Once the energy storage demand follows the PV exponential curve a little longer, it will be obvious to everyone that batteries won't cut it, and you will see people starting to deploy stuff like hydrogen electrolysis and liquefaction for storage combined with hydrogen fired gas turbine powerplants. Several of the established players are close to achieving dry-low-NOx 100% hydrogen gas turbines. Then you are talking about >500 MW power per unit and a thermodynamic efficiency of >65%. If you are in the "extremely abundant but too variable renewable power" scenario, these things will be the major stabilisers. You can easily imagine smoothing out even seasonal fluctuations with them. |
