¶ AI Demand Surge and Grid Challenges
There's a lot of debate about where exactly data center electricity demand is headed, but we know it's steeply up and could account for more than ten percent of US demand in the next few years. That's up from two percent a couple years ago. That's an unbelievable lead. And that leap really, if the US has to stay in the AI race, has to happen in the next four to five years.
KR Sridar is the CEO of fuel cell maker Bloom Energy. About a third of the company's solid oxide fuel cells are sited at data centers. We're talking hundreds of megawatts with that number growing quickly. So KR knows the industry well, and he's never seen anything like the current AI infrastructure boom. It's the speed and the scale. I truly believe that this is a circular trend that's going to continue for well over a decade.
Data centers are now being planned and built faster than the electricity system can handle. That has sparked another debate about the role of on-site generation and whether data centers will be built off-grid. Now, some folks argue that co-located behind-the-meter resources will be rare. And that the smartest economic move for data centers will be to connect to the grid, not walk away from it. KR believes deeply in the importance of the grid.
But he also thinks that on-site solutions, including fuel cells, will be critical for building infrastructure at the pace of AI expansion. What the centralized power plants and the electric grid did to humanity in the twentieth century is nothing but unbelievably amazing. That model still has a place because electricity is the ultimate perishable and having that large flywheel called the grid is very important. So
It's an and and not an or. However, when you go to data centers, here's what happens. There are many misalignments between data centers and the grid. A data center consumes DC power, the grid sends AC power. And the quality of the power on the electricity system, which shifts depending on loads turning on and off, and changes to the generation mix, is not anywhere near what a data center can accept.
What do you do? You put all these band-aids, make it high quality using UPS quality power. Step it down from high voltage to medium voltage to low voltage. All the transformers, all the power conversion devices, they're all band aids because they are taking a mechanical age electricity and trying to adapt it to a digital age computer.
¶ Fuel Cells as Digital Age Power
A fuel cell is a solid-state power device that KR says is purpose-built for a digital facility like a data center. He compares today's power strategies to trying to build a faster horse and buggy when we really need a car for the AI era. When you use bloom, you have a one-step process. When you use a conventional combustion technology, you use a six-step process. The horse is consuming a lot of water, it's consuming a lot of hay and a lot of other things.
I'm Stephen Lacey, and this week we have a conversation with Bloom Energy CEO K.R. Sridhar about rapidly changing power strategies for data centers. This conversation was recorded live as part of Latitude Media's Frontier Forum series. The data center industry is investing trillions in infrastructure while up against permitting timelines and grid constraints. I talked with KR about customer pain points, the unique power demands of AI data.
centers, and why on-site generation will be critical for winning the AI race. So we did a uh survey two years ago and now. And eighteen months ago the survey, you know, like respondents said, one percent of the survey respondents said they will use on-site power that is not connected to the grid. Two months ago when we did the same survey, 29% of the respondents said they will use
on-site power without being connected to the grid. So the sentiment is changing enormously simply because of lack of availability of the power and understanding that we have to use this. So this AI movement. is forcing data centers to finally say The digital age needs digital electrons coming from a digital source. I think once they get used to this and understand all the advantages of this digitally purpose-built on-site power, they're not going to switch back.
¶ Grid vs. Off-Grid: The Economic Debate
Let me take the other side of that. I think that people who believe that most of these data centers will be grid connected would say. The grid offers scale and optionality that no off-grid system could potentially match. Um it's much more cost effective. You have to overbuild the system for an off-grid Data center. Um, and that there's a lot of grid capacity left that you just need to get creative to unlock that grid capacity.
What do you say to those arguments about why off grid data centers may not uh blossom in the way that you're painting? I'm going to surprise you by saying that I would agree with those arguments for a very simple reason. If you have excess capacity in the grid,
And you can get that without putting that on your balance sheet. Why would you be stupid enough to put that on your balance sheet and take that responsibility yourself? Absolutely, yes. That's exactly what all the data centers have been doing so far. But here is why. The Commons, which is the US taxpayer and the US government, built this excess capacity in the grid that was paid for by the ratepayers, one way or another, either through taxes or through their bill.
