My work on electricity decarbonization has demonstrated the importance of what I call "firm" low-carbon electricity generation technologies to enabling an affordable and reliable 100% carbon-free electricity system. See doi.org/10.1016/j.joul… & seminar
This work demonstrates that, under certain conditions, natural gas power plants w/CCS or burning hydrogen (possibly derived from methane reforming w/CCS) *could* play a firm low-carbon role in this 100% carbon-free electricity mix. THIS HAS NOTHING TO DO WITH GAS APPLIANCES.
The reason I focus my work on affordable & reliable paths to decarbonize electricity is that all efforts to build a net-zero emissions economy depend centrally on EXPANDING electricity use to REDUCE natural gas use for building heating & oil for vehicles:
In other words, my work is focused on paths that enable displacement of natural gas use for home heating and other applications as a key part of necessary efforts to build a carbon-neutral or net zero emissions economy. Exactly the kind of thing @CountyVentura is considering.
@SoCalGas cites my work in a misleading way to argue against the gas hookup ban. They seem to be trying to confuse @CountyVentura into thinking that because we can't immediately shut off existing gas power plants, they cant require new homes to be all electric. This is specious!!
My research is motivated by a desire to inform stakeholders and policy makers about effective paths to a net zero emissions economy. It therefore makes me very unhappy to see my work cited to confuse and likely mislead policy makers. So @SoCalGas: knock it off!
And @CountyVentura: please know that I do not endorse SoCal Gas's comments nor does my research argue against a transition to electric heating and cooking in residential buildings. Quite the opposite. If you have claryfing questions, please let me know.
They're right (with a few exceptions). Here's why...
We already have over 540 gigawatts of natural-gas fired generating capacity in the U.S. today. That's enough to meet about 2/3 of our nationwide peak in electricity demand. That's plenty of capacity to help manage the variability of weather-dependent wind & solar as they scale up
Those existing natural gas power plants will play a key role in the near-term as what I've termed "firm" generating capacity: available on demand (dispatchable), any time of the year, for as long as needed. (For more on firm generation, see doi.org/10.1016/j.joul…)
Here's 39 things President-Elect Biden could do to take #ClimateAction, featuring a round-up of voices from across the climate policy landscape: bloomberg.com/features/2020-…
My entry w/@CostaSamaras: appoint climate-focused Budget Director and White House Chief of Staff. Why? 🧵⤵️
President-elect Biden’s chief of staff and OMB director must align all federal agencies, spending, and legislative strategy around four big goals: ending the pandemic, rebuilding the economy, dismantling systemic racism, and confronting climate change. 1/
Cabinet secretaries get a higher profile, but no other positions beyond the President him or herself has a broader reach across the federal government than the Director of the Office of Management and Budget (OMB) and White House Chief of Staff. 2/
Wind, solar & battery costs have plummeted & energy storage installs are booming. Good timing for my new paper w/@dhariksm & @nsepulvedam on "Long-run system value of battery energy storage in future grids with increasing wind and solar generation"
Our new study out in @ElsevierEnergy's journal Applied Energy finds that the economic value of storage increases as variable renewable energy generation supplies an increasing share of electricity supply but that storage cost declines are needed to realize full potential.
We used a detailed electricity system planning model (energy.mit.edu/wp-content/upl…) to examine battery storage & determine key drivers that impact its economic value, how value changes w/increasing deployment over time, and implications for the long-term cost-effectiveness of storage.
In round #s: assuming electrification consistent w/net zero economy wide emissions by 2050, US needs ~5k-5.5k TWh of total electricity in 2035 (vs ~4k now). Need to ~double again by 2050 too! We have on order or 1.5k TWh from all clean sources today (about 1/2 nuclear & 1/2 RE).
So that says we need to more than triple all current carbon-free generation from now to 2035 to meet Biden goal. And we would need to build ~7 times current carbon-free generation cumulatively by 2050 to keep up with growing electric demand from EVs, heat pumps, electrolysis, etc
I'm a co-PI of @Princeton's Net Zero America study which is researching what it will take to get the US to net zero greenhouse gas emissions by 2050. We'll be sharing findings later this year on the scale and pace of this undertaking and the impacts on employment, pollution, etc.
A new ICE order from the Trump Administration out today may result in deportation of thousands of international students attending U.S. universities. Pure spite and racist hatred as policy. 😡 ice.gov/news/releases/…
As many universities (including mine) go partially or entirely online this Fall to continue their educational missions and contend with health risks of #COVID19, this new policy bars students on nonimmigrant F-1 visas from taking courses entirely online while residing in the U.S.
It simultaneously prohibits those in the U.S. from taking more than 1 class online while maintaining their visa status. In effect, this order forces students to take a full course load (less 1 online class) in person, whether that is safe or not, or to leave the country entirely
Im prepping my second to last lecture for 'Introduction to the Electricity Sector' -- on distributed energy resources & associated regulatory challenges. It's made me revisit the huge body of work published out of @MITEnergy Utility of the Future study effort...
I was so fortunate to be part of this effort, to learn from mythical figures in the field including Ignacio Perez-Arriaga (our fearless leader & my mentor), Dick Schmalensee, Bill Hogan, Paul Joskow, Michael Caramanis, Dick Tabors, Tomas Gomez, Carlos Batlle, and many more...
...and to get to spend 5 yrs thinking through regulatory challenges posed by growth of distributed energy resources with a crew of brilliant young scholars incl. @burgersb, Jose Pablo Chaves, Ash Bharatkumar, Pablo Duenas, Ignacio Herrero, Claudio Vergara, Sam Huntington & more.
