The UK is grappling with a pressing need for secure and sustainable computing infrastructure to support its rapidly advancing AI ambitions. To address this, Carbon3.ai has unveiled a £1 billion investment plan to convert legacy industrial and energy sites into a nationwide network of data centres powered entirely by UK-owned renewable energy.
Founded by Mick McNeil and Joseph Parry, Carbon3.ai seeks to secure the UK’s strategic independence in AI infrastructure. Their vision is to build a scalable, sustainable, and sovereign AI ecosystem that sets a new standard for the nation.
Technologically, Carbon3.ai stands out by combining off-grid renewable energy generation with advanced AI hardware and software, working alongside partners such as Hewlett Packard Enterprise, VAST Data, and World Wide Technology. Their platform will deploy over 100,000 GPUs in secure, low-carbon data centres engineered for resilience and regulatory compliance.
The company leverages renewable energy assets and owned land to create a distributed AI infrastructure mesh spanning more than 30 sites across the UK. The infrastructure is designed to be carbon-neutral by design, passing verified carbon credits directly to customers and delivering lower operational costs thanks to affordable, renewable power.
Looking ahead, Carbon3.ai plans to open its first 5MW site in the East Midlands by March 2026, with further facilities planned across the country to meet the UK government’s target of 6GW of sovereign AI capacity by 2030.
