas (GHG) emissions. And only 3.8 per cent of the country’s transportation sector GHG emissions.”

Still, in late 2020, CPKC – formerly known as Canadian Pacific Railway or CPR – became one of the first of the class-1 North American railways to begin development of a line-haul hydrogen-powered locomotive pilot. (Class-1 railways are the largest in North America, each with annual revenues over $250M USD per year. Line-haul refers to the movement of trains between cities/towns rather than lighter in-yard switching work).

CPKC’s 2020 embrace of hydrogen ran nearly parallel to the release of the Government of Canada’s Hydrogen Strategy, which, in a section on transportation, noted:

“High profile, medium- and heavy-duty fuel cell electric vehicle pilot projects will help raise awareness and best practices for pilot deployments of zero-emissions vehicles for goods and people movement in all sectors: on-road, rail, marine, and aviation.”

Since 2020, CPKC has expanded its hydrogen locomotive program with additional locomotives and hydrogen production/fuelling facilities. In 2022, the railway first used a hydrogen-powered locomotive to make a revenue run, which brought the technology one step closer to replacing a diesel engine in the company’s locomotive fleet.

So the technology is gaining traction here in Canada. But you may have some questions, so we’ve got answers.

How do hydrogen locomotives work?

This is an obvious question.

For our answer let’s go to TWI, a globally-known independent research and technology firm:

“Current technology focuses on the use of hydrogen fuel cells, which generate electricity using a chemical reaction between two electrodes… Hydrogen acts as the fuel in the cell with the addition of oxygen, generating electrical energy. 

The technique used to obtain the hydrogen has an impact on how environmentally friendly the hydrogen is. Steam reforming, for example, uses harmful fossil fuels, while electrolysis using renewable energy electricity or excess power from the Grid creates no carbon emissions.”

Still a bit too complicated? It’s basically this: when combined, hydrogen, and oxygen react to produce electricity, which powers the locomotive. 

But you need to get the hydrogen to begin with. You can do that by using fossil fuels or renewable energy. Obviously, by using renewable energy you avoid creating emissions in your production of hydrogen, making the whole system cleaner and greener. It’s also why this kind of hydrogen is commonly referred to as ‘green hydrogen.’

What would be the benefits of railways switching to hydrogen-powered locomotives?

There are three key benefits to note.

The first is that a hydrogen-powered locomotive fleet would not require modifying the track infrastructure already in place to take advantage of traditional approaches to electrification. For railways with thousands of miles of track, that’s a huge benefit. In fact, hydrogen is, as of now, the only feasible choice.

Of course, there would still be the need to build out hydrogen filling stations along main routes, which is nothing CPKC or any other class-1 now piloting hydrogen locomotives has done to date. But those costs are nothing compared to full electrification of the roughly 170,000 miles of freight rail in North America.

A second benefit is that hydrogen locomotives run more quietly than their diesel counterparts. Smaller perhaps as benefits go but it’s still of value, especially because rail lines often run close to where people live and work.

It’s the third benefit that’s the massive one. Hydrogen-powered locomotives emit only water — a game changer for rail transportation. Regardless of how the hydrogen is obtained, to run a train from Vancouver to Montreal without emitting CO2? 

That’s an extraordinary opportunity for the industry and the country.

How long will it take for railways to replace diesel locomotives with hydrogen locomotives?

This is the (multi) billion-dollar question. And while this is a highly promising technology, it’s not clear that hydrogen will be the answer to the rail industry’s decarbonization aspirations. One reason is that hydrogen’s lack of energy density makes it more challenging to deploy it at scale in locomotives, because it must be stored as a liquid at temperatures of 250°C or less or at pressures of 5,000-1000 psi (which is hundreds of times greater than Earth’s atmospheric pressure). Neither is an easy or cost-effective task.

Of course that’s all based on current technology. Which will improve over time.

And of course this isn’t the first time in history the rail industry has looked at shifting its locomotive power sources. 

