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.

Castrol launches new fluid management service

Castrol, a British multinational lubricants company owned by BP, known for its presence in the automotive industry, has launched a new fluid management service for data centre liquid cooling, addressing a critical gap as the industry transitions away from traditional air-cooling systems. Announced at the Datacloud Global Congress 2025 in Cannes, France, Castrol’s new service model aims to cover all four phases of the data centre operation lifecycle: system start-up, ongoing maintenance, break-fix support, and fluid disposal. The approach is designed to help remove operational barriers in the adoption of liquid cooling in data centres. "Data centre operators recognise the benefits of liquid cooling but need assurance around long-term fluid management," states Peter Huang, Global Vice President of Data Centre Thermal Management at Castrol. "Castrol has delivered fluid services for the automotive industry for decades – we're now bringing this proven expertise to data centres with a service model that supports optimal performance throughout the entire lifecycle.” The four-phase service includes:1. System start-up support with fluid installation, filtration, system flushing, and certificates of analysis.2. Ongoing maintenance, such as laboratory testing, dynamic monitoring, predictive maintenance, and smart dosing capabilities.3. ‘Break-fix’ service, including telephone assistance, virtual engineering support, on-site response, and spare fluid availability.4. Support with fluid collection and disposal. Castrol’s service launch comes at a time when the data centre industry faces mounting pressure to improve cooling efficiency. Recent industry research indicates that traditional air-cooling systems struggle to handle increased computing demands from AI and edge computing applications, with 74% of data centre experts believing immersion cooling is now essential to meet current power requirements. "Our aim with this new service model is to remove the operational and technical uncertainties that have slowed liquid cooling adoption," says Andrea Zunino, Global Offer Development Manager at Castrol. "Within liquid cooling systems, the fluid represents a single point of failure – degraded conditions can reduce cooling capacity and lead to equipment failure. We're going beyond just fluid supply to deliver structured support at every stage, giving data centre operators the confidence they need to embrace liquid cooling.” The new service model will be deployed globally through Castrol's partner network. All services will be delivered with third-party suppliers. The availability and rollout of certain services may vary by location and may be introduced at different times depending on regional factors. For more from Castrol, click here.

DE-CIX Dallas completes infrastructure upgrade

DE-CIX, an Internet Exchange (IX) operator, has announced the completion of a major infrastructure upgrade for DE-CIX Dallas – the largest data centre and carrier neutral IX in Texas. As part of the upgrade, 400 GE (Gigabit Ethernet) access ports are now generally available to customers, 100 GE access options have been expanded, and the platform has also been made 800 GE-ready, with the aim of helping the region prepare for the upcoming boom in internet peering services and latency-sensitive AI applications. One of the key changes of the upgrade is enhanced 100 GE access options for customers, now including 100 GE LR technology. While traditional 100 GE LR4 access requires four lasers for transmission, 100 GE LR requires only one laser and uses pulse amplitude modulation (PAM4) to ship data at 100 Gbit/s for a lower hardware cost, increasing efficiency and reducing the cost of optical hardware on the customer side. According to the Institute of Electrical and Electronics Engineers (IEEE) and the industry consortium 100G Lambda MSA, this could result in a transceiver cost reduction of more than 40%. Customer hand-off using 100 GE LR4 will continue to be available. The upgrade of DE-CIX Dallas using 400 GE wavelength technology should also increase the scalability of the platform. Additionally, the company has upgraded the US-wide backbone connecting Dallas to locations such as New York, Chicago, and Seattle, and has also connected the city to DE-CIX’s recently commissioned distributed IX in Mexico, with access points in Mexico City and Queretaro. News of the Dallas upgrade comes just weeks after the announcement that Nokia was selected by DE-CIX to upgrade New York’s largest IX backbone to 400 GE wavelength technology while offering 800 GE support. DE-CIX Internet and Cloud Exchanges in New York, Dallas, Chicago, Richmond, Houston, Phoenix, and the dedicated Cloud Exchange in Seattle, together with the Mexican IX, now form the largest carrier and data centre neutral interconnection ecosystem in the North America. If Texas was a country, it would be the eighth largest economy in the world, surpassing the likes of Brazil and Italy with a GDP of $2.4 trillion. According to analysts at Cushman and Wakefield, Dallas ranks sixth in global data centre market size, and the city was also recently ranked as the top business hub in America – in part due to its reputation for technological innovation. This upgrade to DE-CIX Dallas increases data capacity on the regional exchange and hopes to prime it for future growth. “By providing 100 GE LR and 400 GE access, introducing 400 GE wavelength technology in the backbone, and making the hub 800 GE-ready, we have now effectively future-proofed DE-CIX Dallas for the emerging needs of its customers,” comments Thomas King, CTO of DE-CIX. “Demand for large capacities and easy-to-consume interconnection services is set to increase dramatically in the coming years, driven by traffic from high-resolution video content, online gaming, and – of course – artificial intelligence. Customers require simplified solutions to ensure seamless integration of interconnection into their network management and infrastructure strategies to keep pace with this data traffic growth. This is why we not only increased capacity, but also further increased the resilience of the network and added an additional router in the Equinix DA11 facility.” DE-CIX Dallas is the operator’s second largest IX in North America, with over 140 networks connected. According to Ed d’Agostino, Vice President, DE-CIX North America, “Dallas is a vital transmission hub for our entire North American ecosystem, with a massive coverage potential spanning the South and Southwest regions of the USA and eastern Mexico. The investment in upgrading DE-CIX Dallas demonstrates our continuing commitment to this very important market and the expectation of substantial additional growth.” For more from DE-CIX, click here.

