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

Green Car Congress

Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. The team previously reported a neutral molten salt reaction. of peak charge capacity. —Weller et al.

IPG to demo Flameless Ceramic Turbine for clean, off-grid power in EV charging

Green Car Congress

IPG’s project will demonstrate the role of Flameless Ceramic Turbine technology in bringing EV charging to high-use and remote locations through clean, cheap, grid-independent power generation. But, in many high-use areas and remote locations, upgrading grid connections to meet future charging demand is not practical or commercially viable.

BloombergNEF: solar, wind, batteries to attract $10T to 2050; curbing emissions long-term will require other technologies

Green Car Congress

Deep declines in wind, solar and battery technology costs will result in a grid nearly half-powered by the two fast-growing renewable energy sources by 2050, according to the latest projections from BloombergNEF (BNEF). Wind and solar grow from 7% of generation today to 48% by 2050.
