Interesting thing from another article on the company:
> GMG is an Australian-based clean-tech disruptive company listed on the TSXV (TSXV:GMG) that produces graphene and hydrogen by cracking methane (natural gas) instead of mining graphite
I wonder about the long term environmental impact of a technology that - at present - depends on continued fossil fuel extraction.

- Scoundreller 5y agoAnd it’s not like we’re running low on graphite deposits. You need a lot of gas to make a bit of solid. But maybe the process is better than direct combustion if you’re still able to use the process heat for something like district heating. Better to get the carbon sequestered in graphite instead of CO2.

- csours 5y agoIs graphene a greenhouse gas?
- labawi 5y agoBattery packs, car dashboards, your shopping bags as well as gasoline is made from oil, but only one of those is above 1% of world green house gas emissions. Creating graphene from gas instead of mining does seem cleaner, as methane can and probably will use green sources in the future. For NG -> graphene conversion, I don't see a problem, unless you're using it to smelt aluminum. OTOH, if batteries displace fossil fuel use, that seems like a huge positive, even with moderate amounts of aluminum smelting.
