- et2o 7y agoWhy are batteries not scalable?
- new_realist 7y agoCost increases linearly with capacity, which is undesirable at scale. You want sublinear scaling. For example, to store a year’s worth of US electrical generation using batteries would cost approximately 500 trillion dollars.
- et2o 7y ago1) Huge number, but why would you need an entire year of energy in reserve 2) If there was a desire to build that many batteries, cost would surely decrease exponentially as new mines, factories, etc. open up and competition increases.
- inflatableDodo 7y agoBy definition, batteries are scalable. Battery is a word that defines a method of scaling. edit - For example; 'A battery of batteries of batteries of cells.'
- the_duke 7y agoYou should actually read the linked article. It's relatively sparse on technical details, but it does mention: - Renewable hydrogen - Compressed Air Energy Storage - Large scale flow batteries - Solid oxide fuel cells Seems like hydrogen is not actually used as a storage mechanism. They convert to hydrogen on demand to power turbines.
- new_realist 7y agoThey will be using sealed salt caverns to storage large quantities of gas cheaply.
