Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Scientists have been looking for solutions in gravity energy storage , thermal or geothermal storage , and also molten-salt batteries. A recent study from the Pacific Northwest National Laboratory (PNNL) looks at molten-salt batteries that can “freeze” their charge for months until required.

New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

The new sodium-based molten salt battery uses two distinct reactions. The team previously reported a neutral molten salt reaction. The new discovery shows that this neutral molten salt can undergo a further reaction into an acidic molten salt. of peak charge capacity.

Nazar and her colleagues switched the organic electrolyte to a more stable inorganic molten salt and the porous carbon cathode to a bifunctional metal oxide catalyst. In addition, the superoxide consumes the organic electrolyte in the process, which greatly limits the cycle life.

The results showed 93.75% capacity retention after exceeding 4000 charge and discharge cycles. P Catalyst uses a molten salt carbon capture and electrochemical transformation method to reprocess the CO 2 -rich flue gases from heavy industry emitters, biogenic origin and even direct air captured (DAC) CO 2.

The Case for Nuclear Cargo Ships

Cars That Think

The European Union plans to begin charging shippers for carbon emissions this year. Researchers are considering three different types: a lead-cooled fast reactor, a uranium-fueled, helium-gas-cooled reactor, and a molten-salt-cooled reactor, shown here [below, at bottom]. One is a thorium-fueled molten-salt reactor.
