NEOVIUX

NEOVIUX is a potential DTU Energy spinout building a compact fuel cell power module for tactical drones. The core is a monolithic gyroid SOFC, ceramic 3D-printed by Lithoz, with no metallic interconnects and no sealants. That simplification is what drives the performance: around 1 W/g power-to-weight, against 0.2 W/g for conventional planar stacks.

The module targets ~1 kW at under 5 kg, with system energy densities of 1,000–3,000 Wh/kg. For context, the Li-ion packs it replaces sit at roughly 250 Wh/kg and cap most tactical drones at one to two hours of flight. The module is fuel-flexible, so no hydrogen infrastructure is needed. A hybrid cold-start battery gets it to operating temperature in under three minutes.

The cell architecture was published in Nature Energy (Zhou et al., 2025) and is patent-filed. Current development focus is full module assembly and balance-of-plant integration. TRL 3–4. Commercial targets are defense and dual-use drone operators in the Nordics and Europe.
