Around the Alliance #5: Low carbon power consumption for data centers

We hosted our 5th Around the Alliance session live on LinkedIn on Tuesday, 16 November at 15:00 CET.


What was the session about?

Data centers are under pressure to decarbonize without compromising uptime, resilience, and cost. Our expert panel discussed the challenges and opportunities, sharing their insights on the many trends happening right now in the data center energy consumption space.

Key takeaways

  • Today still there is no such thing as carbon-neutral renewable power supply. In order to become climate-neutral you have to find solutions for capturing, utilizing, or storing carbon.
  • There is no difference in power quality between renewable and fossil-fuel sources.
  • Consider energy as a system and factor in distribution losses.
  • There were various perspectives on back-up generators ranging from data centers still need them, but powered by green energy, to they are not needed dependent on the data center set up - availability requirements and workloads.
  • It is essential to find new and innovative ways of reusing waste heat, together with transparent metrics as an industry standard.
  • Building a circular economy around data centers is a long-term solution, achievable with vision and a lot of collaboration with multiple parties.
  • For sustainable data centers in the future, hydrogen fuel cells are on the brink of scalability.
  • Potential changes for making data centers greener: using laminated wood, liquid cooling, renewable back-up power generation, waste heat reuse, and energy-efficient software.


This Around the Alliance session was moderated by our Director of Policy & Research, Mohan Gandhi, and featured six panelists with amazing insights into the data center industry and the topic of low carbon power consumption:

Andreas Espeving, Senior Key Account Manager - Vattenfall
Armin Fürderer, Director of Hydrogen Solutions - Rolls-Royce Power Systems
Fiete Dubberke, CEO – windCORES
Lars Schedin, Senior Advisor – EcoDataCenter
Niek van der Pas, Lead Data Centre Expert – Legrand
Rob Elder, VP Data Centers – 


Want to join the work on the collaborative White Paper?

Join us in Stockholm on the practical workshop focused on the technical & financial barriers and opportunities around on-site low-carbon power generation in data centers. Together with workshop sponsors - Legrand and Vattenfall we have invited all the parties involved in the value chain, including regulators, policy-makers, industry players, universities, and research centers, to join us in shaping the actionable solutions and setting the basis for in-depth project research. The workshop is free to attend and includes canapes. The number of seats is limited, please book via the following link »
