Italy's Superconducting Leap: Powering AI with Zero Energy Loss

ROME, Italy – July 22, 2026 – The engine of the modern digital world—artificial intelligence, cloud computing, and big data—runs on an increasingly unsustainable fuel: electricity. As our demand for data services explodes, the sprawling data centers that house this digital life are consuming power at an alarming rate, posing a significant challenge to global energy grids and climate goals. Now, an ambitious Italian initiative aims to tackle this crisis head-on, not by limiting our digital appetite, but by fundamentally re-architecting how power flows.

The SURE project, a collaboration between industrial specialist ASG Superconductors and the National Institute of Nuclear Physics (INFN), has been launched to develop a zero-loss superconducting cable specifically for next-generation data centers. This initiative represents a strategic move to reconcile the exponential growth of digital infrastructure with the urgent need for efficiency and sustainability.

The Unseen Crisis in the Cloud

Behind every AI-powered query and cloud-based application is a physical data center consuming vast amounts of energy. The global data center power market, valued at nearly $31 billion in 2026, is projected to surge past $51 billion by 2033, driven largely by the power-hungry processors required for AI workloads. This growth is straining the limits of conventional power infrastructure.

For decades, data centers have relied on copper or aluminum cables to deliver electricity. However, these materials have inherent electrical resistance, which causes a portion of the energy to be lost as heat. In a hyperscale data center, these resistive losses add up to a significant waste of power and create a secondary problem: managing the excess heat, which requires even more energy for cooling systems. Furthermore, transmitting higher power loads with traditional cables requires thicker, bulkier wiring, consuming valuable and expensive real estate within the facility.

"The current trajectory is simply not sustainable," noted one industry analyst. "We are approaching a physical and economic limit with copper. The industry is actively searching for a paradigm shift, and high-efficiency power transmission is at the top of the list."

A Superconducting 'Bridge' Material

The solution proposed by the SURE project lies in the remarkable physics of superconductivity—the ability of certain materials to conduct electricity with zero resistance when cooled below a critical temperature. This eliminates energy loss entirely. At the heart of the Italian project is magnesium diboride (MgB₂), a material discovered in 2001 that offers a unique blend of performance and practicality.

Superconductors are typically categorized as either Low-Temperature (LTS) or High-Temperature (HTS). LTS materials, like those used in large particle accelerators at CERN, require cooling to near absolute zero with expensive and energy-intensive liquid helium. HTS materials can operate at the warmer temperature of liquid nitrogen, but can be complex and costly to manufacture. MgB₂ acts as a 'bridge' between these two categories. It becomes superconducting at 39 Kelvin (-234°C) and can operate efficiently around 20 Kelvin (-253°C). This temperature, while still incredibly cold, is achievable using well-established industrial cryocoolers or liquid hydrogen, reducing cooling costs by more than ten times compared to deep-cryogenic LTS systems.

Crucially, the raw materials for MgB₂—magnesium and boron—are abundant and inexpensive, and the technology developed by ASG Superconductors in Italy does not rely on the rare earth elements often found in other advanced electronics. This combination of operational efficiency and material accessibility makes it a powerful contender for widespread commercial adoption.

From Particle Physics to Power Grids

The SURE (SUperconducting – REliability & Efficiency) project is more than just a research experiment; it is a focused, well-funded national strategy. Backed by a €5.8 million grant from the Italian Fund for Applied Sciences (FISA), the initiative leverages a potent public-private partnership. ASG Superconductors brings manufacturing prowess and deep expertise in MgB₂ wire, honed through its contributions to major scientific projects like the High-Luminosity upgrade for the Large Hadron Collider at CERN. INFN provides the fundamental scientific leadership and the real-world testbed.

Over the next five years, the project will culminate in the design, construction, and installation of a 50-meter prototype cable at the new data center at INFN's National Laboratories of Frascati. This demonstration line will be engineered to carry an impressive 1,500 amps at 400 volts, showcasing its capacity for high-power applications. The scientific activities and system integration will be coordinated by researchers from INFN's LASA laboratory in Milan and the Frascati labs, laying the groundwork for future superconducting power grids on a much larger scale.

Reshaping Digital Infrastructure

The implications of this technology extend far beyond energy savings. Because superconducting cables can carry immense electrical currents in a very small cross-section, they offer a dramatic reduction in physical footprint—up to ten times smaller than conventional copper cabling for the same power load. This compactness is a game-changer for data center design.

This space-saving quality could enable the construction of powerful data centers in dense urban areas where space is at a premium, bringing data processing closer to end-users and reducing latency for critical applications. The technology opens up new possibilities for retrofitting existing facilities or building on sites with significant infrastructure constraints.

Italy's SURE project enters a competitive but nascent field. Global technology giants like Microsoft are publicly investigating superconducting solutions to power their next generation of AI-focused data centers, and companies like Nexans and VEIR are already demonstrating similar technologies. The race is on to commercialize a solution that can meet the moment. By uniting its industrial and scientific expertise, Italy is making a bold play to become a key architect of a more efficient and sustainable digital world.
