UK-based HexSeed Technology, a carbon capture and utilization startup, has secured over €700k in early-stage funding led by Carbon13, with participation from the Net Zero Technology Centre and Vento Ventures. The investment will help the company transition its low-temperature diamond coating technology from lab demonstrations to working Gallium Nitride (GaN) devices.
Mark Tandy, HexSeed's CEO and co-founder, stated that data centres are set to consume a significant portion of UK grid capacity within a decade, and a large share of that energy is wasted as heat in power conversion. The company aims to address this issue by developing a thermal conductivity enhancement process using diamond coatings on GaN devices, which are crucial for powering AI-optimized facilities.
HexSeed is collaborating with the University of Bristol, specifically Professor Paul May and Martin Kuball, to create a low-carbon, low-temperature microwave plasma process that grows diamond coatings on completed GaN devices without causing damage. The startup plans to use the funding to demonstrate the coating process on commercial GaN power devices and pursue pilot customer engagements, with data centre power conversion hardware as the primary target market.
