Prof. Yet-Ming Chiang and his colleagues are developing a new, inexpensive iron-air battery technology that could provide multi-day storage for renewable energy by 2024 through their startup Form Energy, reports Anuradha Varanasi for Popular Science. Chiang explains that “the battery can deliver clean electricity for 100 hours at a price of only $20 kilowatts per hour – a bargain compared to lithium-ion batteries, which cost up to $200/kWh,” writes Varanasi.
