Excited to share our new paper where we explore #hydrogen supply & demand within energy transition scenarios limiting warming to 2°C and 1.5°C doi.org/10.1021/acs.es… Special thanks to co-authors Mignone, Kyle, Chapman, Fuhrman, @PaulWolfram2, and @HMcJeon 1 /6

New research on EPA’s finalized power plant greenhouse gas standards📣 A new nine-model study in @ScienceMagazine found the @EPA's power plant rules could reduce U.S. power sector carbon emissions by 73-86% by 2040, compared to 60-83% without the rules: science.org/doi/10.1126/sc…

What role could carbon management play in reaching net-zero emissions? Our new multi-model paper looks at carbon capture and carbon removal in U.S. net-zero CO2 by 2050 scenarios.

A new @CtrGlobSust-led study in @sciencedirect finds that meeting net-zero CO2 targets by 2050 will require rapid and deep changes to the U.S. energy system, with the power sector needing to expand by up to 190 GW/year in the 2040s. doi.org/10.1016/j.egyc…

@HMcJeon @nworbmot I’ll swiftly inform Chick-Fil-A and Five Guys of your response

@Pat__ORourke @nworbmot Meat is murder. Chicken is burglary. Milk is petty theft.

What flexibility do we need from biogas?🌱 Shifting baseload generation by a few hours with small storage helps, but what we really need is seasonal flex by upgrading to biomethane/ol (and using most of it in other sectors). A few thoughts on scaling, grids, liquids. 🧵

@HMcJeon @nworbmot Not where you were going with this, but couldn’t resist…

@nworbmot What of fugitive biomethane?

We can achieve #netzero #CO2 #emissions with or without hydrogen. But did you know? It'll be A LOT cheaper (up to 22%) with #hydrogen! Read more in the latest issue of @OneEarth_CP: sciencedirect.com/science/articl… @Pat__ORourke, @HMcJeon, Jay Fuhrmann, Page Kyle

🌏NEW PAPER🌏 “The hydrogen economy can reduce costs of climate change mitigation by up to 22%” published today in One Earth. Led by @PaulWolfram2 In collaboration with PKyle, JFuhrman, @Pat__ORourke and yours truly. 📄sciencedirect.com/science/articl… 🧵linkedin.com/posts/pwolfram…

🌎 New paper🌎 Finally, the paper you've all been waiting for: for once, GCAM modeling scenarios NOT relying heavily on CO2 removal, and instead reducing emissions everywhere else. 👇Thread by lead author Jay Fuhrman linkedin.com/posts/jay-fuhr… 👇Paper iopscience.iop.org/article/10.108…

I have been pretty silent on #AmmoniaFuel bashing lately.. In this new paper, the lead author @PaulWolfram2 convinced me that turning natural gas to ammonia and shipping it to Korea is not the WORST idea. (It is still a pretty BAD idea.) Read his post👇 linkedin.com/posts/pwolfram…

🚨New paper alert! lnkd.in/dyTp3HCSI How to decarbonize international #shipping ?🌍🛳 #hydrogen and ammonia are regarded as promising alternatives to current fuels. Turns out that their #decarbonization potential is highly uncertain though!❓🤷‍♀️Strict monitoring is key!🔑

🌍 Thread 1/8: Open Source Milestone 🚀 Exciting announcement: GCAM-China is now open source at github.com/umd-cgs/gcam-c…, a groundbreaking development in the IAM community, jointly supported by @PKU1898, @Tsinghua_Uni, UMD’s @CtrGlobSust. #OpenScience #ClimateAction #GCAM_Empire

Out for a field work counting whale CDR and brainstorming the new year’s new paper idea. @hausfath @Peters_Glen @Pat__ORourke @JayFuhrmanClimate: the meeting was supposed to be *in person* this year.

@HMcJeon You can call them “bridge” fuels for sale if you’d like

@HMcJeon For those that do think ammonia is clean, we’ve got liquid organic hydrogen carriers (LOHCs) to sell you

Clean energy I dislike: Ammonia Clean energy I begrudgingly respect: Large Custom Reactor Clean energy I think are overrated: Hydrogen Clean energy I think are underrated: Geothermal Clean energy I like: Solar
