"A fuel pathway currently up for approval in California provides a great example of what’s happening. A run-of-the-mill hydrogen producer that generates hydrogen by reforming fossil natural gas from the gas grid has proposed purchasing environmental attributes from a large dairy farm generating biomethane from dairy manure…all the way in upstate New York. As the thinking goes, because that farm is no longer venting that methane into the atmosphere, and that methane is instead combusted into CO2, that farm should be credited for avoiding the powerful climate-forcing effects of methane. This means that anywhere in the country, if a farm can reduce its methane emissions from dairy manure beyond what is legally required and then pump that natural gas into the gas grid, it can be credited for that methane reduction under the LCFS as part of a 'book-and-claim' approach. This functions similarly to a carbon offset program, but without any requirements for demonstrating additionality. By purchasing the 'attributes' of the methane (i.e., ensuring that nobody else claims it), a hydrogen producer in California can therefore credit their fossil-derived hydrogen with the sizable credits from avoided methane emissions."

Just released! New work on the #LCFS, a little light reading on mathematical representations of emissions impacts from fuel displacement, perfect for curling up with over the holidays. Here's the short version (long version @ end of thread): https://escholarship.org/uc/item/7rf204xj 1/

A decade ago I scrutinized a gathering wave of 'advanced' biofuels for @nature (it's still one of my most cited works).
Today I'm back in Nature with a sober assessment of the R&D and smarter regulations required to put biofuels back on a socially + environmentally-beneficial path: https://www.nature.com/articles/d41586-022-03649-w
