Correct. Plus losing methane fee would mean losing ~130 million tons of CO2-equivalent emissions (100 year global-warming potential as EPA inventory uses; a lot more if using 20 year potential). That's ~10% of the total House package's emissions cuts via repeatproject.org
EPA is restoring/expanding regulations on upstream oil and gas methane emissions and can make back up some (or all?) of these tons. eenews.net/articles/metha…
So perhaps the Biden Administration sees these as overlapping policies and therefore less critical to get over finish line?
Criticall, our REPEAT Project did NOT assume EPA regulations on methane were in place (as rules are still pending) when estimating impact of methane fee.
These kinds of losses show why a 'belt-and-suspenders' approach to climate policy is pretty key: e.g. reportedly losing methane fee but retaining strong EPA regulations, losing Clean Electricity Performance Program but (hopefully) retaining strong clean electricity tax credits.

.@SenJeffMerkley@SenWarren et al are taking issue w/subsidies for "blue" hydrogen saying we cant support "energy sources that could worsen greenhouse gas emissions." Good thing BBB makes H2 PTC explicitly contingent on lowering lifecycle GHG emissions! Here's how it works ⤵️
Merkley, Warren, Raskin, and other signatories are climate champions. But their attention/concern is misplaced here. Unless the House language is substantially altered, only hydrogen that lowers greenhouse gas emissions will get support.
Also, EPA is working on much more stringent regulations on upstream emissions of methane from gas supply chains, an area also targeted by methane fee in the House bill (which may or may not still be in final deal), so lifecycle emissions of blue H2 will drop as those go to work.
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.
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.
