00:00:34.300 --> 00:00:39.060
Today, we're speaking with Patrick Racine, the co-founder and CEO of ChillSkin.
5
00:00:39.700 --> 00:00:48.600
The startup produces a heat mitigation solution called Polyfrost, which when applied to surfaces, makes them cooler under sunlight without the need for fuel or additional power.
6
00:00:49.260 --> 00:01:03.460
They're currently targeting their solution for the logistics, transportation, and industrial infrastructure sectors. Right, let's get straight into the interview. [upbeat music] Hi, Patrick.
7
00:01:03.980 --> 00:01:11.880
Can you tell us in your own words what adaptation problem your company exists to solve? Every generation has a problem it needs to solve.
8
00:01:12.860 --> 00:01:28.580
Ours happens to be how to deal with heat, not just the heat wave in the summer kind of heat, but the kind of heat that buckles highways, that strains power grids, that destroys food in our cold chain.
9
00:01:29.440 --> 00:01:43.280
And to date, our society's answer to that has been more air conditioning, more compressors, more energy, more, more, more. But what if there was a way to prevent this heat from forming in the first place?
10
00:01:44.080 --> 00:01:54.740
And that's what we're doing here at ChillSkin. We've developed this advanced material that allows sun-exposed surfaces to stay six degrees Celsius below ambient without using any energy.
11
00:01:55.320 --> 00:02:07.300
It's part of a family of product that's called passive radiative cooling. In fact, the World Economic Forum called passive radiative cooling one of the top 10 technologies to watch out for in 2026.
12
00:02:08.080 --> 00:02:16.340
Now, we, we did not invent passive radiative cooling. It's a physical phenomenon, and it's existed as long as there's been a blue sky above our head.
13
00:02:17.100 --> 00:02:25.860
What we've done is developed a way to, uh, to deploy it at scale, and that's what's making the difference here, and that's the challenge we're trying to solve.
14
00:02:26.380 --> 00:02:39.160
How does unchecked climate change make that problem worse over time, and what does it mean for the people and systems affected? Well, with the increased extreme heat events, there's more and more demand for cooling.
15
00:02:39.340 --> 00:02:45.180
And i- in our beachhead, which is the refrigerated transportation space, the space we're starting with, just, just to start,
16
00:02:46.280 --> 00:02:56.900
what it means is running, uh, trailer compressors harder, causing deviation in temperature inside the boxes, causing cargo losses, food losses.
17
00:02:57.720 --> 00:03:08.080
A- a- and as there's more and more extreme heat event, this is becoming more and more challenging for these users, and they're burning more and more diesel to keep the content cold.
18
00:03:08.860 --> 00:03:19.480
What makes you as a founder best positioned to solve this problem? Well, I, I'm gonna switch the question a bit. I, I don't think it's me as a founder that's making the difference. We've, we've built an incredible team.
19
00:03:19.920 --> 00:03:33.220
We've spent tremendous amount of time not just understanding our solution, but understanding our customers' systems and really understanding the impact we're having on those systems and, and that's what's making a difference.
20
00:03:33.520 --> 00:03:50.840
Uh, y- you can have the, the best solution in the world, but if you don't understand the interaction between your solutions and your customers' systems and how that, that can come together to bring real benefit, that's where, that's where problems don't get solved, and that's where solutions fail.
21
00:03:51.480 --> 00:04:02.480
What I'm tremendously proud of is how our team has spent immense amount of time and energy properly understanding our customers' systems to really see the real impact we're having for them.
22
00:04:03.420 --> 00:04:06.720
Tell us how your solution works to reduce climate exposure and vulnerability.
23
00:04:07.600 --> 00:04:17.579
Our advanced material allows the sun-exposed surfaces to stay six degrees Celsius below ambient temperature without using any energy, and that sounds quite amazing.
24
00:04:18.300 --> 00:04:30.720
It, it achieves that by having actually two physical phenomena that are exist- coexisting that normally typically don't coexist within one material. First, the material is highly emissive.
25
00:04:31.900 --> 00:04:42.380
Um, we have a material that emits heat naturally really, really well. Every object in the universe emits heat. Ours happens to be effective, very, very effective at emitting heat.
26
00:04:43.000 --> 00:04:53.300
And, and, and the challenge is that most highly emissive material are bad reflectors. So what we've done is we've engineered a highly emissive material to be naturally highly reflective.
27
00:04:53.820 --> 00:04:59.200
Um, i- in fact, it reflects almost all of the solar energy across the entire solar spectrum.
