Haydale Launches Graphene Heat-Transfer Fluid - Expanding Its Commercial
Platform Into Advanced Cooling Applications

Launch of Second Key Pillar in Haydale's Commercialisation Strategy

 

Haydale Graphene Industries plc (AIM: HAYD), the advanced-materials group,
today announces the launch of a graphene-enhanced heat-transfer fluid - the
second key pillar in the Company's long-term, disciplined commercialisation
strategy.

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 UK Intellectual Property Office for GB 2625980, covering the use of
surface-functionalised graphene particles in heat-transfer and
thermal-management fluids for heating and cooling systems.

·      Strategic commercialisation agreement: Partnership with
Liquitherm Technologies Group (trading as Hydratech), the UK's leading
formulator and supplier of specialist heat-transfer fluids with over 25 years'
experience, to jointly commercialise the patented fluid across domestic,
industrial and data-centre applications, including direct-to-chip
liquid-cooling circuits.

·      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 UK ecosystem: Two new Memoranda of Understanding signed
with UK data-centre design specialists to trial the patented fluid within
data-centre cooling systems in South Wales and other UK locations.

·      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 Welsh Government under the SMARTCymru initiative,
supporting final laboratory validation and corrosion-testing stages undertaken
in collaboration with Liquitherm Technologies Group (trading as Hydratech).

Haydale has received a Notice of Intention to Grant from the UK Intellectual
Property Office for patent GB 2625980, covering the use of
surface-functionalised graphene particles in heat-transfer and
thermal-management fluids (the Haydale Technology). The patent defines a new
class of graphene-enabled coolants capable of improving energy efficiency
across industrial, domestic and digital-infrastructure systems where power
densities are increasing sharply.

To accelerate commercial deployment, Haydale has signed an agreement with
Liquitherm Technologies Group Ltd, the UK's leading formulator and supplier of
specialist heat-transfer fluids, to jointly commercialise the Haydale
Technology across domestic, commercial and data-centre applications, including
direct-to-chip liquid-cooling circuits.

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 UK and Europe. Through its Thermal
Energy Optimisation Programme, Liquitherm manages coolant specification,
installation and performance for leading data-centre, renewable-energy and
industrial customers, with a proven reputation for technical rigour and
reliability.

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.

Haydale has also signed two Memoranda of Understanding with UK-based designers
of modular and high-performance, energy-efficient data-centre infrastructure
to test and validate the Haydale Technology within data-centre cooling systems
in South Wales and other UK locations.

South Wales is rapidly emerging as the UK's centre for data-centre and
digital-infrastructure investment, with major projects across the Vale of
Glamorgan, Cardiff and Bridgend. Within 50 km of Haydale's Ammanford
facilities, a new ecosystem - the "Thermal Valley" - is forming, linking
compute infrastructure, advanced materials and government-backed
decarbonisation initiatives.

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.

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 centre.

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.
