Three years ago, I published my projection of grid storage demand and solutions through 2060. At the time, various compressed gas electricity storage solutions such as compressed air, liquid air, and liquid carbon dioxide were in my also-ran technologies. My review of the literature over the preceding years had made it clear to me that they had intractable efficiency challenges and siting constraints, and as such wouldn’t scale.
But that was an outside view. Subsequently, I’ve been spending a lot more time on thermodynamics and operational requirements of solutions, and even a professional engagement assessing a compressed gas solution. Yes, they knew I was skeptical and STEM-oriented, and they wanted…
