The IRA is a breathtaking piece of government industrial policy. It impacts domestic mining and manufacturing, free trade agreements, and international trade in general because it is seen by non-free trade partners (like the EU!) as hugely protectionist, and thus maybe even illegal under international trade rules.
Its implementation may very well launch a trade war.
Even if modified, I suspect it will have a big impact on domestic manufacturing - mining is unknown because the other branches of the federal government, like the EPA, might continue to bog that sector down.
Also of interest is the government's
$2.8 billion Bipartisan Infrastructure Law. If you look at the 19 or so companies it showered $50M++ grants onto, most of them are moonshot battery technology stuff. These are mostly lab scale battery materials companies where 1 in 10 will graduate to economic industrial scale manufacturing. Many are private that are being funded by VCs. I mean, god bless the government for taking such risks, but wow, these are very early stage companies to shower with such large grants.
If the US doesn't end up with a quantum leap in battery technology from all this, you can't say the feds didn't try.
