Europe Data Center Colocation Market Snapshot

Europe's Data Center Investment Is Shifting Beyond Established Hubs

The UK and Germany captured 19.59% and 13.74% of European data center investment in 2025, keeping a significant share of capital concentrated in Europe's two largest markets.

The entry of Ada Infrastructure, Compass Datacenters, DAMAC Digital, DayOne, and Prime Data Centers is widening the European colocation operator base and expanding the pipeline of new data center developments.

Power, land, and sustainability restrictions in Amsterdam are adding new constraints to data center development, increasing the importance of alternative locations for future capacity.

Italy's development pipeline includes approximately USD 8.13 billion across two major announced investments, the Trino site redevelopment and three EdgeConneX campuses in Lombardy, signaling a significant increase in the scale of planned capacity.

The planned USD 2 billion AI-ready data center near Helsinki highlights the Nordics' growing role in accommodating power-intensive AI infrastructure, supported by access to renewable energy.

Higher Rack Power Densities Shift European Data Centers Toward Liquid Cooling

In Europe, data centers are increasingly adopting liquid cooling technologies as traditional air-based cooling systems face growing pressure from high-performance computing (HPC), AI workloads, and rising rack power densities. To improve thermal management and energy efficiency in these high-density environments, operators are turning to two key approaches: direct-to-chip liquid cooling, which circulates coolant directly to heat-generating components such as CPUs and GPUs, and immersion cooling, which submerges computing components in a non-conductive liquid to remove heat efficiently. Growing heat loads from AI and HPC deployments are therefore expected to increase investment in advanced liquid cooling technologies across European data centers during the forecast period.

AI Adoption Expands the Need for AI-Ready Data Center Infrastructure Across Europe

AI adoption is expanding across Europe as businesses, governments, and research institutions increase investment in AI technologies and supporting digital infrastructure. The Netherlands, which ranked fourth globally in the Government AI Readiness Index 2025, has 95% of organizations running AI programs, while Ireland's updated National AI Strategy includes actions related to digital infrastructure and data center development. The growing deployment of AI and high-performance computing workloads is increasing the need for computing capacity, power infrastructure, and high-density data center environments, strengthening the investment outlook for AI-ready data center infrastructure across Europe.
