Methane Pyrolysis: the third way for low CO2 Hydrogen production
Time: Thursday 27th February 2020, 10:30 am, followed by morning tea
Venue: Plant Research Centre Auditorium
In the context of global warming and necessary transition towards a less carbonized energy, Hydrogen will probably play a key role in the next decades. Unfortunately, the most current method for H2 production, often referred as “grey H2”: Steam Methane Reforming (SMR) is responsible, in average at the worldwide scale, for 11 tons CO2eq per ton of Hydrogen !
Water electrolysis is obviously an ideal long term option for the production of decarbonized H2 (“green H2”) assuming the use low carbon electricity. Unfortunately water splitting reaction is extremely energy intensive since it necessitates 285 kJ per mole (eq 1) which corresponds to approximately 40 kWh / kgH2 which makes the large scale development of this technology very challenging at short-middle term due to high production costs (around 6-4 US$, respectively for short and middle term).
H2O è H2 + ½ O2 285 kJ/Mole (1)
A third way which is today coming back on the front of the wave, often called as “Blue H2”, is based on the high temperature Natural Gas pyrolysis (eq 2) for the production of Hydrogen and solid carbon.
CH4 è C + 2 H2 75 kJ/Mole (2)
The main advantage of this approach is that is thermodynamically much less energy intensive than water splitting since it necessitates around 7 times less energy per mass (or mole) of H2 produced than water splitting. Another advantage is that it allows the co-production of two valuable product: solid (nanostructured) carbon and hydrogen respectively.
Researches on Methane pyrolysis by thermal plasma have been carried out at MINES-ParisTech for more than 25 years. The technology is now mature and a first commercial plant for the co-production of hydrogen and carbon black is today under construction in the US by MONOLITH Materials.
We’ll present in this conference, the state of the art on researches and technology in this field and discus on the potential of this technology at short, middle and long term.
