Cipher debuts Voices, a new section with articles from experts on topics important to reaching net zero by 2050. First: @JackieADowling @Caltech on why a broad portfolio of clean energy tech is critical to address all climate challenges: https://bit.ly/3KrFpjG
Linked in this paragraph: "Many utilities are now installing large arrays of lithium-ion batteries, similar to those used in electric cars, to help smooth over fluctuations in supply. But those batteries typically store electricity for just four to six hours at a time, which is insufficient to handle larger seasonal swings in wind and solar power. Some regions of the country can go days or weeks with little wind."
Citation #25. "For example, when renewable power in generated and unable to be used immediately, hydrogen can be produced from the excess renewable electricity and stored for days, weeks, or even months; making clean energy readily available from season to season."
On the Cover: Hydrogen split from water provides fuel for long-duration energy storage. In this issue of Joule, Dowling et al. find that long-duration energy storage (e.g., power-to-gas-to-power with hydrogen) can make reliable wind-solar-battery electricity systems more affordable.

As more states in the U.S. push for increased reliance on variable renewable energy in the form of wind or solar power, long-term energy storage may play an important role in assuring reliability and reducing electricity costs, according to a new paper published by Caltech researchers.
