Hydrogen is a poor storage medium, agreed. The rational seems to be that Portugal and Spain have periods when “renewable” energy generation exceeds demand. Hydrogen provides a means to store a recoverable fraction of that temporary local surplus.

if that’s the case, wouldn’t it be less expensive, safer, more energy efficient, and more reliable to simply build electricity transmission lines with tried and true technology instead of converting electricity to hydrogen via electrolysis, transporting it by nearly impossible to build and dangerous hydrogen pipelines, and THEN burning the hydrogen at the delivery terminus?
