800 VDC rack power
Emerging · UPS & Power Distribution, Switchgear & Transformers
800 VDC is a proposed power architecture for AI racks approaching 1 MW, converting AC to DC centrally and distributing 800 V DC to racks to cut copper, conversion stages and losses. NVIDIA has published the architecture and suppliers including ABB, Eaton and Schneider Electric have announced products, but it is not yet a shipping mainstream design.

Backup power and energy storage
Established · UPS & Power Distribution, Gensets & On-site Power, BESS & Energy Storage
Backup power keeps IT running through grid faults: static UPS with batteries, rotary or flywheel UPS, diesel or gas generator sets, and increasingly battery energy storage that can also support the grid. Ratings mix kW, kVA and MWh, so power and energy must never be added together.

Brownfield liquid cooling upgrades
Established · CDUs & Direct Liquid Cooling, Chillers & Precision Cooling
Brownfield upgrades add liquid cooling to existing air cooled halls. Options run from rear-door heat exchangers and liquid-to-air CDUs that need no new facility water, to tapping chilled water with liquid-to-liquid CDUs, to full new warm water loops. Structural, power and water constraints decide what is feasible.

Coolant distribution units (CDUs)
Established · CDUs & Direct Liquid Cooling
A CDU is the pump, heat exchanger and control skid that separates the facility water loop from the clean technology cooling system (TCS) loop feeding cold plates or immersion tanks. Ratings depend on approach temperature, flow and fluid, so capacities are only comparable at stated conditions.

Data centre heat reuse
mixed · Heat Rejection
Heat reuse exports data centre heat to district heating, buildings or industry, usually via plate heat exchangers and often heat pumps. Liquid cooling raises the heat grade. In Germany EnEfG section 11 sets energy reuse factor requirements for new data centres, so heat reuse is becoming a design and permitting question.

Data centre power distribution
Established · Switchgear & Transformers, UPS & Power Distribution
Power distribution covers the chain from the utility or on-site connection through MV switchgear and transformers to LV switchboards, UPS, busway and rack PDUs. AI loads push higher currents and faster build schedules, so lead times for transformers and switchgear and factory capacity are central sourcing risks.

Direct liquid cooling (direct-to-chip)
Established · CDUs & Direct Liquid Cooling
Direct liquid cooling pumps coolant through cold plates mounted on CPUs, GPUs and other hot components, removing most server heat into liquid. It is the main route to rack densities beyond what air can handle, and it comes in single-phase water or glycol and two-phase refrigerant variants.

Heat rejection
Established · Heat Rejection, Chillers & Precision Cooling
Heat rejection is the plant that finally dumps data centre heat to outdoor air or water: dry coolers, adiabatic coolers, cooling towers, evaporative systems and chillers. Liquid cooling with warm water lets more hours run on dry or adiabatic coolers without compressors, trading footprint and water use against energy.

Immersion cooling
mixed · Immersion Cooling
Immersion cooling submerges servers in a dielectric fluid, either in open tanks (single-phase or two-phase) or in sealed chassis (precision immersion). It removes heat from all components, allows warm water heat rejection and can eliminate server fans, but needs adapted hardware, fluid management and service procedures.

Warm-water cooling loops
Established · CDUs & Direct Liquid Cooling, Heat Rejection
Warm-water loops run facility water at 30 to 45 °C or more so that heat can be rejected with dry coolers for most of the year and reused more easily. ASHRAE TC 9.9 defines W classes by maximum facility water supply temperature, from W17 up to W45 and W+ above 45 °C.
