Submission Statement:

So a company called Cemvita Factory has developed a way to use bacteria to generate hydrogen in depleted and abandoned oil wells. Here's a select bit from the article:

>Cemvita Factory, a biotech firm in Texas, had spritzed a carefully selected combination of bacteria and nutrients down the bore hole. Once inside the well, the microbes began breaking down the residual oil hydrocarbons in there—dregs that would be unprofitable to extract—to generate hydrogen and CO2. This field test in July, though small in scale, was a “huge success,” says chief business officer Charles Nelson.

On one hand, the fact that they have proven the concept IRL, with tangible and measurable hydrogen generation in an existing oil well, bodes well. So many energy generation schemes never get off the paper they are written on (though they do get posted in this sub sometimes). On the other hand, they say this:

>Nelson explains that the firm’s goal is to treat oil wells with bacteria to enable steady, long-term hydrogen production—perhaps lasting for decades.

How do they know this is possible? Also, how is the CO2 generated at the same time dealt with; that's a huge issue. But beyond this, if we ever expect Hydrogen to become a significant source of energy, how do we get it from the production site to the end users? The Infrastructure for hydrogen is a huge and unanswered question. Can it just be pumped via the same pipes natural gas is transported in? Are all the gas stations going to be replaced by Hydrogen Stations? Do we really want the average driver handling hydrogen? All questions that we can discuss and theorize about.
