For this installment of the Data Center Frontier Show podcast, we bring you the first episode in a new series with our friends from the Nomad Futurist Foundation.

Nomad Futurist is a 501(c)(3) non-profit organization established, per the group's mission statement, "to demystify the world of digital infrastructure and the related technologies that impact every aspect of our daily lives." Committed to educating youth in underprivileged communities, promoting diversity and inclusion, and opening up opportunities for growth and new career paths, the group says its "primary focus is to empower and inspire younger generations through exposure to the underlying technologies that power our digital world."

Nomad Futurist is known for appointing individuals throughout the data center industry to its ranks of Ambassadors and Advisors, who work to promote the organization's ethos and goals in their professional spheres. The organization's members are a pervasive presence in the data center sector, to be found in attendance and presenting at most industry events in the U.S. and abroad.

The purpose of the Data Center Frontier/Nomad Futurist: Field Report series -- aka "Nomads at the Frontier" -- is therefore to gather recurring industry insight, expertise and commentary from Nomad Futurist leaders and ambassadors, firsthand and in the field, as they participate in these events.

For the first installment of Nomads at the Frontier, Data Center Frontier's Editor in Chief Matt Vincent called into Las Vegas during the debut of Yotta, an event conceived and brought forth by Data Center Dynamics aimed at unifying leaders and stakeholders in digital infrastructure industry at large.

For this interview, DCF spoke with Nomad Futurist Advisors Jodie Lin, Customer Advocate and CSR with data center infrastructure company Mirapath, Inc., and Illissa Miller, CEO of iMiller Public Relations, a firm focused on the digital infrastructure industry, for their reflections and impressions from the environs of Yotta 2024. To begin, we asked Lin and Miller for their top takeaways from the show regarding the confluence between the larger world of digital infrastructure and data centers.

Next, given how attuned data centers are to the AI technology shift, we asked Nomads Lin and Miller for their perceptions of the level of preparation within rest of the digital infrastructure space, as heard from at Yotta, for facing up to AI's demands and opportunities. DCF also wondered whether, based on impressions received from Yotta, the data center industry’s obsessions with power, cooling, sustainability, and managing exponential growth in wake of AI seem to be shared equally by the larger world of digital infrastructure.

Finally, owing to certain breakthroughs in the areas of regulation, funding, and planned deployment, this year has felt like a tipping point in terms of optimism for advanced nuclear energy, especially in the US data center industry. As such, we asked our Nomads to gauge whether this anticipation for "new nuclear" energy was as palpable in the larger world of digital infrastructure as encountered at Yotta?

Rehlko, formerly Kohler Energy, is setting a new standard in the data center industry by offering the first generator in the data center industry with an Environmental Product Declaration (EPD). The company recently released a brand new EPD in the form of a PEP ecopassport® that provides transparent, third-party verified insights into the KD Series™ generator’s environmental impact across its lifecycle. Here’s a link to the report that details how Rehlko is committed to transparently communicating its product's lifecycle footprint and how the process is accelerating data centers' efforts to measure Scope 3 emissions and work toward net-zero ambitions.

For this episode of the Data Center Frontier Show podcast, we sat down with liquid cooling data center partners Park Place Technologies and ZutaCore. During the podcast, DCF Editor in Chief Matt Vincent spoke with Chris Carreiro, Chief Technology Officer for Park Place Technologies, and Manfreid Chua, Vice President-Business Development, AI & Sustainability for ZutaCore, about how the companies' partnership is enhancing liquid cooling technology prospects for sustainable AI computing.

In September, Park Place announced the expansion of its portfolio of IT infrastructure services to include the two major liquid cooling formats for data centers, i.e immersion liquid cooling and direct-to-chip cooling. ZutaCore is a key developer and supplier of direct-to-chip, waterless liquid cooling technology which formally supports NVIDIA's GPUs.

Direct-to-chip advanced liquid cooling technologies apply coolant directly to the server components that generate the most heat, including CPUs and GPUs. And Park Place notes that immersion cooling empowers data center operators to do more with less: less space and less energy. Using liquid cooling methods, the company contends that businesses can increase their PUE by up to 18 times, and rack density by up to 10 times. Ultimately, this level of efficiency can lead to power savings of up to 50%, which in turn leads to lower operational costs.

Park Place also notes how, from an environmental perspective, liquid cooling is significantly more efficient than traditional air cooling. The company reckons that, at present, air cooling technology only captures 30% of the heat generated by the servers, compared to the 100% captured by immersion cooling, resulting in lower carbon emissions for businesses that opt for immersion cooling methods.

Park Place prides itself on providing a single-vendor outlet for the whole liquid cooling technology adoption process, from procuring the hardware, conversion of the servers for liquid cooling, to installation, maintenance, monitoring and management of the hardware and the cooling technology.

