US Unveils Plan to Triple Nuclear Power by 2050 as Demand Soars

[FBaggins]

* Biden White House aims to see capacity rise by 200 gigawatts
* President-elect Trump has offered support for new reactors

President Joe Biden’s administration is setting out plans for the US to triple nuclear power capacity by 2050, with demand climbing for the technology as a round-the-clock source of carbon-free power.

Under a road map being unveiled Tuesday, the US would deploy an additional 200 gigawatts of nuclear energy capacity by mid-century through the construction of new reactors, plant restarts and upgrades to existing facilities. In the short term, the White House aims to have 35 gigawatts of new capacity operating in just over a decade.

...snip...

The strategy is one that could win continued support under President-elect Donald Trump, who called for new nuclear reactors on the campaign trail as a way to help supply electricity to energy-hungry data centers and factories.

The nuclear industry — and its potential resurgence — also enjoys bipartisan support on Capitol Hill, culminating in the July enactment of a law giving the US Nuclear Regulatory Commission new tools to regulate advanced reactors, license new fuels and evaluate breakthroughs in manufacturing that promise faster and cheaper buildouts.

[Think. Again.]

1. Let's hope the fossil fuel industry runs out of money...

...to keep fighting against all of the non-CO2 emitting energy technologies.

Soon.

[FBaggins]

2. Not sure they're going to need to

It's far from ideal from an environmental perspective - but it works from an economic perspective.

The new administration wants them to "drill baby drill" and sell the stuff overseas. Less demand at home (shifted to nuclear) means more for export.

[Think. Again.]

3. The CO2 situation is global...

...so any reduction in emissions anywhere on the planet is good.

And yes, nuclear does have environmental drawbacks (at least until we figure out what to do with spent nuclear fuel), every ebergy production technology does have drawbacks, but those drawbacks are nowhere near as immediately and severely damaging as continued CO2 emissions.

12. OK, I'm convinced

How fast can you build this nuclear-powered paradise? Because we need dramatic change now.

We’ve got all sorts of exciting new plants in the design stage (they’ve been in the design phase for decades.) We had a go at small modular reactors (like monolithic reactors, it went way over budget, and way behind schedule, although this time it was eventually cancelled.)

17. France and China demonstrated that it can be very fast

But the plan laid out in the OP strikes me as being as optimistic as is plausible- and we will likely fall short

4. Meeting the new electricity demands of Artificial Idiocy, spyware, cryptocurrencies, etc., isn't enough.

Replacing ALL fossil fuel power plants with nuclear power plants ought to be our immediate goal.

The most environmentally destructive and potentially dangerous hydroelectricity plants need to be taken down too.

[FBaggins]

5. True enough... but only so much can be done in 25 years

It isn't just the herculean task of constructing hundreds of reactors when our recent experience has been years of delay... it's ramping up the education and training necessary to have the competent workforce to operate them.

I wouldn't be opposed to a plan that said we would continue at the 10-15 GW/year pace for a decade or two after that as well... but I think it would be near miraculous to hit that stride in the next decade

[hunter]

6. It could be accomplished quickly if we took the threat of global warming seriously.

Threatened by Imperial Japan and Nazi Germany we were able to transform the U.S.A. economy rapidly at the beginning of World War II. The threat of global warming is as dire or more so.

I hate to imagine what the U.S.A.'s "Pearl Harbor" of global warming will be, especially if it occurs under the Trump administration.

…

Present policies, with continued construction of coal-fired power plants without CO₂ capture, suggest that decision-makers do not appreciate the gravity of the situation. We must begin to move now toward the era beyond fossil fuels. Continued growth of greenhouse gas emissions, for just another decade, practically eliminates the possibility of near-term return of atmospheric composition beneath the tipping level for catastrophic effects.

The most difficult task, phase-out over the next 20-25 years of coal use that does not capture CO₂, is Herculean, yet feasible when compared with the efforts that went into World War II. The stakes, for all life on the planet, surpass those of any previous crisis. The greatest danger is continued ignorance and denial, which could make tragic consequences unavoidable.

