The Long-Awaited Future of Fusion May Have Gotten a Little Bit Closer

At least that's what scientists at the University of Gothenburg may have determined. Science Daily has the story:
Ultra-dense deuterium is a million times more dense than frozen deuterium, making it relatively easy to create a nuclear fusion reaction using high-power pulses of laser light.

“If we can produce large quantities of ultra-dense deuterium, the fusion process may become the energy source of the future. And it may become available much earlier than we have thought possible”, says Leif Holmlid.

“Further, we believe that we can design the deuterium fusion such that it produces only helium and hydrogen as its products, both of which are completely non-hazardous. It will not be necessary to deal with the highly radioactive tritium that is planned for use in other types of future fusion reactors, and this means that laser-driven nuclear fusion as we envisage it will be both more sustainable and less damaging to the environment than other methods that are being developed.”
And how far are they in their discovery?
So far, only microscopic amounts of the new material have been produced. New measurements that have been published in two scientific journals, however, have shown that the distance between atoms in the material is much smaller than in normal matter. Leif Holmlid, Professor in the Department of Chemistry, believes that this is an important step on the road to commercial use of the material.

The material is produced from heavy hydrogen, also known as deuterium, and is therefore known as “ultra-dense deuterium”. It is believed that ultra-dense deuterium plays a role in the formation of stars, and that it is probably present in giant planets such as Jupiter.
Hope to see it work in our lifetime! Hat tip to JM.

When I first began researching nuclear power, over 30 years ago, fusion advocates said commercial fusion power was about 30 years away.

Today, fusion advocates say commercial fusion power is about 30 years away.

It's always N+30. Yet every time a fusion researcher puts out a breathless press release to get more grant funding, the media jumps all over it like we've landed on the moon.

It would be interesting to know the relative expenditures on fission research, a proven value, v fusion, a proven waste of money so far.

Making Clouds for a Living

Donell Banks works at Southern Nuclear’s Plant Vogtle units 3 and 4 as a shift supervisor in Operations, but is in the process of transitioning to his newly appointed role as the daily work controls manager. He has been in the nuclear energy industry for about 11 years.

I love what I do because I have the unique opportunity to help shape the direction and influence the culture for the future of nuclear power in the United States. Every single day presents a new challenge, but I wouldn't have it any other way. As a shift supervisor, I was primarily responsible for managing the development of procedures and programs to support operation of the first new nuclear units in the United States in more than 30 years. As the daily work controls manager, I will be responsible for oversight of the execution and scheduling of daily work to ensure organizational readiness to operate the new units.

I envision a nuclear energy industry that leverages the technology of today to improve efficiency…

Nuclear: Energy for All Political Seasons

The electoral college will soon confirm a surprise election result, Donald Trump. However, in the electricity world, there are fewer surprises – physics and economics will continue to apply, and Republicans and Democrats are going to find a lot to like about nuclear energy over the next four years.

In a Trump administration, the carbon conversation is going to be less prominent. But the nuclear value proposition is still there. We bring steady jobs to rural areas, including in the Rust Belt, which put Donald Trump in office. Nuclear plants keep the surrounding communities vibrant.

We hold down electricity costs for the whole economy. We provide energy diversity, reducing the risk of disruption. We are a critical part of America’s industrial infrastructure, and the importance of infrastructure is something that President-Elect Trump has stressed.

One of our infrastructure challenges is natural gas pipelines, which have gotten more congested as extremely low gas prices have pulled m…

Nuclear Is a Long-Term Investment for Ohio that Will Pay Big

With 50 different state legislative calendars, more than half of them adjourn by June, and those still in session throughout the year usually take a recess in the summer. So springtime is prime time for state legislative activity. In the next few weeks, legislatures are hosting hearings and calling for votes on bills that have been battered back and forth in the capital halls.

On Tuesday, The Ohio Public Utilities Committee hosted its third round of hearings on the Zero Emissions Nuclear Resources Program, House Bill 178, and NEI’s Maria Korsnick testified before a jam-packed room of legislators.


Washingtonians parachuting into state debates can be a tricky platform, but in this case, Maria’s remarks provided national perspective that put the Ohio conundrum into context. At the heart of this debate is the impact nuclear plants have on local jobs and the local economy, and that nuclear assets should be viewed as “long-term investments” for the state. Of course, clean air and electrons …
