Energy storage technology is advancing, but there are certain flaws with current and next-generation battery technology; for example, current Lithium-ion batteries are flawed; they can only hold a charge for so long, but we also have no way of disposing or recycling them currently. Flow batteries have a similar problem as they can't hold a charge for long periods of time, making them useless in large battery farms. The only effective ones are hydrogen, and nuclear waste batteries, hydrogen as its constantly improving technology makes it a great solution for mass storage of excess energy; nuclear waste batteries are a potentially revolutionary technology phase 1, which is a more commercial and residential product that could power devices for long periods of time without charging phase 2 is a more powerful device which wouldn't be available to the residential or small commercial applications and would be more focused for space exploration this device could last up to 28,000 years on a single charge.
