A 100% renewable energy world used to be impossible. Airthium designed a long-duration battery that is so cheap that it makes 100% renewables cheaper than coal, gas, and nuclear. A team with 2 PhDs raised a $500K pre-seed from Y Combinator, DCVC, and more.
Lithium-ion batteries are the only storage system that can be deployed economically anywhere today. They can store solar and wind energy, but they are limited and expensive — at $200/kWh, it only takes a few hours of discharge to deplete a lithium-ion battery.
Once depleted, recharging isn't always possible as it's not always sunny nor windy. Sometimes, such "droughts" can last weeks, or hundreds of hours. That's why we made a battery that can store 100x more energy for the same cost, at $2/kWh.
Did I Invest In Airthium?
I’m still in the process of writing a full deal report and decide whether or not I will invest in Airthium. I review 100+ startups on 10+ platforms every month and send a detailed report every Saturday to subscribers of the Angel Notes newsletter (you can join through the form below). See you soon!
