“Len told me that when the reservoir at Northfield Mountain is pumped full of water, it can be used to power about a million homes for eight hours.”

“Of the energy that it takes to run all the pumps and stuff at Northfield Mountain, they get about 75% of it back.”

“We are not investors in pumped hydro storage in the moment. We are not investors in compressed air energy storage. We are investors in a company that does thermal storage, storage as heat, albeit not molten salt. So we're investors in a company called Rondo En…”

“Well much as I love pumped hydro storage I just realistically don't think we're gonna add a whole lot more of it, certainly here in the U.S., so I'm not gonna put any of my money into that solution, though it is probably the most mature and maybe the cheapest,…”

“If you were again to compare that to primary energy supply, we have about nine minutes worth of pumped hydro storage, which means we have probably, I don't know, in the seconds level of battery storage capacity today.”
