Sriram Vasantharajan, Mazama Energy | theCUBE + NYSE Wired: Powering Tomorrow
Watch on YouTubeVideo summary
Sriram Vasantharajan, CEO of Mazama Energy, discusses a groundbreaking approach to solving the global energy crisis required to support the exploding demand from AI data centers. While conventional geothermal energy is limited by geography and natural conditions, Mazama utilizes engineered geothermal systems (EGS) to create reservoirs in locations where heat does not naturally exist. By drilling deep into the Earth's crust to access "super hot rocks," the company taps into a virtually inexhaustible resource that radiates from the planet's core. This method offers a massive potential, with estimates suggesting that extracting just one percent of this resource could provide enough electricity to power nearly ten times the current US consumption, effectively addressing the critical infrastructure pressures caused by gigawatt-scale factories in places like Texas.
The technology behind Mazama's breakthrough involves adapting existing oil and gas drilling techniques but repurposing them specifically for heat extraction rather than hydrocarbons. A key innovation is a patented refrigeration system that protects sensitive electronics and drill bits from melting at extreme temperatures of around 700 degrees Fahrenheit, allowing operations to proceed safely and efficiently. The company has already proven this technology in the field with a pilot project in Oregon that unlocked nearly five gigawatts of potential, a figure that exceeds the entire current US geothermal production combined. With plans to double this capacity to ten gigawatts through deeper and faster drilling, Mazama aims to provide a cost-competitive, reliable, and scalable energy source that can power regions like the Pacific Northwest independently.
Beyond the technical achievements, the project represents a unique convergence of generations and disciplines within the energy sector. The company attracts a diverse talent pool ranging from seasoned veterans retiring from the oil and gas industry to young engineers and scientists eager to solve complex problems without traditional academic constraints. This fusion allows for the transfer of deep engineering experience while introducing fresh perspectives on scaling new technologies. Major investors, including figures like Bill Gates and representatives from large energy firms, have validated the vision by betting on a tangible path to commercialization that relies on engineering ingenuity rather than unproven science. The momentum is further strengthened by significant Series B funding, which signals confidence in transforming this concept from a proof of concept into a global commercial platform.
Looking toward the future, Mazama envisions a world where affordable and secure energy is accessible globally by creating geothermal systems wherever they are needed, starting with the western United States before expanding worldwide. The ultimate goal is to establish a new industry category that not only fuels the AI revolution but also supports essential sectors like healthcare, transportation, and general electrification. A particularly exciting moment in their journey involved drilling two wells and discovering materials from the first well within the second, providing definitive proof that reservoirs can be connected effectively. This discovery underscores the company's mission to harness Earth's universal heat to power tomorrow, offering a sustainable solution that combines societal benefits with robust commercial viability.

Palo Alto studio connection Silicon
Valley and Wall Street. So I'm John F co
here with Dave Volante my co-host.
Hello I'm John Furry your host of the
cube. We are here at the cub's NYC
studio. Of course we have our Palo Alto
studio connecting Silicon Valley to Wall
Street as technology is the market. AI
infrastructure continues to grow. This
is our powering tomorrow series where we
talk to leaders who are bringing the
energy and the power to the AI
revolution. Also societal benefits the
grid. Everyone wants energy to feed the
AI. Girram Basatharo Jen is here. He's
the CEO of Mazama Energy. They have an
unique solution that could open up
megawws, gigawatts, terowatts. There's
whole another acronyms coming in.
Triron, thanks for coming in on our
powering tomorrow series as a leader.
You're doing some really innovative
things. Thanks for coming on,
>> John. Thank you very much for having us.
It's a pleasure and a privilege to be
here.
>> So you guys are doing something very
very unique and I think it's a real
breakthrough um in energy and clean
energy specifically, but it's also the
timing of what you're working on is very
important because everyone's talking
about the capex buildout for these
gigawatt factories. You see that in
Texas. Uh you see the demand for energy
for AI and of course we know that the
grid critical infrastructure
is under pressure. So there's all this
pressure for energy. We hear stats like
one gigawatt factory can power x number
of homes. So you're starting to see
engineers and and entrepreneurs go to
the constraints. The capital goes there
and so does the entrepreneurs. So
explain what you're working on. You have
a very cool solution. Talk about the
approach you're taking to energy.
>> Thank you.
