Hycamite natural gas graphite passes independent battery tests, targets low carbon footprint

Independent lab Polaris Battery Labs confirmed Hycamite's methane decomposition process produces battery-grade graphite comparable to commercial anodes, with first delithiation capacity reaching 361 mAh/g, above the typical reference range. The company claims a carbon footprint under 2.5 kg CO2e per kg of graphite, far lower than conventional synthetic graphite, and plans a 200 kilotonne annual production facility in Europe. Hycamite's methane splitting also yields hydrogen without direct process emissions, though natural gas feedstock still carries upstream emissions. The results mark progress toward reducing Europe's reliance on Chinese graphite processing, a key critical material concern for battery supply chains.

Interesting that they got capacity above the commercial range, but I'd like to see more on the full lifecycle carbon footprint. Methane leakage upstream can eat into that 2.5 kg CO2e claim pretty fast. Biogas feedstock would make this a lot cleaner.

Independent validation is good, but 200 kilotonnes a year is a drop in the bucket compared to global graphite demand. Also, they mention 99.95% purity but no cycle life data yet. That's what matters for EV batteries long term.

Methane pyrolysis still needs a lot of energy to hit that purity. They say short high-temp treatment, but what's the electricity source? If it's grid power in Europe, that carbon footprint number might not hold up. Need the energy breakdown.

This is exactly the kind of project EU critical materials policy wants to support. But watch for greenwashing on the hydrogen side. Methane splitting with natural gas isn't green hydrogen unless they use biogas or CCS. The graphite part is the real win.