The railway industry has been around approximately 200 years, with the diesel locomotive being the industry standard since it replaced the steam engine in the early 1940s.

Diesel locomotives actually originally appeared in the 1920s. They were used for lighter duty railcar switching and passenger duty before they became robust enough to haul freight. That’s a twenty-ish year gap between launch and broad adoption. It’s worth noting because it may tell us something about the length of time necessary for an innovative new technology to become an industry standard, and drive down overall sector emissions.

There also remain significant questions about hydrogen locomotive performance, particularly for railways that operate in adverse weather conditions. As the old rail-industry adage goes, ‘railroading is an outdoor sport.’

As CPKC CEO Keith Creel said at the 2022 RailTrends conference (via Trains.com):

“The next step is scalability,” Creel says, through partnering with a customer that can build enough road locomotives to prove the technology on the rugged CP main line in the Canadian Rockies west of Calgary.

“It’s the perfect test bed. If you can operate there — heavy haul, cold temperatures, the most challenging operational conditions I’ve ever experienced in my career … it will work anywhere,” Creel says.

What’s happening with hydrogen-powered trains in Europe? Don’t Europeans love trains?

They sure do. 

So, it’s no surprise that in parts of Europe some passenger trains are already being converted to hydrogen-powered locomotives. The sheer mass of heavy freight rail trains vs. lighter passenger rail trains makes it almost inevitable that hydrogen locomotives will consistently move people before they consistently move goods.

Alstom, a French company that makes rolling stock (meaning locomotives or other types of railcars/tank cars/other cars that make up trains), recently announced that it has helped create the first fully hydrogen-fueled passenger train route in Germany. The company also has contracts for hydrogen trains (or ‘hydrail’) in both Italy and France. So the technology is rolling out on the continent.

And the US is close behind. American rolling stock manufacturer Stadler Rail will be producing a hydrogen-powered passenger train that will begin operating  in San Bernardino, CA in 2024.

So, what’s happening now? And what’s happening next?

One way to predict the transition to renewable energy-powered locomotives is to look at how we’re transitioning to renewable energy-powered cars. Many consumers aren’t jumping directly from internal combustion engines to electric vehicles, they’re bridging the gap with a hybrid car.

That’s happening in the rail sector too.

In February of this year, the US Department of Energy announced it was partnering with rail technology company Wabtec to “develop a hybrid locomotive engine that can run on both hydrogen and diesel.” Freightways reports that:

“The project… will run for four years and consist of two phases. Phase one will be development of the hybrid engine and phase two will create new hardware that would serve as the next generation of locomotive engines to be gradually introduced into the marketplace.”

Meanwhile, in Quebec, another Alstom hydrogen passenger train will make its inaugural run this summer as a first step into the North American market.

In fact, there are almost too many instances of hydrogen train pilots and deployments around the world to keep track of them all.

The technology is driving investment, and excitement, even amongst the most senior, seasoned executives.

Keith Creel again, in November 2022:

“To see [a hydrogen locomotive] two weeks ago, running down the main line at main line speed pulling a load behind it, I mean it made the hairs on my arm stand up because I would have told you two years ago it’s a pipe dream … Well, it’s not a pipe dream. It’s a reality. Still a lot of work left to do, but it’s super, super exciting.”

How businesses can protect themselves from the rising threat of deepfakes

Dive into the world of deepfakes and explore the risks, strategies and insights to fortify your organization’s defences

Published

on

In Billy Joel’s latest video for the just-released song Turn the Lights Back On, it features him in several deepfakes, singing the tune as himself, but decades younger. The technology has advanced to the extent that it’s difficult to distinguish between that of a fake 30-year-old Joel, and the real 75-year-old today.

This is where tech is being used for good. But when it’s used with bad intent, it can spell disaster. In mid-February, a report showed a clerk at a Hong Kong multinational who was hoodwinked by a deepfake impersonating senior executives in a video, resulting in a $35 million theft.

