01 Shift to Direct Current Infrastructure Driven by Energy Efficiency Demand The accelerating shift toward high-voltage direct current (HVDC) power architectures in AI-optimised data centres is driven by the need for greater energy efficiency, scalability, and alignment with green infrastructure goals. As AI, IoT, and edge computing workloads surge, operators are moving beyond traditional 48 V DC and AC systems to adopt HVDC designs that offer superior performance and higher power density. For example, in April 2024, tech giants including Microsoft, Meta, and Google began implementing high-voltage DC (400–800 V) systems in their AI data centres to enhance energy efficiency and support next-generation server densities. The Mount Diablo initiative, spearheaded under the Open Compute Project, promotes 400V DC distribution as a new standard, boosting power efficiency and enabling up to 1 MW per rack. This transition marks a critical inflexion point in data infrastructure design, reflecting a broader move toward DC-native systems that enable compact, scalable, and energy-optimised server environments.
01 Advanced Power Delivery Tech Enables Scalable Dc Servers The rapid emergence of new power delivery technologies, specifically voltage regulators and modular DC systems, is designed to optimise energy delivery from meter to chip. These innovations enable data centres, particularly AI-focused hyperscale facilities, to reduce conversion losses, simplify infrastructure, and improve thermal efficiency.By enabling end-to-end DC delivery, companies like Claros are shaping the future of server architecture, making DC-powered systems increasingly viable at scale.
01 Legacy Infrastructure and Interoperability Integrating high-voltage direct current (HVDC) infrastructure into legacy data centres originally designed for alternating current (AC) systems is a significant hurdle in market growth. Most existing server rooms and colocation facilities operate on standardised 208V or 480V AC power grids, and retrofitting them to accommodate 400–800V DC infrastructure involves significant redesigns, often requiring new cabling, power conversion systems, and safety protocols. These changes come with high capital expenditure and complex downtime planning, which many operators are reluctant to take on unless building new facilities from scratch.Moreover, many critical components, such as UPS (uninterruptible power supply) systems, PDUs (power distribution units), and cooling equipment, are still optimised for AC configurations. This limits plug-and-play compatibility and increases vendor lock-in, especially for hyperscalers and colocation providers aiming to transition incrementally.
01 Modular off-Grid Dc Systems Enable Rapid, Scalable Deployment Integrating modular, off-grid DC power solutions is designed to meet the rising demand for fast-tracked server deployments in areas facing grid limitations or long utility lead times. These systems eliminate dependency on traditional alternating current (AC) infrastructure and enable direct current (DC) server operations from alternative, on-site energy sources.By bypassing conventional grid dependencies and reducing conversion losses, such solutions unlock new deployment models for cloud providers and colocation firms under pressure to scale quickly.
