2023-01-17 Batteries Better Than Lithium Batteries
https://www.fastcompany.com/90761039 /these-rechargeable-batteries-are-more -sustainable-and-safer-than-lithium-and-half-the-cost Since lithium-ion batteries were first sold 30 years ago, they’ve dropped in cost by 97%. But they’re still too expensive for making electric cars that can compete in cost with fossil-fueled cars without subsidies, or to economically store wind and solar power on the grid. That’s why one Boston-area startup is developing

This is an interesting new old battery chemistry, developed to be rechargeable. And now the company is selling a storage system to a customer. https://pv-magazine-usa.com/2022/05/16/urban-electric-power-pine-gate-renewables-agree-on-multi-gwh-battery-supply-deal/
2021-08-17 Laser Hydride Film Stores Hydrogen
This company called Plasma Kinetics has developed a thin film that can store hydrogen at the same volume as a 5000 PSI cylinder but lighter, and lighter than batteries. The medium can be very thin film or disks. The hydrogen is released by shining a laser onto the film. Because the hydrogen does not have

2021-07-04 UEP’s BESS Lowers Costs $50/kWh
This is very interesting. A BESS that takes up less room than a lead-acid battery, can hold more kWh’s and is cheaper. They have a demo 2 MWh system in racks indoors. https://pv-magazine-usa.com/2021/06/30/urban-electric-powers-long-term-storage-solution-takes-battery-storage-back-to-the-basics/
2021-05-07 Relithiation To Make Old Batteries Like New
If the old cells were made easier to take apart and reassemble it would be helpful. I think that someday the battery makers may do what Eagle Picher did for batteries on spacecraft. There is a container of electrolyte inside the battery. To activate the battery a small charge blows the electrolyte out of the
