Fuse Energy bets on NVIDIA GPUs as it expands from energy supply into AI infrastructure

Fuse Energy, a British energy company, has opened reservations for Fuse Compute, its first commercial AI product, offering access to NVIDIA GPUs in UK data centres powered by Fuse – marking a new step into AI infrastructure by the EnergyTech startup.

Interested parties can register interest and reserve capacity today, with the first GPUs slated to come online in December 2026. The ambition here is to own the full AI stack: power, land, data centres and AI compute.

“Power is the biggest hurdle to building AI infrastructure, and it’s the part we already know how to do,” says Alan Chang, CEO and co-founder of Fuse Energy. “Every AI company is fighting for the same scarce GPUs, and the grid can’t connect data centres fast enough to keep up. Fuse Compute puts that expertise to work for the companies building the future of intelligence, and makes sure that future is built in Britain.”

This is an interesting new direction for an energy company whose focus is simplyfying gas and electricity management. Fuse has raised €178 million ($199 million) since its founding in 2022.

Our earlier coverage traces Fuse’s expansion from supplying 50,000 UK homes in July 2025, when it reported €76 million in annualised revenue and raised €8.5 million, to more than 200,000 households and €341 million in annual recurring revenue by December, when it secured another €59 million.

By June 2026, Fuse was supplying more than 300,000 households and had closed a €25 million Series B extension, while reporting monthly EBITDA profitability since December 2025.

Its expansion into AI compute comes amid significant funding for companies developing the underlying infrastructure. In the UK, Nscale raised €1.7 billion for vertically integrated AI compute, Volta reportedly secured €259.8 million across two rounds to develop AI factories, and Orbital Industries raised €43 million for industrial hardware including data-centre technologies.

Elsewhere, Finland’s Verda raised €164.8 million for AI cloud expansion and Spain’s iPronics secured €107.6 million for optical networking. These 2026 infrastructure financing announcements totalled approximately €2.4 billion, excluding Fuse’s historical funding.

The company says that AI is creating more demand for compute than the UK can supply. The UK Government’s Compute Roadmap estimates the country will need at least 6GW of AI-capable data centre capacity by 2030, yet new data centres face waits of up to a decade for a grid connection.

Power has become the main constraint on how quickly that capacity can be built. The Government aims to expand the UK’s public compute capacity 20x by 2030, but the country has few home-grown providers of large-scale compute, leaving many British AI companies reliant on capacity hosted overseas.

Fuse’s move into compute builds on its experience in power. Its most recent solar site was built at around 30% below the industry average cost per megawatt. It holds a power generation pipeline of more than 1GW and a data centre connection pipeline of 142MW across 15 projects. This will allow it to energise and construct high-density AI sites quickly and cheaply.

Fuse Compute will offer bare-metal, single-tenant NVIDIA GPU nodes in UK data centres, with UK jurisdiction and a UK data path. The first 128 NVIDIA B300 GPUs are due to come online in December 2026, followed by 1,024 in Q2 2027, a further 22MW in Q4 2027 and 116MW from 2028.

In energy, Fuse already supplies 470,000 UK homes and holds both supplier and meter operator licences.

On the supply side, Fuse owns and operates low carbon generation assets, with 22 MW active and over 1 GW in the pipeline across the UK, US, and Europe.

For the company, keeping compute onshore means that the data will stay under UK jurisdiction, and that British AI companies will no longer need to rely on overseas capacity.

Fuse’s near-term data centre projects will also reportedly bring 250 construction and operational jobs to the UK, and represent €1.1 billion (£1 billion) of investment in UK infrastructure.
