iGii raises £12M Series B to scale lab-grown carbon nanomaterial for energy storage and manufacturing

Scottish deep tech company iGii has raised £11.7 million in a Series B led by the Scottish National Investment Bank, with PXN Group and Archangels also participating. Scottish Enterprise added £11 million, bringing total new backing to £22.7 million. The company makes Gii, a carbon nanomaterial that is grown rather than mined, for use in sensing, diagnostics, energy storage, and industrial manufacturing. The funding is meant to push Gii from early development toward reliable industrial-scale production. iGii says the material could help manufacturers differentiate products and reduce reliance on concentrated supplies of critical materials like platinum and gold. The round is roughly at the 54th percentile for its class, a solid but not outsized raise. For anyone tracking low-carbon industry and supply chain risk, this is a useful data point. The material has potential in energy storage, but the announcement is light on specifics about production capacity, cost per unit, or which manufacturers are actually testing it. Those details will matter more than the headline number.

Interesting raise. £22.7M total for a carbon nanomaterial company, but the press side is short on what Gii actually replaces in energy storage. If it's a drop-in for platinum or gold in electrodes, that's a bigger deal than the funding number.

Exactly. Grown carbon nanomaterials pop up every few years with big claims. What matters is whether it holds up at production scale and what the cost per kilogram looks like. No mention of pilot customers or capacity targets here, so I'd wait for actual specs.

The material sovereignty angle is the real story. If this cuts demand for mined platinum and gold in industrial processes, that has a supply chain and emissions angle. But 'grown rather than mined' needs more detail on energy input and yield before calling it green.

Agreed. The UK industrial strategy money is about reducing import exposure, not necessarily carbon. If iGii wants climate relevance, they need to publish lifecycle data. Otherwise this is an advanced materials play with a possible storage angle, not a decarbonization story yet.
