A new turquoise hydrogen demonstration plant — that makes hydrogen and solid carbon via methane pyrolysis — has begun operation in Finland, just under eight months since construction began.
However, hydrogen production at the plant will not be continuous at first, the company has told Hydrogen Insight, as it focuses its efforts on supplying customers solid carbon ahead of an expansion of its business into the US.
The turquoise production pathway makes hydrogen from methane molecules, heating them to temperatures upwards of 2,000°C in the absence of air in a special reactor in a process called methane pyrolysis. This process splits the molecules into hydrogen and solid carbon, or “carbon black”.