…

(Your analogy was made more than a decade and a half ago. At this point, the task is much more difficult.)

11. Let's see, "Pearl Harbor" some dramatic event to wake people up

Nope…

7. Nuclear power is not green

No one has figured out what to do with the toxic nuclear waste. My engineer father with bachelors and masters degrees in engineering and more than 40 years of aviation and automotive engineering work experience taught me this.

[FBaggins]

8. Your engineer father can be forgiven his error

Not much aviation/automotive engineering involved in the debate.

Nothing is entirely green. This is the greenest non-malthusian path forward.

[OKIsItJustMe]

10. "greenest non-malthusian path"

If we could build nuclear plants that fast (I’m afraid we cannot) that will not release us from our “malthusian path.”

If we could eliminate all carbon emissions today, there is already far too much greenhouse gas in the atmosphere (“warming in the pipeline” to borrow a phrase.)

13. Your schooling and work credentials on this issue are?

It's the aviation and automotive engineers who will build the cars and airplanes that will run on hydrogen. It was part of my engineer father's job to know how every aviation and automotive fuel is formulated and refined from crude oil. My engineer father well understood that the world had to stop burning fossil fuels. My engineer father's original inspiration for realizing that green hydrogen is the solution was the space shuttle which ran on liquid hydrogen and oxygen?

[FBaggins]

14. Physics - and standing a watch or two on an LA class sub

Not saying your father wasn’t in a useful career - just not one that adds to a nuclear power debate.

Oh… and the space shuttle’s hydrogen came from fossil fuels and was “grey” at best. But you can get “green” hydrogen and oxygen from nuclear power if that’s what you want.

15. A minor quibble

Hydrogen produced by nuclear power is typically not considered “green hydrogen" since nuclear power is not renewable. That being said, nuclear power has long been considered a good way to produce hydrogen.

Here in NY, hydrogen is already being produced at a nuclear power plant at a demonstration scale.

Constellation Starts Production at Nation’s First One Megawatt Demonstration Scale Nuclear-Powered Clean Hydrogen Facility

State-of-the-art facility will demonstrate the value of producing hydrogen with carbon-free nuclear energy to help address the climate crisis

OSWEGO, NY (Mar. 7, 2023) — Hydrogen production has commenced at the nation’s first 1 MW demonstration scale, nuclear-powered clean hydrogen production facility at Constellation’s Nine Mile Point Nuclear Plant in Oswego, New York, an advancement that will help demonstrate the potential for hydrogen to power a clean economy.

When produced at scale, clean hydrogen can be used to make next-generation energy for otherwise hard-to-decarbonize industries like aviation, long haul transportation, steelmaking and agriculture. Last year, the US Department of Energy (DOE) approved moving forward with construction and installation of an electrolyzer system at Nine Mile Point with an award of $5.8 million.

“Hydrogen will be an indispensable tool in solving the climate crisis, and Nine Mile Point is going to show the world that nuclear power is the most efficient and cost-effective way to make it from a carbon-free resource,” said Joe Dominguez, president and CEO of Constellation. “In partnership with DOE and others, we see this technology creating a pathway to decarbonizing industries that remain heavily reliant on fossil fuels, while creating clean-energy jobs and strengthening domestic energy security.”

The clean Hydrogen Generation System operating at Nine Mile Point uses 1.25 megawatt of zero-carbon energy per hour to produce 560 kilograms of clean hydrogen per day, more than enough to meet the plant’s operational hydrogen use. It will also help set the stage for possible large-scale deployments at other clean energy centers in Constellation’s fleet that would couple clean hydrogen production with storage and other on-site uses.

16. True enough - I was using it the other way and was too cute

“Pink/purple” hydrogen is every bit as green as “green” hydrogen to me (and seemingly a rapidly growing majority). But I suppose that begs the question
