Today Caltech researchers published findings showing that long-term energy storage solutions like hydrogen are needed to make renewable wind and solar electricity most cost-effective. The research, published in the journal Joule, looked at decades of data about wind and solar availability, and revealed that adding long-duration storage such as hydrogen to a wind–solar-battery system lowers energy costs.
Caltech’s data-driven approach is the first to incorporate four decades of historical wind and solar variability data, factoring in variability from year to year that affect power generation.
As California incorporates more and more renewables onto the electric grid, zero-carbon fuels will help make those renewables more affordable. I encourage you to read the story here.
