When Nuclear Fades

oldbury You don't get a very good result:

Power suppliers are turning back the clock to use coal-fired plants as their main source of electricity in a bid to avert potential shortages this winter.

Latest figures from the National Grid show that the fuel accounted for 42.5% of all power generation, overtaking natural gas production for the first time in years.

This is happening in Great Britain. Why?

The surge, from a usual level of little more than a third of total output, comes as the major networks seek to fill a gap caused by a slump in nuclear energy output at East Kilbride-based British Energy.

This is because a couple of plants are closed to have their boilers changed. That's the closing of two count 'em two plants that have caused this result.

It gets worse. If you've looked at the stories pointed to in the post about clean coal below, this next sentence will cause bitter and ashy laughter:

The major power companies stress that the increased use of coal is compatible with the drive for cleaner energy, and ScottishPower is investing heavily in "clean coal" technology at its Longannet and Cockenzie plants which could provide a quarter of Scotland's energy needs.

Now, we really, really want clean coal technology to work because a lot of people depend on it for their livelihoods. Having an industry collapse is not pretty - imagine, which you can now do, the American automobile industry completely shuttering and you have a sense, though on a global scale, of what a cratering (so to speak) of the coal industry would look like.

However, the clock is ticking. When it ticks, governments around the world have to find a way to expand their nuclear energy fleets before the current generation ages into obsolescence; when it tocks, they have to find solutions to the massive challenge of clean coal.

And if we really wanted to be alarmists about it, we'd have to add that we don't really know how many ticks or tocks are left in the clock.


Every time we read something about carbon capture and sequestration (CCS), it seems to represent a massive Catch-22:

A power plant equipped with a CCS system (with access to geological or ocean storage) would need roughly 10–40% more energy than a plant of equivalent output without CCS, of which most is for capture and compression.

On the one hand, you could use nuclear energy to supply the juice, but then again, you really don't need the coal plant if you've got the nuclear plant. Oops, that's another Catch-22!

The Oldbury plant, due to be decommissioned next year. Maybe they'll have that carbon sequestration thing worked out pretty soon. (Another nuclear plant is actually due to be built here, but that'll take time.)


And that's the bitter irony. Nuclear power plants need to start replacing baseload energy from coal power plants as soon as possible.

No new coal power plants should be allowed to be built anywhere.

Interestingly though, one nuclear plant dedicated to pulverizing olivine can take down the carbon from eight coal plants, somewhere else in the world, that -- even if you don't need them -- you've got.

NEI gets off message from time to time. No, I don't want clean coal (if ever there were an oxymoron, this would be it) to "work" because it will never rival nuclear power, and because burning coal must be relegated to the history books ASAP. I want the erosion and final collapse of the coal powered industry. That's creative destruction. That's technological progess: industries collapse, only to be replaced by better ones.

I do not think we need to take extreme positions. I hate the particulate matter and sulfur that comes from coal burning.But we have to live with coal as a major power source at least in my lifetime.
It shall be best if coal and nuclear power coexist and co-operate for least side effects. Steam or hydrogen from nuclear power can convert coal to gas which can be cleaned of particulate matter and sulfur (Mercury also where applicable) and to liquid fuel where necessary or desirable. Carbon dioxide is still under discussion. Gradually we can go to waste bio-mass (which is burnt off sometimes burning houses with it!) and convert it to gas and liquid fuel. We,our children and grandchildren can continue to use energy in an orderly manner.

Sneak Peek

There's an invisible force powering and propelling our way of life.
It's all around us. You can't feel it. Smell it. Or taste it.
But it's there all the same. And if you look close enough, you can see all the amazing and wondrous things it does.
It not only powers our cities and towns.
And all the high-tech things we love.
It gives us the power to invent.
To explore.
To discover.
To create advanced technologies.
This invisible force creates jobs out of thin air.
It adds billions to our economy.
It's on even when we're not.
And stays on no matter what Mother Nature throws at it.
This invisible force takes us to the outer reaches of outer space.
And to the very depths of our oceans.
It brings us together. And it makes us better.
And most importantly, it has the power to do all this in our lifetime while barely leaving a trace.
Some people might say it's kind of unbelievable.
They wonder, what is this new power that does all these extraordinary things?

A Design Team Pictures the Future of Nuclear Energy

For more than 100 years, the shape and location of human settlements has been defined in large part by energy and water. Cities grew up near natural resources like hydropower, and near water for agricultural, industrial and household use.

So what would the world look like with a new generation of small nuclear reactors that could provide abundant, clean energy for electricity, water pumping and desalination and industrial processes?

Hard to say with precision, but Third Way, the non-partisan think tank, asked the design team at the Washington, D.C. office of Gensler & Associates, an architecture and interior design firm that specializes in sustainable projects like a complex that houses the NFL’s Dallas Cowboys. The talented designers saw a blooming desert and a cozy arctic village, an old urban mill re-purposed as an energy producer, a data center that integrates solar panels on its sprawling flat roofs, a naval base and a humming transit hub.

In the converted mill, high temperat…

Seeing the Light on Nuclear Energy

If you think that there is plenty of electricity, that the air is clean enough and that nuclear power is a just one among many options for meeting human needs, then you are probably over-focused on the United States or Western Europe. Even then, you’d be wrong.

That’s the idea at the heart of a new book, “Seeing the Light: The Case for Nuclear Power in the 21st Century,” by Scott L. Montgomery, a geoscientist and energy expert, and Thomas Graham Jr., a retired ambassador and arms control expert.

Billions of people live in energy poverty, they write, and even those who don’t, those who live in places where there is always an electric outlet or a light switch handy, we need to unmake the last 200 years of energy history, and move to non-carbon sources. Energy is integral to our lives but the authors cite a World Health Organization estimate that more than 6.5 million people die each year from air pollution.  In addition, they say, the global climate is heading for ruinous instability.