That grid has excess had excess capacity, so the data centers were able to use it. Now if the grid were to build excess capacity purely to meet this huge demand, and expects the taxpayer to pay for it so the hyperscaler can benefit, that politics is never going to fly.
So the so the idea that somehow data centers will go and build their own on-site power if the grid were available is a fallacy. The notion that the grid, the commons, will somehow build all this capacity so one or two users can use all that capacity at the expense of everybody else, is also a political wish, which I don't think will happen in reality.
¶ Speed: The Key to AI Supremacy
Um, and then what about just speed in general? How much is speed to power, the phrase of the moment? How much is that going to drive the off-grid approach? Uh that is going to be the key. Uh the truth is this is a true race. It's a race between corporations trying to get supremacy. It's a r race between the Western world and the like rest of the world competing for AI supremacy. One thing that everybody will agree is being number two or number three is not an option.
Speed is going to be everything. And there it's just simple knowledge for people who understand the grid that you cannot build the grid at that speed, no matter what you do. You know, the common refrain is if only permitting and permissions go away. Okay? Yes, that is a big, large issue. But Imagine somebody waves a magic van uh you know like you know like wand, the king, and I can build high voltage transmission lines running straight over your house and you have no right to object to it.
So what? What's the amount of copper needed? What's the amount of transformers needed? What are the leads times for it? Where are you going to get that from? Where are the skill sets to build these things? How much capital is required? How fast will that happen? Realistically, over a five, six, seven year period, it cannot catch up.
with the demand base that exists out there. That doesn't mean that we shouldn't upgrade the grid. That's why I started off saying the grid has a very important place. It's an all of the above strategy. We should be investing heavily in optimizing the grids, the things that you talked about. Can we use AI to make the grid better? And extract more out of less, right? Can we make it more efficient? Can we figure out other ways of optimizing it? Can we add
More transmission? Can we add better technologies to remove the bottlenecks where they exist and get more out of the grid? The answer is yes. But is that the solution? No. It is part of a solution.
¶ Lessons from Industrial Captive Power
Tell me about what other industries you look to where this could where this is a model. Are there large industrial loads that you see that have accomplished this? You know, when I look around, there is not a single industry that builds factories. that have very high power demands that doesn't have captive power. Okay, let me walk you through it. You take metals
Whether it's a steel mill or it's aluminum, if you go to an alcova plant in Indiana, they'll have a cap two power plant that's a few hundred megawatts. Because that kind of load, they cannot depend on the grid. If they were to do a shutdown for maintenance, And you suddenly drop hundred megawatts to two hundred megawatts off the grid, what happens to the grid? You cannot do that.
It has to be captive power. You go to cement, large cement plants, wholesome. If you go and look at it, they will have their capital power plants. But then you go to refinery. Same thing. But here is what happens. Here's another reason why they do it. It's not just because the Lord is so large.
You know, number one, you get the reliability and resiliency you need when you have a captive power plant and not when you depend on the grid. These are continuous processes. If they shut down for whatever reasons that happen in the grid, That cost of in-process inventory everything is too high, right? Number one. Reliability and resiliency. Number two, there are synergies that come from keeping that captive power plant right where you use the power. Here is why.
A refinery, for example, will use the off-gases that are coming out as a fuel into their power plant, and they can get better economics. A steel mill, a cement plant, same thing. Then you look at paper mills. Paper mills do the same thing. You go and look at chemicals, pharmaceuticals. It's the same. Anywhere you have seen an extremely large load in a factory, it's a CAP2 power plant. We are finally building high electricity intensity AI factories.
These are these data centers are AI factories. They have been the exception and not the rule. They are now going to have to follow the rule.
¶ Future AI Microgrid Architectures
So uh I I definitely take your point for the all of the above approach. And you know, you've said that this is not a winner-take-all market. So if we apply that to the actual on um groupings of on-site technologies. For uh these data centers, what do you expect to see when we look at fuel cells, gas turbines, renewables, eventually nuclear? How do you imagine them all fitting together? What kind of system designs are you currently seeing?
