Extracção de lítio em centrais de energia geotérmica

O lítio está cada vez mais caro e as fontes principais estão longe da Europa e dominadas pela China. Com o surgimento de tecnologia para extraír lítio das centrais de energia geotérmica, será de reanalisar as contas da energia geotérmica nos Açores ? Será que a composição dos fluídos dessas centrais é rica em lítio?

https://www.euractiv.com/section/energy ... from-2025/A geothermal power plant in the UK has discovered the highest concentration of lithium ever found in geothermal fluid, opening the door to a new business model for the renewable energy source.
Third-party tests carried out this summer revealed more than 250 milligrams of lithium – a critical metal for the green transition – per litre of the fluid used to transfer heat from under the Earth.
Once these are online, the company expects to extract 4,000 tonnes of lithium annually,
Law’s company is trialling zero carbon methods to remove the lithium from the fluid, and is currently capable of achieve extraction rates of 95%, he says.

could produce as much as 600,000 tons of lithium annually.
That is more lithium than the United States currently uses. It could bring in $7.2 billion a year, and that could just be the beginning of expected economic benefits. The global demand for lithium is expected to grow as much as tenfold by 2030.
