A Mile Below Paris Drillers Hit Hot Pools To Warm Houses

Recommended Posts

http://www.bloomberg.com/news/2014-09-01/a-mile-below-paris-drillers-hit-hot-pools-to-warm-houses.html

In the midst of a suburban sprawl halfway between the Eiffel Tower and Paris’s busy Orly airport, a drilling crew works night and day burrowing deep into the Earth’s crust in search of underground heat.

The muddied workers from Cofor and Schlumberger Ltd. (SLB), an oil-services company that typically sinks wells in the deserts of Oman and deep waters off the shores of Brazil, will spend four months in Villejuif on the edges of the French capital. Perched on a towering rig, they will bore 2 kilometers, or 1.3 miles, under a tract of land wedged between low-income housing and the neat little white crosses of a local cemetery.

..

Now, as governments and companies around the globe develop renewable energy from wind and sun, they’re also looking at ways to capture naturally-occurring and always-available underground heat. French renewable energy represents around 14 percent of that consumed. The European Union has targeted 20 percent by 2020 for member countries.

I wonder how the UK will try and hit the 20% target.

I don't think we use Putin gas do we. Our problem is if England beat Norway.

Read somewhere that UK consumer end gas cost is 3x whoesale price. Reckon with those numbers most of europe could outbid us every day of of the year if the transportation routes were in plce to ship it.

Worth pointing out that there's nothing new about Paris drilling for hot water; they've been doing it for decades, see here for example.

What might be new is that new drilling technologies, cost of competing energy source, legal frameworks, etc... might be making it more interesting to drill down to what were previously considered 'marginal' hot water sources.

Shallow geothermal energy in the UK

Although the UK is not actively volcanic, there is still a substantial resource of geothermal energy at shallow depths but it is exploited in different ways. The upper 10–15 m of the ground is heated by solar radiation and acts a heat store.

This heat can be utilised by ground source heat pumps that can substantially reduce heating bills and reduce the associated carbon footprint. The heat from the sun is conducted downwards into the ground.

"A substantial resource of geothermal energy at shallow depths"

"Can substantially reduce heating bills".

That's probably why there's not much about it in the UK media.

Does not matter who we buy our gas from; the wholesale price will rocket as nations dependent on Putin gas compete with us.

Re-open the coal mines?

Wing it then complain about Europe when they somehow find they haven't met it. Finally, try and reclassify fracking or coal as renewable.

They've got a geothermal power station in the middle of Southampton, IIRC. It heats the port, the university, the council, some commercial buildings, and the mega-shopping centre.

There's nothing mysterious about ground source heat pumps.

They're not popular in Blighty because they're expensive. Especially to retrofit in existing buildings. For the average house, solar panels give you a bigger return at a small fraction of the cost.

They make a lot more sense in new-build housing. But even there they add to costs, which is never the British way.

It is odd, there is all this search for heat, yet, we are informed, the whole planet is a cooled crust on a sphere of molten iron.

Heat is down there. deffo.

So why not experiment getting at the Magma right under your Capital City?

Indeed there's nothing that mysterious about the energy source but as for relative cost that depends on the effects of peak oil on energy prices. The article by the British Geological Survey thought it could "substantially reduce heating bills" (on the basis of their sketch/diagram showing the energy going from the drill holes to large power station/generating plants feeding large areas rather than individual houses each generating their own). Perhaps it's like fracking hardly ever mentioned until the next day it's all over the newspapers and TV.

About the British Geological Survey

Founded in 1835, the British Geological Survey (BGS) is the world's oldest national geological survey and the United Kingdom's premier centre for earth science information and expertise.

The BGS provides expert services and impartial advice in all areas of geoscience. Our client base is drawn from the public and private sectors both in the UK and internationally.

Indeed...it'll eat into the profit/cost elsewhere...like the landowners.

At least with the US housing bubble prices doubled, but so did floorspace and amenities.

Here, if anything, houses get subdivided and shrink during bubbles.