EUDCA’s research affirms critical importance of data centres

The European Data Centre Association (EUDCA), a trade body representing data centre operators, suppliers, and stakeholders across Europe, has announced the publication of its inaugural State of European Data Centres report, in collaboration with European National Trade Associations (NTAs). The new report marks an important step in documenting and recording the state of the industry, allowing greater ongoing analysis and insights, tracking progress and development, and reflecting a vibrant industry that while experiencing challenges, has potential to be at the heart of a digital Europe. Michael Winterson, Secretary General of the EUDCA, says, “Europe’s digital economies could not have been established without the backbone of data centres that provide digital sovereignty while contributing significantly to GDP. The State of European Data Centres 2025 provides a benchmark of this vital industry and a reference point for informed, data-driven decision-making as we continue building Europe’s digital future.” According to the report, the data centre industry contributes significantly to Europe’s socio-economic landscape. Colocation data centres alone were responsible for €30 billion in GDP in 2023, expected to reach €83.8 billion by 2030, with the creation of thousands of direct and indirect jobs. The market is expanding rapidly, driven by artificial intelligence (AI) and digital service growth, with demand outstripping supply and attracting billions of euros in investment. Major centres of activity include Frankfurt, London, Amsterdam, Paris, and Dublin (FLAPD), with intense activity in emerging hubs in the Nordics and Southern Europe. Additionally, new metropolitan hubs are emerging in and around cities such as Barcelona, Rome, and Athens. “A key implication from the report,” continues Michael, “is the need for data centres, as large energy consumers, to become flexible energy partners to grid providers.” Sustainability data shows that more than a quarter (28%) of operators have invested in on-site renewable energy generation capability, and 41% plan to do so. In support of these efforts, 28% are planning on installing battery energy storage systems (BESS) within the next two years. Currently, nearly a quarter (22%) of data centre operators provide grid stabilisation or energy trading capacity to energy grids, greatly facilitating further utilisation of renewable energy sources (RES). This will almost triple (59%) in the next two years. All of this means that data centre operators, through increased resilience and energy independence, can engage with grid operators to relieve stress on grids, while providing supports such as grid stabilisation services. The report finds the industry faces challenges related to power availability, sustainability, and regulatory compliance as new reporting obligations recently came into effect. More than a third (36%) said that regulatory compliance will be a challenge over the next three years. However, these challenges also present opportunities for innovation in energy efficiency, flexibility, and heat reuse. The sector's continued growth will necessitate ongoing investments in sustainability to minimise environmental impact. Another bright spot is improvement in water usage. Of those operators who reported water usage effectiveness (WUE), the average was 0.31 litre per kWh for 2023, well below the Climate Neutral Data Centre Pact (CNDCP) target of 0.4 l/kWh for water-stressed areas. The industry is also advancing technologies such as liquid cooling and heat reuse to improve efficiency and reduce its environmental footprint. Currently, half of operators have residual heat coupling capability, with a further 38% expected in two years. Already, three quarters of operators have energy or environmental management systems in place. The data centre industry also faces significant challenges, including power supply constraints, permitting delays, and a growing skills gap in technical fields. More than 75% of survey respondents consider access to power as the biggest challenge for the sector in the next three years, despite a willingness to invest in alternative solutions to access power. Energy costs are also a concern, as rising wholesale prices impact operators. The additional responsibility of regulatory compliance was also significant, with more than a third (36%) citing it as a major challenge in the near future. There are significant concerns that duplication and redundancy in reporting frameworks will deter compliance, reducing effectiveness and frustrating regulatory goals.

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.
