COMMUNITY DATA CENTRES

INFRASTRUCTURE

A data centre is more than its GPUs

Useful distributed compute requires the same underlying disciplines as any other infrastructure asset: power quality, cooling, service access, network resilience, safety, monitoring and lifecycle maintenance.

Protected, replaceable compute

The current baseline uses one server with four NVIDIA A10 accelerators and local NVMe storage. Future compute classes can change without redefining the rest of the node.

Power is an architecture, not a plug

CEAC combines conditioned power, battery storage, electrical distribution and generation interfaces so compute can be managed as an infrastructure load rather than an isolated server.

Grid, battery and local generation can work together according to the requirements and resources of each site.

Directed cooling with independent failsafe

The current engineering model uses a directed recirculating air path across the compute rack, with primary fan-coil cooling and an independent DX failsafe system.

Temperature and humidity monitoring is intended across rack inlet, exhaust, supply, return, room, battery, UPS and outdoor conditions.

Designed to be maintained

The current physical model explicitly considers rack-front access, rack-rear service space, main aisle clearance, equipment removal paths and separation of compute, power and safety systems.

Measure the infrastructure you intend to improve

Each node is designed to monitor facility power, compute utilisation, temperature, network traffic and system state, creating an operational picture of how the infrastructure is performing.

One compute architecture. Multiple energy profiles.

CEAC is designed around a common compute and infrastructure platform with an energy architecture selected for the site.

CEAC-GRID

Grid-connected infrastructure with protected power and optional local generation.

CEAC-PV/ESS

Solar and battery-led infrastructure for suitable sites.

CEAC-BIO

Bioenergy-supported infrastructure where local feedstock and energy conditions support it.

CEAC-FLEX

A mixed energy architecture combining the resources available at the site.

The compute platform remains consistent while the energy system can adapt to local conditions.

CEAC separates the compute architecture from the energy source, allowing different communities and sites to use different combinations of grid power, storage and local generation.

CEAC-BIO

CURRENT MODEL

The current digital twin includes a containerised bioQUBE anaerobic-digestion system coupled to a powerQUBE combined heat and power unit, demonstrating how locally available bioenergy can be integrated with the CEAC platform.

Carbon by design

Distributed infrastructure creates an opportunity to understand carbon at the level of the service being delivered — from the equipment inside the CEAC to the electricity, cooling, storage, connectivity and local energy systems that support it.

CEAC is being developed with carbon measurement built into the engineering model so operational and embodied impacts can be assessed as the platform develops.

COMPARATIVE

CEAC service path compared with the equivalent remote service path

Comparative carbon analysis will evaluate the CEAC and remote delivery paths against the same defined digital service.

Grid electricity reference

Using the current Generation-1 annual electricity model of 15,586.93 kWh and the 2026 UK grid conversion factor of 0.13096 kgCO2e/kWh gives an operational electricity reference of approximately 2.04 tCO2e per CEAC-year, equivalent to around 20.4 kgCO2e per household per year across 100 households.

The full CEAC carbon model also considers infrastructure, local generation, storage, cooling, connectivity and lifecycle impacts.
