This is a company that just recently hit the news (May 2022) mostly due to an article in the Economist. It’s a private company that developed out of the Cambridge University research hub. It was originally called Cambridge Nanosystems.
Its latest product is a self-contained processing plant inside a convenient shipping container. It converts methane, flare gas, into hydrogen and graphene. Usually flare gas is just burned off at resource extraction sites. Turning it into useful products while reducing CO2 emissions seems like a win-win-win situation.