28
00:04:59.720 --> 00:05:09.920
Um, like the paint, the white paint behind me would reflect about 75% of solar energy, most of the visual light, which is why we see it as white, but not as good on the infrared and the UV.
29
00:05:10.520 --> 00:05:18.540
Across the solar spectrum, that paint reflects 70, 75% of the solar energy, which means it absorbs the balance, 25%.
30
00:05:19.000 --> 00:05:29.520
Our coating can reflect as much as 97 and a half percent of solar radiation across the entire spectrum, meaning we only absorb two and a half percent, 10 times less than white paint.
31
00:05:30.100 --> 00:05:38.820
And the two and a half percent that gets absorbed is less than the natural emittance of the material. So we keep emitting more heat than the two and a half percent that gets absorbed.
32
00:05:39.260 --> 00:05:45.060
So that leads to a net negative heat balance. We shed more heat all the time than we absorb, and we can stay sub-ambient.
33
00:05:45.740 --> 00:05:59.240
In our customers' systems, less heat load means less pressure on temperature load on the boxes, less runtime of the refrigeration units, less higher RPM, less wear and tear on the equipment, and less fuel use.
34
00:05:59.860 --> 00:06:04.580
Who is your customer, and what does it take to get them to see that this is a problem they should pay to solve?
35
00:06:05.520 --> 00:06:20.380
In our beachhead, uh, our customers are refrigerated transportation fleet, folks that are carrying food or pharmaceutical from point A to point B. And, and, and these folks burn a lot of diesel to keep the content cold.
36
00:06:20.620 --> 00:06:30.160
They, they burn about 10 to $12,000 a year of diesel just to keep the content of a trailer cold over, over a year. So, so they know they spend a lot of energy on that.
37
00:06:30.720 --> 00:06:40.440
With extreme heat event, they're actually having challenges where sometimes the equipment just can't keep up with the heat and they lose cargo because of these excursions into super high temperatures.
38
00:06:41.560 --> 00:06:53.220
So convincing them they have a problem is not that hard. They, they know they have a challenge, and the solution historically has been to just run the equipment harder, which reduces the lifespan of the equipment.
39
00:06:54.440 --> 00:07:03.840
The, the challenge and what we spent a lot of time understanding is the data behind that. How do we look at data to properly show real return on investment for our customers?
40
00:07:04.240 --> 00:07:12.620
A- a- and these returns are, are phenomenal, depending on the geography they run it and the age of their box, the, the, the payback, it can be sub 12 months.
41
00:07:12.660 --> 00:07:24.480
It's typically 12 to 18-month return on investment for that project, so a very, very compelling ROI. It also saves about five tons of CO2 per year per trailer they have.
42
00:07:24.860 --> 00:07:34.320
So a fleet that has, say, 1,000 refrigerated trailers in their fleet can save 5,000 tons a year of CO2 by rolling out our solution across their fleet.
43
00:07:34.600 --> 00:07:43.540
So a lot of compelling reasons to do it, some great benefit on the CO2 emission reductions that are paid for w- really, really compelling ROI.
44
00:07:44.720 --> 00:07:52.160
What's the hardest thing to explain about what you do, and how do you explain it? The hardest part is actually not our solution itself.
45
00:07:52.240 --> 00:08:00.140
I mean, we reduce thermal load on systems, and if there's less thermal load, then there's less cooling required. Th- that part is simple.
46
00:08:01.220 --> 00:08:11.480
W- what's the hardest in the environment we work in, in the refrigerated trailer space, is at that all these trailers run at varying efficiencies as a baseline within a fleet.
47
00:08:11.880 --> 00:08:27.500
Um, there's a lot of variables that affect how these trailers operate, uh, s- from geography they run in, to age of the boxes, the efficiency within the controllers, to the software that's in the controller, to operator behavior, how the drivers operate these, these units.
48
00:08:28.180 --> 00:08:34.000
So, so one of the challenge is to first collect the proper data to show them the real impact.
49
00:08:34.060 --> 00:08:47.000
A- a- and that's, I think, where we've, we've, we've done something pretty special, and we have a team that can really help the customer understand their own data so that they can make better-educated decision that drives the right behavior change.
50
00:08:47.880 --> 00:08:56.980
Tell us a moment where you felt close to giving up, and what helped you push through that? I wouldn't wanna say we don't have problem. Um, we have challenges.
