Piotrek Puczek said, “Nothing has been solved, hydrogen will only be for miche applications…” There are other catalysts besides expensive metals, but they may not be as efficient. But efficiency is not a concern when the power is excess that would otherwise be constrained – wasted, unused. There are Youtube videos of hydrogen generators that

This 4 day new LTT video about hydrogen EVs has a much more impartial view of hydrogen EVs. Elon calls hydrogen “… a staggeringly dumb form of energy storage…” But if you compare it to ICEVs, it’s nowhere near as bad. And right now, most vehicles are ICEVs using even more inefficient gasoline. Elon should

From a reply in FB group TSLA… Hydrogen fuel cell vehicles will be very common once the electric grids are powered predominantly by renewables. The price of hydrogen will conform to Wright’s Law and be so cheap that it will be competitive with BEVs. And due to the electric grid powering what is now still

The absurdity is overwhelming. https://www.renewableenergyworld.com/hydrogen/the-hydrogen-hype-bubble-may-have-finally-popped/ Quote: << Of course, green hydrogen’s current lack of availability isn’t the only reason it’s not the wonder-fuel the fossil fuel industry has been making it out to be, considering the following: … >> How can its “lack of availability” prevent it from being a wonder fuel? The problem today

This guy runs everything off hydrogen. He makes his own, stores his own and powers everything from green hydrogen. He has six patents dealing with hydrogen. He made his own system. https://youtu.be/NMH1pBAYgYs GKN Hydrogen’s HY2MINI demonstrator. This is a similar setup. The solar array powers the electrolyzer. The green hydrogen is stored in metal hydride

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

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

German company is marketing a hydrogen based energy storage system for residential use. Also heats water. It’s made for use with solar PV system. PICEA https://www.pv-magazine.com/2021/06/11/hydrogen-based-storage-system-for-residential-applications/
From FB group reply Andrew Roddy You failed to state the obvious. Hydrogen, despite its inefficiencies, is more efficient in FCEVs than fossil fuel in ICEVs. And its distinct advantage for heavy transportation is the refueling time can be the same as fossil fuels. See charts below. One more pro for hydrogen efficiency, see this

This short story gives the price of a Lavo green hydrogen fuel cell system as AU$35,000, I’m assuming it’s Australian dollars. It says the system is good for 30 years. https://amp.9news.com.au/article/4cb3ebca-0515-419a-b298-ee491bbccb2f Here is JHAT channel’s video about it. Skip first 2 mins. https://youtu.be/0_bTjcjqN6c A comment in the above video said this (quote): << owmid 6rgy.
