Green Critical Minerals (ASX: GCM) is gaining international attention as it advances its VHD graphite technology towards commercial production. Green Critical Minerals focuses on developing graphitic and other mineral projects. The company is committed to supplying critical materials required for the global transition to a low carbon economy.
Recent finite element modelling commissioned by Green Critical Minerals on its VHD technology graphite heat sink has yielded significant results. The testing compared the heat dissipation performance of the VHD heat sink against conventional materials. Preliminary results indicate the VHD heat sink can substantially lower the operating temperature of high-performance microchips.
The tests showed that Green Critical’s VHD heat sinks can handle 300-to-400-watt power loads at microchip temperatures of 70 to 85 degrees Celsius. This significantly outperforms traditional materials, which typically manage only 200-250W. Managing Director Clinton Booth stated that VHD heat sinks consistently outperform conventional graphite, copper, and aluminium products.
Green Critical also sees potential for applying the VHD technology to other thermal management products, such as cold plates used in liquid cooling solutions. With these positive results, the company plans to increase customer engagement with global thermal management providers and semiconductor manufacturers. Green Critical anticipates a steady stream of updates throughout 2025, including customer advancements and initial sales agreements, with first revenue expected in the first half of 2026.
