Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

As the pressure to decarbonize electricity grids mounts, so does the need to have long-term storage options for power generated from renewables. While rechargeable batteries are the solution of choice for consumer-level use, they are impractical for grid-scale consideration.

ARPA-E awarding $30M to 12 hybrid solar projects; conversion and storage

Green Car Congress

Under the FOCUS program, projects will develop advanced solar converters that turn sunlight into electricity for immediate use, while also producing heat that can be stored at low cost for later use as well as innovative storage systems that accept both heat and electricity from variable solar sources. Earlier post.). MicroLink Devices.

New $30M ARPA-E program to develop new solar conversion and storage technologies; targeting higher solar penetration in mix

Green Car Congress

The high cost of grid electricity storage makes it best suited for high-value, short-term, frequency regulation; the lower value market for peak-shifted photovoltaic electricity is largely unprofitable, except where geography provides suitable reservoirs for lower-cost pumped-storage hydroelectricity. —DE-FOA-0000949.

BASF announces winners of the open innovation contest on energy storage

Green Car Congress

The winning concepts were: A molten air battery that uses a molten salt electrolyte at elevated temperature from Professor Stuart Licht at George Washington University. Sustainable technologies should make it possible to store power from the grid and feed power back into it.

Sadoway and MIT team demonstrate calcium-metal-based liquid metal battery

Green Car Congress

MIT professor Donald Sadoway and his team have demonstrated a long-cycle-life calcium-metal-based liquid-metal rechargeable battery for grid-scale energy storage, overcoming the problems that have precluded the use of the element: its high melting temperature, high reactivity and unfavorably high solubility in molten salts.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

The company is building these shipping container systems, which work like giant batteries that store energy as heat and pressurized air , rather than a chemical reaction (Cheesecake’s name is derived from a nerdy acronym for their technology.) The compressed air, now cool and easier to store, is housed in a large air tank.
