EUROPE DATA CENTER COLOCATION MARKET TRENDS

Rise in Adoption of Liquid Cooling Techniques

1. In Europe, data centers are increasingly adopting liquid cooling techniques as traditional air-based cooling techniques are increasingly strained by increasing high-performance computing (HPC), AI workloads, and increasing rack power densities.
2. Therefore, data center operators are shifting toward liquid cooling techniques as liquid cooling offers enhanced thermal management, energy efficiency, and support for modern computing workloads efficiently.
3. In November 2025, Vertiv announced that it has launched the CoolCenter Immersion system pod; this can support around 25 kW to 240 kW per system, and this is now available in Europe, the Middle East, and Africa (EMEA).

The Rise in AI Adoption

1. The Netherlands acquired the fourth rank globally in the Government AI Readiness Index 2025. The country leads Europe in AI adoption, with 95% of organizations running AI programs.
2. In September 2025, Carbon3.ai, the UK-based AI infrastructure firm, launched a sovereign AI platform in collaboration with Hewlett Packard Enterprise and other companies to boost artificial intelligence development across the country.
3. The Government of Finland launched the Artificial Intelligence 4.0 programme in 2022 for the period 2022–2030. The main objective of the programme is to accelerate the development and adoption of AI and related digital technologies across the economy.
4. The French government supports AI through various initiative programs. For instance, in July 2025, the French government announced that it has launched the national plan “Dare to Use AI”. The main objective of this program is to accelerate AI adoption across all French companies, especially small and medium-sized enterprises (SMEs) and mid-sized companies by 2030. Additionally, it set a goal of 100% of major French companies, 80% of SMEs/mid-sized companies, and 50% of micro-enterprises using AI by 2030. It has three main pillars such as Raising awareness to promote AI adoption, providing training via an AI Academy, and supporting companies to identify relevant AI solutions.
5. In January 2025, Data Center Partners announced its plan to build an AI-ready data center in Munich, with an IT capacity of over 17 MW; this facility will be designed to handle the high-demand AI and Machine Learning (ML) workloads.

Rise in District Heating Concept

1. District heating works like a central heating network, where the waste heat from a central source is supplied to multiple end-users through insulated pipes. District heating networks help data center operators to minimize carbon emissions significantly. Therefore, several data center operators in European countries are increasingly connecting data center facilities to local district heating networks.
2. In February 2026, nLighten signed an agreement to supply waste heat from its data center in Stuttgart, Germany, to the local district heating network. The project is likely to deliver around 1.8 MW of heat, helping support the decarbonization and sustainable energy initiatives of the city.
3. In August 2025, Borealis Data Center signed an agreement with Finnish public utility Loiste Lämpö Oy to capture and reuse waste heat from its data center campus in Kajaani, Finland. The system is expected to become operational by May 2026, with the recovered heat used to supply homes and businesses in the Kajaani region.
