Thanks, I was familiar with the general concept here, and specific companies working with methane, but not the electrolysis based companies. I had thought that wouldn’t be practical given the higher price of electrolysis hydrogen vs natural gas hydrogen.
A production cost of $5-$6 per kilogram of 100 percent protein. It aims to have Solein on the market and in millions of meals by 2021, but before then it needs to scale-up from pilot plant to major commercial production, and Solein needs regulatory approval for human consumption.
Claims like these are many times more common than delivery, but this seems interesting enough to be worth examining.
We found that the economics of hydrogen single cell protein could be promising in a catastrophe if it had low cost energy. Basically look at where aluminum refining is done-cheap hydropower or coal (which could have carbon sequestration).
Thanks for pointing out that paper. Yes, it does seem like some of these companies are relying on cheap hydropower and carbon pricing.
If photovoltaics keep falling in price they could ease the electricity situation, but their performance would be degraded in nuclear winter (although not in some other situations interfering with conventional agriculture).