“Our turn-key liquid cooling offerings have the potential to have a significant impact on our customers’ costs and carbon emissions, two of the key issues they face today,” said Carreiro. “Park Place Technologies is ideally positioned to help organizations cut their data center operations costs, giving them the opportunity to re-invest in driving innovation across their businesses."

In the course of our talk, Carreiro highlighted the challenges of data centers' AI sustainability conundrum, and the corresponding benefits of Park Place's warranties. For his part, ZutaCore's Manfreid Chua delved into the industry's shift from air to liquid cooling due to the demands of generative AI, and the advantages of his company partnering with Park Place for optimizing the energy efficiency footprint of data centers.

Additionally, Chua shared insights regarding the economic value of NVIDIA's AI accelerators, and the finer points of the race to sustainability and net zero for large-scale AI data centers. Chua talked about talk about how resources like land, energy, and water all become possible limiting factors for AI factories at scale, and how liquid cooling can help alleviate such limitations.

Prometheus Hyperscale is the new corporate entity formed this month which expands upon the footprint and the promise of the Wyoming Hyperscale White Box project, first reported on by DCF in 2022.

For this episode of the Data Center Frontier Show podcast, we spoke with Trenton Thornock, founder of Wyoming Hyperscale, who has been appointed as Chief Executive Officer of Prometheus Hyperscale; Trevor Neilson, a seasoned climate-tech CEO and energy transition investor, who joins as the company's President; and John Gross, President of J.M. Gross Engineering, who is handling the project's liquid cooling infrastructure.

The Wyoming Hyperscale White Box data center has been under construction since 2022 on 58 acres of land near Aspen Mountain Evanston, Wyoming, and represents a blueprint for creating super-efficient data centers with low impact on the environment and benefits for the local community. In the companies' transition, Wyoming Hyperscale has merged with Prometheus Hyperscale and been expanded from a 120 MW project to plans for a data center campus with 1 GW of IT capacity.

The data center is being built on land owned by Thornock's family, which has been involved in ranching for 6 generations. The location benefits from ready access to renewable energy from nearby wind and solar farms. Wyoming Hyperscale has a contract with Rocky Mountain Power for 120 megawatts of power and a 138 kV substation, which is fed by the same switchgear as the renewable energy generation sites. The site sits on a major east-west fiber highway that tracks the 41st parallel, along which data center hubs have emerged in places like Ohio, Iowa, Nebraska and Utah. The Union-Pacific Railroad line, which provides key right-of-ways for fiber deployment, runs through nearby Aspen Mountain.

The Evanston project underscores Prometheus Hyperscale’s commitment to sustainability and innovation. By integrating 100% renewable energy and advanced liquid cooling technology combined with heat reuse, the Evanston facility promises to be one of the most efficient and environmentally friendly data centers in the world. Importantly, less than 10% of the project’s power development plan is grid dependent (120 MW of 1,220MW or 9.84%).

The first facilities yielded by Phase 1 of the Evanston project are expected to come online within the next 18 months. Prometheus Hyperscale has also revealed plans to construct four other data centers across Arizona and Colorado. And as previously reported by DCF, this May saw the announcement of a 20-year power purchase agreement (PPA) by fission-based nuclear small modular reactor (SMR) specialist Oklo to deliver 100 MW of power to Prometheus, using Oklo's Aurora Powerhouse reactors for power generation.

"Our partnership with Oklo not only provides us with a reliable, clean energy source but also positions us as a leader in sustainable data center operations," said Thornock. "Sam Altman’s and Jacob Dewitte’s vision for a sustainable future through advanced energy solutions aligns perfectly with our mission at Prometheus Hyperscale."

During the podcast, Thornock discussed the evolution of the Wyoming hyperscale project with Prometheus, highlighting its growth to a 1 GW prospect since the groundbreaking of the Evanston County project in 2022. For his part, Trevor Nielsen emphasized increasing demand for Prometheus driven by advancements in computing power and the importance of sustainability in the energy transition.

Our conversation also covered the company's partnership with Oklo, focusing on the streamlined permitting process for small modular reactors in Wyoming and the strategic use of resources for data center energy generation.

Sustainability is a critical factor in data center design. The topic encompasses a series of design trade offs including: reliability, site selection, water usage, operating parameters, construction materials and cooling efficiencies. Due to a couple of key paradigm shifts in the industry, today’s data center owners and operators are looking to meet their cooling demands with air cooled solutions. All this needs to be done in conjunction with optimizing energy efficiency leading to a significant change in HVAC system products and design.

In this conversation, Jeffrey Jerwers can discuss the trends driving the need for water conservation and associated equipment impact. He will detail the types of economizers available for mechanical cooling systems, application by climate zone and their associated design tradeoffs.
