Liquid cooling has become one of the most important technologies in the rise of AI. Powerful new AI server hardware throws off a lot of heat, pushing past the limits of most traditional air cooling. This has driven a surge of acquisitions in the cooling sector, and none bigger than Ecolab's $4.75 billion deal to acquire liquid cooling specialist CoolIT Systems.

In this episode of Data Center Richness, host Rich Miller sits down with Jason Walker, Director of Product Marketing for Data Centers at Ecolab, to break down the CoolIT acquisition.

Walker discusses how Ecolab is pairing decades of industrial fluid management with CoolIT's cold plates, CDUs, and manifolds to solve critical operational bottlenecks. Learn why fluid health and monitoring matter during commissioning, how joint R&D at CoolIT's 6MW Calgary facility aims to extend single-phase cooling limits for extreme densities, and how integrated hardware and chemistry simplify lifecycle operations for hyperscalers and multi-tenant colocation operators.

Here's an overview of the conversation:

Building hyperscale data centers at the speed of AI comes with a massive challenge: taking care of the thousands of tradespeople on the front lines of construction sites. As project schedules compress and job sites push into remote locations, how do industry leaders build a culture that keeps workers safe, healthy, and genuinely supported?

In this episode of Data Center Richness podcast, we sit down with Trey Dean, Senior Vice President of Global EHS at Vantage Data Centers. Trey shares how Vantage is priotiizing site welfare, tracking workforce mental health with actionable data, and using AI and robotics to remove workers from high-risk duties., like moving giant racks

There's a big question at the heart of today's tech headlines: Is there an AI bubble? I sat down with someone who's been building data centers since 1997, and I found his answer really insightful.

That's Ron Vokoun. He's had 37 years in construction, most of it in digital infrastructure - fiber networks in the '90s, the first Qwest data centers, a stretch dedicated to prefab and modular builds, and now cooling as the Senior VIce President of Data Center Cooling at SVL Inc.

Ron has also become one of the most trusted voices curating data center news, first on LinkedIn, now with his Mission Critical Connections newsletter on Substack.

In this conversation, we get into why he thinks prefab is more important than ever due to the labor shortage in construction, how rack densities have blown past anything we saw coming, and his interesting answer on whether this AI buildout is a bubble, and what's actually keeping it in check.

Here's an overview of the discussion between Data Center Richness host Rich Miller and Ron Vokoun:

Demand for data center space is hitting all-time records. That is creating a major boom in data center construction, including more projects and larger campuses.

How does the industry keep track of all this construction? For more than 1,000 data center projects, the answer is OpenSpace, a technology company that provides visual intelligence on construction job sites. Its platform uses 360-degree cameras, smartphones and drones to create a digital record of the project that can be updated in real time.

OpenSpace packages this "reality capture" visual data in apps that offer a remote overview of the project, giving owners, general contractors, and subcontractors a shared visual record of every corner of these massive sites, updated continuously as work progresses.

OpenSpace CEO Jeevan Kalanithi joins us for a fascinating discussion about his company's platform and the role of technology in construction.

Inside the Future of Data Center Construction

Demand for data center capacity has never been higher. But building a data center is a complex undertaking, involving global supply chains and local contractors. As the industry seeks to build super-sized data center campuses, there are reports that a growing number of projects are falling behind schedule.

So what's the state of data center construction? To find out, we speak with Doug Mouton, who for many years worked with construction teams building data centers for Microsoft and Meta. Doug and host Rich Miller discuss the complexities of building at AI scale, and the supply chain and staffing challenges faced by large campus projects.

Doug is particularly focused on worker safety on job sites. Although data center construction teams have reduced the number of safety incidents, there is more work to do, especially on mental health and wellness for a workforce facing constant pressure on delivery schedules.

Doug is also deeply connected as an advisor and board member in the sector, and shares his takes on capital, the risks of geography and silicon, how inference may guide where projects get built, and how power influences the entire market.

Here's an overview of our discussion:

00:00 - Data Center Construction in the Spotlight

02:30 - Doug Mouton's Data Center Journey

06:40 - Data Center Delivery at AI Scale

10:24 - Data Center Safety: Stats and Solutions

Can electric vehicles, solar panels and smart thermostats in homes help free up more grid power for data centers? This concept that has been turning in recent months as the data center power crunch has become more challenging.

The concept known as a virtual power plant or VPP. It's a collection of small energy sources that are brought together to create a large energy asset, which can be managed to help support the power grid in moments of high usage. The owners of homes and vehicles get paid for the energy they share back to the grid.

Our guest today is Elisa Wood, an expert in distributed energy who can help us understand virtual power plants, and how they work. Elisa has been covering the energy sector for many years. She's the founder of Energy Changemakers, where she reports on the future of distributed energy.

I asked Elisa to join us because in recent months we've seen a growing push to tap unutilized energy that exists on power grids. It turned out to be a timely conversation. Literally while we were taping our podcast, Google announced a groundbreaking deal with VPP provider Voltus Energy, which marks the first time that a data center operator has worked with a VPP provider.

Their agreement is structured as a "Bring Your Own Capacity" deal, which will unlock 100 megawatts of new capacity on the PJM Interconnection, which serves 67 million customers in the Eastern half of the country. The location is notable because the PJM grid is facing capacity constraints, as well as a huge influx of data center projects.

Given the importance of the deal between Google and Voltus, Elisa rejoined me to share her take on the landmark deal and its significance. In today's episode you'll hear parts of both our conversations, which we've edited together to provide a solid understanding of virtual power plants and why they matter.
