Summary
Standard Thermal is a startup developing ultra-cheap energy storage technology that uses large piles of dirt to store heat from solar PV arrays. The system converts electricity to heat using embedded heating elements and stores it in dirt piles, with pipes running through to extract heat when needed. The goal is to make solar energy available 24/7 at prices competitive with natural gas by solving the seasonal energy storage challenge for solar power.
Key quotes
· 5 pulledStandard Thermal is the company I've been leading for the last ~2 years.
The purpose of Standard Thermal is to make energy from solar PV available 24/7/365 at a price that is competitive with US natural gas.
Our technology works by storing energy as heat in the least expensive storage material available - large piles of dirt.
Solar still needs storage cheap enough to move energy between seasons.
Electric heating elements embedded in the dirt piles convert electricity to heat.
