科學家如何希望透過鑽探活火山來拯救生命 (How scientists hope to save lives by drilling into active volcano)

 



冰岛这部分地区是


世界上最活跃的火山


热点。


克拉斯勒火山已经喷发了 30 次


1000 年前,最后一次爆炸发生在


20 世纪 80 年代。尽管


听起来很疯狂,科学家们现在


准备钻进去。


这个想法是为了更多地了解如何


火山的行为是为了让我们能够更好地


预测火山爆发,并


利用超热能源。


火山可能很壮观,但是


它们也具有毁灭性。


全世界有数百万人


靠近他们。在冰岛,居民


格林达维克的生活被彻底颠覆


通过一系列的火山喷发。


但这里的研究人员希望他们的工作


将改变这一现状,帮助拯救生命


和金钱,同时也是开拓者


一种火山力量。


我们有大约 40 口井分布在


地热场,产生


热水和蒸汽的混合物。


该电厂为大约


不久后,


50年前开始运营。


克雷夫勒开始清醒


又开始有火山了


距离火山仅两公里


我们现在所处的位置。这是一个


非常有力地表明


热量从哪里来?


利用这些新线索,科学家们开始


在这个地方钻孔


2009 年,他们偶然发现了


非凡的发现。


浅浅的岩浆袋。我们


目标是钻至 4.5公里


完全没有想到会击中


岩浆深度仅 2.1公里,


比


科学家们从未想象过。


熔岩产生的极高热量


摧毁了他们的装备。我们能够


测量来自


它,这个好。生产约10次


比平均水平更高


位置,给了我们非常强大的


极其


我们可能正在设置的强大资源


现在 A 队


来自 KMT 的Kraflow Magma


Testbed 项目想要找到它


再次。就在这里,2


几公里深的地方是一片炽热的


岩浆房和科学家们


准备深入钻探。


进入它。从


2026 年,他们将开始


第一个地下岩浆


天文台。我们基本上是站在


我们要钻孔的地点。


我们想要做的基本上是


彻底改变我们的监控方式


火山。我们计划在


岩浆、温度和压力


传感器。这将使我们能够预测


更准确地说是火山活动。所以


这将改变我们


预测火山爆发。


有了第二口井,他们将利用


极端高温,形成了


被称为岩浆附近


地热能。计划是钻探


距离岩浆本身仅一步之遥,


可能会用


地热资源,位于


就在岩浆体上方。我们认为


大约是 5 到 600 度


摄氏度。只有两个球洞


kind 可以匹配这个的输出


整个工厂。我们现在需要


为发电厂提供


22 口正常井。因此


明显的游戏规则改变者


并且还有令人兴奋的可能性


潜力无限、廉价、清洁


能量。这是我们生活的重要组成部分


将地热能带到下一个


水平,当然也占很大一部分


在绿色能源转型中。


但钻探在技术上


具有挑战性。在大学


冰岛,实验室工作正在进行测试


耐高温和


压力。这是碳钢,因此


地热使用的典型材料


这些碳钢材料


之后很快就失去力量


200 摄氏度,而且它们也不是


耐腐蚀。所以我们必须


探索新材料和更多腐蚀


耐高温合金。它们


工作温度高达 500


度和腐蚀性气体。


我们一直专注于高


级合金、镍合金以及


钛合金。


但还有一个问题


外面。这一切听起来有点


有点冒险。这样做安全吗?


这?我们认为,采取。针


进入一个巨大的岩浆房是不会的


产生爆炸性的效果。这发生了


2009 年,他们发现


可能之前做过几次


甚至都不知道。所以我们相信


它是安全的


我们的团队认为这可能是


世界各地都效仿。


关于浅层岩浆体的迹象


东非、美国和


夏威夷,可能就是这种。


地热发电可以


已应用于许多其他地点


在世界各地,我们积极


火山。所以这太疯狂了


听起来计划实际上可能有很大


潜在的。

---------------------------------

In this part of Iceland is one of the


world's most active volcanic


hotspots.


Crassler has erupted 30 times in


1000 years and last blew in the


1980s. And though it may


sound crazy, scientists are now


preparing to drill. Into it.


The idea is to learn more about how


volcanoes behave so that we can better


predict eruptions and also


tap into a super hot source of energy.


Volcanoes can be spectacular, but


they're also devastating.


Around the world, millions of people live


close to them. Here in Iceland, residents


of Grindavik have had their lives upended


by a string of eruptions.


But researchers here hope their work


will change that, helping to save lives


and money while also pioneering


a form of volcano power.


We have about 40 wells spread around the


geothermal field, producing a


mixture of hot water and steam.


This plant supplies electricity to about


30,000 homes soon after it


began operations 5 decades ago.


Kreffler began to wake up


again. We started to have volcanic


eruption only two kilometres away from


where we are standing now. This was a


very strong indication about where the


heat was coming from.


Using those new clues, scientists began


drilling in this spot where in


2009 they stumbled across an


extraordinary discovery.


Shallow pockets of magma. We


were aiming to drill to 4.5 kilometres


and were absolutely not expecting to hit


magma at only 2.1 kilometre depth,


much closer to the surface than


scientists ever imagined. The


extreme heat from this molten rock


destroyed their equipment. We were able


to measure the power that comes out of


it, this well. Produced about 10 times


more than the average well in this


location, giving us a very strong


indication of the extremely


powerful resource that we may be setting


up. Now A-Team


from KMT, the Kraflow Magma


Testbed project want to find it


again. Right here, 2


kilometres down is a red hot


magma chamber and scientists are


preparing to drill down.


Into it. Starting in


2026, they'll begin work on the


first ever underground magma


observatory. We are basically standing on


the spot where we are going to drill.


What we want to do is to basically


revolutionize the way we monitor


volcanoes. We plan to place sensors in


the magma, temperature and pressure


sensors. This will allow us to predict


with more accuracy volcanic activity. So


this will change how we


predict eruptions.


With the second well, they'll harness


that extreme heat, developing what's


called near magma


geothermal. The plan is to drill


just short of the magma itself,


possibly poke it a little bit with the


geothermal resource, which is located


just above the magma body. We believe


that is around 5 to 600 degrees


Celsius. Just two ball holes of this


kind could match the output of this


entire plant. We now today need


to feed the power plant with


22 normal wells. So there is


an obvious game changer


and there's the exciting possibility of


potentially limitless, cheap, clean


energy. This is a big part of how we are


going to take geothermal to the next


level and also of course a huge part


in the green energy transition.


But the drilling will be technically


challenging. At the University of


Iceland, lab work is underway testing


materials to withstand extreme heat and


pressure. This is carbon steel, so the


typical material used in the geothermal


wells. These carbon steel materials


lose strength quite quickly after


200 degrees Celsius and they're also not


corrosion resistant. So we have to


explore new materials and more corrosion


resistant alloys. They're


working with temperatures of up to 500


degrees and corrosive gases.


We have been focusing on high


grade alloys, nickel alloys and also


titanium alloys.


But there's still one question from the


outside. All this sounds just a little


bit risky. Is it going to be safe to do


this?We believe that taking a. Needle


into a huge magma chamber is not going to


create an explosive effect. This happened


in 2009 and they found out that they had


probably done this a few times before


without even knowing it. So we believe


it's safe


and the team here think this could be


replicated around the world. There are


indications about shallow magma bodies in


East Africa, in the US and in


Hawaii, possibly this kind of.


Geothermal power production can be


applied in many, many other locations


around the world where we have active


volcanoes. So this crazy


sounding plan may actually have huge


potential.
