Late change reinstates some EU reporting rules

A last-minute revision to the European Commission’s plans to simplify regulations has brought some companies back under the scope for CSRD reporting.

Validating the use of high-density DLC

Data4 needed to test how to build and commission liquid-cooled high-capacity racks before offering them to customers. The operator used a proof-of-concept test to develop an industrialized version, which is now in commercial operation.

Emerging tech: enhanced geothermal systems

Enhanced geothermal systems use advanced drilling and hydrofracturing techniques to access geothermal energy in more locations. Some data centers may use enhanced geothermal energy for on-site, low-carbon power.

EU makes more cuts to environmental reporting

The European Parliament plans to simplify environmental reporting beyond what the Omnibus proposed in early 2025. Under the new reporting thresholds, only the largest 10% of companies would remain subject to CSDDD and CSRD requirements.

China: centralized rules for data center efficiency

China wants to expand its data center capacity, and to achieve net-zero emissions. To this end, the nation is regulating for efficiency and renewable energy, as well as harnessing centralized control, to balance growth with sustainability.

Emerging tech: superconductivity in the facility

Superconducting busbars could offer a solution for delivering power to high-density racks, eliminating resistive heating and removing the need to shift to medium voltage distribution equipment.

Why are operators collecting less sustainability data?

Fewer people in the industry are talking about sustainability. But why has the collection of data also declined, when such data is often required by reporting regimes?

Battery options fizzle as sodium-ion startup shuts

Sodium-ion batteries promised a third battery option to lead-acid and lithium-ion batteries. The closure of Natron Energy means operators will need to look elsewhere.

Emerging tech: low-carbon hydrogen

Operators looking for low-carbon power may be assessing low-carbon hydrogen for standby or primary power. Except for niche applications, the technology is a long way from practicality.

Emerging tech: superconductivity for power delivery

Superconductive power cables promise faster, cheaper and simpler connections for data center operators waiting for power. They could also simplify campuses and microgrids.

Power companies act to stop data center-induced blackouts

In Northern Virginia and Ireland, simultaneous responses by data centers to fluctuations on the grid have come close to causing a blackout. Transmission system operators are responding with new requirements on large demand loads.

Uptime Institute Global Data Center Survey 2025

The 15th edition of the Uptime Institute Global Data Center Survey highlights the experiences and strategies of data center owners and operators in the areas of resiliency, sustainability, efficiency, staffing, cloud and AI.

Enhanced geothermal: long-term clean power — for some

Underground hot rocks are emerging as a source of firm, low-carbon power for data centers, with new techniques expanding viable locations. Compared with nuclear, geothermal may be better positioned to support planned data center growth.
