Comments on: Cornwall’s geothermal sites could also provide ‘green’ lithium for batteries https://www.newpower.info/2021/08/cornwalls-geothermal-sites-could-also-provide-green-lithium-for-batteries/ Expert information for all those invested in the UK's energy future Fri, 20 Feb 2026 08:08:27 +0000 hourly 1 http://wordpress.org/?v=3.6 By: John Daglish https://www.newpower.info/2021/08/cornwalls-geothermal-sites-could-also-provide-green-lithium-for-batteries/#comment-89081 John Daglish Wed, 18 Aug 2021 17:52:18 +0000 http://www.newpower.info/?p=10421#comment-89081 They could also run it through a membrane to generate electricity due to the high salt content of the water (higher than sea water) before extracting the lithium, see Salt Power
http://www.saltpower.net/

So co-generation – electrical power and
heat (for homes, business, etc. ) via District Heating network
then more electrical power generation via salt gradient
then lithium (and other rare earths) extraction
