UK-based Carnot Engines expands testing and manufacturing capability in Milton Keynes to bring high-efficiency, multi-fuel engines to market

Carnot Engines, the UK startup developing next-generation high-efficiency engines, has agreed contracts to significantly expand its Bletchley, Milton Keynes facilities—tripling its operational footprint as it enters the next phase of commercial growth.

Since establishing its base in Bletchley in September 2024, Carnot has built a state-of-the-art engine test facility from the ground up. Over the past 18 months, the team has focused on validating its core technology—optimising engine performance and efficiency across multiple fuel types. With the underlying technology now proven, Carnot is moving into the next phase: preparing its engines to go to market.

Scaling testing capability for market readiness

The first phase of expansion includes securing an adjacent site, which will house a new durability and accelerated life testing centre. Three new test cells will be built including a dedicated gaseous fuel test cell designed to run LPG, biogas, and natural gas for Petredec Global. These facilities will significantly increase testing capacity, enabling higher run-hours and providing the validation required for customer deployment. This expanded capability is a critical step in demonstrating long-term reliability and accelerating adoption of Carnot’s technology across distributed power and industrial applications.

 

Callum Anderson, MP visits carnot

Callum Anderson, MP,

Member of Parliament for Buckingham & Bletchley

“It’s fantastic to see Carnot continuing to grow and invest here in Bletchley. Having visited their site, I’ve seen for myself the cutting-edge work they’re doing to develop cleaner, more efficient engine technology. This is exactly the kind of innovation we need to drive forward our net zero ambitions nationally while creating skilled jobs locally.

This expansion is a real vote of confidence in our area as a hub for advanced engineering and future-facing industry – one that will only grow stronger with the development of the Oxford-Cambridge Growth Corridor. I look forward to seeing them go from strength to strength in the years ahead, and will continue to champion companies like Carnot through my Bletchley Investment Taskforce work.”

 

Strengthening technical leadership

Supporting this expansion is the appointment of Technical Advisor James Garner, a specialist in the design and construction of advanced testing facilities for Automotive, Aerospace and Vehicle across ICE, Batteries and Hydrogen applications.

James has worked with leading organisations across Formula 1, automotive, and industrial manufacturing. His expertise has been instrumental in streamlining facility design, ensuring regulatory compliance, particularly for gaseous fuels, and delivering a test environment capable of producing consistent, repeatable, high-quality data.

 Building toward production

A third site provides flexible space for fabrication and assembly. Initially, this facility will be used to build Carnot’s field demonstration rigs—early generator systems designed to deliver power on customer sites. It will also serve as a development hub for manufacturing processes, supporting the transition to full-scale production, with first commercial units targeted for 2027.

Accelerating the path to low-cost, decarbonised power

Carnot’s long-term vision is to become a global leader in next generation engine systems — reducing both the cost and emissions of power generation. This expansion marks a major milestone in that journey.

Carnot would like to thank its partners and collaborators who have supported this next phase of growth.
