1. It's more expensive than standard cattle feed so it would need a subsidy to incentivize its use (probably a worthwhile investment for the Biden administration if they're serious about climate policy) and
2. there are some hurdles to massively scaling up the growth of the algae to supply the massive US cattle population.
(1) is interesting. I'm a big fan of a carbon tax over subsidies and direct govt intervention but this seems like an example of something that a tax would have a hard time incenting. I wonder if there are other examples like that.
Maybe a tax on cows but a rebate if they use this technology. But that seems like an easy system to game so maybe the direct subsidy is superior in this case.