Deepfake technology, a form of artificial intelligence (AI), is capable of creating highly realistic fake videos, images, or audio recordings. In just a few years, these digital manipulations have become so sophisticated that they can convincingly depict people saying or doing things that they never actually did. In little time, the tech will become readily available to the layperson, who’ll require few programming skills.

Legislators are taking note

In the US, the Federal Trade Commission proposed a ban on those who impersonate others using deepfakes — the greatest concern being how it can be used to fool consumers. The Feb. 16 ban further noted that an increasing number of complaints have been filed from “impersonation-based fraud.”

A Financial Post article outlined that Ontario’s information and privacy commissioner, Patricia Kosseim, says she feels “a sense of urgency” to act on artificial intelligence as the technology improves. “Malicious actors have found ways to synthetically mimic executive’s voices down to their exact tone and accent, duping employees into thinking their boss is asking them to transfer funds to a perpetrator’s account,” the report said. Ontario’s Trustworthy Artificial Intelligence Framework, for which she consults, aims to set guides on the public sector use of AI.

In a recent Microsoft blog, the company stated their plan is to work with the tech industry and government to foster a safer digital ecosystem and tackle the challenges posed by AI abuse collectively. The company also said it’s already taking preventative steps, such as “ongoing red team analysis, preemptive classifiers, the blocking of abusive prompts, automated testing, and rapid bans of users who abuse the system” as well as using watermarks and metadata.

That prevention will also include enhancing public understanding of the risks associated with deepfakes and how to distinguish between legitimate and manipulated content.

Cybercriminals are also using deepfakes to apply for remote jobs. The scam starts by posting fake job listings to collect information from the candidates, then uses deepfake video technology during remote interviews to steal data or unleash ransomware. More than 16,000 people reported that they were victims of this scam to the FBI in 2020. In the US, this kind of fraud has resulted in a loss of more than $3 billion USD. Where possible, they recommend job interviews should be in person to avoid these threats.

Catching fakes in the workplace

There are detector programs, but they’re not flawless. 

When engineers at the Canadian company Dessa first tested a deepfake detector that was built using Google’s synthetic videos, they found it failed more than 40% of the time. The Seattle Times noted that the problem in question was eventually fixed, and it comes down to the fact that “a detector is only as good as the data used to train it.” But, because the tech is advancing so rapidly, detection will require constant reinvention.

There are other detection services, often tracing blood flow in the face, or errant eye movements, but these might lose steam once the hackers figure out what sends up red flags.

“As deepfake technology becomes more widespread and accessible, it will become increasingly difficult to trust the authenticity of digital content,” noted Javed Khan, owner of Ontario-based marketing firm EMpression. He said a focus of the business is to monitor upcoming trends in tech and share the ideas in a simple way to entrepreneurs and small business owners.

To preempt deepfake problems in the workplace, he recommended regular training sessions for employees. A good starting point, he said, would be to test them on MIT’s eight ways the layperson can try to discern a deepfake on their own, ranging from unusual blinking, smooth skin, and lighting.

Businesses should proactively communicate through newsletters, social media posts, industry forums, and workshops, about the risks associated with deepfake manipulation, he told DX Journal, to “stay updated on emerging threats and best practices.”

To keep ahead of any possible attacks, he said companies should establish protocols for “responding swiftly” to potential deepfake attacks, including issuing public statements or corrective actions.

How can a deepfake attack impact business?

The potential to malign a company’s reputation with a single deepfake should not be underestimated.

“Deepfakes could be racist. It could be sexist. It doesn’t matter — by the time it gets known that it’s fake, the damage could be already done. And this is the problem,” said Alan Smithson, co-founder of Mississauga-based MetaVRse and investor at Your Director AI.

“Building a brand is hard, and then it can be destroyed in a second,” Smithson told DX Journal. “The technology is getting so good, so cheap, so fast, that the power of this is in everybody’s hands now.”

