Maarten Trautmann, Oleon: Plant-Based Fluids, Energy Reuse & the Liquid Cooling Opportunity Europe's Missing

Cooling Data Center Podcast

What if we could decarbonise IT… by rethinking the liquid?

In this episode, Maarten Trautmann of Oleon joins Robert to unpack why plant-based dielectric fluids aren't just a greener alternative - they may be the key to unlocking waterless, sustainable cooling at the edge, at scale, and across Europe.

From his early fascination with Ireland to leading Oleon's charge into liquid cooling, Maarten shares how Oleon's biodegradable, non-toxic fluids are offering a credible path to closed-loop cooling, heat reuse, and decarbonisation - without compromising performance.

Together, they dive into:

• The surprising history of Oleon (yes, it started with candles)
• Why Europe is missing the mark on incentivising heat reuse
• How immersion cooling adoption is being throttled by warranty fears and retrofitting costs
• Why innovation in cooling is still in full swing - and where consolidation might come next

If you're interested in liquid cooling beyond just AI hype, this one's for you.
