Initial capital secured & over £1bn planned, Carbon3.ai’s nationwide AI Mesh will deploy 100,000 GPUs across its owned land and power assets – generating its own renewable energy to deliver trusted, sustainable AI for UK enterprises and government

LONDON, Sept. 26, 2025 /PRNewswire/ —Carbon3.ai, the UK AI solutions platform, today announced its plans to deliver the UK’s first sustainable sovereign AI platform later this year, a vertically integrated ecosystem spanning renewable energy generation, a nationwide mesh of data centres, and an enterprise AI software stack. Backed by significant initial UK capital and a planned £1bn growth programme, and underpinned by the experience, expertise and leading solutions of technology partners HPE, VAST Data and WWT, Carbon3.ai is positioning itself as the ‘National Grid for AI’, enabling UK enterprises and government to operationalise AI faster, greener, and with full sovereignty.

Carbon3.ai’s launch comes as the UK government advances a multi-phase energy strategy, balancing nuclear investment with renewable innovation to meet surging AI-driven power demand. By focusing on renewables and sovereign ownership, Carbon3.ai complements these national priorities, providing a homegrown alternative to foreign-led nuclear initiatives and ensuring that the UK’s AI infrastructure can scale responsibly, sustainably, and securely.

Designed to be both sovereign and sustainable, Carbon3.ai is UK-owned, UK-operated, and powered by off-grid renewable energy. For customers, that means two things: every workload runs with a smaller carbon footprint and at a lower cost, thanks to our ability to generate affordable renewable power. Carbon3.ai is the first UK AI platform to pass verified carbon credits and genuine cost savings directly to customers.

With its distributed nationwide infrastructure, Carbon3.ai’s mesh has been designed with the capacity to deploy more than 100,000 next-generation GPUs across its sites as demand scales. This will enable UK organisations in every region of the UK to access low-latency, high-performance AI compute for the first time.

“The UK can’t lead in AI if it doesn’t have a sovereign backbone that powers it,” said Mick McNeil, Co-Founder & Chief Business Officer at Carbon3.ai. “Carbon3.ai provides that backbone at national scale, and in doing so, it becomes the launchpad for sovereign innovation. AI is the new critical infrastructure, and to be trusted it must be sovereign, sustainable, and scalable. With Carbon3.ai, the UK takes control of its AI future, securing the data, the energy, and the economics that will define the next decade.”
