The Potential of Space-Based Data Centres in Europe
CIO Review Europe | Friday, December 27, 2024
The ASCEND project explores the feasibility of space-based data centres in Europe, aiming to reduce energy consumption and carbon emissions while enhancing digital sovereignty amid rising demands from AI technologies.
FREMONT, CA: The increasing demand for data centres, driven by the rapid expansion of artificial intelligence (AI), has prompted Europe to explore innovative solutions for digital storage. One such initiative is the Advanced Space Cloud for European Net Zero Emission and Data Sovereignty (ASCEND) project, which aims to assess the feasibility of launching data centres into orbit. This 16-month study, coordinated by Thales Alenia Space on behalf of the European Commission, has yielded promising results, suggesting that space-based data centres could be technically, economically, and environmentally viable.

As AI technologies advance, data centre energy requirements have surged. Current projections indicate that global electricity consumption from data centres could exceed 1,000 terawatt-hours by 2026, comparable to Japan's total consumption.
AI-specific data centres are estimated to consume up to three times more energy than traditional facilities, raising concerns about sustainability and resource management. The ASCEND study proposes that relocating some data processing capabilities to space could alleviate these pressures by harnessing solar energy, which is abundant and uninterrupted by terrestrial weather conditions.
Feasibility and Environmental Impact
The ASCEND study concluded that deploying data centres in space is feasible and presents a significant opportunity to reduce carbon emissions associated with digital infrastructure. The project envisions launching modular building blocks into low Earth orbit at an altitude of approximately 1,400 kilometres. Each block would have a capacity of 10 megawatts and cover a surface area of 6,300 square meters. By 2036, the goal is to deploy 13 such blocks as a starting point for commercial cloud services in space.
However, to achieve substantial reductions in CO2 emissions, the development of a new type of launcher with emissions ten times lower than current models is essential. ArianeGroup is among the companies working on this eco-friendly launcher technology, aiming for its first operational version by 2035. This initiative aligns with the European Union's objective of achieving carbon neutrality by 2050.
Economic Viability and Strategic Implications
The ASCEND project is projected to yield returns amounting to several billion euros by 2050, making it an economically attractive proposition. These findings could revolutionise the European digital landscape by providing a more sustainable and sovereign solution for data hosting. Furthermore, discussions are ongoing with the International Space Agency to consolidate findings and develop heavy-lift launchers necessary for deployment.
However, experts caution that while space-based data centres represent an innovative approach to managing energy consumption in the tech sector, they are not a comprehensive solution. Significant amounts of rocket fuel would still be required to maintain these facilities in orbit, which poses environmental challenges.
The ASCEND initiative exemplifies Europe's proactive strategy in addressing the growing demands of AI and digital infrastructure through innovative solutions like space-based data centres. While promising in terms of sustainability and economic viability, further research and development are necessary to overcome technical challenges and ensure this concept can be integrated into Europe's broader digital strategy. As Europe seeks to enhance its competitiveness in the global tech landscape, projects like ASCEND may play a crucial role in shaping the future of data management and energy consumption.
