Skoltech researchers have found a way to produce hydrogen from natural gas with 45% efficiency right in the gas field by injecting steam and a catalyst into a well and adding oxygen to ignite the gas. Catalyst-assisted combustion produces a mixture of carbon monoxide and hydrogen, from which the latter can be easily extracted. This technology will help accelerate the transition from fossil fuels to clean hydrogen power. The study was published in Fuel.
What could possibly go wrong?
I’d be worried about the now excess co2 levels disrupting the normal saturation levels in the groundwater.
Sparkling water, on tap!
It’s what plants crave I guess.
This worst case scenario is probably the same as with any reservoir of natural gas (a massive leak and explosion), which is all the more reason to convert it to hydrogen and sequester the weaker, non-flammable GHG byproduct in situ.
I imagine that suddenly all the co2 stored as gas underground could suddenly come out and being odorless, kills the whole neighboring town
I mean, all that methane coming out would probably be at least as bad, and the cavity had previously been filled with methane.
It’ll be a cavern deep under a lot of rock. If it can contain methane for zillions of years, I imagine that it can contain carbon dioxide.
