From bench chemistry to the open sea

I work at the point where science becomes industry. For fourteen years I have turned laboratory science into industrial ventures — and I now study and teach how that crossing is made. My current research turns thermochemical expertise toward one of the decade's most strategically urgent materials problems: battery-grade hard carbon for sodium-ion energy storage, made from European biomass residues.

The commercialization gap

If there is one idea that connects everything in this dossier, it is the distance between a technology that works in a laboratory and a product that survives in a market. My work is a sustained, hands-on investigation of that gap — not as a metaphor, but as a set of coupled, concrete barriers.

Barrier 01

Product development

Designing, building, and scaling the hardware and process systems that turn a laboratory proof into a repeatable industrial product. From bench-scale reactors to containerised pilot plants to full commercial facilities.

Barrier 02

Capital

Assembling equity, grants, and soft funding across the "valley of death" between proof and profit. I raised and deployed on the order of USD 25M across 15+ programmes.

Barrier 03

Certification

Meeting the standards that turn a product into a tradable, trusted commodity. ISO 8217 marine fuel, European Biochar Certificate, Puro.earth carbon removal, ISCC EU, RED II/III lifecycle rules.

Barrier 04

First-of-a-kind deployment

Getting a real customer to run the technology at real scale, with all the risk that entails. The world's first carbon-negative commercial vessel voyage, powered by fuel made from cashew-shell residue.

Barrier 05

FOAK lab and facility development

Building the physical infrastructure — labs, pilot halls, testing rigs, and production facilities — that a first-of-a-kind technology needs before it can prove itself. Designing for the constraints of where the technology must actually run, not where it was born.

Current focus

DTU BioNa — hard carbon anode materials from lignocellulosic residues for sodium-ion batteries

The energy transition needs enormous amounts of stationary storage. Lithium-ion dominates, but lithium and cobalt carry supply constraints and geopolitical exposure. Sodium-ion batteries have emerged as a leading candidate — abundant, cheap, evenly distributed. The bottleneck is the anode: hard carbon, a disordered, nanoporous carbon whose ability to store sodium depends intricately on its microstructure.

My current research applies a decade of pyrolysis and biomass-fractionation expertise to control that microstructure for electrochemical performance. The same core skill — turning variable biomass residue into high-value structured carbon — now aimed at the next strategically urgent application.
