€2.3m grant to develop HTF additives
3rd January 2026
IRELAND: A Dublin-based consortium has received a €2.3m grant to develop heat-transfer-fluid additives that can increase cooling efficiency in data centres, solid-state heat pumps and electric batteries.
The grant from the Irish government’s Disruptive Technologies Innovation Fund has been made to the DLCool consortium led by HT Materials Science (HTMS) in partnership with Dublin City University (DCU) and solid-state heat pump manufacturer Exergyn Ltd.
“This grant advances a critical next phase in the development of heat transfer fluid technology. HTMS has successfully deployed our signature product, Maxwell, with valued partners including Tabreed, Saudi Aramco, Ericsson and Amazon to drastically reduce the energy used to cool their facilities throughout the world. Now, with the support of the Disruptive Technologies Innovation Fund, and with our partners at DCU and Exergyn, we will continue advancing breakthrough technologies that will increase efficiency for an even broader range of next-generation industries,” said HTMS CEO Thomas Grizzetti.
Developed and manufactured by HTMS, Maxwell is a drop-in fluid additive for cooling systems that is said to be able to increase energy efficiency by up to 15% in most commercial and industrial HVAC systems. Non-toxic and fully recyclable, Maxwell is created by suspending sub-micron particles of aluminium oxide in a base fluid of water or glycol. As well as reducing energy consumption, the improved heat transfer also increases system capacity.
The Disruptive Technologies Innovation Fund (DTIF) is a challenge-based €500m fund established under the Irish government’s National Development Plan (NDP) in 2018.
