Solve for X: Danielle Fong on economical energy storage

Lightsail Energy: Economically competitive storage — hmm…? We watched Danielle’s presentation last night. Aside from the SMR companies, this is one of the “green energy” startups that looks interesting. The investors are certainly sophisticated in this space: Khosla, Gates, Thiel+Founders Fund, TOTAL, et al.

We will be poking around to see if there is any supporting evidence exposed to the public. Danielle talked about thermal efficiency but not a word about economics. She says they have a “utility scale” pilot running that is accumulating data. What we care about is the market price of a MWhr of energy delivered into the grid. You can figure the input costs at nearly zero as there is throwaway excess intermittent, esp. wind at night.