51
00:08:57.100 --> 00:09:09.720
There's been a lot of things we had to solve for in the way we scale the technology and in the way we deployed it, uh, at scale in the field. But, but I don't think I was ever close to giving up. Um,
52
00:09:11.060 --> 00:09:21.380
what keeps me motivated are, are, are two front. O- o- one is the problem we're solving is a real issue. We will have to deal with extreme heat event.
53
00:09:22.040 --> 00:09:33.900
Uh, resiliency through climate change is a real thing a- and we need to solve for it. And, and that drives me and that drives the rest of our team to do that. W- which is the second part of what drives me.
54
00:09:34.460 --> 00:09:43.960
We've built this incredible team, uh, people that are passionate about changing the way the world thinks about cooling. Engineers, polymer scientists,
55
00:09:45.200 --> 00:09:57.280
experts in their field on the operations side, on the scientific side, with the one common thread that they're all very, very passionate about what we're doing. A- a- and that's what keeps me going. Uh, it...
56
00:09:57.980 --> 00:10:04.040
The, the, the challenge that we're solving is, is so big that finding the motivation isn't hard. A- a-
57
00:10:05.500 --> 00:10:19.220
and in some ways that, that, that g- makes us a, a really, really passionate place where people work, where people challenging each other, and where we find the best solution to help the world change the way they think about cooling.
58
00:10:20.040 --> 00:10:23.900
What do you know now that you wish every climate adaptation founder knew when they were starting out?
59
00:10:24.740 --> 00:10:37.360
I think it's important to recognize that we go through economic cycle and geopolitical cycles that changes, um, how businesses make decisions regarding climate adaptation.
60
00:10:37.760 --> 00:10:47.700
Ultimately, we'll have to do something, but, but as we all know, there's periods of times where there's more headwinds and periods of time where there's more tailwind. I think
61
00:10:48.720 --> 00:11:04.260
what I've learned over the last few years is that you need to have a solution that is helping solve for climate adaptation and climate change resiliency, but that your solution needs to also have good unit economics.
62
00:11:04.660 --> 00:11:21.120
You need to have solutions that allow people to be excited about it, whether it's to reduce their CO2 footprint, whether it's to protect the heat load on their system and the cargo they transport, or whether they're just trying to bring a compelling ROI to their business.
63
00:11:21.800 --> 00:11:35.080
If you can find solutions that are not just helping on the climate resiliency but also providing compelling ROI, that's where the magic is and that's where the, the, the solution takes off, and that's been our experience.
64
00:11:35.840 --> 00:11:48.280
Where do you see capital flowing into adaptation, and what areas is it not flowing into but should? That's an interesting question. Uh, as a CEO, uh, of a climate tech, uh, startup,
65
00:11:49.440 --> 00:11:56.820
you do have to worry and spend time on financing. Obviously, that's, that's what... that's the, that's the fuel that drives, uh, the business.
66
00:11:58.160 --> 00:12:07.440
Probably not spending enough time outside of our own ecosystem to understand where the places it should flow that it's not. So I'm, I'm probably not the best person to ask.
67
00:12:07.960 --> 00:12:19.800
I, I have to say that the investment community has been incredibly supportive of what we're trying to do. We have a compelling solution with compelling unit economics a- a- and that's working.
68
00:12:20.380 --> 00:12:31.040
I, I, I would be the wrong person to ask where it's not flowing that it should. Is there anything else you'd like our audience to know about your company and about adaptation tech in general?
69
00:12:31.860 --> 00:12:41.740
Ultimately, Chill Skin isn't a refrigerated transportation solution company. You know, our, our solution is actually much broader than this.
70
00:12:42.300 --> 00:12:49.980
We, we picked the refrigerated transportation space as our beachhead, uh, for many reason. One, the unit economics are compelling for our solution.
71
00:12:50.200 --> 00:13:04.840
We have some unfair advantages in our solution that makes the solution really well-tailored for the transportation space. We don't make cooling equipment. Our, our, our job is not to cool the world.
72
00:13:05.720 --> 00:13:19.580
What we do is we make cooling more efficient, more resilient, more affordable, and more approachable, and that's what we do at Chill Skin. We help cooling systems
73
00:13:20.680 --> 00:13:23.800
keep up with the demand of this warming world.
74
00:13:25.140 --> 00:13:37.100
And we're looking continuously for more opportunities to help in our beachhead first, but then move on to the other systems to keep changing the way the world thinks about cooling.
75
00:13:37.100 --> 00:13:53.980
