Thermo-Economic Potential of Carnot Batteries for the Waste Heat Recovery of Liquid-Cooled Data Centers with Different Combinations of Heat Pumps and Organic Rankine Cycles

When evaluating turning liquid-cooled data-centre waste heat into electricity, weigh RTE (76-83%) against specific cost (767-1125 USD/kWh); higher RTE can come with a cost increase.

  • System cost is about 767-796 USD/kWh depending on the cycle combination.

To Defer or To Shift? The Role of AI Data Center Flexibility on Grid Interconnection

In large-load interconnection negotiation, present AI load flexibility (a deferral window of up to about 3 hours) as a lever for interconnection capacity and timing; returns diminish beyond 3 hours.

  • In the IEEE 14-bus study, data centres on buses connected to congested lines benefit most from geographic load shifting.

Toxicological and environmental evaluation of the two-phase immersion cooling fluid HFO-153-10mczz-E

When selecting a two-phase immersion fluid, add toxicology and occupational exposure limit (here WEEL 200 ppm) to the specification alongside boiling point (40-60 °C), dielectric strength, non-flammability and material compatibility.

  • HFO-153-10mczz-E meets the OECD structural definition of a PFAS and falls in the short-chain PFAS category.

Transforming Future Data Center Operations and Management via Physical AI

For fast what-if analysis consider a CFD-trained surrogate (inference about 0.01 s), but state that the surrogate is only as accurate as the CFD it was trained on and is not validated against measurements.

  • The CapEx of building a data centre with 100k B200 GPUs is 4.5 to 5 billion US dollars and annual electricity OpEx can reach 400 million.

Two-Stage Power Delivery Architecture Using Hybrid Converters for Data Centers and Telecommunication Systems

In rack power-chain efficiency calculations, treat the number of stages and each stage's efficiency as separate inputs, and show the benefit of fewer stages at load points (low and high current).

  • End to end, direct conversion from about 110 VAC to 1 VDC peaked at 84.1% efficiency at 50 A and fell to 73.5% at 160 A.

Using life cycle assessment to drive innovation for sustainable cool clouds

Add a cooling-technology comparison calculator that computes annual energy as IT MW x load factor x PUE x 8760 and applies the paper's Table 3 deltas (PUE -3%/-6%, IT capacity +3%/+6%) and Table 4 savings ranges as tagged defaults.

  • Switching to 100% renewable electricity cut GHG by 85-90%, energy demand by 6-7% and blue water by 55-85%; server embodied carbon became more significant.

Valve Regulated Lead Acid Battery Evaluation under Peak Shaving and Frequency Regulation Duty Cycles

When considering VRLA UPS strings for grid services, account for frequency regulation (especially in a low SOC window) degrading batteries much faster than peak shaving, with capacity loss tracking internal resistance rise.

  • Test modules: six-cell C&D SHC 12-200FT lead-carbon AGM VRLA, 172 Ah at the C10 rate to 1.8 V/cell at 25 °C, 60 kg.

Wide-Area Power System Oscillations from Large-Scale AI Workloads

Model AI data-centre load as a persistent periodic forcing (0.3-1.5 Hz band, about 20% of peak fluctuating) rather than a ramp, and add oscillation analysis to the grid-interconnection study.

  • The fine-tuning model uses a dominant frequency U(0.3, 0.7) Hz and compute fraction 0.7-0.9.

xPUE: Extending Power Usage Effectiveness Metrics for Cloud Infrastructures

Do not present facility PUE as the whole efficiency story: add an optional server-overhead factor (sPUE) to the energy model and show an 'effective PUE' = PUE x sPUE next to PUE.

  • Idle servers gave sPUE > 4; on a Dell R640 under rising CPU load the average sPUE was 3.1 and the lowest 2.7.

Zero-Carbon Development in Data Centers Using Waste Heat Recovery Technology: A Systematic Review

In waste-heat use, first match technology to source temperature (heat pump 20-55 °C, absorption cooling 30-85 °C) and think of electricity, heat, cooling and storage together rather than a single technology.

  • Heat pumps for WHR are listed for source temperatures of 20-55 °C and absorption refrigeration for 30-85 °C.

Cooling the Data Center: Design of a Mechanical Controls Owner Project Requirements (OPR) Template

Use the eight-section outline as the skeleton for the controls part of an Owner's Project Requirements before the Basis of Design starts.

  • HPC system refresh cycles can be about 3 years, so mechanical cooling upgrades may follow a similar cycle.
