Special Report: Green Critical Minerals has signed a collaboration agreement with leading Australian data centre operator GreenSquareDC that confirms real-world, commercial interest in its very high density graphite technology.
Green Critical Minerals signs collaboration agreement with major data centre operator GreenSquareDC
Deal covers development and provision of VHD Graphite thermal management products for data centres
Agreement confirms real-world, commercial interest in the technology's potential to meet next generation heat management needs
Under the agreement, which is part of an ongoing targeted customer qualification and engagement program, the companies will collaborate in the development and provision of thermal management products for GreenSquareDC's data centres using VHD Graphite.
Over 24 months both parties will assess the commercial viability of jointly developed, specially designed thermal management products and share relevant intellectual property and confidential information for the purpose of the collaboration.
Green Critical Minerals (ASX:GCM) has been steadily demonstrating the potential of its VHD Graphite technology to meet the needs of industries requiring next-generation advanced engineered graphite and thermal solutions.
Its technology has consistently manufactured a product with the highest density (2071kg/m3) recorded for VHD blocks while the average density of 2011kg/m3 easily exceeds industry standard densities for nuclear graphite (1700-1900kg/m3), which is used as a high-temperature control-rod material, and electrode graphite (1550-1800kg/m3) used in batteries.
Testing also found that its VHD Graphite blocks had 3x better thermal diffusivity than aluminium and graphite, 2.6x better than copper as well as a 25x directional advantage.
More recently, an experienced company with expertise in the design and supply of heat sinks to the high-performance electronics and electrical systems sector progressed to Stage 2 of the qualification process after machining a VHD Graphite heat sink.
This confirmed the real-world form factor and production viability of GCM's VHD Graphite.
Collaboration validates strong commercial interest
The collaboration with GreenSquareDC – a leading Australian data centre operator and developer focused on delivering sustainable, AI-ready infrastructure tailored for hyperscale and cloud clients – validates the strong commercial interest in VHD Graphite's potential as a next-generation thermal management solution.
It is also a key step forward in the company's ongoing customer qualification efforts, building on recent positive customer engagement and requests for application-specific sample testing.
'This is a truly exciting tangible step forward in our targeted customer qualification program and a strong indication of the rapid progress we've made in a short period of time,' managing director Clinton Booth said.
'This agreement validates the clear and growing market interest in VHD Graphite as a potential solution to thermal management challenges for data centres, AI computing and high-performance electronics.
'Building on the recent successful machining of our first prototype heat sink, and with a formal agreement now in place with a forward-looking, sustainability focused data centre operator and developer, we are demonstrating real capability to deliver a lighter, more efficient, sustainable and commercially viable alternative to traditional heat management materials.
'Through real-world testing and direct customer engagement, we are successfully proving the commercial viability of our innovative technology.'
