Undecided with Matt Ferrell did a video with a mention of costs for some modern techniques a few days ago [1]. Levelized Cost of Storage (LCOS) per MWh: - CO₂

  First of all, these are almost certainly costs per Kilowatt hour, not megawatt hour. These costs would skyrocket if the world actually tried to deploy them at grid scale. The entire world only puts out 300 GWh of lithium ion batteries. By comparison, one hour of electricity storage is 2,500 GWh. You'd have to direct all battery Production to storage for 8 years, and pause the production of all EVs and electronics that use batteries. This drove the cost up above $500/KWh in New York for example: https://www.utilitydive.com/news/new-york-battery-storage-costs-rise-interconnection-queue-12-gw/621954/ https://www.utilitydive.com/news/new-york-battery-storage-co... Similar story with pumped hydroelectricity. You need the right geography to build pumped hydro. Most of it is in remote inaccessible places (Tibet has huge pumped hydroelectricity potential). The only economically viable sites are the ones that are close to transportation infrastructure. Once those are developed, the cost climbs as more and more remote sites need to be developed. Liquid air was promising, but the pilot plant took $600/KWh just to build. And who knows what the maintenance costs will be and if it'll live up to it's promised lifespan.

    And here I was thinking to have found a promising new YouTube channel. Thanks for the corrections.
