Haydale Graphene Industries has announced the launch of a graphene-enhanced heat-transfer fluid - the second key pillar in the Company's long-term commercialization strategy.
The patented graphene-enhanced fluid extends Haydale's HDPlas® plasma-functionalization 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.
This is the Company's second key commercial pillar, that expands HDPlas® graphene technology from heating into the global cooling and thermal-management market, targeting the rapidly growing data-center and high-performance-computing (HPC) sectors where efficient heat control is now mission-critical.
Patent protection has reportedly benn secured, as Notice of Intention to Grant was received from the UK Intellectual Property Office for GB 2625980, covering the use of surface-functionalized graphene particles in heat-transfer and thermal-management fluids for heating and cooling systems.
As part of Haydale's strategic commercialization agreement, a partnership with Liquitherm Technologies Group (trading as Hydratech), the UK's leading formulator and supplier of specialist heat-transfer fluids, has been drafted to jointly commercialize the patented fluid across domestic, industrial and data-center applications, including direct-to-chip liquid-cooling circuits.
In addition, a Non-binding Letter of Intent was reportedly received from a leading U.S-based global manufacturer of electric vehicles and energy systems to evaluate the patented fluid for next-generation power-device cooling.
Haydale also reported two new Memoranda of Understanding signed with UK data-center design specialists to trial the patented fluid within data-center cooling systems in South Wales and other UK locations.
The development of Haydale's graphene-enhanced heat-transfer fluid was partly funded by the Welsh Government under the SMARTCymru initiative, supporting final laboratory validation and corrosion-testing stages undertaken in collaboration with Liquitherm Technologies Group (trading as Hydratech).
Simon Turek, CEO of Haydale, commented: "From graphene to gigawatts, South Wales is quietly building the materials engine of the modern digital economy, and Haydale is proud to be contributing at its center. 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."
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 commercialization of the Haydale Technology - moving from successful laboratory validation into controlled field trials with commercial partners. These programs are designed to demonstrate real-world performance and scalability, but there can be no assurance of success or of future revenues arising from them.