One of the possible solutions is for businesses to have a code word when communicating over video as a way to determine who’s real and who’s not. But Smithson cautioned that the word shouldn’t be shared around cell phones or computers because “we don’t know what devices are listening to us.”

He said governments and companies will need to employ blockchain or watermarks to identify fraudulent messages. “Otherwise, this is gonna get crazy,” he added, noting that Sora — the new AI text to video program — is “mind-blowingly good” and in another two years could be “indistinguishable from anything we create as humans.”

“Maybe the governments will step in and punish them harshly enough that it will just be so unreasonable to use these technologies for bad,” he continued. And yet, he lamented that many foreign actors in enemy countries would not be deterred by one country’s law. It’s one downside he said will always be a sticking point.

It would appear that for now, two defence mechanisms are the saving grace to the growing threat posed by deepfakes: legal and regulatory responses, and continuous vigilance and adaptation to mitigate risks. The question remains, however, whether safety will keep up with the speed of innovation.

The new reality of how VR can change how we work

It’s not just for gaming — from saving lives to training remote staff, here’s how virtual reality is changing the game for businesses

Published

on

Until a few weeks ago, you might have thought that “virtual reality” and its cousin “augmented reality” were fads that had come and gone. At the peak of the last frenzy around the technology, the company formerly known as Facebook changed its name to Meta in 2021, as a sign of how determined founder Mark Zuckerberg was to create a VR “metaverse,” complete with cartoon avatars (who for some reason had no legs — they’ve got legs now, but there are some restrictions on how they work).

Meta has since spent more than $36 billion on metaverse research and development, but so far has relatively little to show for it. Meta has sold about 20 million of its Quest VR headsets so far, but according to some reports, not many people are spending a lot of time in the metaverse. And a lack of legs for your avatar probably isn’t the main reason. No doubt many were wondering: What are we supposed to be doing in here?

The evolution of virtual reality

Things changed fairly dramatically in June, however, when Apple demoed its Vision Pro headset, and then in early February when they were finally available for sale. At $3,499 US, the device is definitely not for the average consumer, but using it has changed the way some think about virtual reality, or the “metaverse,” or whatever we choose to call it.

Some of the enhancements that Apple has come up with for the VR headset experience have convinced Vision Pro true believers that we are either at or close to the same kind of inflection point that we saw after the release of the original iPhone in 2007.Others, however, aren’t so sure we are there yet.

The metaverse sounds like a place where you bump into giant dinosaur avatars or play virtual tennis, but ‘spatial computing’ puts the focus on using a VR headset to enhance what users already do on their computers. Some users generate multiple virtual screens that hang in the air in front of them, allowing them to walk around their homes or offices and always have their virtual desktop in front of them.

VR fans are excited about the prospect of watching a movie on what looks like a 100-foot-wide TV screen hanging in the air in front of them, or playing a video game. But what about work-related uses of a headset like the Vision Pro? 

Innovating health care with VR technology

One of the most obvious applications is in medicine, where doctors are already using remote viewing software to perform checkups or even operations. At Cambridge University, game designers and cancer researchers have teamed up to make it easier to see cancer cells and distinguish between different kinds.

Heads-up displays and other similar kinds of technology are already in use in aerospace engineering and other fields, because they allow workers to see a wiring diagram or schematic while working to repair it. VR headsets could make such tasks even easier, by making those diagrams or schematics even larger, and superimposing them on the real thing. The same kind of process could work for digital scans of a patient during an operation.

Using virtual reality, patients and doctors could also do remote consultations more easily, allowing patients to describe visually what is happening with them, and giving health professionals the ability to offer tips and direct recommendations in a visual way. 

This would not only help with providing care to people who live in remote areas, but could also help when there is a language barrier between doctor and patient. 

