HT Materials Science consortium awarded €2.3M grant for liquid cooling tech
HT Materials Science (HTMS), in partnership with Dublin City University (DCU) and solid-state heat pump manufacturer Exergyn Ltd., has secured a €2.3 million (approx. USD 2.6 million) grant from Ireland’s Disruptive Technologies Innovation Fund (DTIF) to develop direct-liquid cooling technology.
The funding supports DLCool, a consortium led by HTMS and based at the DCU Innovation Hub. The project aims to develop advanced heat-transfer fluid additives designed for applications in data center cooling, solid-state heat pumps, and electric battery systems.
HTMS’s additive technology, including its flagship product Maxwell, will be central to the project. Maxwell is a drop-in fluid additive that enhances energy efficiency in commercial and industrial HVAC systems by up to 15%. It contains sub-micron aluminum oxide particles suspended in a base fluid of water or glycol. The product is non-toxic and fully recyclable.
The Disruptive Technologies Innovation Fund, launched under Ireland’s National Development Plan in 2018, is a €500 million initiative managed by the Department of Enterprise, Tourism and Employment with support from Enterprise Ireland. It is intended to foster collaboration between industry and research institutions and promote commercial deployment of advanced technologies.
“This grant advances a critical next phase in the development of heat transfer fluid technology,” said Thomas Grizzetti, CEO of HTMS. “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.”