These are, you know, it'll be all of the above. It'll be all of the above and more, okay? Uh new things that come along. And so what I would say is Microgrids supporting such infrastructure will definitely have a multiplicity of generation sources. Each one comes with very different attributes. And you may need particular attributes depending on what your end need is. So as as soon as you start purpose building for your need.
you're going to exactly tailor it for the needs that you have. And so you can imagine for some extremely peak loads there being some engines or turbines. For a steady base load, there being a fuel cell because uh we'll be the most efficient from a fuel perspective and not create pollution. Zero pollution, right? Air pollution. That's super important for an AI factory because unlike a refinery, unlike a cement plant,
which can be loc which will by definition only be located far away. And inherently they create so much pollution that having just a captive power add to that pollution is de minimis. Unlike that, a AI factory being built in a population center, especially for inference, cannot afford to have air pollution.
So that becomes an extremely important aspect. Then you got the load swinging up and down. For that, you're going to have a variety of storage technologies, from batteries to flywheels to ultra caps to supercaps. they will all become part of the microgrid. And how you adapt it, what particular technologies you use will depend exactly on what kind of a data center it is, what does its load profile look like.
And it has to be tailored and met perfectly. So I think we are in the dawn of a reimagining electricity and how it is delivered to a customer.
¶ AI Workloads: Inference at the Edge
Yeah, that brings me to another question. It's kind of a two-part question. One was on the differences between training and inference workloads. And is it possible that there is even more upside to growth than we previously thought? Uh based on historical data, including our conventional CPU data centers. And if you go back to any form of human use.
of a new technology, a new tool, what you see in history is while things start in a very centralized fashion far away, ultimately the value is only created and the growth comes when that technology comes to the edge. Closer to where people are, closer to where machines are, closer to where people are. And that is the predominant use. That applies to computing, that applies to you know telephony, that applies to uh you know everything else. So what do I mean by that?
Today, most of the AI load we are all focused on and are talking about is the hundreds of megawatts to a gigawatt kind of a data center for training. The total capacity of that will keep increasing over the next eight to ten years. In terms of percentages, While today the training is ninety percent of the AI load and ten percent is inference or somewhere in that neighborhood, three to four years from now I predict that ninety percent of the load will be inference and ten percent will be
training, even though the ten percent in training then will be significantly larger than the ninety percent training today. That's what I mean by proportionality. They'll both grow, but proportionally this is where it'll be. The inference data centers for AI Unlike the CPU data centers of today that are one to ten megawatts typically on the edge, are going to be somewhere between five to thirty megawatts on the edge.
So if you live in Austin, if you live in Dallas, if you live in Chicago, if you live in Manhattan, if there are hundred inference data centers that need to come that need ten to thirty megawatts of load. God bless you if you went to your local utility and asked them for that load and they're able to provide that to you. If you thought transmission was a problem, wait till you figure out what distribution is. That's the surface streets, right? Transmission is your highway.
If you if you think the highways congested wait till you get to the surface streets to see what the surface streets are doing, right? So you need on-site power for that. So I completely agree with Arman that that's going to be a huge growth area. And the beauty of our technology, which is modular scalable. With no compromise in efficiency or performance or reliability, whether you do it in five megawatt chunks or fifty megawatt chunks or five hundred megawatts.
That advantage that we bring again is the car unlike the horse.
¶ Addressing AI Power Delivery Pain Points
What do you what are the other pain points you're seeing from customers when it comes to power supply and delivery? Um are there any others that we haven't touched on that you think are particularly acute? Yes. Um the uh data center customers, the AI practitioners know this extremely well. The AI load, unlike the CPU load, is very volatile. It has Milliseconds, seconds, and minutes variation that go from 10% of a load to 100% of the load.
