Invest in Airthium (YC S17): 100x cheaper battery to stop Climate Change | Wefunder
100x cheaper battery to stop Climate Change

Airthium Overview

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.
