Dominic Jainy, an infrastructure expert with a deep background in artificial intelligence and machine learning, offers a unique perspective on the €1 billion conversion of a former chemical facility in Flix, Catalonia, into a cutting-edge AI hub. This massive project signals a major strategic shift for Submer, as they transition from specialized cooling technology to full-stack infrastructure through their new Rubix Data Centers division. By revitalizing an industrial site that went silent in early 2023, the initiative aims to establish Spain as a premier leader in the European AI landscape. Our discussion explores the balance between preserving industrial heritage and meeting the extreme high-density power demands of the next generation of computing.
How does the conversion of a legacy industrial site like the Ercros plant into a billion-euro AI hub reflect the broader reindustrialization trends occurring across Europe?
This transformation represents a landmark moment where a €1 billion investment breathes new life into a location that effectively went silent in January 2023. By taking a former chemical factory in Flix and turning it into a high-tech data center, Submer is leveraging existing industrial heritage to build the foundation for a digital economy. The site will be developed in two distinct phases, with renders suggesting a layout of four data halls centered around a main facility to maximize efficiency. This evolution replaces the heavy odors and machinery of the chemical past with the quiet, high-voltage hum of servers, proving that dormant industrial zones can be repurposed into durable assets.
Submer is pivoting from specialized cooling to building full-stack data centers; what does this strategic move reveal about the current power requirements of AI infrastructure?
The pivot to launching Rubix Data Centers highlights a massive industry shift where companies must control the entire environment to successfully manage the heat and intensity of modern AI. By moving beyond hardware to offer integrated solutions, including their own AI cloud platform like InferX, they can better serve a single tenant with massive, uninterrupted compute needs. The scale of their ambition is evident in their claim to have 8GW of power available across vacant sites in the Americas, EMEA, and APAC regions. Controlling the full stack—from the land and power to the liquid cooling—is the only way to ensure the infrastructure can handle the staggering energy density that these workloads now require.
Beyond the technical specifications, what kind of long-term economic and social impact does a project of this magnitude have on a local community like Flix?
A project of this scale is a deep commitment to the local community that focuses on returning a defunct site to productive, long-term use. The investment is expected to create skilled local jobs, shifting the regional skillset from traditional chemical processing to advanced digital infrastructure management. By working closely with the Catalan administration and the regional minister of business and labor, the project ensures that the economic benefits of the €1.14 billion investment remain rooted in the local soil. It is an initiative designed to provide lasting value, turning what could have been a forgotten industrial relic into a vibrant center for regional innovation and employment.
The development is planned in two phases with a specific hall layout; why is this architectural and timeline strategy so critical for modern data hubs?
A phased approach is essential for managing the sheer complexity and the massive capital requirements associated with high-performance AI sites. By starting with a clear vision of four data halls surrounding a central building, the developers can ensure that the infrastructure scales in a way that remains stable and efficient. This strategy allows the team to secure power and build out the facility methodically, ensuring that every part of the 8GW global pipeline is utilized effectively. It creates a resilient environment where the technology can be updated in stages, keeping the facility at the absolute cutting edge of the industry for years to come.
What is your forecast for AI infrastructure in Spain?
I forecast that Spain will soon become the primary strategic hub for European AI infrastructure, specifically by repurposing its vast industrial landscapes for high-density computing. As we see with the Flix project, the trend is moving away from generic, multi-tenant facilities toward specialized, single-tenant sites that can handle the massive power needs of machine learning. The success of this €1 billion initiative will likely trigger a wave of similar reindustrialization projects across the EMEA region as countries compete for digital sovereignty. Ultimately, the ability to combine historic power availability with advanced cooling will make Spain an indispensable node in the global AI network.
