But almost all methane comes form natgas, no? I realize it is possible to make it from aneorbic fermentation, but almost none of that is in the market, being made by micro producers for their own use. Methane is a “stranded market,” not suitable for shipping long distances, so “renewable methane” tends to be consumed right next to dairy farms, feedlots, etc. where it is produced. > Disclosure: one of my clients is in the hydrogen industry. Disclosure: I’ve studied this in some detail, and have made bio-methane for cooking, which is most useful at low pressure — it takes as much energy as is in the methane to compress it to the ~500 torr necessary to have any driving range. If you have some references, I’d love to see them!