So you're talking about swing if it's a hundred megawatt data center as an example, you're talking about the load swinging from ten megawatts to hundred megawatts up and down. And some of those variations happen in millisecond frequency, some of them happen in seconds frequency, some in minutes frequency. And the amount of back-end band-aids that they are putting. to deal with this as well as the harmonics it creates
because of because of converting AC to DC have all become very large pain points. Number one, with our architecture of being able to provide DC. it becomes easier. That's one pain point. The second pain point that they are working on as we speak. Shifting the mindset to a eight hundred volt D C bus going into Iraq. Let me explain this to you.
When you are a large power plant that produces 50 megawatts, 500 megawatts worth of power, because so much power comes out and think of it as a pipe, the wire as a pipe. Uh think of water flowing in it and think of the total power coming in as the amount of water the the mass of water coming out.
You can either increase the pressure or increase the diameter to increase the flow. Because copper gets very large if you keep it at low voltage, they only bring it out at high voltage. You have to convert them all. And that process In our system is completely obviated because we can natively provide 800 volt TC going to the grid. We think that's where the world will go.
So that's a huge thing that is a pain point, but we have an elegant solution to solve that problem. The third pain point that they see. is cooling. The amount of cooling load necessitates that it's a liquid cooling that has to happen in the data center ract. And there again we have an elegant solution for them.
¶ Sustainability and Future Fuel Pathways
So when we look at the uh needs of customers, what they're looking for, do you see any tension between the speed to power and sustainability goals? And do they have any concerns about a gas strategy? I would say for pretty much all the data center operators today, the sustainability goal has shifted from being in the top three to being in the bottom three. However, if you offered them a pathway. to I can give you the quick power today.
But I can future proof you and I can give you add ons that get you to net zero or extremely low carbon footprint. They're super interested. They still want to do it, but they will not do it at the expense of waiting for power. Okay, that's where that's where the sentiment is. That's where Bloom plays really well. Because we consume less fuel with natural gas, we have a lower carbon footprint compared to any other on-site generation technology.
And without natural gas, we are we are not gonna be able to power the AI revolution. That's a fact. Okay. That's a fact. And so we are lower comfort. However, Because of the uniqueness of our technology, and your viewers can go watch that on our website. There's a very good explanation of carbon capture. We put out a very clean stream of carbon dioxide coming out. So the
Our users can capture the carbon dioxide coming out of our system and sequester it. And I think the world will get to that place very soon. So that's one way of zero carbon. Should a green molecule become available in the future? hydrogen, ammonia, RNG, biogas, you name it, and it'd be available in large quantities. Our systems are already prewired for that. You don't even have to tell us. You can feed that gas in.
And we will happily accept it and produce the electricity. So we are future proof. So in other words, think of us. as we are giving you a five G phone now. even though you don't have 5G in your neighborhood, but you don't have to wait for 5G to come to your neighborhood to use it. You can be using your LTE or 3G right now. And when 5G comes, it automatically switches over.
Our systems are built for a zero carbon molecule, but that molecule, when it comes, the customer can switch, but they don't have to wait for it to come. Mm-hmm. Uh and I remember when um Bloom first emerged, there was a lot of talk about the potential of using green hydrogen in these fuel cells. And you know, hydrogen ha green hydrogen has been very difficult and expensive. There's limited supply.
Um, and you talked about carbon capture, this partnership with chart industries, I believe. Which comes first? Car uh carbon capture at scale or green hydrogen? Carbon capture at scale, hands down, for electricity generation. So it depends on what you're asking for, right? The green hydrogen going into green ammonia coming from certain places going to produce fertilizers and other hard to abate industries. That would make sense. It would not make sense.
