Germany says ‘yes’ to nuclear power in its backyard

An interesting item over on World Nuclear News reports that a Germany power utility, RWE Group, has acquired a chunk of a nuclear power station in the Netherlands. The story, Dutch nuclear plant to be 30% German-owned, describes “legal wranglings” that have been going on for a couple of years.

So, as Germany, ever hostile to anything nuclear, ponders unplugging its own reactors, can it, like the UK, where EDF Energy owns a large chunk of the electricity industry, look to a future when it imports nuclear electricity from foreign power stations?

Then again, if German consumers really do turn the idea of radioactive electricity, perhaps RWE’s customers in the UK will benefit from the company’s share in the Borssele nuclear power station.

The internationalisation of energy seems to pass over the heads of many. For example, someone asked to comment on something I had written on technology and climate change recently dismissed the idea that one day the UK might import electricity from solar power stations in the Sahara desert. I suggested that this could happen over the existing links to France, and through the planned European Electricity Grid Initiative, not to mention the recently opened BritNed cable.

I have no idea why the reviewer, probably an academic, dismissed the idea that the UK could receive renewable energy from Europe over a grid that is designed to carry renewable energy between countries in Europe. Then again, the same critic did not seem to realise that China is by far and away the world’s biggest supplier of rare earth metals.

Nuclear is an adjective – but don't tell the Royal Society

In its consultation document on the future of nuclear power, the Department of Trade and Industry (DTI) wisely avoids using the term "nuclear option". Even the overarching White Paper avoids the phrase, except when quoting a third party exercise.

The problem with the phrase is that you will find it used in many contexts to describe the most drastic option you can take, as in nuclear weapons. For example, the "nuclear option" crops up as a description in the Washington Post of the tactics used in the US Congress to block the president's nominations for top jobs.

It isn't, then, a good idea to use the term "nuclear option" when what you really mean is the option to build new nuclear power stations.

The same need for careful use of language should also acknowledge that the word nuclear is actually an adjective. Its origins are in the nucleus. Nuclear weapons and nuclear energy depend on smashing up nuclei. Nuclear magnetic resonance, the old name for magnetic resonance imaging before the "N" word fell out of favour, also depends on doing things with nuclei.

Someone should tell this to the Royal Society. This august body, the highest in the land, by its own reckoning, when it comes to science, has put out the inevitable statement in the wake of the White Paper.

In the Royal Society response to Government energy plans we read that "in the short to medium term nuclear could be crucial in helping the UK tackle the challenges of climate change and security of supply". Nuclear what?

Picky? Yes. But when you are dealing with opponents who like to hold up nuclear weapons as a reason for not using nuclear power it seems silly to offer them a hostage to fortune.

It takes very little to use the right words. If the DTI can do it, why not the RS?

Time to explode the hydrogen myth

The hydrogen bandwagon continues to roll. Only rarely does someone point out that this really is a case of the emperor with no clothes. So we must be thankful to Russell Seitz for chiming in with his piece At Last- A Genuine Hoax!.

Seitz hits the nail on the head with his observation that "hydrogen produced from H2O is a rare and precious commodity, costing a quarter its weight in silver because of the high price of American electrical power-- most of which comes from coal".

Hydrogen is just a carrier of energy. In this respect it resembles electricity. It is only a good idea if you need something to replace oil and gas in applications where you need a fluid that you can carry around.

In his attack on hydrogen from water Seitz misses reasons why hydrogen might have a role to play in a future energy system. Rather than turning coal into electricity to make hydrogen, why not get the carbon out of the coal and just use the hydrogen it contains? In that way you could tap the coal's energy without puffing CO2 into the atmosphere.

I leave it to others to calculate the thermodynamics of this idea. I raise it only because Lord Brown, the boss of BP, told me (links to a PDF file) that it is why the company is interested in hydrogen.

Another way to turn an "immobile" fuel into one that you can carry around is, of course, to use nuclear power as the source of energy for hydrogen creation. But once again the thermodynamics have to be right. And the sort of people who call for a hydrogen economy are almost certainly the last to contemplate the idea of building more nuclear power stations. They would rather see the lights go out all over the planet.
