ARPA-E Selects 37 Projects for $106M in Funding in Second Round; Electrofuels, Better Batteries and Carbon Capture

Green Car Congress

Electrofuels approaches will use organisms able to extract energy from other sources, such as solar-derived electricity or hydrogen or earth-abundant metal ions. from solar PV) to convert carbon dioxide into liquid alcohol fuels. This process is less than 1% efficient at converting sunlight to stored chemical energy. Electrofuels.

MIT team discovers new family of materials with best performance yet for oxygen evolution reaction; implications for fuel cells and Li-air batteries

Green Car Congress

MIT researchers have found a new family of highly active catalyst materials that provides the best performance yet in the oxygen evolution reaction (OER) in electrochemical water-splitting—a key requirement for energy storage and delivery systems such as advanced fuel cells and lithium-air batteries. —Grimaud et al. “We

Another attractive aspect of this technology is that lithium metal can be produced from salt solutions (e.g., In other words, energy from the sun can be “stored” in the metal, and then be used on demand by reacting the lithium in the fuel cell. Recharging the battery would be a matter of replacing the lithium metal cell.

wind and solar). In some studies it has been noted that the adequate BEV range perceived by the customer could be lower if the recharging time would be sufficiently short. For a 100 mile-range BEV requiring ≈21 kWh net , complete recharge could be accomplished within ≈60 min. Source: Gröger et al. Click to enlarge. kgH 2 /min.

Will the world run out of lithium?

Drive Electric NZ

Lithium is a naturally occurring element found in the earth’s crust and is usually found in mineral deposits, brine pools, and salt flats. Lithium is commonly used for rechargeable batteries, particularly in Electric Vehicles (EVs). LFP is an excellent technology for removing the reliance on cobalt.