To make a green ammonia and use that for electricity generation because the world is short on electricity. Green hydrogen is produced by bottling electricity. Why would you bottle something when you have current shortage? You don't save money if you can't feed yourself today. Who is asking for a carbon capture? Are they corporate customers with sustainability goals? Are there other reasons? Is it primarily the folks who have clean energy targets and are now burning more gas? Look, I think
Most corporations want to be responsible. You know, nobody wakes you know, I I can't, you know, I've not met a CEO yet who's waking up in the morning saying, I want to add to climate change. Okay? That's that's not the goal of any corporation. So when we tell them that we have this solution, they say as long as
It meets the economics. You know, they're willing to pay a premium. As long as it meets the economics and it can be within scale, if you don't slow me down, I'm willing to buy that solution from you. That we have heard across the board from everybody. across the board from everybody. So what we are seeing is every data center customer
is super interested in our carbon capture solution if they are deploying that solution in a region where the geology is suitable for sequestration. They're all interested. Now what they also want is speed. And the solution we offer is Carbon capture and sequestration is a bolt on to our technology. We will provide you the power with the lowest carbon footprint today, two years from now, when everything else is ready and available, like the class six wells, all the pumping.
All the technology with chart ready to be implemented, we will bolt that on for you, and they're very happy to sign on to a solution like that.
¶ Resilient Supply Chains and Customer Solutions
We are of course in a wildly different trade environment now. And I know that you had worked over the years to move your supply chain away from China. Can you talk about your advantages and any risks you have in your supply chain currently? And you know, are any of the major policy changes changing the way you're procuring materials and equipment? So uh when I started Bloom twenty four years ago.
The idea was very simple, right? Centralized systems with centralized directive managed by very few is a command and control communistic time you know kind of approach. The distributed is democracy. So we were building a democratic electrical system with a distributed system. That's that wasn't our objective. So for that reason, that thought process permeated through everything we did. We said we want to build a supply chain where no one single region
can solely choke a supply chain for growth. So we only picked materials, we only picked processes, we only picked supply chain partners. As long as we could geographically diversify across the board and not create any tensions in that system, because the goal of the company was one day to be able to provide this around the world and create energy abundance.
It it was built at the very lofty goal. So so therefore we set it up that way and never constrained ourselves to any one country from the day we started. Today when we look back, that was a very good strategy. from a where the world is going and the interdependence and that interdependence becomes unhealthy if that interdependence is on only one person and it's a one way. That's not interdependence anymore.
And and we don't have that, number one. Number two, the question you asked Unlike other energy generation technologies, uh if you take Turbines as a class, engines as a class. You go to the second third tier suppliers, you will find common bottlenecks. Unless that second third tier is able to grow. The rest of them can't grow. It'll it's only a matter of allocation of between the people who consume it, who's going to get more and who's going to get less, even as they grow.
We are decoupled from that supply chain because of the completely different way that our technology works, right? And if you think of copper and transformers and things like that, because we natively produce DC power at the right voltage, we are just eliminating the need for a lot of those materials that are in short supply. So if you're trying to take the limited amount of materials available and say, where can I get the most bang for my buck, you will see that.
our technology and our supply chain and how we think about that entire value stream will provide a lot more power with the same amount of copper compared to any other technology. Mm-hmm. And are you seeing sufficient gas pipeline capacity? Uh the gas pipelines and the availability of gas is there. In fact, as you very well know, we are exporting a lot of LNG out of the country. So clearly we have excess of that.
Now, in terms of the pipeline coming to exactly where your location is, from the medium pressure pipeline to the last mile distribution, there could be you know you know issues there in that Uh there in terms of adding that infrastructure, depending on what state you live in, it can be a matter of weeks or it can be a matter of years. you know, if you if you if you happen to live in New York City or the state of New York, uh, you know, two years ago where it was completely anti pipeline.
Um, that would be very hard to get. But in other states it's very easy to get. But I think that's all changing. That attitude is changing, getting to reality of this is the cleanest way we can do it, and better cannot be the enemy of good. Let's talk about customers a little bit. You've deployed um a lot of capacity with um customers like Equinix and AEP. You've inked to deal with Oracle to deliver on-site fuel cells.
for cloud data centers in I think only ninety days if if that's right. Yes. Um and that's, you know, unthinkable when we think about traditional grid connections. What are customers asking for? Are they are they currently supplementing with grid power or are they truly looking for these um on-site, off-grid solutions? All of the above.
