This year, Submer is thrilled to welcome the global Open Compute Community to our hometown of Barcelona, a city where innovation, sustainability, and digital transformation thrive. Submer will participate in OCP EMEA 2026; this year’s Summit will be held April 29-30.

Launching our new AI inference Reference Design with 2CRSi 

The global race toward AI adoption is accelerating faster than ever. As AI scales, the challenge is how efficiently compute can be powered, cooled, and deployed.

GPUs are harder, and more expensive, than ever to deploy at scale

In reality, the bottleneck is shifting from access to compute, to how much intelligence can be delivered per watt of power. To solve this, during OCP EMEA 2026, Submer, together with 2CRSi and Eneos, are introducing a transformative new reference design. A hybrid liquid cooling architecture for scalable, ready‑to‑deploy AI inference. This plug-and-play solution integrates: 

  • Immersion‑cooled GPU clusters 
  • Networking 
  • Storage 
  • Full management stack


Pre‑validated architecture for rapid deployment 

Whether you’re scaling edge inference, LLM serving, or specialized acceleration workloads, this reference design reduces integration risk, shortens deployment timelines, and delivers predictable performance at lower operational maximizing performance per watt across the deployment. It’s AI infrastructure, without the friction. 

Redefining efficiency for AI in Europe 

As part of our roadmap for OCP EMEA 2026, we will present a real-world AI datacenter use case based on an ORV3 configuration, targeting an industry-leading 1.09 PUE. This deployment reflects a critical reality for Europe’s AI ambitions to accomplish ultra‑efficient infrastructure is no longer optional. Driving PUE as low as possible is foundational to enabling sovereign, sustainable, and economically viable AI at scale, supporting performance growth while respecting energy responsibility and regional autonomy. 

Driving sustainability forward, Submer leads an OCP Heat Reuse Subproject

As part of our long‑standing commitment to more sustainable digital infrastructure, during OCP EMEA 2026, Submer will also participate in the keynote: 

“8114 – Heat Reuse Subproject Update: 
Heat Reuse Platform initiative, Policies, Reference Design, and Economics” 

Gabriel Lazar, alongside industry experts Alberto Ravagni, Petter Terenius, and Jack Kolar, will present the latest developments in: 

  • The OCP heat reuse platform
  • Real-world demos
  • Context and next steps for the Reference Design subproject
  • Policy frameworks enabling adoption at scale

Heat reuse is increasing in maturity becoming a critical pillar of sustainable datacenter design. Submer is proud to help shape the standards and technologies that will scale this circular initiative globally. 

With all the above insights, we hope you are inspired to stop by Submer’s booth B5 during OCP EMEA Barcelona, to meet the team and learn more about our latest initiatives. Hosting OCP EMEA 2026 in Barcelona is more than symbolic for Submer. This city represents our roots, our community, and our belief that technology can, and must, move the world toward a more sustainable future.
