Clean Back-Up Power



The Clean back.up power work stream explores promising pathways for backup and prime power needs for next-generation, high-demand data centers. 


About the Clean Back-Up Work Stream






Back-up power is a necessary requirement in data center design to guarantee uptime and resilience. The powerful and redundant energy assets can instantly and seamlessly take over the entire data center load, and they arer typically used only in the rare event of a grid failure.


The work stream aims to validate clean back-up solutions as alternatives to diesel back-up.


Hydrogen, Renewable Natural Gas and Methanol are among the clean fuels being considered, alongside Internal Combustion Engines, Turbines, Linear Generators and Fuel Cells as potential conversion devices.

Why Clean Back-up Power?


With AI-driven load growth accelerating, data center operators are prioritizing supply certainty, rapid deployment, and decarbonization. Industry analysts anticipate that behind-the-meter and hybrid energy systems in new-build data centers will increase from 10–20% in 2025 to 50–60% by 2030, underscoring the need for scalable, low-carbon alternatives to diesel-based backup systems.


Considering that in Europe alone, 25 GW of new data centers could be built by 2030, back-up power systems represent a formidable, unutilized potential for the European electric system. They could provide flexibility, stabilize the grid and support the grid connection of intermittent renewable energy sources. 

 

A common back-up power design consists of UPS, batteries and diesel back-up generators. Innovative, zero emissions back-up solutions would enable a more frequent utilization of these energy assets and their alignment to evolving regulation.

Key Questions to address in the Work Stream






  • Identify and validate alternative back-up solutions
  • Ensure scalability and reliability
  • Support decarbonization and sustainability
  • Target Net Zero Scope 1 emissions with at least 80% reduction compared to fossil-fuel alternatives
  • Assess full environmental impact through lifecycle analysis (LCA) and material reporting
  • Minimize water consumptions and other ecological footprints.
  • Optimize economic and commercial viability
  • Enhance grid and microgrid integration
