Berkeley Lab leading investigation to quantify and characterize Salton Sea’s geothermal lithium resources

Green Car Congress

There are currently 11 commercial plants at the Salton Sea field producing geothermal energy, a process in which hot fluids are pumped up from deep underground and the heat is then converted to electricity. We’ll look at how quickly might you expect the resource to be regenerated—is it centuries? Earlier post.).

Study finds high sodium bicarbonate concentrations in water from coal-bed natural gas production harms aquatic life; water treatment can mitigate effects

Green Car Congress

Produced water from coal-bed natural gas (CBNG) production may contain sodium bicarbonate (NaHCO 3 ) at concentrations that can harm aquatic life, according to a new study by the US Geological Survey; Montana Fish, Wildlife and Parks; the Bureau of Land Management and the US Environmental Protection Agency.

KAUST team devises electrically-driven membrane process for seawater lithium mining

Green Car Congress

An open-access paper on their work is published in the RSC journal Energy & Environmental Science. Seawater contains significant quantities of lithium—approximately 5,000 times more than is found on land—potentially providing an almost unlimited resource of lithium for meeting the rapid growth in demand for lithium batteries.

New liquid alloy electrode significantly lowers operating temperature of sodium-beta batteries; improved performance

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have devised an alloying strategy that enables sodium-beta batteries to operate at significantly lower temperatures. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire.

PNNL process extracts magnesium salt from seawater using laminar coflow

Green Car Congress

In the mid-20 th century, chemical companies successfully created magnesium feedstock from seawater by mixing it with sodium hydroxide, commonly known as lye. Generating pure magnesium hydroxide, without any calcium contamination, allows researchers to skip energy-intensive and expensive purification steps. —Wang et al.
