ARPA-E announces $12M for five projects in nuclear materials science; first OPEN+ cohort

Green Car Congress

The agency decided to create the OPEN+ cohorts—drawing from the large and impressive OPEN 2018 applicant pool—to focus on particular topics in energy where ARPA-E sees significant opportunities to innovate and create new communities. ARPA-E plans to announce a total of nine OPEN+ cohorts throughout late 2018 and early 2019.

Energy storage: the key to a decarbonised future

Setec Powerr

Technologies include energy storage with molten salt and liquid air or cryogenic storage. Molten salt has emerged as commercially viable with concentrated solar power but this and other heat storage options may be limited by the need for large underground storage caverns.

Researchers report advances toward room-temperature fluoride-ion batteries

Green Car Congress

However, current fluoride batteries use molten salt electrolytes, and thus need to operate at high temperatures. Jones (2018) “Room-temperature cycling of metal fluoride electrodes: Liquid electrolytes for high-energy fluoride ion cells” Science Vol. Rechargeable fluoride-based batteries could offer very high energy density.
