We find that characteristics of high-cost hydrogen storage can be more valuable than low-cost hydrogen storage. Additionally, we show that modifying the freedom of storage sizing and component interactions can make the energy system 10% cheaper and impact the value of technologies. The results suggest looking beyond the pure cost reduction paradigm …

For example, if we have a system for hydrogen energy storage that has a roundtrip efficiency of 35 percent of so, the amount of electricity required to produce a kilowatt hour of energy output would be the inverse of that. So, one over to roundtrip efficiency would be the value that you will specify for amount of electricity feedstock required.