We use an oldfashioned term geothermal
energy. When I mention geothermal, your
impression goes to Iceland and the
conventional systems that come. But
those kind of natural systems are
geographically constrained and cannot be
scaled. So what we do is engineer and
build the geothermal system cuz what
we're after is Earth's heat which is
universal. So we drill the wells, create
the reservoirs to extract, build the
heat there. So these engineered
geothermal systems is what mazama is
about. Building it where it doesn't
exist. However, there is something
unique in what we do. We go much hotter,
much more powerful temperature regimes
than what the industry is doing.
>> Talk about the the the geothermal
because the to the average person they
think volcano and they see the energy.
There is so much energy in the earth. T
take us through specifically how that
all works and why now? What's the
breakthrough?
>> Okay, let's talk about the price, the
size of what we call our super hot rock.
The US Department of Energy and the
Clean Air Task Force estimate if you can
extract just 1%
of this immense almost, you know,
virtually uh inexhaustible resource.
It's 4.3 terowatt of electricity. That's
almost nine to 10 times what the US
consumes today. It is a massive price.
It's always been there. And what we're
doing right now is creating the tech
platform to harvest it not just
reliably, but also in a very cost
competitive manner.
>> Talk about the safety and the efficiency
because clean tech, we've been covering
that since we've had the cube 17 years
now. And before that was a big sector,
but now there's breakthroughs. Talk
about the clean tech aspect of it, the
clean energy and the safety.
>> Absolutely.
>> It's not like drilling for oil or
anything like that. Or is it? Kind of
explain where this fits.
>> Yes, drilling is common. The difference
is we're just drilling for heat. We're
not drilling for hydrocarbons and stuff.
And heat is a universal commodity. So
these wells in fact we're just drilling
a well as I speak there in there
reaching about 15,000 ft and we're doing
it 80% faster than last year. So it is a
safe reliable operation that we can do
anywhere.
>> I'm looking at um the briefing document
and I really appreciate your team
supplying that. It's a global resource
as you say. I like the term super hot
rock. That's the word. Okay. Because
they're hot rocks. They're under they're
they're in the ground. They're deep. the
but the re it's pointed out that the
resources are vast and available. Speak
to that because this is one of those
things where it's abundant.
I mean is it always renewing itself? I
mean this science behind it and you know
explain the science behind the
renewability does it it's vast and
available and these super hot rocks if
tapped certainly will bring a lot of
energy blow away the scale that we
seeing now that's constrained.
>> Yes. The super hot rock potential is
more than all of the fossil fuels that
we have even discovered and it's a
perennial source because the earth's
core is constantly radiating this
energy. So as we withdraw it, a fraction
of what it does can power the entire
humanity for decades to come.
>> I have to ask you because this always
comes up when people say, "Oh, that's
such a great idea. How come no one's
done that before?" Um, and usually it
has to do with either the ingenuity
andor technology. This is a real
breakthrough. What's different now? What
got you here? What was the What was the
the path?
>> Yes, my path came through oil and gas.
For decades, me and my team worked on
some of the most complex engineering and
drilling problems around the world. So
when this opportunity came to repurpose
all that technology and learning and
science but to do something of a scale
that can rival what we have done before
and probably even exceed it was just
remarkable.
>> Talk about some of the energy around the
super hot rock when you get the the
heat. Um explain the process because
there's a specific method you guys have
>> when you go down and you you find the
the heat.
>> Yes.
>> Aka the energy.
>> Yes. Take us through that dimension. And
why doesn't things just melt? It's so
hot, you know, like, you know, the
equipment survive.
>> Yes. Equipment. Okay. The equipment will
melt if you don't have our secret
source. As you drill to these
temperatures, 700° F and stuff, the
electronics are rated for much less. So,
what did we did? What's our secret
source? You look around your house and
say, "What keeps things cool?" Your
refrigerator. So we took the
refrigeration principle and created a
patent that would keep our drill bit and
electronic school even when the
surrounding is at super hot
temperatures. So by putting a
refrigerator the existing conventional
drilling technology now we have adapted
to work at these temperatures. just give
us an idea of the scope of the kind of
um magnitude of energy you can extract
with the super hot rocks in comparison
to what people know today megawatt data
centers gigawatt data centers what are
some of the benchmarks that you see
coming out of say a deployment you have
a a site in Oregon right now u what are
some of the results that you anticipate
and compare the scope of the order of
magnitude difference
>> yes yes so last year we successfully
proved our technology in the field and
created the hottest ever engineered
geotherm pilot and what it did is
unlocked almost 5 gawatt of geothermal
potential to put that in perspective
that is more than all of the US
geothermal production combined this year
learning from that example we're
drilling deeper but also doing it much
faster and efficient it's going to
double the potential 10 gaw of firm
power that we and extract in a cost
competitive manner.
