A DTU pre-spinout project

Accelerating European hard carbon production.

With the world’s first carbon-negative battery material.

BioNa produces battery-grade hard carbon anode material from agricultural waste—the only fully European anode with a carbon-negative lifecycle.

The challenge

Europe’s battery supply chain has an anode problem.

Anode materials are the critical weakness of European battery supply chains. For sodium-ion batteries—identified by the EU as a strategic priority—hard carbon is the only viable anode material.

With no European producer and Chinese supply under CBAM pressure from 2027, cell manufacturers face a critical bottleneck. BioNa was built to solve it.

The supply chain gap

Every major battery chemistry depends on an anode.

Europe is investing across cathode chemistries while the anode layer remains overwhelmingly dependent on China.

The Double Negative process

Carbon negative.
Negative electrode.

Our proprietary process converts European agricultural biochar into high-performance hard carbon anode material for sodium-ion batteries.

Durable carbon sinkCarbon remains locked in the anode

The hard carbon stored in a battery anode can act as durable carbon removal under the EU Carbon Removals and Carbon Farming Regulation.

Technology

Designed around accessible pores.

BioNa’s proprietary multi-stage carbonisation precisely directs the evolution of carbon microstructure, synthesising hard carbon particles with optimised accessible pores.

These microporous structures enable sodium storage while limiting SEI formation—supporting specific capacity without sacrificing Initial Coulombic Efficiency.

DTU Energy capability

Rapidly tailored to individual feedstocks.

Through DTU Energy’s state-of-the-art material characterisation laboratory and electrochemical testing facilities, our analytical team can adapt the multi-stage process to individual biochar feedstocks and create bespoke treatments case by case.

Why BioNa

One material.
Three strategic advantages.

VP 01

Sovereignty

Every component of our supply chain—from agricultural feedstock to finished anode material—is sourced and processed within Europe.

100% European
VP 02

Sustainability

Our life-cycle assessment shows a carbon-negative process. The anode acts as a durable carbon sink under the EU CRCF Regulation.

Up to −1.8 kg CO₂/kg
VP 03

Efficiency

Biochar converts to hard carbon with a simpler supply chain, lower logistics costs and exceptionally high material yield.