Impacting industry worldwide

One technology consulting firm writes that using a Vision Pro or other VR headset to streamline assembly and quality control in maintenance tasks. Overlaying diagrams, 3D models, and other digital information onto an object in real time could enable “more efficient and error-free assembly processes,” by providing visual cues, step-by-step guidance, and real-time feedback. 

In addition to these kinds of uses, virtual reality could also be used for remote onboarding for new staff in a variety of different roles, by allowing them to move around and practice training tasks in a virtual environment.

Some technology watchers believe that the retail industry could be transformed by virtual reality as well. Millions of consumers have become used to buying online, but some categories such as clothing and furniture have lagged, in part because it is difficult to tell what a piece of clothing might look like once you are wearing it, or what that chair will look like in your home. But VR promises the kind of immersive experience where that becomes possible.

While many consumers may see this technology only as an avenue for gaming and entertainment, it’s already being leveraged by businesses in manufacturing, health care and workforce development. Even in 2020, 91 per cent of businesses surveyed by TechRepublic either used or planned to adopt VR or AR technology — and as these technological advances continue, adoption is likely to keep ramping up.

5 tips for brainstorming with ChatGPT

How to avoid inaccuracy and leverage the full creative reign of ChatGPT

Published

on

Share this:

ChatGPT recruited a staggering 100 million users by January 2023. As software with one of the fastest-growing user bases, we imagine even higher numbers this year. 

It’s not hard to see why. 

Amazon sellers use it to optimize product listings that bring in more sales. Programmers use it to write code. Writers use it to get their creative juices flowing. 

And occasionally, a lawyer might use it to prepare a court filing, only to fail miserably when the judge notices numerous fake cases and citations. 

Which brings us to the fact that ChatGPT was never infallible. It’s best used as a brainstorming tool with a skeptical lens on every output. 

Here are five tips for how businesses can avoid inaccuracy and leverage the full creative reign of generative AI when brainstorming.

  1. Use it as a base

Hootsuite’s marketing VP Billy Jones talked about using ChatGPT as a jumping-off point for his marketing strategy. He shares an example of how he used it to create audience personas for his advertising tactics. 

Would he ask ChatGPT to create audience personas for Hootsuite’s products? Nope, that would present too many gaps where the platform could plug in false assumptions. Instead, Jones asks for demographic data on social media managers in the US — a request easy enough for ChatGPT to gather data on. From there he pairs the output with his own research to create audience personas. 

  1. Ask open-ended questions

You don’t need ChatGPT to tell you yes or no — even if you learn something new, that doesn’t really get your creative juices flowing. Consider the difference: 

  • Does history repeat itself? 
  • What are some examples of history repeating itself in politics in the last decade?

Open-ended questions give you much more opportunity to get inspired and ask questions you may not have thought of. 

  1. Edit your questions as you go

ChatGPT has a wealth of data at its virtual fingertips to examine and interpret before spitting out an answer. Meaning you can narrow down the data for a more focused response with multiple prompts that further tweak its answers. 

For example, you might ask ChatGPT about book recommendations for your book club. Once you get an answer, you could narrow it down by adding another requirement, like specific years of release, topic categories, or mentions by reputable reviewers. Adding context to what you’re looking for will give more nuanced answers.

  1. Gain inspiration from past success

Have an idea you’re unsure about? Ask ChatGPT about successes with a particular strategy or within a particular industry. 

The platform can scour through endless news releases, reports, statistics, and content to find you relatable cases all over the world. Adding the word “adapt” into a prompt can help utilize strategies that have worked in the past and apply them to your question. 

As an example, the prompt, “Adapt sales techniques to effectively navigate virtual selling environments,” can generate new solutions by pulling from how old problems were solved. 

  1. Trust, but verify

You wouldn’t publish the drawing board of a brainstorm session. Similarly, don’t take anything ChatGPT says as truth until you verify it with your own research. 

The University of Waterloo notes that blending curiosity and critical thinking with ChatGPT can help to think through ideas and new angles. But, once the brainstorming is done, it’s time to turn to real research for confirmation.