Anytime a customer can connect to a grid, they would want to and we would recommend that they connect to the grid because that's that's insurance for almost nothing. Why would you not take You know, it's an option. Why would you not take it, right? So wherever the grid is available, even if we are primary power and we have all the reliability, it costs almost nothing compared to the entire data center spent.
to be able to get that, you know, connection. But when that connection is not available, our solution offers a highly reliable option where they can go without it compared to any other solution out there. So there are customers. So today I would say we have a mix of both. Traditionally over the last few years, if you looked at it, even though we were the primary source, even though we were mission critical.
uh in many cases they were connected to the grid. But we have an example, 2013, when we did eBay, of r having run that data center without losing power even once for over a 10 year period of islanded solution where we were the only solution. The the grid was connected but it didn't have the capacity that they needed. Bloom offered that capacity. So uh for us, islanded more That's what the system was designed for. It's very easy. It's not an afterthought.
¶ AI Optimization and Global Race Urgency
I want to turn now to the actual use of AI to model and optimize these systems. Uh, can you talk about how you're using AI for digital twins and what that does to the actual performance of the systems and how you're modeling them at at these large data center sites? That's a great question. So um If you just think about how we planned it and when we look back, we're actually very happy that we did it that way.
Each one of our Lego block modules, I'm sure your uh you know, like viewers have seen what a Bloom power module looks like. They they look like big refrigerators. They produce about Uh, you know, 65 kilowatts, and there are 64 little fuel cell stacks sitting inside. Think of them as your chips. Every chip is wired and is providing its health data regularly to us wherever in the world it is.
That's how we did it from the day we shipped our first system in 2008. So our fifteen hundred megawatts or one point five gigawatts worth of install base. is shipping us billions of data every day on how it's performing. Very lately we started calling them digital twins because the world, you know, the world created that terminology. So we have a digital twin for every fuel cell stack that goes in every system. Feeding us data.
We used heuristics and machine learning and other knowledge to be able to extract and learn from it. And that was part of our innovation cycle. Every system we installed. Was also a lab experiment for us, giving us data, allowing us to learn and become better. We are a learning organization. Now, Look at what AI has done. With that data today, not only can we learn what is working and make something better.
We can probably real-time manage the performance of each one of those little refrigerators, slightly different from the next one, just customized for what it can do and extract more out of it. I think it's a phenomenal opportunity and we are all over it. I wanna go back to the urgency that you expressed earlier about
Why we need to do everything we can to dominate the AI race. Talk about the consequences of not scaling fast enough. How do you see the US stacking up globally and You know, what are the positive outcomes if we can get this right? So When you look at the AI race, it's not just about intelligence and information and number of roles.
manual processes we do today that can be automated and therefore improve productivity. If you just take that productivity gain alone, we can improve our GDP growth by a couple percentage points.
Right. That would mean, you know, thousands of dollars in the pockets of every average American, every average person that lives out there. So economically just imagine what it creates from a GDP growth and and and the like and the trillions of dollars it puts into our economy and what does so that's one simple way to think about. The next thing to think about is not just business processes.
But we are living in a sensor ubiquitous world. Every physical device has sensors today and it's affordable to put these sensors, IoT, right? The ability to use IoT properly Using physical AI and how to make everything perform better, become more predictable, last longer.
changes every aspect of every industry. Whoever wins this race is going to dominate in manufacturing, is going to dominate in materials processing, is going to dominate then using all that information in the speed of R and D for any future technology. So I think your viewers will agree that if we lose our technology superiority, we will lose our economic superiority. That hinges on AI. Now take another layer.
National security. Wars are going to be fought and won by AI superiority, not by boots on the ground superiority. So it's a national security issue, it's a economic prosperity issue, it's about who controls the numbers issue. Now the world pretty much is between a free world and a not free world. Who wins this race is going to dictate which way the rest of the world is going to be dominated by.
And that's a scary thought if you if it's if you think we can be number two. It's absolutely scary to me that we can be number two. So so that's where I would say policy notwithstanding Um, doesn't matter who is in Congress, who's in White House, there'll be one thing that every every government is gonna agree is we cannot afford to not win the AI race.
