This makes sense given the reduced renewable capacity and, therefore, less renewable surplus. When further increasing the amount of shiftable electricity generation from bioenergy, however, the storage charging capacity re-increases, mostly due to additional hydrogen electrolyzers.
The storage charging capacity is about 72 GW, which is somewhat lower than the discharging capacity. Up to 161 GW of renewable surplus generation is curtailed because this is more economical than building more storage. Figure 1. Cost-optimal system configuration.
The 10-megawatt battery storage system, combined with the gas turbine, allows the peaker plant to more quickly respond to changing energy needs, thus increasing the reliability of the electrical grid. Power-to-gas is the conversion of electricity to a gaseous fuel such as hydrogen or methane.
In addition, our research found that under the proposed strategy, the cost of battery loss caused by cyclic charging and discharging is negligible compared to the discharge benefit. 1. Introduction
Optimal strategy for charging and discharging 4.1. Objective function Battery degradation will occur as a result of cycle charging-discharging , so the costs caused by battery degradation should be taken into account.
For hydrogen storage, which is decisive to bridge the largest energy deficit, the relative variation is less pronounced, but it should be noted that the absolute hydrogen storage volume is in the TWh scale while batteries are deployed in the GWh scale.

The lithium iron phosphate battery (LiFePO 4 battery) or LFP battery (lithium ferrophosphate) is a type of lithium-ion battery using lithium iron phosphate (LiFePO 4) as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. Because of their low cost, high safety, low toxicity, long cycle life and other factors, LFP batteries are finding a number o…
