Nuclear Fusion News & Discussions

Post by Yuli Ban »

This Nuclear Reactor Just Made Fusion Viable by 2030. Seriously.
TAE Technologies, the world’s largest private fusion company, has announced it will have a commercially viable nuclear fusion power plant by 2030, which puts it years—or even decades—ahead of other fusion technology companies.
The California-based company has raised $880 million in funding for its hydrogen-boron reactor. This reactor isn’t a traditional tokamak or stellarator; instead, it uses a confined particle acceleration mechanism that produces and confines plasma.

All fusion technology has plasma, which mimics the extreme reactions that power all the stars—it’s what we’re emulating when we make fusion energy experiments. “Plasma is an oozy substance; the challenge of containing it is akin to holding Jell-O together using rubber bands,” TAE says on its website.

Another company to keep an eye on.

"Zap Energy is building the most compact, low-cost and scalable fusion reactor that does not employ magnets. Zap Energy achieved thermonuclear fusion in 2018 and is targeting scientific energy breakeven by 2023."

It's going to be incredible if they pull this off which is likely given the joint collaboration with an important U.S. Department of Energy agency to iron out the fundamentals of this technology.

Maybe after 2023, humanity will never know energy scarcity ever again.
To know is essentially the same as to not to know. The only thing that occurs is entropy.

Mast Upgrade: UK experiment could sweep aside fusion hurdle

8 hours ago

Initial results from a UK experiment could help clear a hurdle to achieving commercial power based on nuclear fusion, experts say.

The researchers believe they now have a better way to remove the excess heat produced by fusion reactions.

This intense heat can melt materials used inside a reactor, limiting the amount of time it can operate for.

The system, which has been likened to a car exhaust, resulted in a tenfold reduction in the heat.

[...]

The success of the exhaust system for Mast Upgrade delivers a boost to plans for a prototype fusion power plant in the UK called Step. It is expected to come online sometime in the 2040s.

China’s “Artificial Sun” Fusion Reactor Just Set a World Record
The reactor got more than 10 times hotter than the core of the Sun.

Is it hot in here, or is it just the fusion reactor?

China broke a record with its Experimental Advanced Superconducting Tokamak (EAST) fusion reactor on Friday when it sustained a plasma temperature of 120 million degrees Celsius for 101 seconds, according to the state-run outlet Global Times. The reactor was also able to sustain a temperature of 160 million degrees Celsius for 20 seconds.

For perspective, the core of our solar system’s Sun “only” reaches about 15 million degrees Celsius, according to Space.com. So, for a moment, EAST got more than 10 times hotter than that.

This marks a big milestone for the EAST reactor, which has been dubbed the “artificial Sun” for its ability to replicate the natural nuclear fusion process of stars. Doing so could help unlock the mystery to creating sustainable, reliable fusion power.

Nuclear energy: Fusion plant backed by Jeff Bezos to be built in UK

1 hour ago

A company backed by Amazon's Jeff Bezos is set to build a large-scale nuclear fusion demonstration plant in Oxfordshire.

Canada's General Fusion is one of the leading private firms aiming to turn the promise of fusion into a commercially viable energy source.

The new facility will be built at Culham, home to the UK's national fusion research programme.

The World's Largest Fusion Reactor Now Has the World's Most Powerful Magnet
The world's most powerful magnet, the "Central Solenoid," is finally here. At 59 feet tall, 14 feet wide, and 1,000 tons, the decade-in-the-making magnet is truly massive. Appropriately, it will soon find a home at the world's largest fusion reactor.
General Atomics completed construction of the magnet's first module earlier this year. Last week, the company began the process of shipping it off to southern France, where engineers will install it at the core of the International Thermonuclear Experimental Reactor (ITER), soon to be the world's largest fusion reactor if all goes to plan.

Helion passes 100 million degrees Celsius
Fusion energy developer Helion Energy said yesterday it has become the first private company to announce exceeding 100 million degrees Celsius in its sixth fusion generator prototype, Trenta. It also announced its Trenta prototype recently finished a 16-month testing campaign, completing almost 10,000 high-power pulses.
The company said reaching this temperature is a critical engineering milestone as it is considered the ideal fuel temperature at which a commercial power plant would need to operate.

The Case For Funding Fusion
by Albert Wenger
July 10, 2021

https://techcrunch.com/2021/07/10/the-c ... ng-fusion/

Conclusion:
(TechCrunch) Thankfully, there is a growing number of entrepreneurial efforts from world-class teams to try and build fusion. At least 25 startups around the world are targeting fusion right now, approaching the problem with a wide range of technologies. The amount invested in private fusion companies across the world increased tenfold to almost $1 billion in 2020, according to Crunchbase.

The upside of successful fusion is nearly unlimited. The clean energy generation market represents a trillion-dollar opportunity. An estimated 26 TW of primary energy capacity needs to be built globally from 2030 to 2050 to serve the rising global energy needs, according to Materials Research Society. Just 1 TW of capacity will generate $300 billion in revenue, and a 15% market share from 2030 to 2050 would yield more than $1 trillion in annual revenue.

We need many shots on goal here, which is why Susan Danziger and I have personally invested in three different fusion startups already (Zap Energy and Avalanche in the United States and Marvel Fusion in Germany).

But it is not primarily the potential for financial upside that motivates us: There is an opportunity to make an indelible difference in the trajectory of human history. If even a small fraction of the large wealth accumulated by entrepreneurs and investors in the last couple of decades is invested here, the likelihood of successful fusion rises dramatically. That, in turn, will unlock much more investment from both venture funds and governments.

Now is the time to go all-in on decarbonization. Funding fusion with its breakthrough potential must be part of that effort.
