Haydale Launches Graphene Heat-Transfer Fluid - Expanding Its Commercial Platform Into Advanced Cooling Applications
Launch of Second
The patented graphene-enhanced fluid extends Haydale's HDPlas® plasma-functionalisation technology into the multi-billion-pound global cooling and thermal-management market, directly addressing one of the most critical physical constraints on modern computing and digital-infrastructure growth: heat dissipation.
Highlights
· Second key commercial pillar: Expands HDPlas® graphene technology from heating into the global cooling and thermal-management market, targeting the rapidly growing data-centre and high-performance-computing (HPC) sectors where efficient heat control is now mission-critical.
· Patent protection secured: Notice of Intention to Grant received from the
· Strategic commercialisation agreement: Partnership with
· Engagement with global manufacturer: Non-binding Letter of Intent received from a leading US-based global manufacturer of electric vehicles and energy systems to evaluate the patented fluid for next-generation power-device cooling.
· Growing
· Transformational timing: Positions Haydale among the few listed companies developing solutions to address the energy-efficiency challenge created by rising global computing power resource demand, with data-centre electricity consumption expected to triple by 2030.
Background
The development of Haydale's graphene-enhanced heat-transfer fluid was part-funded by the
Haydale has received a Notice of Intention to Grant from the
To accelerate commercial deployment, Haydale has signed an agreement with
Liquitherm brings over 25 years' experience in mission-critical cooling infrastructure, providing manufacturing capability and access to established HVAC and data-centre customers across the
In parallel, Haydale has received a non-binding Letter of Intent from a leading US-based global manufacturer of electric vehicles and energy systems to evaluate the Haydale Technology for advanced thermal-management systems used in next-generation power-device cooling. This engagement underscores rising interest from Tier-1 global manufacturers in Haydale's patented graphene materials platform.

The Thermal Enabler of the Next Industrial Revolution
The industrial cooling sector is one of the largest yet least-recognised levers for global energy efficiency and decarbonisation. Soaring computing-power demand is driving an unprecedented rise in data-centre energy use - with cooling already accounting for up to 40 per cent of total facility power consumption and overall electricity demand forecast to triple by 2030.
The combination of AI expansion, high-performance computing, and growing pressure on electricity grids is creating urgent demand for advanced cooling solutions that can deliver higher efficiency without costly infrastructure upgrades - a challenge directly addressed by Haydale's graphene-enhanced heat-transfer fluid. Infused with plasma-functionalised graphene nanoparticles, the fluid delivers substantially higher thermal-transfer efficiency than conventional coolants, directly reducing energy consumption and carbon emissions.
"From graphene to gigawatts,
Throughout 2025, we've been developing graphene-enabled solutions that improve the movement and management of heat - first through JustHeat™ and now through advanced cooling.
Just as silicon enabled computing, graphene will enable the next generation of high-performance systems. Our technology closes the thermal gap that silicon opened."
Outlook
With JustHeat and now its graphene-enhanced heat-transfer fluid, Haydale has established the two core pillars of its commercial platform - heating and cooling - each built on its scalable HDPlas® technology. As compute loads surge and energy efficiency becomes a global priority, Haydale's fluid enters the market at a time when demand for energy-efficient cooling is increasing.
While these agreements are not expected to generate immediate commercial revenues, they represent the next phase in the disciplined commercialisation of the Haydale Technology - moving from successful laboratory validation into controlled field trials with commercial partners. These programmes are designed to demonstrate real-world performance and scalability, but there can be no assurance of success or of future revenues arising from them.
This launch therefore marks another measured step in Haydale's long-term strategy to build a scalable, graphene-enabled technology platform delivering practical decarbonisation solutions and foundational materials for the global energy-efficiency transition.
