Closed-loop pump hydro on the rise Emiliano Bellini 2021 Oct 01 pv magazine www.pv-magazine.com/2021/10/01/closed-loop-pumped-hydro-on-the-rise/Despite such studies, pumped hydro projects in the USA never manage to obtain funding. The existing one in California I know something about just barely makes its O&M, not even enough to save for the pump and generator replacements. ”All hat, no cattle” |

Here is the folly of the "renewables plus token storage" argument. Sooner or later the batteries go flat and the dams go dry. Then suddenly all the faithful are grateful that cautious planners have delayed the dismantling of fossil-fired infrastructure. At my end of the world, scenarios of a virtuous future are painted with renewables in bold, and at bottom a need for a small amount of gas is in fine print, unquantified. Although this is meant to read as if only a small amount of gas infrastructure would be required, in fact it would be a small amount of every day that requires the entire gargantuan gas infrastructure to be belching emissions at full blast. If renewables-plus-storage is to replace all energy usage across all contingencies of the weather, the storage must be sufficient to always exceed consumption. The only way I can see this happening is if a vast excess of renewables were dedicated to generating synthetic fuel. Traded for all non-electrical power, it could also be stockpiled against contingencies. The synthetic fuel would have to be manufactured cheaper than the fossil equivalent if it is to undermine its market. After all, all coal mines must be filled in and wells collapsed, worldwide. For some reason, the fossil fuel industry is not making much effort in that direction… Should I wonder why? That scenario would have an enormous cost on natural resources, consuming land area that should be either under agriculture or natural forest. Of course, they could just go nuclear instead. |
