Iceland Seeking 'Supercritical Steam' For Power Source (bbc.com)

New submitter FatdogHaiku writes: Already getting over 25% of its electrical power from geothermal sources, Iceland hopes to break new ground using "supercritical steam" from a 5 km deep borehole. Is it just me, or does this sound like the start of a movie where everything that can go wrong does in fact go wrong? It's not like they are new to the tech, but working with geologic sources at 450C to ~600C is a new ball game for anyone. It should be noted that Iceland also uses direct geothermal for most of its space heating. "In this area at Reykjanes, we typically drill to 2km or 3km depth to harness the steam, to run power plants and produce clean, renewable electricity," explained Asgeir Margeirsson, CEO of the Iceland Deep Drilling Project (IDDP). "We want to see if the resources go deeper than that." The "supercritical steam" holds more energy than a liquid or a gas. The team wants to bring it up to the surface to convert into electricity, as they believe it could produce up to 10 times as much energy as the steam from conventional geothermal wells.

Re:anyone know..

[aliquis]

what kind of pipe they use for this kinda thing, im thinking some kind of ceramic metal hybrid?? Temps and sulfer corrosion must be a major PITA to deal with.

Thorium?
/ Swede.

See what I did there?
But I have no fucking clue.
Amazing Scandinavians. Utterly destroyed by treason from our ass-holes of politicians and the social-liberal left. WTF where you thinking?
I understand the concept: "It may bring problems if we talk badly about some people" - it's ok as long as you don't bring them here. But you know.. bringing Muslims into a nation and the poor into a welfare system isn't without consequences either.
