The continuous power though is actually quite minuscule in this context. NASA has a lot of test data published, e.g. for their 125 000 liter storage tank, the heat ingress in 24 h is 7.2 kWh while the energy content of the hydrogen in the tank is 290 000 kWh. What is being proposed for energy storage is signficiantly larger than this, and then the square-cube-law gives even less heat ingress as compared to the energy of the tank contents.
