It has signed agreements with Liquitherm Technologies Group and Levidian Nanosystems to bring its technology to market
West Wales firm Haydale has moved closer to commercialising its patented technology to support data centres use less water and energy.
The Ammanford headquartered advanced materials and clean tech venture has successfully tested its patented super-efficient thermal transfer fluid (SETTF), a graphene-based additive intended for use with glycol coolants in data-centre cooling systems.
In testing SETTF achieved a thermal conductivity approximately 28% above that of the baseline inhibited glycol coolant, restoring it to the level of pure water while retaining the freeze, corrosion and fouling protection for which glycol is required.
For data centres this has the potential to provide additional cooling headroom from existing infrastructure, which may be used to run processors cooler, reduce cooling energy and flow requirements, or support greater compute capacity.
Glycol coolants are widely used in data-centre cooling, building climate control, industrial process cooling and refrigeration. Adding glycol provides essential freeze protection, but at the cost of reduced thermal performance.
Where electrical power is the limiting factor on data centre capacity, recovered thermal headroom provides significant economic value.
Based on modelling Haydale estimates that an additional degree of usable operating headroom could represent approximately $3m to U$4m per annum of gross capacity value for a 50 megawatt facility.
To support the commercialisation of SETTF, Alternative Investment Market listed Haydale has signed agreements with Liquitherm Technologies Group – which trades a as DC Cooling Solutions – and Levidian Nanosystems, to establish a supply chain and route to market.
The partners are in discussions with data centre operators representing approximately 200 megawatt of capacity, with first installations targeted within next 12 months.
Fundraising, completely separate from Haydale, will be undertaken to support commercialisation efforts.
JLL forecasts approximately 97 gigawatt of new data-centre capacity between 2026 and 2030, with approximately 80% of new facilities expected to adopt liquid cooling.
Chief executive of Haydale, Simon Turek, said: “The simple result is that SETTF increased the thermal conductivity of a glycol coolant by approximately 28%, restoring it to the level of pure water. In practical terms, that means a data centre could potentially get more cooling performance from the same infrastructure, without giving up the freeze and corrosion protection for which glycol is required.
“For a data centre operator, better heat transfer means more thermal headroom. That headroom can be used to run processors cooler, reduce the energy and flow required for cooling, or support more compute from the same cooling infrastructure. As AI chips become hotter and rack densities increase, we believe that becomes increasingly valuable.
“We now have application-tested technology, protected IP, production capacity at Ammanford and commercial agreements establishing our supply chain and route to market. Our priorities are now clear: complete qualification, convert the approximately 200 megawatt of active operator discussions into first deployments, and secure dedicated external capital for the venture.”
Ian Hopkins, chief commercial officer of Levidian, said: “SETTF represents an exciting, high-value application for our G3 graphene. Levidian brings both materials-science capability and an international production platform that can support the venture as it scales into the markets where AI infrastructure investment is growing most rapidly.
“We look forward to working with Haydale and Liquitherm on qualification and first commercial deployments.”
Stephen Hickson, chief executive of Liquitherm Technologies Group, said: “The SETTF test results are very encouraging. Our focus is now on qualification and integration into our data-centre cooling fluid range and similar HVAC (heating, ventilation and air conditioning) environments served by the Liquitherm group and our global partners.”
Haydale’s UK patent runs until 2042.
