More hydrogen research

In connection with fuel cells, I just wanted to share these new R&D breakthroughs on hydrogen production.

The green blog mentioned this week about producing hydrogen using sewage feedstock but according to researchers from the US Department of Energy’s Argonne National Laboratory and Ontario, Canada-based Kingston Process Metallurgy Inc. (KPM), you can also extract pure hydrogen from the hydrogen sulfide that naturally contaminates unrefined oil including oil sands.

Their innovative molten copper reactor not only extracts pure hydrogen, the researchers said, but it also produces another valuable chemical, concentrated sulfuric acid, which has become a high-priced commodity in the agriculture sector.If somebody wants a biotech-based hydrogen production, the US Department of Agriculture (USDA) might soon find a way to produce hydrogen from nitrogen-fixing bacteria. USDA scientists said they have developed a way to identify strains of these bacteria that produce hydrogen gas.

For now, making the current hydrogen production system more efficient is what California-based QuantumSphere is offering. Electrodes coated with the company’s Nano NiFe catalysts can reportedly accelerate the production of clean hydrogen in electrolysis systems by 300 times. The company said production of hydrogen through electrolysis had been hindered by high-cost catalysts and low efficiency.

    IMO, the hydrogen from H2S is a significant development. The classical Fischer process for producing hydrogen from H2S is very complicated. We need to note that although the amount of H2S in syngas on a % basis is quite low (~0.1%), large volumes of syngas (order of 1 million Nm3/h) of syngas are handled in industrial gasification plants. This means that the sulfur production rates are of the orders of several tonnes/d of sulfur.

    More info about various methods to produce hydrogen from H2S can be found in an article The use of sulfur to extract hydrogen from coalby Armando Jusino and Harold Schobert (requires subscription).

    Since we have allot of H2S coming out of Ras Laffan Feild in Qatar. I came up with this Chemical reaction equation (“Balanced”) as following:
    H2S + 4H2O ===> H2SO4 + 4H2
    and we are going to have this proceess equation as a patent of RasGas from now on as it seems that no one had think about befor we do in RasGas