>> Obviously, there's a lot of people
excited by this. You guys have some news
that broke uh momentum is strong and
there's vast resource looking at the
map. You can probably put these uh on a
commercial basis out. Talk about the the
momentum the news the momentum behind
this your mission and then what it turns
into because I can imagine multiple
sites up and running producing enough
power to feed the grid in areas all over
the world.
>> Yes. I mean that is our vision is to be
creating geothermal where it was thought
not to be possible but then to create it
at a scale firm reliable way and cost
competitive. Okay we are about three
things. One is to be cost competitive we
means hotter the rock the more the power
density we can extract power but we also
need to do it faster cheaper and more
efficiently and that's what we're doing
it in the field. talk about the news
specifically the momentum behind um the
the support.
>> Yes, we announced our second round of
funding series B which is a immense
validation of our path to move from
technology proof of concept now to
commercialization of super hot rock.
We're excited to have a mix around the
table right now of technology innovators
like Bill Gates and Venode Kosla, energy
savvy builders like John Arnold and big
oil Konico Phillips and Shell coming in
validating our path and then helping us
scale to a commercial platform.
>> Well, you got great support. First of
all, the money is great. You need to
have the capital, but also you're
looking at a technological breakthrough
in science. This is a scientific
breakthrough. This is energy,
okay, that's going to help fuel the next
generation of society.
And you have smart people coming in.
These these people are have massive
degrees. They know the science behind
it. You must be attracting a ton of
talent.
What's the makeup of of uh your company?
What I mean, I'd want to work for you
immediately if I was in in in science
and be like, "Okay, this is a real
breakthrough." Talk about that piece of
it. It's not just the capital.
>> No. and the money that you could make.
>> Oh,
>> there's a technical mission here.
>> It it is it is all founded on an
innovative and integrated technology
platform. It's not enough if you just
have a drilling technology. What this
requires is the whole suite. Okay? And I
make a joke. I call it my team needs to
know every blade of grass in there about
super hotrop geothermal. How do you
drill it? How do you create these
pathways? And how do you get these wells
to produce for longer time?
>> You know, a lot of technical people love
sci-fi. I mean, I love I'm a big sci-fi
fan myself.
>> You know, you see the journey to the
center of the earth, you know, you see
volcanoes. You must attract a lot of
talent that have unique degrees. Is
there a certain pedigree or if I'm a
young person getting a PhD or I could be
in high school on a robotics club, I
could be doing things. What's the kind
of talent that's attracted to this new
opportunity? because you're a category
creator at this point for this market.
So, I'm sure there's multiple
disciplines,
chemistry, biology, science. What are
some of the things that you look for or
people might be interested in?
>> Let me repeat that it takes a village.
It's not just PhDs. Yes, I have one and
we have a lot of PhDs that do the
fundamental science but to transform
that science into engineering and stuff
takes all the disciplines from our
financial accountants to our procurement
to ensure our supply chain to the young
women and men who are coming in who want
to apply their skills to a whole new
problem. It's there. I mean I've had
people who had retired from oil and gas
industry
>> saying I'm coming out of retirement
because this is a legacy opportunity to
repurpose my skills to do something
clean.
>> It's exciting. It's a fusion between the
uh the generations and I've never seen
this in my career Chiron because
normally the young guard replaces the
old guard and that's the way it
traditionally is in tech. But when you
have these breakthroughs, it's almost
magical because you have people who have
been working on these areas. They come
together, but then the young guns coming
in. They may not be in the curriculum.
Geothermal is a category for energy.
There's no books yet. So like it's got
to be exciting for the younger
generation mentoring and then having
people come in who are just salivating
at the opportunity to get their hands on
the technology and apply what they've
been thinking about.
>> Absolutely. And it it works both ways.
We have our senior people who want to
transfer their knowledge and experience.
And then we have the young guns who are
going to make this into an industry and
scalable willing to lap it up. We have
all sorts of engineers, all sorts of
subjects matter experts. We need them
all,
>> I imagine. And they see the results
coming in. Yeah. We can now jump back
in. Seeing a lot of that on the AI, a
lot of systems folks coming in. Um, so I
love love that story. explain also the
the investors because you also have some
bigname investors that actually are that
know the technology. What's their
reaction? What does it mean for them?
