Hello World.

Im so happy to introduce you all to GenX, a free open source optimization model for investment planning in the power sector, developed by the @MITEnergy Initiative & @Princeton ZERO Lab!!

Beta v1.0.0 out now!

energy.mit.edu/genx/
github.com/GenXProject/Ge…
GenX is a highly-configurable, open source electricity resource capacity expansion model that incorporates several state-of-the-art practices in electricity system planning to offer improved decision support for a changing electricity landscape. genxproject.github.io/GenX/dev/model…
Some backstory: GenX was originally written by @nsepulvedam & I during our graduate studies @MITEnergy/@TppMit/@mitidss. We each needed a planning model for our research & rather than each build a 'single-purpose' tool, we joined forces to develop a flexible model w/lots of uses!
Since then, the model has grown and evolved, and has been used by more than a dozen researchers @MIT and @Princeton for numerous peer reviewed publications, research reports, theses, and more. See energy.mit.edu/genx/#publicat…
Think of GenX like a Swiss army knife for electricity planning, chock full of features & advanced resources (like long-duration storage, flexible demand etc). Like a Swiss army knife, you can't use every tool at once (due to CPU limits), but you can use GenX for numerous tasks.
From a centralized planning perspective, the GenX model can help to determine the investments needed to supply future electricity demand at minimum cost, as is common in least-cost utility planning or integrated resource planning processes.
In the context of liberalized markets, the model can be used by regulators and policy makers for indicative energy planning or policy analysis in order to establish a long-term vision of efficient market and policy outcomes.
The model can also be used for techno-economic assessment of emerging electricity generation, storage, and demand-side resources and to enumerate the effect of parametric uncertainty (e.g., costs, demand, policy decisions) on the system-wide value or role of different resources.
GenX is now actively developed and supported by a wonderful joint team @MITEnergy (led by @dhariksm) and @Princeton ZERO Lab (led by myself). The team has put in a heroic effort getting the model ready for widespread use. I'm so grateful for all of their ingenuity and work! 👏
For an overview of the GenX model, see energy.mit.edu/genx/

To download and get started with GenX, head to github.com/GenXProject/Ge…

For full documentation and introduction to the model and its capabilities, see genxproject.github.io/GenX/dev/
GenX is in 'public beta' release here, and there's surely bugs, kinks, unclear documentation/instructions, etc. that will turn up. So if you're using it, please give us a holler on bugs/improvements etc! And feature requests. There's lots of features in the works. Stay tuned!
Finally, special thanks to @ARPAE FLECCS program (@ScottLitz program director) for financial support to open source this model and staff its user and contributor community!

Support from multiple @mitenergy & @Princeton ZERO Lab projects also contributed to GenX development.

It's official: Biden will commit to reduce US greenhouse gas emissions 50-52% below 2005 levels by the end of the decade. He'll make the commitment at 8am EST today as the virtual climate summit with world leaders kicks off.
nytimes.com/live/2021/04/2…

#ClimateAction #EarthDay2021
This goal is almost double the commitment the Obama Admin set for 2025 (25-28% below 2005) and requires accelerating the pace of emissions declined observed over the last decade. See below for progress to date (via @rhodium_group). 2030 goal requires ~3,200 MMT CO2 equivalent.
Making this goal a reality will require steep reductions in fossil fuel use across all sectors.

We'd have to virtually eliminate coal from power generation by 2030, ramp up clean sources (to more than double today's share), and cut electricity emissions to 75-80% below 2005.

Uniper is planning a 'hydrogen hub' in Wilhelmshaven, Germany, w/ammonia import terminal, 410 MW electrolyser, and regional H2 transport network: gulfenergyinfo.com/h2tech/news/20…

The America Jobs Plan calls for 15 clean H2 demonstrations that could seed similar hubs in the US by the way.
Note that aammonia, or NH3, is a potential long-distance carrier of H2. Hence the import terminal and proposed 'ammonia cracker' in the Uniper hub plans.
Notable too: "In addition, Uniper is working ... to ascertain whether it would be feasible to build a direct reduction plant w/upstream H2 electrolysis on the site of the existing power plant in Wilhelmshaven, as well as the required infrastructure for supplying raw materials."

The more I sit with the 25-page overview of the Biden #Infrastructure & #JobsPlan, the more it's clear: the measure of a plan is not the total $ it spends but its impact. There is a lot in this plan that isn't clearly scored w/$ figure. But the total impact looks transformative.
This #JobsPlan presents a vision for how to rebuild the U.S. economy. That vision clearly places at its center a set of investments to build a clean energy economy, enhance resilience to climate change & extreme weather, and address persistent environmental injustices.
Why do I say the #JobsPlan's clean energy investments look transformative?

My group at Princeton will be taking a close look at the plan & modeling its impact in coming weeks (as details become clearer), but let's take a first look at this thing together whitehouse.gov/briefing-room/…

*Very Biden voice* Folks, here's the deal:

At ~$1 TRILLION in total clean investment, what Biden is proposing in #JobsAct is not just bigger than clean investment in the Recovery Act of 2009 (~$90b), it's bigger than the ENTIRE Recovery Act (~$831b)!

Details #EnergyTwitter ⤵️
The White House Fact Sheet here details more than $550 billion in what we can classify generally as clean investment, incl:

$174b for EVs
$165b for public transit & rail
$100b for grid
$46b for clean energy manufacturing
$35b clean energy RD&D
& more: whitehouse.gov/briefing-room/…
IN ADDITION, @washingtonpost reports "The plan will also include approximately $400 billion in clean-energy credits on top of the $2.25 trillion in new spending."

That takes the total clean investment in the American Jobs Act to >$950 billion.

#ClimateAction is embedded throughout the 'American Jobs Plan,' including over $500b in what could be described as 'clean investment.' That's more than 5-times larger that the 2009 Recovery Act's spending on similar areas for context. An overview: nytimes.com/interactive/20…
The plan would invest:

$174 billion in incentivizing electric vehicle manufacture and purchase, building half a million charger stations

$85b for public transit investments

$80b for modernizing Amtrak and freight railways
$100b to build a more reslient electric grid & expand transmission to harness renewable energy

$46b for clean energy manufacturing

$46b for fed govt to procure fleets of EVs

$35b for 'climate technology' R&D

$16b for fossil workers transition

$10b for Civilian Climate Corps
