2021-09-05 Blue Hydrogen Is Greenwashing By Big Oil
At 13:00 Dave talked about how problematic green hydrogen is, and at 13:30 he said why not just use the electricity directly for the home. Herein is the whole problem: the solar and wind electricity is generated at times when it is not needed and not generated when it is needed. So we still have

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

2021-08-13 Friday! Free Hydrogen!
Ongoing argument! Ivan Rusev I fully understand the math behind what you’re saying. But I got through explaining why is doesn’t matter, and that fell on your deaf ears! You said, “…if you had no bias whatsoever…” Ivan it’s you that doesn’t have the open mind to give credence to other technologies than batteries. They’re

CATL has developed and produced sodium-ion batteries almost as good as LFP batteries. The 1st generation are 160 Wh/kg as compared to 200 for LFP. https://insideevs.com/news/523413/catl-unveils-sodium-ion-battery/amp/
2021-07-28 Concentrated Solar Power, Solar PV
Thread from FB << Michael Burns Concentrated Solar Power (CSP) is a totally different technology, which has a lot of operational advantages over PV, but still many disadvantages compared to other generation types. Functionally, CSP is simply thermal energy storage, so like a battery, when it’s “charged”, it can be included in the short term
