To start: I'd love a $20/t carbon price from Congress. That said: given current political stalemate on the Hill, what political impasse does it solve that brings us closer to passage of Build Back Better? Honest question.
Manchin seems to want to minimize contraction of coal sector. Any meaningful price that hits power sector ($10/t or more?) could decimate coal. So it exempts power sector?
Both Manchin and Sinema seem to want a smaller package thats fully paid for. But a carbon tax used for general revenue would violate POTUS pledge not to raise taxes on the working class. So how does that square? Tax and dividend doesn't raise net revenues for other programs.
I just don't see it...

Great to have @MicahZiegler from @mitidss at @PrincetonSPIA today to kick off 1st Bradford Seminar of new semester & our 1st back in person. He integrates data, analytics & chemistry expertise to unpack clean energy tech cost & performance trends to accelerate their improvement.
Here's a good example of @MicahZiegler's work, with @mitidss's Jessika Trancik, "Re-examining rates of lithium-ion battery technology improvement and cost decline." pubs.rsc.org/en/content/art… (open access)
@MicahZiegler & I are both passionate about using our research to better target R&D effort, funding, and investment to accelerate innovation and improvement of critical clean energy solutions. We have limited time & limited resources, and we need to make them count!
Here is a section by section summary of what's in draft tax package from the House Ways & Means Cmte: waysandmeans.house.gov/sites/democrat…
(Part of it anyway, related to Infrastructure Financing, Green Energy, Social Safety Net, and Prescription Drugs)
First off, the clean electricity tax credits are now structured with strong incentives to pay good wages, train apprentice skilled workers, and use domestic produced iron, steel & manufactured content.
To get full tax credit values (referred to as "bonus rate"), projects must pay prevailing wages & use certain percentage of labor hours from qualified apprentice workers. Otherwise, tax credit value is only 1/5th of full value (referred to as "base" rate).
Reading legislation is NOT fun. Reading formulas in leg text is much worse (why cant we just use algebra?).
So here's a plain English (I hope) explanation of what the Clean Electricity Performance Program from House Energy & Commerce (Subtitle D: energycommerce.house.gov/newsroom/press…) says...
CEPP creates a grant program for suppliers of retail electricity that achieve a 4% year on year increase in the share of clean electricity used to supply their customers.
It also collects a payment from suppliers of retail electricity that fall short of 4% YoY ⬆️ in clean share
"Clean electricity" in this bill means any source of electricity that produces less than 0.1 tons of CO2-equivalent greenhouse gas emissions per MWh of electricity generated.
In short: to meet the cost & performance targets identified in our research, LDES techs need:
1. Ultra-low energy capacity costs (~$1-10 per kilowatt-hour the device is capable of storing) 2. Suitably high efficiency (particularly for discharge) 3. >100 hrs sustained discharge.
“This is a budget-based strategy as opposed to a regulatory-based strategy,” Sen. @TinaSmithMN on a Reconciliation-friendly Clean Electricity Standard that is part of the Budget framework agreed on by @SenateBudget Dems yesterday. More via @bstorroweenews.net/articles/payme… & 🧵
Broad contours of a Reconciliation-friendly Clean Electricity Standard (CES) are now coming into public view, as House & Senate Dems prepare a $3.5T Budget Resolution that will kick off a Reconciliation process, which permits passage of budget-related measures w/50+ Senate votes.
There are many important details to be worked out + negotiations must secure support of all 50 Senate Democrats to ensure passage, but Sen. @TinaSmithMN, who has championed this key clean energy measure, and a Budget Cmte outline of the $3.5T plan have revealed broad outlines...
DOE's new "Earthshot" aims to drop the cost of "long duration" storage 90% below cost of current Lithium ion batteries, the dominant grid storage option today, by 2030.
Lazard pegs cost of large 100s MWh scale Li-ion installations at $163-309/kWh so DOE target is ~$15-30/kWh.
And by "long duration", DOE means any technology technically and economically suited to >10 hours of sustained discharge.
Those targets for both duration and cost will move the needle, but based on our research, they are probably not aggressive enough.
