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.

    Sadly almost all hydrogen currently making its way to market is dirty. I have high hopes for it in the future but it seems like thinly veiled poison at the moment.

    And this article is definitely about the dirty kind or at least feels like it is.

      There’s companies working on it! We’re just broke

      And yes, this is definitely the dirty kind. It may still be an improvement on using natural gas directly, but there would need to be a fairly comprehensive analysis to tell for sure. One possible advantage though is we could start building up a hydrogen infrastructure that we can then feed green hydrogen into and completely replace the dirty hydrogen.

      Anyway though, you’re right to be skeptical. It’s important though to look into the details to determine if it’s legitimately green energy or if it’s just oil companies greenwashing. We need to shun the latter while we promote the former.

      (There is a grey area, and it’s the same as electric cars – if we’re using electricity from the grid to power cars, and electrolyzers which make hydrogen, is it truly green? I would say this is acceptable for the same reason EVs are acceptable. It’ll become completely emission free once the grid is run on renewables.)
