ZTE urges industry to rethink energy efficiency

ZTE Corporation, a Chinese multinational telecommunications equipment and systems company, showcased its AI-embedded solution for data centre infrastructure at Data Centre World Frankfurt 2025. As artificial intelligence becomes deeply integrated into every layer of enterprise and cloud computing, the foundation of digital infrastructure is undergoing a fundamental transformation. Speaking at the event, Hans Neff, Senior Director of the CTO Group at ZTE, delivered a keynote address that challenged traditional efficiency metrics and static data centre models. He emphasised that in an AI-driven future, conventional benchmarks such as Power Usage Effectiveness (PUE) are "no longer sufficient" to measure the performance and adaptability of modern data centres. In his address, Hans highlighted the paradox facing today's data centres: at the very moment when sustainability has become a strategic priority, AI is driving up compute intensity and energy demand at an unprecedented scale. He believes traditional benchmarks, originally designed for static, legacy systems, are no longer capable of capturing the complexity and dynamism of AI-driven workloads. "AI workloads are fundamentally different," says Hans. "They're denser, hotter, and more variable. To stay ahead, we can’t keep optimising for a world that no longer exists." ZTE says its approach, drawn from global deployments and internal R&D, envisions energy efficiency not as a fixed target, but as an evolving system. The company states that it is engineering data centres that sense, predict, and respond to changing computational demands in real time. In his keynote address, Hans also called on the industry to adopt more holistic metrics that better reflect the realities of modern data environments. He proposed a new composite framework that evaluates energy use not only by its efficiency, but also by its effectiveness in supporting intelligent operations, resiliency, and sustainability. "PUE is no longer enough," argues Hans. "We need smarter metrics that account for how power is used — not just how much." For more from ZTE, click here.

Shell launches Direct Liquid Cooling fluid

Shell, a British-Dutch multinational oil and gas company, is turning down the heat and turning up the performance in data centres with the launch of Shell DLC Fluid S3 — a Direct Liquid Cooling (DLC) fluid designed to meet the demands of high-performance computing and artificial intelligence (AI). This propylene glycol-based fluid aims to complement Shell’s existing cooling fluid portfolio and involvement in the data centre liquid cooling market. As data centers grow more powerful, traditional air-cooling struggles to keep up with the increasing heat generated by high-performance computing and AI. DLC fluids tackle this heat by targeting high heat load components to ensure densely packed server racks can continue to operate at optimal temperatures. By directly cooling high-performance components like Central Processing Units (CPUs) and Graphics Processing Units (GPUs), DLC fluids can improve Power Usage Effectiveness (PUE) by up to 27% (in comparison with the PUE of air-cooling) and reduce the need for energy-consuming air conditioning. Shell DLC Fluid S3 also meets the Open Compute Project (OCP) PG25 coolant specifications, including standards for material compatibility. Some features of the Shell DLC Fluid S3 include: · Long-term corrosion protection for all DLC cooling systems, including aluminium, brass, cast iron, steel, solder, and copper. · Heat transfer performance: Particularly, according to Shell, for high-surface-area copper-based heat sinks. · Compatible with a range of materials including metals and metal alloys, elastomers, plastics, and other wetted materials as per OCP guidelines. Its 2-ethylhexyl acrylate-, borate- and silicate-free formulation intends to provide improved metal and rubber compatibilities over competitive formulations. · Extended fluid life: Expected life of 6+ years, potentially four better than conventional inorganic acid technology (IAT) based fluids. · Leak detection: Dyed fluorescent green to help identify in-service leakage. · Freeze protection: Used in servers and electronic components to provide freeze protection down to sub-zero temperatures (−10°C/14°F) and help prevent corrosion. “With Shell DLC Fluid S3, Shell now offers both direct-to-chip and full immersion cooling solutions, and we’re not just keeping data centres cool in the age of AI — we’re powering the future of digital infrastructure,” says Aysun Akik, VP New Business Development and Global Key Accounts, Shell Lubricants. “We are continuing our commitment to innovation that delivers on performance, sustainability, and reliability to support our customers’ goals.” Aysun continues, “Our growing range of advanced liquid cooling solutions is designed to meet the diverse needs of modern data centres both today and tomorrow – and are backed by the strength of Shell’s global footprint, supply chain, and five technology development hubs around the globe.” For more from Shell, click here.

Optical cable removes barriers to delivering 800G

A new proposal for long-haul optical network cables aims to ‘break through the glass ceiling’ of data transmission limits to ensure the ever-growing demands of data centres can be supplied. A new whitepaper from fibre cable experts Acome Group and Sumitomo Electric Industries says that existing optical fibre cables will only be able to meet the long-term transmission capacity needs of European data centres at a significantly higher cost and degraded environmental footprint. Conventional G.652.D optical fibres struggle to transmit data rates at and above 800 Gb/s over distances further than a few hundred kilometres. Over longer distances, such as between two data centres, signal regeneration or additional optical amplification is needed which adds complexity and costs for network owners. “With AI, cloud services, and the growth of hyperscale data centres dramatically increasing demand for bandwidth, telecom infrastructure must evolve to support high-capacity, long-distance transmission,” comments Xavier Renard, Telecom Marketing Director at ACOME. “It’s also crucial that we consider the longevity of the network. A network is not a static asset. It’s constantly evolving, so it’s essential that the fibre used is correctly selected to support future bandwidth over decades of use.” Acome and Sumitomo Electric have developed a new hybrid solution that aims to allow network operators to deploy a single, universal cable that supports both current and future network needs. Upgrading to 800G and above requires fewer repeaters to amplify the optical signals and can also avoid the need for signal regeneration. Their solution combines two existing fibre grades to provide a cable solution that should enable longer transmission distances, higher data rates per wavelength, and reduced infrastructure requirements – all of which are key enablers of energy-efficient, scalable, and future-proof optical transport networks. “PureAdvance fibres, compliant with ITU-T G.654.E, are contributing to evolve long-term network and transmission technologies. For example, combining G.654.E with G.652.D can maximise flexibility and futureproof the network,” adds Fumiyoshi Ohkubo, General Manager, Market Development & Engineering Department of Optical Fiber & Cable Division at Sumitomo Electric. This hybrid approach intends to create pathways for future upgrades to high-capacity, using coherent transmission, and enable a smoother migration to next-generation network architectures without needing full infrastructure overhauls.
