50:00 - "we can not do that in california. we dont have enough water" California is at the Pacific and many costal lines have steep rocks. But maybe you see some reason for rejecting salt water and also some reasonst for why your cliffs arent useable...

There are multiple pumped hydropower storage facilities in CA. Best known are Castaic Lake near Santa Clarita in So Cal and San Luis Dam near I-5 and the road to Gilroy. 2 more are In planning! However to date these are being used as part the projects which transport water to the more arid parts of state and not so much for balancing the duck curve

There are quite a few more dedicated pumped hydro storage facilities in California with more on the way.

50:57 What a joke, there is more than enough water in California for pumped hydro as generally the same water is used repeatedly. The efficiency for new dual speed pumped hydro is within 2% of the efficiency of large scale battery’s actual efficiency of 85% as documented by the roundtrip efficiency reported in federal filings. Large battery farm round trip efficiency is 85%. This can be directly derived from various forms that are filed. “Of the 150 plants (1,022 MW) that reported operating battery storage capacity on Form EIA-860 in 2019, 109 plants (850 MW) also reported electricity generation and consumption data on Form EIA-923 in 2019. These 109 plants reported a total of 458,169 MWh of gross discharge and 553,705 MWh of gross charge in 2019 (an average round-trip efficiency of 85%),”! Multiple new pumped hydro projects are in the planning stages. The only place that water has been a contentious issue is Eagle Mountain (for its initial fill). Generally the biggest problems are licensing, the relatively long construction time and the HIGH INITIAL COST.

Now all we need is some sleazy government officials to start selling sulfur credits.

+ticklewit I know ..right? I had to switch that shit off as soon as i heard him.

It's best if you double the speed - a hoot! *_:0)_*

[@FadahRon]

+ticklewit You and others who think you're funny should be watching cartoons or music videos. This stuff is far too intellectual for you.

I'm sorry but my Chinglish is not good enough and therefore it's too tiresome to follow this guy!

Too bad he can't speak english that I can understand. His accent is terrible.
