Era4

Era4 (formerly Carbon3.ai) is building the UK’s sovereign, secure, and sustainable AI platform. Vertically integrated to bypass grid constraints, the company transforms legacy industrial sites into high-performance, lower-carbon AI data hubs powered by independent, off-grid energy sources.

All data processing and infrastructure remain strictly within UK jurisdiction. Operating over 40 nationwide sites, Era4 deploys high-density, liquid-cooled architectures equipped with NVIDIA HGX B-series chips. Backed by partnerships with technology leaders like HPE, WWT, and Civo, Era4 provides low-latency, scalable AI compute to secure the UK's sovereign digital future.

Era4 Locations

The Carbon3.ai AI data center is a planned modular facility located adjacent to the Erin Landfill and Valencia Energy Centre in Duckmanton, Derbyshire.

The proposed Carbon3.ai data center at Amlwch Port, Anglesey, is a centerpiece of the UK’s newly designated AI Growth Zone, transforming the derelict 61-acre Octel chemical plant into a high-capacity "Sovereign AI" hub.
