CAs shifting regs THE REPUBLICAN CLIMATE PITCH: Assembly Republicans are taking aim at some of California’s environmental mainstays, from the California Environmental Quality Act to the Coastal Commission — and they’re calling it climate action. They unveiled a package of legislation today waiving environmental rules to fast-track the clearing of flammable vegetation around vulnerable communities and facilitate controlled burns. Assembly Minority Leader James Gallagher said climate change is exacerbating California’s wildfires by making forests drier but that California’s policies to reduce emissions aren’t enough to fix the problem.

this might be a win for biochar and pyrolysis in California? only if it requires that vegetation is not just burned in a big bonfire.

Not really practical to harvest vegetation for pyrolysis and biochar because of the vast areas involved. Hazard reduction burns are usually conducted in situ when weather conditions are favorable to a cool, controllable burn.

at what price per ton for carbon removed does it makes economic sense?

Carbon accounting is not my area of expertise but doing some AI assisted back of the napkin math suggests somewhere between $700-$1700 per ton CO2, depending on remoteness, difficulty of terrain and density of woody vegetation suitable for pyrolysis. You'd also probably still need to conduct the in situ hazard reduction burns, since herbaceous and grassy vegetation is not suitable for making biochar but can still form a ladder when dry that allows a scrub fire to become tree crown fire.

that's promising, right order of magnitude. industrial biochar is on the order of $200 per ton of carbon dioxide, depending on what if anything you can get for the biochar itself. There are companies like HUSK with custom processes designed for rice husks. What do you see as the biggest challenges with the grass portion?