>> This has been I mean they're betting
long. Correct. I mean this is a huge
challenge something that's been around
forever. But what they saw in this
vision is with the repurposing of oil
and gas and all these science
technologies there is a tangible path to
work this. This is not a science
problem. the heat exists. We don't It's
how do you engineer it to do it
efficiently and in a cost-effective way?
>> I mean, it's the best time to be an
engineer right now. We're seeing a lot
of areas not just AI but in energy uh
even on the finance side, you're seeing
a lot more engineering. Talk about the
engineering aspect of of this era we're
in because a lot of people who got their
PhDs were in college in the 80s 90s, you
know, this was all on paper and it's
becoming a reality in many fields.
biochemistry,
thermal energy that you're doing. I
mean, the AI revolution,
>> the tooling, the technology era we're in
>> brings that to life. I mean, even see
AI, some of the concepts that that are
breaking through on AI were I mean, I
learned in college. Yes.
>> But was we couldn't actually have
supercomputers.
>> That's correct.
>> So, you're having this whole
renaissance. Yes.
>> Of engineering.
>> Yes. And and what I tell these people is
apply to mazama because this is
fundamentals that are going to power not
just AI or the data centers but our
industry our electrification our
hospitals and stuff. So anybody there
who's willing to take a challenge solve
some difficult engineering problems
we're ready for you.
>> All right let's dig into that. What are
some of the things that you can put on
the table that uh would attract an
engineer who wants to solve hard
problems? Is it on the uh drilling side?
Is it on the on the mechanism? Is it the
extraction? What are some of the areas
that you're looking to focus on as you
got the support coming in, the momentum
with the with the capital, but also the
breakthrough? What what are some of the
things that someone would might want to
jump in on? What are some of the areas
you're you're focused on?
>> Like I mentioned to you, these are all
patented and innovative technologies. So
having different viewpoints and eyes on
it from physics to mechanical
engineering and the stuff will allow us
to make it more robust and repeatable
and scalable. So that's what we're
after. The efficiency, the reliability
of what we're doing and then scaling it.
>> Yeah, I imagine the distribution where
you put the plants. Let's talk about
what's going on in Oregon because I
think that's a real good template, the
work you're doing there. And we were
talking before you came on camera around
the grid in the Pacific Northwest.
This could actually fund energy
for the entire Pacific Northwest with
the potential. Talk about that impact. I
think this impact is I mean it's almost
mind-blowing
>> when we do the math when we look at how
much resource is there and how it can be
extracted in a sustainable way and
cutting it is so the magnitude of it is
the entire Pacific Northwest imagine 80%
can be powered from our site it's multi-
gigawatt and we're just starting to
unpack it in layers
>> when you talk about the vision take me
through the um the future. Go a couple
years out. What do you envision uh the
future to be? Your preferred future.
What would it look like? Multiple sites,
North America, US, global. What would be
your preferred future a couple years
out?
>> It's it's all of the above in a way.
This is truly this this breakthrough is
global. Has to be global because what it
leads to is energy affordability and
because it's a local resource, energy
security. Okay, we are going to start in
western US. It's ideal for this. But
from there, we want to start creating
geothermal systems all across the globe.
>> Sure. Congratulations on the funding and
certainly the momentum. Um, I guess my
final question is, has there been a
surprise for you? Like a a surprise
maybe you didn't think was going to
happen sooner or something that happened
randomly in the in the journey. Take us
through a moment where you're like,
"Wow, that can't believe that happened."
What would that moment be?
>> It It's a It's a geeky tech thing. Okay.
So, imagine you're drilling two wells,
pencils that go down to 10,000 ft,
>> and then you create the pathways to for
the water to flow. So, when we were
drilling our second well, we extracted a
rock sample and we actually saw
materials, the propins from the first
well in there. It's like the Rosetta
Stone looking at and saying, "You don't
need more proof than this. This is how
you can connect the reservoirs
>> and you got and that's the breakthrough.
Congratulations and we'll keep in touch.
Certainly a great momentum and a great
mission really is tied beautifully with
societal needs but also on the capital
side commercial side. Uh great
opportunity. Thank you for what you do.
Appreciate you coming in.
>> Thank you very much for this
opportunity. It was a pleasure having
this discussion.
>> This is powering tomorrow series with
the cube and NYC wired program and
community. I'm John Fer host of the
cube. These are the innovators solving
the problems for tomorrow. That's the
focus of this series, bringing that
energy and that financial capital and
the efficiency to power the world.
Thanks for watching.
