Un proyecto geotérmico suizo queda paralizado por problemas técnicos
But the project has been suspended amid technical troubles in getting enough water into the 2,956 metre deep bore hole.
“Contrary to expectations the drilling operation has not produced a sufficiently powerful water flowrate to generate electricity,” the project organisers said on MondayExternal link.

Can deep geothermal projects help secure Swiss energy independence?
This content was published on
The climate crisis and the war in Ukraine have underlined the need to develop renewable energy sources like geothermal.
The project’s goal is to harness water that is heated to at least 110 degrees Celsius, with an ideal flowrate of 40 litres a second, to generate electricity. Deep underground the boiling point of water is higher than at ground level due to greater pressures.
It has been sited to tap into naturally occurring hot springs to create renewable energy.
But despite the setback, the company that runs the project, Alpine Geothermal Power Production (AGEPP), refused to concede defeat. It will conduct analysis to get to the root of the problem.

In April, Lyesse Laloui, head of the Laboratory of Soil Mechanics at the Federal Institute of Technology in Lausanne (EPFL) will host a meeting of world specialists in “energy geostructures” for a workshop that has the support of the American National Science Foundation. EPFL were the first to test in real conditions the behaviour of heat…
“All is not lost, because the temperature at the bottom of the borehole is good,” said AGEPP boss Jean-François Pilet. “We have proven that it is possible to dig 3,000 meters deep in an alpine massif of very hard rock. This is positive for further drilling.”
The technical issues at Lavey-les-Bains comes as Switzerland prepares itself for gas shortages this winter and is actively looking for ways to increase the share of renewable energy production.
In Lavey-les-Bains, however, tests “did not record the slightest seismic activity stemming specifically from the operation within its vicinity.”
