Low-carbon hydrogen: not yet viable as primary power source

The cost of low-carbon green hydrogen will be prohibitive for primary power for many years – but some operators may adopt high-carbon (polluting) gray hydrogen ahead of transitioning to green hydrogen

AI and cooling: methods and capacities

AI infrastructure increases rack power, requiring operators to upgrade IT cooling. While some (typically with rack power up to 50 kW) rely on close-coupled air cooling, others with more demanding AI workloads are adopting hybrid air and DLC.

 
Uptime’s predictions for 2025: an overview

This summary of the 2025 predictions highlights the growing concerns and opportunities around AI for data centers.

AI embraces liquid cooling, but enterprise IT is slow to follow

Power and cooling requirements for generative AI training are upending data center design and accelerating liquid cooling adoption. Mainstream business IT will not follow until resiliency and operational concerns are addressed.

 
Sweat dedicated GPU clusters to beat cloud on cost

Dedicated GPU infrastructure can beat the public cloud on cost. Companies considering purchasing an AI cluster need to consider utilization as the key variable in their calculations.

 
Five data center predictions for 2025

Uptime Intelligence looks beyond the more obvious trends of 2025 and identifies examines some of the latest developments and challenges shaping the data center industry.

Data center resource use will raise deep questions — and opposition

As AI supercharges the growth in data center energy demands, new developments are likely to be increasingly politicized. Central governments may support their expansion, but opposition from local authorities and environmentalists will grow.

AI to trigger radical overhaul of data center electrification

Supersized generative AI models are placing onerous demands on both IT and facilities infrastructure. The challenge for next-generation AI infrastructure will be power, forcing operators to explore new electrification architectures.

16 Dec 2024
Grid demand will require active participation from data centers

Power grids are under stress, struggling to meet future demand and increasingly prone to outages. More utilities will expect data centers to contribute power — and be more flexible in their use of power.

REPLAY | Uptime Intelligence Client Webinar: Cooling the AI heat wave

In this inaugural Uptime Intelligence client webinar, Uptime experts discuss and answer questions on cooling technologies and strategies to address AI workloads. Uptime Intelligence client webinars are only available for Uptime Intelligence subscribe...

Immersion cooling evolves in response to IT power density

Generative AI is not only accelerating the adoption of liquid cooling but also its technical evolution. Partly due to runaway silicon thermal power levels, this has led to a convergence in technical development across vendors.

Hydrogen fuel cells: a niche option for standby power

Hydrogen from renewable sources is in short supply. While future plentiful supplies are planned, currently only a very small number of data centers are using hydrogen for standby power.

Why didn’t data center operators notice the 2024 solar storms?

Powerful solar storms have already brought warnings of disruption to electricity grids and their customers twice in 2024 — and the Sun’s activity has yet to peak. Why do data centers and power utilities appear to have escaped unscathed?

 
Why regulation on temperature can be counterproductive

Raising supply air temperature is drawing interest from data center providers and regulators in some countries. While saving energy, it may also reduce resiliency. This report quantifies energy impacts to clarify when it can be beneficial.

Should data centers sell their heat?

Historically, data center waste heat recovery has been promoted with a focus on the benefits for the heat off-taker. And yet, the overall winner in most situations is the data center operator — even if they are not paid for heat.
