Polar Night didn’t disclose the project’s cost, though the raw materials are cheap and the structure itself isn’t particularly complex. A much smaller prototype built a few years ago cost around $25 per kilowatt-hour of storage, the company estimated at the time. It’s likely the new version is cheaper. Lithium-ion batteries cost around $115 per kilowatt-hour.
“Economics look appealing”, but does not include costs.
- senectus1 1y agoyeah its not doing the project any favors is it.
- oliwarner 1y agoThey've only built two of these things in production. I think it's okay to use forecast costs when it's this early. I assume they'll get better at this, production gets cheaper and the bulk of the material will actually be a logistics cost rather than materials, so putting sticker prices on these might not translate well. But the "smaller prototype" is 8MWh. Their estimate of $25/kWh would make that $200k, and this 100MWh unit should scale to $2.5M but there have already received many times that in funding. Who knows.
