H2: energy vector or source?
New Caledonia : the hydrogen released from the subsurface reacts with the CO2 in the atmosphere resulting in the carbonate precipitation. A natural carbon capture, utilization and storage (CCUS) process !
The dihydrogen presents obvious advantages : as a fuel it can burn without emitting greenhouse gases or particles and as means of storing electricity, it enables large scale and long period storage.
Today industry is mainly focusing its efforts concerning green H2 on reducing the price of electrolysis and fuel cells. This means that many companies are considering H2 as a vector. However, two game changers are emerging which could be very disruptive : natural H2 and H2 produced using plasma torching.
